Principle Software Engineer

This is not a traditional Staff Engineer role. You won't be optimising APIs, managing microservices, or incrementally improving existing infrastructure. You will help define the architecture of systems that can eventually replace large portions of the software development lifecycle itself. You'll Work On Problems At The Intersection Of Distributed systems, autonomous agents, reliability engineering, program synthesis, large-scale infrastructure, runtime execution environments, verification, and correctness. The systems you build will influence how millions of applications are created.
Responsibilities:
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.
