At Factorial, we're looking for an Engineering Team Lead who still writes code. To be clear about what this role is: it's a player-coach job. If you're looking for a role where you lead from a distance and spend the week in planning meetings, this isn't it.
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.
Our Engineering team is the engine behind Factorial, crafting the tech that makes HR simple, fast, and reliable for thousands of companies. If you love solving hard problems and want to build something that truly matters, come build it with us.
You've mentored engineers, and you enjoyed it more than you expected.
You'd rather solve the problem with the team than hand it over and check in later.
Solid full-stack experience shipping and maintaining production software.
You still code regularly, and you want to keep it that way.




Strong experience designing APIs (REST, GraphQL, etc.) You've run into scalability, performance, and quality as real constraints in production, and worked through them.
You can read an unfamiliar codebase and be useful in it quickly.
Being a great Engineering Manager at Factorial means caring about more than the code. You know when to ship something imperfect and when to slow down and get it right.
AI-native engineering and product mindset
We expect our engineering leads to build AI-powered products, not just use AI tools on the side.
You treat AI as a core part of modern software engineering, not something you bolt on at the end.
You've built or contributed to AI-powered features or workflows that made it to production.
You know what good AI development looks like in practice: defining behaviour and success criteria before you build, measuring output quality, grounding systems in real data,
