50 Side Project Ideas for Engineering Managers in 2026
By Cristian Lascu · The Sovereign Technologist
Most engineering managers have more leverage than they realise — their skills solve problems people are actively willing to pay for. The challenge is knowing where to start. These side project ideas are ranked by difficulty and revenue potential, based on what's actually working for technical professionals building income outside employment in 2026.
Starter Side Projects for Engineering Managers

Pro tips
- →Start with something you'd build anyway for your own use. The best side projects solve a problem you personally experience — your domain knowledge reduces risk dramatically.
- →Don't wait for a perfect idea. Ship a 'good enough' version in 4 weeks and let real users tell you what to build next. Most successful side projects look nothing like the original idea.
- →Choose a distribution strategy before you write a line of code. 'If you build it they will come' is how most side projects die. Who specifically will use this, and how will they find it?
- →Price higher than feels comfortable. Engineering Managers consistently undercharge. If your first 10 customers didn't push back on price at all, you're underpriced by at least 50%.
- →Protect your energy. A side project that requires 40 hours a week is just another job. Pick something that can move meaningfully on 5–10 hours a week, at least at the start.
