At Factorial, we're looking for an Engineering Manager who wants to get their hands dirty - someone who leads teams but stays close to the work, understands the domain deeply, and cares about shipping things that actually matter.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. ðAbout the team ðOur Engineering team is the engine behind Factorial, crafting the tech that makes HR simple, fast, and reliable for thousands of companies. We're a team of 200+ Product Engineers building 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.You bring both leadership experience and a modern, AI-native engineering mindset.Experience and Technical Depth5+ years as a Full-stack engineer or similar role.3+ years leading engineering teams.Strong experience designing APIs (REST, GraphQL, etc.) You understand scalability, performance, and quality as real constraints and have dealt with them in production.Business MindsetBeing a great Engineering Manager at Factorial means caring about more than the code.

AI-Native Engineering and Product MindsetWe expect Engineering Managers to lead teams building 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 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, designing workflows that can take safe and auditable actions, and knowing when to keep humans in the loop.You use AI-assisted tools to move faster in your day-to-day,



whether that's coding, testing, debugging, or documentation.You understand the real limitations of LLM-based systems: hallucinations, evaluation challenges, data sensitivity.You'll work with other engineering managers to coordinate initiatives that cut across teams.You'll help lead the shift to AI-native product development, not by mandating tools, but by setting the example, asking the right questions, and creating the space for your team to experiment and learn.How We Work ð» (Barcelona or Madrid Office)At Factorial, we believe the best products are built when people come together, in person to collaborate, challenge ideas, and move fast.
