Hello

At Factorial, we're looking for an
Engineering Team Lead who still writes code
. You'll lead a small team of 4–7 engineers, stay deep in the codebase, and own a product area end to end.

To be clear about what this role is: it's a
player-coach
job. You review PRs, pair on hard problems, and ship features yourself, while also running 1:1s and helping the people around you grow. If you're looking for a role where you lead from a distance and spend the week in planning meetings, this isn't it.

We're at an interesting moment. AI isn't a feature we're adding to our product, it's changing how the product works. That means rethinking how we design and build software from the ground up, moving from deterministic systems to AI-powered workflows that help real businesses run better every day. It's genuinely hard, and it's exciting.

If you get energy from building alongside your team, working closely with the business, and using AI as a real tool rather than a buzzword — we'd love to meet you.

Ready to be part of the challenge?
