Senior Backend Engineer (Runtime Team)

We are looking for an experienced, hands-on Senior Backend Engineer to join the Runtime team - one of the most critical backend teams .
We are at a breakthrough stage, building our dream team with the most passionate and professional people in the industry.
The Runtime team owns the execution layer of all automations - the core of our product. We operate at a significant scale: hundreds of millions of steps and millions of security events every single day, in systems that simply cannot break. This creates constant challenges around scale, reliability, and forward-thinking design - always asking what could break next and how to prevent it before it happens. Beyond maintenance, there's a lot of innovation here, including supporting all of our AI-powered capabilities.
What Will You Do?
Take part in all development aspects - from design to production - of our high-scale automation runtime
Lead the design and implementation of features and architectural changes that keep our platform reliable at massive scale
Drive significant cross-team projects and influence decisions beyond your immediate team
Lead production incidents and post-mortems, raising the bar for stability and operational excellence
Mentor team members, take part in interviews, and help grow the team and its standards
Work with modern AI tools (Cursor, Claude Code) as a core part of the workflow - focusing more on design, review, and impact, while maintaining deep understanding and high-quality standards through hands-on code review
