Semiconductor Laser Design Engineer – III-V / InP (Junior / Senior)
Wolveshill Consulting Ltd.
Full-time | United Kingdom | Work From Home
Salary: £55,000–£100,000 per annum, depending on experience
3 positions available
Company Description
Wolveshill Consulting Ltd. (WHC) is a UK-based industrial technology company working across semiconductor technologies, IoT, industrial digitalisation and connected systems. As part of the continued development of our semiconductor business, we are expanding our UK-based technical team and are looking for three Semiconductor Laser Design Engineers, across Junior and Senior levels, with expertise in III-V compound semiconductors and InP-based optoelectronic devices.
This is an opportunity to join a growing semiconductor venture at an early stage, contribute to the development of next-generation photonic technologies, and participate in our Company Share Scheme.
Role Responsibilities
- Lead the device design, simulation optimisation and process development of InP chips, including optoelectronic performance modelling, structural design and parameter validation.
- Design and develop high-speed integrated modulators and semiconductor lasers, addressing key technical challenges including high-frequency signal integrity, thermal management and chip-package co-design.
- Work closely with process engineering teams to develop wafer fabrication and tape-out plans, lead chip performance testing and failure analysis, and optimise product yield and reliability.
- Monitor and evaluate emerging technologies, including Co-Packaged Optics (CPO), coherent optical modules and related technologies, and contribute to the technical roadmap for next-generation products.
- Prepare technical documentation, patents and standardisation proposals to support product development and commercialisation.
- Lead reverse engineering and benchmark testing of competitor chips, using electrical and optical parameter analysis, materials characterisation and other analytical techniques to identify key design characteristics and support internal design iteration.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Qualifications & Experience
Education
- PhD or equivalent professional experience in Microelectronics, Optoelectronic Engineering, Semiconductor Physics, Photonics, Electrical/Electronic Engineering, or a closely related discipline.
Experience
- Relevant experience in the design of III-V compound semiconductor optoelectronic devices, including EML, DFB, APD or related devices.
- For Senior-level candidates, 5+ years of experience in III-V compound semiconductor optoelectronic device design is preferred.
- Experience leading the development and successful production of 100G or higher-speed products is highly desirable, particularly for Senior-level candidates.
Technical Skills
- Strong proficiency with high-frequency electromagnetic and photonic simulation tools such as Lumerical and COMSOL, and semiconductor device simulation tools such as Silvaco.
- Strong understanding of key performance metrics for high-speed optical chips, including bandwidth, TDECQ and BER, as well as their testing methodologies and optimisation approaches.
- Good understanding of optical communication systems, including PAM4 modulation and DSP co-design. Experience in chip-to-module co-development is highly desirable.
- Familiarity with optoelectronic device reverse-engineering and analysis techniques, including SEM/TEM cross-sectional analysis, EBIC carrier imaging and spectral response analysis, with the ability to combine analytical results with simulation tools to develop competitor device models.
