AI and the new junior engineer
Being somewhat of an AI sceptic, but having to deal with the advent of AI tooling and its impact on engineering productivity is weird. As is often the case, the other day I was engaging in some AI fear mongering when chatting with my colleague Kate. We got into it, especially the concerns about the future of junior software engineer roles. She made a valid point that many other industries have already navigated significant shifts due to automation (Kate - you legend).
I thought about this before, but Iâve always dismissed the comparison due to the state AI tooling was in. Google practically forced all its engineers to use AI tooling far before it was ready, and many of us have burned out, and many of us have very strong opinions of how garbage this technology is. But over the past year alone weâre now at the point where AI models - with some guidance - can perform many junior development tasks - like putting together a simple website or writing a hyper specific tool. Oh, and shout-out to my then-manager-now-retired-friend Patrick - whose (exclusive, I am very fancy) newsletter encouraged me to dig into how AI tooling has changed. Thanks Patrick, Iâll probably send this to you.
In fact, Gemini Pro even helped me with an outline of this article. These are still my own thoughts, typed out with my own two hands (I find angrily typing out my thoughts to be therapeutic and the best part of writing). But thereâs no writerâs block - Iâm not staring at a blank document anymore. In front of me is a stub of an article that I hate with a passion, and this burning hatred for the AI-authored stub is whatâs pushing me to write down my thoughts in one go.
You see, for a while I used to group AI with other tech trends like big data or blockchain - impactful technologies, but not something that fundamentally rewrote the playbook on software development. Yes, our databases are now order of magnitude larger, but weâre still using the same interfaces to engage with them - and itâs now just âdataâ. And blockchain, outside of niche problems, turned out to be a grift. No, AI is really closer to industrial revolution. And yeah, the news sources and many folks I know have been using these words have been saying this for years - but that just sounded too grandiose to be true. I couldnât see the forest of changing job landscape for the trees of not-quite-yet mature models. But I think itâs true: the means of production will evolve.
Anyhow, Kateâs comments prompted me to look into how others adapted when their familiar landscapes changed.
The idea that âjunior engineers wonât exist, so senior engineers wonât existâ has a simplistic appeal. However, it often overlooks how industries, and the people within them, actually progress. The software engineering career pipeline isnât necessarily breaking - itâs just getting rerouted through unfamiliar territory.
Letâs be clear: the old model, where experience was often gained through highly repetitive tasks, was never perfect. It was simply the established way, the way of our ancestors: software engineers learn some math and not-particularly-useful concepts in college (or take a coding bootcamp, which is much faster, and in my experience, produces similar results), join a company, shadow more senior engineers, write some terrible code, make a few expensive mistakes for the company to absorb, and eventually graduate into productive developers of software. But like any system with inherent inefficiencies, this progression system was always susceptible to disruption.
This kind of transformation isnât unique to software, and isnât unique to AI. And in my brief research I found many examples - here are the three representative example - one where the career pathways evolved, one where that path was closed, and one where it became easier.
The factories
Letâs get the factory floor comparison out of the way - itâs not great, but it sort of works.. Getting to start in manufacturing meant working on an assembly line, performing a repetitive task hundreds of times a day, being noticed by the supervisor, and eventually being promoted up the chain. Throughout the later part of the twentieth century, industrial robots became a thing - these were big, dumb robots, but they could do what a worker did more consistently, sometimes faster, but most importantly - for a constant lower cost, and without sick days or unions.
The junior roles on the factory floor have changed - itâs now all about monitoring, maintaining, and troubleshooting the machines. Many jobs shifted from the factory floor to the office - you needed your CAD operators and technicians. The pathway to becoming a manufacturing professional is no longer about enduring years of menial back breaking labor: itâs all about understanding and interacting with automated systems.
The career ladder, while different, is still there for those who were willing to make the switch.
Opportunities arenât better or worse - theyâre just different.
Banking
Bank tellers. For a long time bank teller was a potential entry point into the world of finance. Learn the procedures, handle cash, advance through the branch, and move onto corporate. Then the ATMs were introduced in mid-twentieth century (in a moment of vulnerability Iâd like to admit that I didnât realize that ATM stands for Automated Teller Machine). The need for accepting and dispensing cash has diminished.
The teller jobs changed. It wasnât about counting bills (and in fact, if youâve been to a bank recently and interacted with a teller - they donât really count the cash for you). The job didnât die out, but is mostly about customer service and selling products for the bank.
With a change to tellerâs role - now mostly of a customer service representative and a salesperson - a direct path from teller to a finance analyst is mostly no more. A finance degree and proficiency with financial software are whatâs advantageous here, with the teller counter experience becoming irrelevant.
The door closes. Actually, the doorâs been bricked up altogether.
Photography
Now for something that might have actually gotten better for folks trying to break in: photography. Ask your parents (or grandparents if youâre Gen Alpha) â about becoming a pro photographer pre-digital. It was a mission: you needed a darkroom, which meant space and a boatload of chemicals that probably werenât doing your health any favors. Equipment cost an arm and a leg, film was pricey, and developing film was a whole other cost and skill. Youâd need to wait hours or days to see if those expensive shots were any good. Apprenticeships were common because the barrier to entry, both in cost and arcane knowledge, was sky-high.
