Hello

Por favor, verifique que tiene el nivel de experiencia y las cualificaciones adecuadas leyendo la descripción completa de esta ocasión a continuación.

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?

About the team

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.

We're a team of 200+ Product Engineers building a Business Management solution that actually works for the people using it. Our core stack is Ruby on Rails and React, but the interesting work right now is what we're building on top of that: agentic workflows, LLM-integrated features, systems that behave probabilistically rather than deterministically.

We believe that strong fundamentals, adaptability, and the ability to leverage modern tools, including AI, are what truly matter.

What are we looking for?

You're a strong engineer fi
