Photonics Process Integration Expert

About OneTouch Technology OneTouch Technology is an innovative photonics company developing next generation optical components for high-performance communication systems for datacom and telecom applications. We combine advanced engineering, precision manufacturing, and strong supplier partnerships to bring cutting-edge solutions to market. Are you passionate about pushing boundaries? Do you thrive in an environment that encourages curiosity and creativity? Join our team. From silicon photonics experts to industry professionals, we're building a community that thrives on intellectual curiosity and relentless pursuit of excellence. Position: Design Engineer, Optical Circuit Switching We are looking for a design engineer to lead the application of our integrated photonics platform to high-speed optical circuit switching. This is a lead role spanning photonics design, electronics design, and system-level design. You will own the switching demonstrator effort and grow it from prototype towards a product, working closely with the core team that drives our technology strategy from Belgium. Our proprietary Heterogeneous Integrated Silicon Photonics (HISP) platform sits at the core of this work. HISP integrates thin-film lithium niobate (TFLN) heterogeneously with silicon photonics, and we have demonstrated its performance in prototypes. This role extends that proven advantage to high-speed switching applications.

Key Responsibilities
Market and Application Understanding
• Learn what the switching market demands, which architectures that demand is linked to, and how our technology can improve on serving those needs.
• Interface with business development to translate market needs into technical requirements and steer the evolution of the HISP platform, so it stays compatible with those requirements. Architecture and Circuit Design
• Innovate and propose new optical circuit switches and switch architectures, and the control circuits that support them, to address current bottlenecks in high-speed switching.
• Develop a system-level understanding of fast optical switching, including switching speed, insertion loss, crosstalk, and scalability trade-offs.
• Design and analyse control-loop strategies for fast, stable switching, including bias control and calibration schemes. Prototyping and Demonstration
• Design the PIC optical circuits in our HISP technology required for switchingdemonstrators.
• Design and specify the surrounding high-speed control electronics for driving and stabilising the switch.
• Build prototypes and demonstrators, validate their performance, and present results to internal teams and external partners.
• Document designs, results, and performance trends, and feed insights back into platform development. Qualifications
• Master's degree or above in Photonics, Electrical Engineering, Physics, or equivalent experience.
• At least 3 years of related working experience in photonics or high-speed integrated systems.
• Experience with silicon photonics platforms (SOI, SiN) and PIC design.
• Proficiency in photonic and waveguide simulation and integrated-circuit layout.
• Understanding of high-speed electronics and control-loop and feedback theory for fast switching.
• Ability to work independently in a fast-moving R&D environment, and to work across the optical, electronic, and system domains.
• Ability to communicate in English, both written and spoken.
• Advantageous: experience with optical switching architectures, RF and microwave design, or system-level modelling of communication or switching networks.

What We Offer
• A leading role in defining a new application domain for a differentiated photonics platform.
• The freedom to shape architecture and technology direction from the ground up, working closely with business development on market direction.
• Access to advanced design, prototyping, and testing facilities.
• The opportunity to grow with a fast-scaling deep tech company.
• Close collaboration with an experienced international R&D team.
