Staff Engineer

Responsibilities:

• Own Architect Agent Infrastructure: Design the systems that allow autonomous agents to plan, reason, execute, recover from failures, and continuously improve.
• Build for Planetary Scale: Develop backend and infrastructure systems supporting millions of applications, billions of agent actions, and globally distributed workloads.
• Solve Reliability for Non-Deterministic Systems: Create new approaches for validation, observability, debugging, evaluation, and fault tolerance where traditional software engineering assumptions no longer apply.
• Drive Technical Direction: Set architectural standards across infrastructure, platform, agent runtime, and distributed execution systems.
• Create New Engineering Paradigms: Many of the challenges you'll face don't have established solutions. You'll be expected to invent them.
• Raise the Bar: Influence engineering culture, mentor senior engineers, and help build one of the highest-talent-density engineering organisations in the industry.

Requirements:

• We're less interested in specific technologies and more interested in how you've thought about hard systems problems.
• 5+ years building large-scale distributed systems.
• Experience owning architecture for critical production infrastructure.
• Deep expertise in concurrency, distributed computing, reliability, performance, and fault tolerance.
• A history of driving technical strategy across multiple teams.
• Strong backend expertise in Go, Python, Java, C++, Rust, or similar languages.
• You may have worked at companies like Google, Uber, Meta, Databricks, Snowflake, Airbnb, Stripe, Dropbox, Amazon, Microsoft, or exceptional high-growth startups.
• Experience With AI Systems Is Helpful But Not Required.
• Exceptional systems engineers learn fast.

Who Thrives Here:

• Engineers who prefer first-principles thinking over established playbooks; builders who want ownership rather than coordination; people who enjoy solving ambiguous, unsolved technical problems; engineers who optimise for impact, not titles; individuals who want to help define an entirely new category of software.
