Salience Labs provides photonic switch technology and optical networking solutions tailored for AI infrastructure. Backed by Oxford Science Enterprises.
About the role
You'll join a multi-disciplinary research team in the UK to lead the development of III-V active components for integration with silicon photonics. You will take devices from epitaxial stack and device design through fabrication with external partners, to characterisation, reliability and qualification. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- Proven track record of taking III-V devices from concept through design, fabrication and test, ideally including qualification
- Deep understanding of semiconductor laser and amplifier physics: optical gain, carrier dynamics, quantum-well design, noise, gain saturation and nonlinearities, thermal effects and polarisation dependence
- Hands-on knowledge of III-V epitaxy and fabrication processes (e.g. MOCVD/MBE growth, lithography, etching, passivation, metallisation, facet/AR coating), and experience working with external foundries
- Experience characterising amplifiers or lasers, including optical spectrum analysis, gain and noise measurement, wafer-level probing, temperature-controlled testing and test automation
- Experience with simulation and layout tools for photonic devices, such as Lumerical, Photon Design, Crosslight, RSoft, COMSOL, KLayout, L-Edit or Cadence Virtuoso
- Proven ability to lead technical projects across design, process, test and packaging functions, and experience mentoring or supervising engineers
