What you’ll be working on

- Diving into kernel traces to profile and performance engineer a high-throughput Sessions API
- Working across VMs, proxies, caches, task queues, and orchestration systems
- Building observability, CI/CD, and operational tooling from the ground up

What we’re looking for

- 4+ years of experience writing high-quality production code
- Strong background in large-scale distributed systems
- Hands-on experience with cloud infrastructure (AWS or GCP)
- Deep understanding of OS fundamentals (Linux, filesystems, containers, networking, etc.)
- Strong performance engineering instincts (latency, throughput, profiling, optimisation)
- Rust experience is a plus, but not required

What’s in it for you

- Work on real, high-scale systems with meaningful production load
- Get close to the low-level performance and infrastructure layer (not just application code)
- Solve hard problems around distributed orchestration, virtualization, and latency at scale
- Join a small, high-ownership engineering team where your work has direct impact
- Build infrastructure that sits at the intersection of AI systems and the contemporary web
