Q.ANT is building photonic processing systems that compute with light – delivering a scalable, energy-efficient alternative to transistor-based architectures for next-generation AI and HPC applications. Turning breakthrough technology into real products requires more than invention. It requires the precision to connect worlds that rarely meet: photonics, electronics, and advanced packaging working as one. Hybrid integration is where that convergence happens. As our **Senior Hybrid Integration Engineer (m/f/d)**, your mission is to drive the integration of photodiodes and lasers into photonic integrated circuits (PICs) – from first concept through full validation. You will support fully packaged PICs with integrated components and contribute directly to shaping Q.ANT's technology roadmap. Through hands-on system bring-up, cross-functional collaboration, and close work with external partners, you translate cutting-edge opto-electronic designs into functioning, characterized assemblies that meet performance targets. #### Your profile - Ph.D. in Electrical Engineering, Photonics, or a closely related field – or a Master's degree with at least 3 years of directly relevant industry or research experience. - Deep technical understanding of photodiode and laser physics, TIA and driver design and characterization, and hybrid integration approaches. - Proven hands-on experience with PIC testing, optical alignment, and system bring-up in a lab or production environment. - Familiarity with photonic integration platforms such as LNOI, InP, or SiPh is a strong plus. - Ability to balance complex electrical and optical trade-offs (responsivity, bandwidth, noise) and make well-reasoned design decisions independently. - Fluent in English, German is a plus. **Your responsibilities** - Lead photodiode and laser integration projects on PICs across the full workflow: design, build, characterization, and validation. - Perform hands-on PIC testing, optical alignment, and system bring-up, including signal readout and performance evaluation. - Collaborate with photonics, electronics, and packaging teams; coordinate suppliers, service providers, and research partners. - Ensure configuration control of process flows and maintain clear decision and action logs. - Introduce automation strategies for characterization and propose new process trials based on results. - Optimize integration yield and throughput; track KPIs including assembly yield, responsivity, TIA SNR, bandwidth, schedule adherence, cost per channel, and risks mitigated. #### Why us? - We hire for attitude and train for skills. - We encourage self responsibility and accelerate professional development. - We move fast and encourage experimentation. - You have the opportunity to be part of developing breakthrough photonic computing technology and have a lasting impact on the future of computing. - You can be part of a passionate international, highly skilled cross functional team. - You will have access to the founders of the company. ## How to apply Apply on the job page, https://germanydevjobs.com/jobs/q-ant-senior-hybrid-integration-engineer-m-f-d-oq1js5s: its Apply button opens the employer's own application page. ## More jobs from Q.ANT - [Senior Photonic Engineer – Electro-Optic Modulator Design (TFLN) (m/f/d)](https://germanydevjobs.com/jobs/q-ant-senior-photonic-engineer-electro-optic-modulator-design-tfln-rlqotdl): Q.ANT, Stuttgart, Germany.
