Skills by role
Writing more code is rarely what gets an engineer to senior. The next level expects you to lead a piece of work, bring other people along and make the engineers around you better. Here is the skill set GapFix maps for the Senior Software Engineer role, and a 2-minute scan that labels each one for you.
The scan is free and needs no account. In the app: 7-day Pro trial, no card, no auto-charge.

These are the leadership and soft skills in the role model GapFix builds for Senior Software Engineer, heaviest first. The skill names are the scan's own. The two columns beside them are ours: what each one looks like at this level, and the usual sign that it is a gap.
| Skill | What “Strong” looks like at work | Typical gap signal |
|---|---|---|
| Stakeholder Management | Your product manager and the teams that depend on your service hear about a slip from you, early, with options. Nobody is surprised at the demo. | You report status only when asked, and trade-offs get decided for you. |
| Team Leadership | You lead a feature or an incident end to end without the title: you split the work, unblock others and own the outcome. | You deliver your own tickets well, but someone else still coordinates the project. |
| Mentoring | A newer engineer is clearly better because of you. Your reviews teach the why, and you pair on the hard parts. | Your code reviews fix the code, but the author learns nothing from them. |
| Cross-Functional Collaboration | You work out the requirements with product, design and QA before the code is written, and they ask for you by name. | You build what the ticket says and hear about the mismatch after release. |
| Industry Networking | You know how other teams and companies solve the problems yours has, and you bring it back: a write-up, a talk, a contact. | Everything you know about good engineering comes from your current codebase. |
The scan also checks the craft of the role. For Senior Software Engineer that means:
The list is much the same for everyone who picks this role. Your gaps are your own. The scan reads your CV against this role and labels every skill Missing, Needs work, Refresher or Strong, with a role-fit % on top. It takes about 2 minutes and needs no account.
To show what a plan looks like, we ran the scan for a made-up CV: a software engineer with 4 years of backend experience at a logistics software company. It scored 72% role-fit for the Senior Software Engineer role. Below are the skills that report labelled Missing and Needs work, and the twelve weekly themes of the plan the app built from it, word for word. Your plan is built from your own CV, so your weeks will differ.
Sample report · 72% role-fit
Each week has 7 daily focuses. The lesson for each takes about 13–15 minutes (scenario decisions, AI roleplay and rewrite drills), with further tasks sized to the hours you choose and a weekly quiz. The plan is in the GapFix iPhone app.
A report is built from one run of the role model and from the CV itself, so it can name a skill that is not in the list above.
GapFix builds the role model fresh each time someone runs the scan, so the list can vary a little from one scan to the next. To get a list we can stand behind, we ran it 3 separate times for Senior Software Engineer on 3 October 2026 and kept only the skills that came back at least twice. Of the 17 skills on this page, 11 came back all 3 times and 6 came back twice. Nothing was added or renamed. Your own report may include a few more.
There is no fixed time. It depends on your company’s level guide, its review cycle and whether there is a project you can lead from start to finish. What you control is the evidence. The GapFix plan is 12 weeks of practice, about 15 minutes a day, aimed at showing these skills at work.