Then digital cameras, especially affordable DSLRs in the 2000s and eventually decent smartphone cameras changed the industry. Suddenly thereâs no more darkroom alchemy - with Photoshop your house no longer smelled like a chemistry set. The learning loop shortened from hours or days to seconds: take a picture - look at the screen - delete - take another picture, and abundant online tutorials make learning free and accessible for all. S
Even distributing your work is easier - no longer do you need to contact a publisher or beg a gallery to look at your prints. Instagram, Flickr (is that still a thing?), and other photo sharing sites allow you to reach global audience in a few clicks. Yes, the marketâs flooded, and everyone and their mother are a photographer now. Experts still do stand out in the sea of amateurs, although itâs definitely much harder to do so. But the pathway to learning the craft and getting the audience has been democratized.
Knowledge is widely accessible, and entry costs are significantly lowered.
A common pattern emerges: the mundane, the highly repetitive, the work that served as âexperience buildingâ largely through sheer volume â thatâs what tends to get automated. And as a software engineering manager, thatâs what I usually leverage junior engineers for. And thatâs not setting them up for success - oh no itâs not.
So, what does this mean for software engineering, and what can we practically do?
Think about the evolution of programming itself. We moved from wrestling with machine code and assembly to C, where we gained more expressive power but still had to meticulously manage memory. Then came languages like Python or Java, which abstracted away much of that lower-level complexity, allowing us to build applications faster and focus on different, often higher-level, business problems. Each step didnât eliminate the need for smart engineers; it changed the nature of the problems they focused on and the tools they used.
This AI transition feels like another such leap - albeit somewhat more dramatic - and there are more tech bros, and some of the NFT drifters have joined too. Which, combined with the costs and rough edges, makes it harder for some of us to see the value behind the technology. Yet, weâre getting a new set of incredibly powerful, high-level tools. The challenge isnât that the work disappears, but that the valuable work shifts to orchestrating these tools, designing systems that incorporate them, and solving the new classes of problems that emerge at this higher level of abstraction.
If the common understanding of a junior software engineer is someone who primarily handles boilerplate code, fixes very basic bugs, or writes simple unit tests that could be script-generated, then yes, that specific type of role is likely to disappear. That work was more about human scripting than deep engineering.
The career path isnât vanishing; itâs demanding different skills, often earlier.
For junior developers
Frankly, the advice for junior developers hasnât really changed. Unlike Steve Yegge, I still think you should learn Vim though.
- Learn the tools: Your early-career work will increasingly involve interacting with AI-generated code, understanding its structure, integrating it, and debugging the subtle issues that arise. Developing effective prompts, validating AI outputs thoroughly, and fine-tuning models for specific tasks will be valuable skills. This is still foundational work, but it requires a different kind of critical engagement.
- Get good at learning: Tools and AI models will evolve quickly. The ability to teach yourself new paradigms efficiently is crucial. Focus on the underlying principles of software development; they tend to have a longer shelf life than specific tools.
- Develop scepticism: Donât implicitly trust AI outputs. Your value will increasingly stem from your ability to critically evaluate, test, and verify what machines generate. Seek to understand why a tool produced a particular result.
- Practice: Theory is essential, but practical application is where deep learning occurs. Use these new AI tools to build something non-trivial. The challenges you encounter will be your best teachers.
- Tread with caution: Your senior peers might be sceptical of AI tooling. Thereâs a lot of hype, and senior developers have been through many hype cycles - I know I have. Show, donât just tell, and be prepared to defend your (AI-assisted) work rigorously.
For senior engineers and managers
These are the steps my peers and I should be taking to set up those in our zone of influence for success.
- Adapt: Your role isnât to shield junior colleagues from AI but to guide them in using these powerful tools effectively and ethically. This requires you to understand these tools well. Mentorship will likely focus more on system-level thinking in an AI-augmented environment.
- Re-evaluate skills: Consider how AI changes the value of certain traditional skills. Is deep expertise in a task that AI can now perform rapidly still the primary measure, or is the critical skill now defining problems effectively for AI and integrating its solutions? Your metrics for talent should adapt.
- Engage with tools: To lead this transition, you need firsthand experience with these tools. Understand their capabilities, limitations, and common failure modes. This practical knowledge is essential for making informed decisions and guiding your teams.
- Redesign tasks: Phase out giving juniors only the highly repetitive tasks that AI can now handle. Instead, structure initial assignments around using AI tools for leverage, then critically evaluating, testing, and integrating the results. Their first âwinsâ might be in successfully wrangling an AI to produce a useful component, then hardening it.
- Teach AI skepticism: Donât assume junior developers will know how to question AI. Make it a core part of their training. Ask them to find the flaws in AI suggestions, to explain why an AI output is good or bad, not just that it âworks.â
True engineering skill has always been about problem decomposition, understanding trade-offs, systems thinking, debugging complex interactions, and delivering value (to shareholders). AI doesnât negate these fundamentals; it changes the context in which we apply them and the leverage available.
New engineers often lack deep context and the experience of seeing systems fail. AI wonât provide that - in fact itâll make it harder to spot a lack of fundamental understanding.
The path to seniority wonât be about avoiding AI; it will be about learning to master it, question its outputs, and work strategically with it. It will require fostering critical thinking and deep systems knowledge to use these powerful tools wisely.
The old ways of gaining experience will not disappear - they will evolve. The challenge is to define what skill looks like in this new landscape and ensure our learning pathways effectively build it.
The future will need senior engineers; they will be the junior engineers of today who navigated evolving technological terrain and learned to harness its potential. Itâs time to start mapping that new path.
