About this role

Software Engineer Seattle | OnSite THE ROLE We are looking for a high-agency Software Engineer to help build the core systems behind ConstellationOS - an autonomous operating system for satellite networks. ConstellationOS is not a traditional backend system. It is a real-time, closed-loop decision engine that: - Ingests 100,000+ telemetry messages per second - Maintains a deterministic world model of a live satellite network - Predicts link degradation and network failures ahead of time - Generates and executes autonomous rerouting decisions under real-world constraints This is a system where software directly interacts with a physical network. Latency, correctness, and reliability are not abstractions-they determine whether the system works. You will work directly with the founders to design and build systems at the intersection of distributed systems, networking, and real-world physical constraints. This role is based in Seattle, WA. This role is best suited for engineers who enjoy working on complex systems with real-world constraints. It is not a good fit for engineers looking for purely CRUD or API-focused work. WHAT YOU'LL DO Real-Time Systems & Digital Twin - Build and evolve the core “world model” of a satellite network, combining telemetry, predictions, and system state into a deterministic, queryable system - Design systems that can replay, simulate, and reason about network behavior over time Distributed Systems Architecture - Design and operate high-throughput, event-driven systems (target: 100k+ msgs/sec sustained) - Ensure strict guarantees around latency, ordering, and system stability under load Performance-Critical Engineering - Build low-latency components in C++ and/or Rust
