About this role
Join a startup building ConstellationOS, an autonomous operating system for satellite networks that processes 100,000+ telemetry messages per second and makes real-time routing decisions. You'll design and build distributed systems where latency, correctness, and reliability directly impact physical network performance.
What you'll do
- Design and maintain a deterministic world model that ingests massive telemetry streams and enables network simulation and reasoning
- Build high-throughput, event-driven distributed systems targeting 100k+ messages/sec with strict latency and ordering guarantees
- Develop low-latency components in C++/Rust, optimizing concurrency, memory efficiency, and sub-second end-to-end reaction times
- Implement autonomous decision pipelines that transform predictions into actionable routing and scheduling choices under real-world constraints
- Deploy and operate systems in AWS with comprehensive observability for latency, throughput, and decision quality
- Work directly with customers in operational environments to debug live systems and iterate rapidly
What they're looking for
- Distributed systems architecture and design
- C++ and/or Rust proficiency
- Networking fundamentals and protocols
- Real-time systems and low-latency optimization
- Concurrency models and memory management
- AWS infrastructure and deployment
- Event-driven systems design
- Systems-level performance profiling
