We're on a mission to change the way businesses make decisions with our cutting-edge AI technology. To achieve that, we’re looking for passionate people to join our open and inclusive workplace. Our inclusive environment welcomes skills and experiences from diverse backgrounds, and defines who we are.
We're hiring an SRE to help us run and evolve the infrastructure behind Signal AI's decision intelligence platform.
You'd be joining a small, collaborative Infrastructure team at a moment when the work is genuinely changing shape. Over the last year we've hardened the platform, reduced cost, and built serious observability into our highest-volume systems. The next year is about scaling that work, absorbing infrastructure from a recent acquisition, and being thoughtful about how AI shows up in operational work: not as a gimmick, but as a tool we trust ourselves to use well.
We're looking for someone who wants to shape the direction of the team; someone who brings curiosity and care to the work, and who wants to leave things meaningfully better than they found them.

Your first six months
We want to set you up to thrive. Here's what that looks like in practice:
What We’re Looking For
You have solid AWS and Terraform experience, and you're comfortable writing Python or Go to solve operational problems. You think in distributed systems: failure modes, observability, blast radius: and you take problems end-to-end rather than stopping at the edges of your own work.
You're pragmatic about AI tooling. Not evangelical, not dismissive. You can tell us when you'd reach for an LLM and when you wouldn't, and you'd have a clear reason either way.
You communicate openly and you're comfortable pushing back when you think something could be better. We want to leverage your experience and perspective to grow our platform.
We know not every strong candidate will have every skill on this list. If you're excited about the work and you're close on the experience, we'd encourage you to apply.
Nice to haves
Not sure you meet every requirement? Studies show that women and other underrepresented groups often hesitate to apply unless they check every box. At Signal AI, diverse perspectives strengthen our teams, drive innovation, and lead to better performance. So even if your background doesn’t align perfectly with each qualification, we encourage you to apply if you’re passionate about this role.
We're dedicated to creating an inclusive environment where every Signaller feels welcomed, valued, and heard—a place where you can truly thrive as yourself.
