Active PIC Designer

Senior/Principal PIC Design Engineer | Full-Time | Remote | up to £120k + Stock Options + Full Benefits
 
We’re seeking an expert in silicon photonics to design and optimize high-speed active devices used in next-generation photonic integrated circuits. This role offers the chance to work across design, simulation, and testing, while influencing the future of scalable, high-bandwidth photonic systems.

You’ll own the design of high-performance components such as MZMs, ring modulators, and photodiodes, collaborating with fab teams, process engineers, and packaging experts.
 
What You’ll Do

• Lead design and optimization of active photonic components including modulators and detectors.
• Perform full-cycle modelling, layout, and validation across multiple foundries.
• Work with test and characterization teams to analyse performance and refine designs.
• Contribute to documentation, IP development, and internal design standards.
• Mentor junior engineers and contribute to a collaborative technical culture.

 
What You Bring

• M.S. or Ph.D. in Photonics or related discipline, with 5+ years in silicon photonics design.
• Proven expertise in FDTD/MODE/DEVICE tools (Lumerical, Ansys, or Tidy3D).
• Experience with tapeouts across major SiPho foundries and understanding of process constraints.
• Strong Python/MATLAB skills for data analysis and yield improvement.
• Familiarity with co-design for ASIC interfaces and statistical modelling techniques.

 
What’s Offered

• up to £120k + Stock Options + Full Benefits
• Broad technical ownership and visibility
• Career growth in an elite, multidisciplinary team
• Opportunities to shape future product directions
