Job description
The Role
We are looking for a high-agency Software Engineer to help build the core systems behind ConstellationOS — the autonomous operating system for satellite networks.
You will work directly with the founders to design, implement, and scale distributed systems that process real-time telemetry, predict network failures, and autonomously reroute mission-critical traffic.
This is not a narrow feature role. You will operate across backend infrastructure, performance-critical systems code, cloud architecture, and operator-facing tooling. You will also engage directly with customers in forward-deployed environments.This role is based in Seattle, WA.
What You'll Do
Distributed Systems Architecture:
Design and implement fault-tolerant backend systems capable of ingesting and processing high-throughput real-time telemetry streams.
Performance-Critical Engineering:
Build and optimize low-latency components in C++ and Rust. Own performance profiling, concurrency design, and system-level optimization.
Cloud & Infrastructure:
Develop and operate cloud-native infrastructure (AWS or equivalent), ensuring scalability, observability, and reliability.
Full-Stack Contribution:
Contribute to operator-facing frontend systems when needed to ensure seamless integration between backend intelligence and mission control interfaces.
Forward-Deployed Engineering:
Work directly with customers in live operational environments. Integrate, debug, and iterate rapidly based on real mission feedback.
Systems Optimization:
Continuously improve throughput, reliability, and autonomous decision-making performance across the ConstellationOS platform.
Who You Are
High Agency:
You do not wait for tickets. You identify bottlenecks, propose architectures, and execute.
Systems-Minded:
You deeply understand distributed systems, networking, operating systems, and concurrency.
Low-Level Fluent:
You are comfortable writing and debugging performance-sensitive systems in C++ and/or Rust.
Cloud Native:
You have experience deploying and operating distributed systems in modern cloud environments.
Customer-Ready:
You are comfortable interfacing directly with technical customers and operating in forward-deployed settings.
Startup-Calibrated:
You thrive in high-velocity environments where ambiguity is normal and impact is immediate.
Bonus:
Experience in AI systems, satellite networking, real-time telemetry, or hard-tech environments.
Compensation
Base salary:
$120,000 – $180,000 USD
Meaningful equity participation
Competitive benefits
Compensation is commensurate with experience, technical depth, and demonstrated systems expertise.
