The Role Constellation is looking for a versatile Software Engineer to build the backbone of our ground and simulation software. You will architect robust backend systems that allow our operators to communicate with, simulate, and track aerospace assets in real-time.
Responsibilities
Design and build highly concurrent, distributed backend services.
Develop data ingestion pipelines capable of handling high-throughput, low-latency flight data.
Create software tools and simulation environments used by internal teams for mission planning.
Write clean, well-tested code and participate in rigorous peer reviews.
Requirements
B.S. in Computer Science, Software Engineering, or related discipline.
3+ years of professional software development experience.
Strong proficiency in at least one modern backend language (e.g., Go, Python, C++, or Rust).
Solid understanding of networking, databases (SQL/NoSQL), and distributed systems architecture.
Skills Required
- Proficiency in C++ and/or Rust
- Experience designing and operating high-throughput, event-driven distributed systems (target ~100k+ msgs/sec)
- Deep understanding of distributed systems, networking, operating systems, and concurrency
- Experience with low-latency performance optimization, concurrency models, memory efficiency, and profiling
- Experience deploying and operating distributed systems in AWS (or equivalent)
- High-agency/startup mentality and ability to take ownership from design to production
- Ability to work directly with customers and debug live operational systems (forward-deployed engineering)
- Experience with event-driven architectures and streaming pipelines
- Background in networking protocols (TCP/UDP), routing, or distributed protocols
- Experience with simulation frameworks (e.g., Basilisk, ROS, Gazebo) or game engines
- Exposure to satellite systems, orbital data, ground segment infrastructure (SATCAT, TLEs, GSaaS)
- Experience running ML inference pipelines in production
What We Do
Constellation Space builds ConstellationOS, an AI-native operating system that forecasts satellite link degradation minutes ahead and autonomously reroutes traffic under policy to prevent data loss. The platform ingests telemetry, uses physics-informed ML to predict failures with high accuracy, and executes rapid, policy-bound reroutes to provide mission assurance and scalable orchestration for large satellite constellations.
