Senior Site Reliability Engineer

What’s it like to work at Attio?

At Attio, excellence isn't just encouraged — it's expected. We're not building just another SaaS app: we're creating the fundamental infrastructure for the next generation of businesses.

We're builders who come together to create something greater than any of us could achieve alone. We take pride in pushing boundaries, obsessing over details, and continuously raising our standards. The scale of our engineering challenges reflects this — we're tackling problems that require rethinking how business software is built from first principles. Every day, we work in sync to solve complex challenges through rigorous collaboration and unwavering focus on quality.

We move quickly but thoughtfully, focused purely on creating exceptional work. When you join engineering at Attio, you're joining a team that believes in relentless execution, measurable results, and collective achievement. We challenge each other's work rigorously while supporting each other completely, making decisions fast while also pushing the boundaries of what's possible.

This is a rare opportunity to help create the foundation for how modern businesses will operate. You'll solve fundamental technical challenges that will shape how the next generation of companies are built, setting the standard for decades to come.

About our team

Attio Engineering is organized into small product teams (3-4 engineers plus a designer) that independently own sections of the product. Our engineers are empowered as Product Engineers, with work extending beyond code to full ownership of product impact.

Our culture rests on two principles: Curiosity and Ownership.

• Curiosity: Open access to our business metrics, customer conversations, codebase, and tooling. Everyone has a voice and is encouraged to question any part of the business.

• Ownership: Each team is fully responsible for their product area, from managing technical debt to planning features. Decision-making authority lies at the team level, allowing for agile and impactful development.

Our engineering team is currently 25 strong, a size where individual contributions shape both the product and our culture.
