About the Job

Requirements

  • A B.S. in Optical Engineering, Photonics, Physics, Electrical Engineering, or a related field is required.
  • At least 5 years of hands-on optical engineering experience building and testing electro-optical systems, laser subassemblies, or precision optical instruments is required.
  • Strong benchtop optics craft, including alignment and metrology with lenses, mirrors, prisms, polarizers, filters, beam-steering devices, and fiber/free-space optics, is required.
  • Radiometry and optical link budget analysis from first principles are required.
  • Practical understanding of optical and detector noise sources, including background light, scatter, speckle, shot noise, dark current, and thermal/electronic noise, and how they limit sensitivity, is required.
  • Hands-on experience with avalanche photodiodes (APDs) and array detectors, including characterization, biasing/readout considerations, and signal-to-noise ratio tradeoffs, is required.
  • Working familiarity with pulsed and/or continuous-wave lasers and standard characterization measurements, including power/energy, pulse timing, beam profiling, divergence, and spectrum, is required.
  • Proficiency with Zemax (OpticStudio) for lens design, ray tracing, and optical layout is required.
  • Practical laser safety knowledge for everyday lab and range work, including hazard awareness, beam containment, and safe alignment, is required.
  • Proficiency in Python or a similar language for instrument interface and bench data analysis is required.
  • Must be a U.S. Person and eligible to access export-controlled information.

Responsibilities

  • Design, build, and align free-space and fiber-coupled benchtop optical setups using lenses, mirrors, prisms, beamsplitters, filters, and beam-steering elements.
  • Build and maintain radiometric and optical link budgets from source to detector, reconciling models against bench and field data.
  • Identify, measure, and mitigate optical and detector noise sources across the signal chain, including background radiance, stray light, scatter, speckle, shot noise, and readout noise.
  • Perform optical layout and basic lens design in Zemax for transmit, receive, and test-bench paths.
  • Characterize and integrate pulsed and continuous-wave laser sources into optical assemblies, measuring energy, pulse shape, beam quality, divergence, wavelength stability, and jitter over temperature.
  • Evaluate, characterize, and integrate APDs, PIN photodiodes, and array detectors, verifying responsivity, noise-equivalent power, bandwidth, linearity, and timing at the bench.
  • Partner with opto-mechanical and integration engineers to transition breadboard layouts into rugged brassboard and flight assemblies, supporting boresight, focus, and environmental tests.
  • Maintain safe, disciplined laser operations in the lab and on the test range through practical hazard controls, beam containment, and safe alignment habits.
  • Work with electronics and algorithm engineers to deliver calibrated optical measurements and realistic sensor error models into the seeker pipeline.

Desired Qualifications

  • An M.S. or Ph.D. in Optical Engineering, Photonics, Physics, Electrical Engineering, or a related field is preferred.
  • Hands-on experience with thermal imaging systems and infrared cameras (MWIR/LWIR) is desirable.
  • Hands-on experience with benchtop electronics, including detector biasing, transimpedance amplifiers, and laser trigger/drive interfaces, brassboard prototyping, or full OEM packaging of optical systems, is desirable.
  • Optical tolerancing and stray-light analysis using Zemax non-sequential, FRED, ASAP, or TracePro is desirable.
  • Optics lab automation experience, including scripting instrument control, automated alignment or test stages, and repeatable characterization pipelines, is desirable.
  • Experience with flight, airborne, or munition-class optical hardware built for shock, vibration, and thermal extremes is desirable.
  • Daily use of agentic coding tools such as Claude Code to accelerate modeling, analysis, and lab tooling is desirable.

About the Company

Furientis

Designs and manufactures high-rate interceptor missiles

Furientis is a defense technology company that designs and builds low-cost interceptor missiles with a focus on high-rate production. Its products, like the F1.0 Tactical Interceptor, are built from the ground up with vertically integrated subsystems—the seeker, control actuation, airframe, and solid rocket motor—using proprietary motor chemistry optimized for throughput. The missiles are designed for large-scale manufacturing, targeting production of about 1,000 units per factory per year and a 30-minute final assembly time per vehicle. The company emphasizes in-house manufacturing, rapid testing, and scalable operations, supported by a funded OTA contract with the U.S. government. Furientis aims to expand its production capabilities and flight-test operations, as shown by its seed funding round to hire more staff and increase testing and manufacturing capacity.
