Engineer responsible for testing and characterizing silicon photonics optical circuit switches prototypes to validate architectural assumptions and correlate measurements with models.
О компании
- builds silicon photonic chips that steer and switch light at high speed. They power next generation, chip-scale FMCW LiDAR for robotics and autonomy, and optical circuit switches (OCS) for AI data centers. Based in NYC, we’re a hands-on team designing, building, and deploying frontier hardware to solve problems that matter, from how machines see to how AI scales.
- We build frontier hardware & software from our lab and office in Midtown Manhattan, where optical tables, lab benches and electronics sit alongside traditional office space. Our work is hands-on and primarily in person, but we don’t run on a rigid 9-to-5. We partner with customers across time zones, so some calls start early or run late, and we adjust schedules around them. We run a high-trust, high-accountability environment: you’ll own meaningful work, move quickly and often wear more than one hat. Voyant provides catered lunch every day at HQ, and we’re a diverse group of food lovers from around the world who enjoy sharing food, culture and technical ideas around the lunch table.
Обязанности
- We're looking for a Silicon Photonics Systems Test Engineer to join our Systems Team, reporting to the System Integration Lead. You'll be one of the first hands-on engineers on the OCS program, taking it from early technical derisk through proof of concept. Our architecture and models are well developed; your job is to put them to the test. You'll stand up the first OCS test benches, characterize early chips and prototypes, find where hardware and models disagree, and turn those findings into decisions.
- Plan and run rapid derisk experiments on early SiPh test chips and subsystems to validate key architectural assumptions.
- Characterize optical performance across switch paths, including insertion loss, crosstalk, extinction ratio, polarization and wavelength dependence, and switching time.
- Correlate measurements against device, circuit, and system models, and feed discrepancies back to design and modeling with clear physical explanations.
- Identify and measure the indicators that predict how performance will scale with port count, such as per-element variation, neighbor crosstalk, and calibration effort per port.
- Design, build, and automate OCS test benches from the ground up, with test approaches that can scale as port counts grow.
- Generate clear test reports and well-formed hypotheses that drive design decisions and inform specification limits.
- Collaborate closely with photonics design, modeling, controls, electronics, and firmware engineers, and with peers on our LiDAR program.
- Move fluidly between quick-turn exploratory experiments and disciplined, repeatable characterization.
Требования
- BS in Electrical Engineering, Physics, Optics, or a related field (MS or PhD a plus).
- 4+ years of hands-on experience in photonic or optical test, characterization, or early-stage technology derisking, though we're open to exceptional candidates at other experience levels who show strong potential and the right attitude.
- Hands-on experience with optical lab equipment (tunable lasers, optical power meters, optical spectrum analyzers, polarization controllers) and fiber handling and coupling, plus standard electrical equipment.
- Demonstrated experience automating test equipment and analyzing large datasets.
- Proficiency in Python for test automation and data analysis.
- Comfort working closely with models: understanding the assumptions behind a loss budget or circuit simulation, designing experiments to test them, and explaining discrepancies in physical terms.
- Strong systems-level thinking and the ability to apply physics and engineering fundamentals to debug complex, ambiguous problems.
- Excellent written and verbal communication skills, able to turn raw data into clear reports and actionable hypotheses.
- A self-starter who thrives with minimal formal process, and is comfortable defining structure where it doesn't yet exist.
- Must be able to work on-site.
Будет плюсом
- Experience testing silicon photonic integrated circuits, optical switches, or datacom/telecom optical modules.
- Familiarity with photonic simulation tools (e.g., Lumerical or similar).
- Experience with wafer- or die-level probing and high-channel-count test setups.
- Experience automating motorized stages or fiber alignment systems.
