Senior Optical Engineer Coherent EO Seeker Systems

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. Furientis was started to help solve this problem- introducing a new class of cost-effective, high production rate, interceptor missiles. We're seeking motivated individuals who internalize this problem and are eager to apply their past experience in similar industries (aerospace, defense, automotive/racing, robotics) and out of the box thinking to solve this problem for the US and its allies.

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.

You own the seeker's coherent channel from source to signal: laser illumination, coherent detection, and the active EO path that runs alongside the passive LWIR train. The architecture, the link budget, the receiver, and the bench demonstrations that become flight hardware are yours. You are also the laser transmitters' customer and integrator: you own what they must deliver, namely the transmitter specification, the channel-level proof that bought or built lasers close your link budget, and their integration into the channel.

Designing and building the lasers themselves belongs to the Laser Engineer; judging them, specifying them, and making the channel perform with them belongs to you. Shared apertures and anything the passive train touches carry the opto-mechanical engineer's sign-off; the coherent channel's performance carries yours.

• Architect active EO channels: source, modulation, transmit path, receiver, and detection scheme.

• Own the link budget end to end and defend it against measured data.

• 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). The Laser Engineer designs to it; you defend it.

• Laser source selection and qualification, near term, off-the-shelf transmitters from wherever expediency and cost win, plus modulators and detectors, and hold the technical vendor relationships for them.

• Characterize transmitters as channel components and own their acceptance at channel level: measured energy, jitter, beam quality, and coherence over temperature and life, proving the link closes with real hardware rather than datasheets.

• Design and build the coherent receiver: optical, electrical,…
