Being senior means focusing not only on hard technical problems, but also on opportunities to demonstrate meaningful impact.
A senior engineer often builds a kind of micro-framework (a workflow and system) that enables the team to develop effectively. They need to be a trailblazer.
Becoming an architect, project lead, product owner, or manager isn’t because someone “can’t code”; it’s the path of becoming the kind of person the organization trusts to own design and make sound decisions.
If you become senior only because you’re constantly chasing deadlines, that’s just a sign of insufficient skill. And when there’s work the team can’t deliver with its current capabilities, you should be able to take responsibility and implement it yourself.
- Technical leadership
- Execution/operational leadership
- A productivity advantage
- Solving genuinely hard problems
English becomes much more important as your career grows and you become a senior engineer.
You have to lead a team and represent it as a leader/manager to achieve key business goals—and represent your teammates during performance reviews and promotion committees.
Beyond “survival English,” you need polished, advanced English: to influence other teams, present your team’s achievements with confidence, and sometimes even deliver speeches that motivate people.
Five takeaways from looking for a new senior role in tech
A few months ago, I left SeatGeek without much of a plan of what to do next. My green card was finally issued in 2021, which means that I didn't have to scramble to find a new job in forty days.

The Senior Shift
In most tech companies, the first few levels of an engineering career ladder are pretty straightforward. You must grow from someone who needs a lot of oversight to an independent engineer. You need to develop your best practices and have evidence that your code is of high quality.

A senior role is not about blocking every bad project, but rather strategically preserving credibility and using influence only at truly critical moments.
Why Senior Engineers Let Bad Projects Fail
When I was a junior engineer, my manager would occasionally confide his frustrations to me in our weekly 1:1s. He would point out a project another team was working on and say, “I don’t believe that project will go anywhere, they’re solving the wrong problem.” I used to wonder, “But you are very senior, why don’t you just go and speak to them about your concerns?” It felt like a waste of his influence to not say anything. So it’s quite ironic that I found myself last week explaining to a mentee why I thought a sister team’s project would have to pivot because they’d made a poor early design choice. And he rightfully asked me the same question I had years ago: “why don’t you just tell them your opinion?” It’s been on my mind ever since because I realized I’d changed my stance on it a lot over the years.
