FEED

Hands-on with agentic coding tools (Claude Code, Codex, OpenCode, Kilo, or similar): building, supervising, and reviewing AI-agent output to accelerate engineering work, with concrete examples of what you've shipped. 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.

Write the channel side of the laser transmitter specification and ICD: pulse energy, pulse width, repetition rate, timing jitter, linewidth and coherence, divergence, and the seed format a seeded MOPA amplifier must preserve (seeds are bought off the shelf). Integrate the transmitter into the channel: trigger and synchronization, the swap-ready source interface that lets a bought laser be replaced by our own without redesigning the channel, and, with the opto-mechanical engineer, shared apertures, boresight, and stray light.

Optical Engineer (Laser Systems)

You will own the aerodynamic model and the vehicle outer mold line: body shape, control surfaces, static margin, and the pipeline that turns geometry into the coefficient tables plant and flight software consume. America is critically deficient in production of defensive munitions- we currently produce shipborne interceptors in the few hundreds per year while our adversaries are producing offensive threats in the tens of thousands per year.

HRL Laboratories

Electrical Test Engineer, Advanced Sensors

In-house build: design and build the Q-switched Er:glass laser, covering Er/Yb glass selection, pump-diode and thermal design, passive (Co:spinel) or active Q-switching, cavity and output coupler, fluence versus laser-damage budget, and run it from first light to a qualified, producible unit. Near term (buy): survey and downselect off-the-shelf Er:glass microchip modules, seeded MOPA transmitters, and seed lasers from the global supply base, where expediency and cost lead; own the vendor technical relationships.

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 the defense legacy, with supply-chain security engineered in from day one. A perfect optical system images a point as a point; your job is to hold the seeker as close to that as physics allows in excess of Mach 3 aerothermal loads, vibration, and shock, and to prove it with an error budget that closes.
