Ask a room of early-career engineers which part of the job they most want, and most will say building: new platforms, new pipelines, new products. Ask a room of senior engineers which colleagues they most trust, and the answers shift. The names that come up belong to people who keep things working: who notice the certificate before it expires, who retire the service nobody remembers owning and who can explain what is actually deployed without opening six dashboards. If you are thinking about your career in IT, the evidence points to a counterintuitive conclusion. Maintenance skills are among the most durable assets you can build.
Why upkeep is undervalued early and valued later
Early in a career, work is judged by visible output. A new feature is easy to demo; a quietly avoided outage is invisible by definition. Teams that reward only what can be shown reinforce the habit of building new things and leaving old ones to fend for themselves. Over time that debt accumulates, and the people who can pay it down become valuable out of proportion to how glamorous their work looks.
Hiring managers describe this pattern when they discuss what separates a competent engineer from a dependable one. Competence is knowing how to build. Dependability is knowing what happens to the build in eighteen months, and caring enough to plan for it. The second quality is rarer and harder to teach, which is exactly why it is worth developing deliberately.
The specific skills hiding inside maintenance
Upkeep sounds like a single chore, but it is a bundle of transferable abilities:
- Inventory thinking: being able to say what exists, where it runs and who owns it. This is the foundation of every later skill, and many organisations lack it.
- Risk judgement: deciding which update is urgent, which can wait and which deserves a rollback plan. This is applied reasoning rather than rote procedure.
- Safe removal: retiring components without breaking dependants, usually through staged shutdowns and communication.
- Verification: testing from the outside, including backups, restores and public-facing content, rather than trusting that something works because nobody complained.
- Documentation that stays true: writing notes concise enough to be kept current.
- Communication: explaining to non-engineers why a quiet week of patching is real work.
Look at a job description for any reliability-focused role and you will find most of these words in disguise. Our overview of the skills needed to manage cloud and DevOps work on real projects makes the same point from the project side: the day-to-day is far more about stewardship than about novelty.
Practising on your own initiative
You do not need a mandate to build these habits. A learner can start with a home lab or a side project and treat it as a miniature estate:
- Keep a plain list of everything you have deployed, even if it is only a few small services.
- Once a month, update what can be updated, and note what broke and what did not.
- Delete one thing that you no longer use, and write down how you made sure it was safe to remove.
- Test a restore from backup at least occasionally, not just the backup itself.
- Read your own documentation as a stranger would, and fix the parts that no longer match reality.
The monthly notes are the real product. They become interview material: concrete stories about decisions, trade-offs and mistakes, which carry far more weight than a list of tools. If you are working towards a formal path, the practices line up neatly with what a training route for reliability and operations teams typically covers.
One caution for ambitious learners: do not treat maintenance as a reason to avoid building. The strongest profiles combine both. Build something, then live with it for a while, because the lessons from year two are the ones that rarely appear in tutorials and that interviewers love to probe.
Publishing your work is part of the job too
Many learners keep a portfolio, a blog or a profile page that points to projects, write-ups and certificates. That page is itself a deployed asset, and it ages like any other. A project link that returns an error or a repository that was renamed leaves a poor impression on exactly the person you were hoping to impress. Treat your public links as something to verify regularly. A link-management platform can help here; URLSnow, for example, brings published links together and its automated health checks flag the ones that no longer respond, so the first to know about a dead address is you, not a recruiter.
What the evidence suggests about career trajectory
There is no precise measure of how much maintenance skill adds to earning power, and it would be unwise to quote one. What can be observed is the shape of the path. Engineers known for stewardship tend to be handed larger responsibilities because the cost of getting it wrong grows with scope. They are asked to lead migrations, because they know what the old system really does. They are asked to mentor, because they can explain why things are the way they are. And they are often the ones who move into architecture or management roles, because they have a view of the whole estate rather than a single corner.
There is also a protective effect. Roles built entirely on new-feature delivery can be fragile when priorities change. Skills in running, securing and simplifying systems are needed whether the company is growing or tightening its belt.
A reasonable way to frame it in interviews
When asked about your achievements, resist the urge to offer only launches. Describe a time when you looked at something that was working, questioned whether it should be, and acted. Perhaps you removed an unused service that was costing attention, found a failing backup before it mattered or rewrote documentation that had drifted from reality. These stories show judgement, which is what employers are really buying.
The sentence to aim for is simple: before building something new, I checked what already existed. It signals that you understand the long life of software, which is a far larger part of its existence than the launch day. Learn to love that stage and your career will be sturdier for it.
