Modeling and Simulation Engineer - Optical

About the Team

The Seeker Team builds the eyes and the targeting logic of our weapon system: a low-cost, mass-producible, multimodal missile seeker that leans on commercial supply chains where they outperform, and vertically integrates wherever possible. On a modern missile, the seeker is 40 to 60% of unit cost and often drives overly long delivery cycles; accordingly, the seeker team is at the tip of the spear for delivering capability to our customers and value to the taxpayer.

Seeker design has exactly two real constraints: physics and mission. Nothing else is a show-stopper, only an obstacle to overcome. We are a small, deeply technical team that drives capability through ingenuity and bias for action and ships hardware that flies. This is a wear-many-hats environment where you must be comfortable "building the airplane in flight" and stepping well outside your comfort zone; a narrowly scoped role with clean handoffs is not what this team offers.

This is an AI-native team. Through fluent use of cutting-edge agentic coding tools, one engineer here consistently out-delivers a much larger conventional team. You will have opinions about where these tools help and where they do not, provide governance input, and build out an AI-centric workflow from day one.

About the Role

You build the team's real-time, physics-based engagement simulation and the target signature models used in it. You also build the end-to-end performance model from photon to processed image. That model predicts what the seeker will see before the hardware is designed or purchased. After every test and flight, it accounts for the difference between that prediction and the measured data. You work in tight partnership with the Seeker Data and Tooling Engineer, who builds the training-data pipeline and the compute under that simulation. You determine whether a rendered photon is physically correct. They build the machinery that turns that physics into datasets and throughput.

What You'll Do

Own the team's real-time, physics-based engagement simulation pipeline: scene, sensor, signal chain, and engagement logic, correct at speed.

Build and validate signature models for target hardbody and plume/exhaust phenomenology.

Own scene generation physics: DTED and georeferenced terrain, frames, projections, and accuracy budgets.

Model the aero-optical environment at Mach 3 speeds and reconcile it with the optical error budget.

Build and maintain end-to-end seeker performance models spanning scene, atmosphere, optics, FPA, ROIC, ADC, signal chain, and image processing in MWIR and LWIR.

Run Monte Carlo trade studies on optical, sensor, and signal-chain parameters and translate the results into program-level design decisions.

Validate models against captured imagery from lab, ground, and flight tests, and hold physics sign-off on every synthetic dataset the algorithms team trains against.

Skills We're Hiring For

B.S. in Optical Engineering, Physics, EE, Aerospace, or related; M.S. or Ph.D. preferred.
