About the role
Role
We are looking for a high-agency Principal Wireless Engineer to be the ultimate authority on the physics and RF dynamics of our simulation engine. You will work directly with the founding team to architect the mathematical models that allow our software to accurately predict how, when, and why satellite and ground station links degrade. Your work will directly translate into the core logic of ConstellationOS, ensuring our predictive capabilities hold up in high-stakes commercial and defense deployments.
What You’ll Do
- Own the Physics of Failure: Develop the mathematical models and algorithms that simulate complex SATCOM and terrestrial network degradation. You will account for Doppler shifts, dynamic handovers, latency spikes, and hardware constraints across varied orbital regimes.
- High-Fidelity Environmental Modeling: Drive the integration of high-resolution weather and atmospheric datasets (e.g., ERA5, GOES-R, ASOS) into our simulation engine to accurately model rain fade, scintillation, and tropospheric/ionospheric interference.
- Bridge Science and Software: Translate deep physics, RF constraints, and link budgets into actionable architectural logic. You will collaborate closely with our engineering team to ensure your models are seamlessly integrated into the ConstellationOS codebase (Python/C++/Rust).
- Applied Research & Edge Cases: Analyze data from our active commercial pilots and defense evaluations to continuously validate and refine our simulation's realism against real-world telemetry.
Who You Are
- The Domain Expert: You hold a PhD (or possess equivalent industry experience) in Physics, Electrical Engineering, Aerospace Engineering, or a closely related field, with a deep focus on RF propagation, SATCOM, or atmospheric science.
- Systems-Level Thinker: You understand traditional terrestrial networking (BGP, OSPF, MPLS) and how it intersects with space-based routing. You know how packets move and the exact physical phenomena that cause them to drop.
- Relentlessly Resourceful: You thrive in the unstructured environment of a seed-stage, hard-tech startup. You are a "problem-finder" who can independently identify gaps in our models and build the mathematical solutions without waiting for a roadmap.
About Constellation Space
Constellation Space is building the autonomous infrastructure layer for the next generation of space networking. As satellite constellations rapidly scale from hundreds of nodes to tens of thousands, traditional ground-based orchestration fundamentally breaks down. ConstellationOS bridges this gap by providing zero-intervention network handoffs, predictive thermal load-balancing, and sub-second optical routing.
Our founding team spent years building and operating satellite systems at SpaceX, Blue Origin, and NASA. We started Constellation to solve the problem we kept running into: reactive monitoring doesn't scale.
We are building the sub-second routing protocols and hyperscale load-balancing infrastructure that will manage the future of off-world telecommunications and compute.
