Hello!

At Factorial were 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. Its genuinely hard and its genuinely exciting.

If youre someone who gets energy from working closely with the business growing engineers around you and using AI not as a buzzword but as a real tool to build better products faster - wed 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.

Were 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 were 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 bring both leadership experience and a modern AI-native engineering mindset.

• Youve managed people before and helped engineers grow ideally beyond your own level.
• Youve been part of hiring processes and have a track record of bringing strong people into your teams.
• Youre comfortable working across teams and contributing to shared platform and service foundations.
• You engage in honest Socratic discussions focused on finding the best solution not winning the argument.

Experience and Technical Depth

• 5 years as a Full-stack engineer or similar role.
• 3 years leading engineering teams.
• Strong experience designing APIs (REST GraphQL etc.) and building integrations.
• You understand scalability performance and quality as real constraints and have dealt with them in production.

Business Mindset

Being a great Engineering Manager at Factorial means caring about more than the code. You understand the business context behind what youre building and can connect technical decisions to real outcomes for customers and the company.

• Youre curious about how the business works and use that understanding to make better technical calls.
• You push your team to understand the problem deeply before jumping to solutions.
• You think in terms of customer value not just technical deliverables.
• Youre comfortable talking to stakeholders asking hard questions and challenging assumptions when something doesnt add up.
• You know when to ship something imperfect and when to slow down and get it right.

AI-Native Engineering and Product Mindset

We 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.
• Youve 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 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 thats coding testing debugging or documentation.
• You can help your team review validate and safely ship AI-generated code and behaviours.
• You understand the real limitations of LLM-based systems: hallucinations evaluation challenges data sensitivity.
• You create space for experimentation and fast learning loops within your team.
• You spot opportunities where AI can genuinely simplify something complex and create real value for users.

What Youll Be Doing

• Youll start with a buddy who guides you through some non-critical tasks to get comfortable with the codebase.
• Youll learn the business the full customer journey and work with the team to draft a roadmap.
• Youll join weekly team meetings to discuss priorities and bring new ideas to the table.
• Youll review the RFCs your team produces give feedback and push for the best way to get things done.
• Youll hire as the team grows making sure we bring in people who are both talented and good-hearted.
• Youll constantly look for ways to improve how the team works.
• Youll run weekly 1:1s focused on the development and well-being of each person on your team.
• Youll work with other engineering managers to coordinate initiatives that cut across teams.
• Youll 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.
• Youll convince or get convinced. Youll hear that a lot.
