Senior Integrated Photonics Packaging Engineer(RF)

Arbeitsbeschreibung - Senior Integrated Photonics Packaging Engineer(RF)

Your mission

The future of AI computing is light, not electrons.  
At Q.ANT, we are building photonic processing systems that compute with light - delivering a scalable, energy-efficient alternative to transistor based architectures for next-generation AI and high-performance computing. 
As Senior Integrated Photonics Packaging Engineer (m/f/d) in our PIC OPS team, you will drive the transition of Q.ANT’s photonic computing technology from R&D prototypes to miniaturized, high-performance photonic modules. Focusing on RF and electro-optical packaging, you will define, develop, and verify high-frequency packaging concepts that unite PICs, light sources, photodetectors, and analog circuitry. By managing global suppliers and innovating beyond existing design rules, you will create proprietary packaging architectures that form a core competitive differentiator for our technology. 


Your Impact & Responsibilities 


  • Define and own high-density electro-optical and RF packaging solutions, ensuring superior Signal Integrity (SI) and Power Integrity (PI) 
  • Lead supplier - driven R&D packaging projects from technical specification and contract negotiation through to final system integration and validation 
  • Perform electromagnetic modeling, co-simulation of package structures, and implementation of transmission line theory and EMC shielding techniques 
  • Drive Design for Manufacturability (DFM) and PCB/package layouting using advanced packaging materials and substrate technologies (HTCC, LTCC, HDI, Build-up) 
  • Execute thermal management strategies for high-power photonic and 
    high-frequency devices 
  • Establish quality assurance and verification protocols to achieve ≥95% 
    first-pass qualification on supplier-delivered modules 
  • Implement at least one new packaging material, process, or high-frequency architecture annually to build and protect proprietary Q.ANT IP 
  • Collaborate closely with internal R&D, systems, manufacturing, and test teams to align RF packaging solutions with overall system architecture




Your profile

  • M.Sc. or Ph.D. in Electrical Engineering, Photonics, Optoelectronics, Physics, or a related field; equivalent ndustry experience also considered 
  • 5+ years of hands-on experience in RF packaging, optoelectronic integration, or high-density interconnect technologies 
  • Proven track record of managing supplier-led R&D projects from requirement definition through to integration and validation 
  • Deep expertise in RF signal/power integrity, electromagnetic simulation tools, S-parameter measurements, and EMC shielding 
  • Solid background in semiconductor backend integration, thermal management, and advanced packaging substrates (HTCC, LTCC, HDI) 
  • Familiarity with CAD tools for electronic packaging, statistical process control (SPC), and industry standards (e.g., Telcordia, JEDEC) 
  • Solution-oriented mindset with high attention to detail, proactive ownership, strong self-leadership, and cross-functional communication skills 
  • Fluent in English; knowledge of German or another European language is a plus

Why us?

  • Work on the leading edge: Shape deep-tech evolution by developing novel high frequency packaging architectures that push the physical boundaries of AI computing.
  • Make impact at scale: Transition photonics computing from prototypes to scalable, high-yield mass production, directly accelerating our time-to-market. 
  • Broad decision-making authority: Enjoy wide autonomy to challenge existing design rules, define technical strategies, select suppliers, and propose new packaging technologies. 
  • Fast-track your growth: Solve complex high-frequency and electro-optical challenges with few industry precedents—every solution you build contributes to industry-defining IP. 
  • World-class team: Collaborate alongside a passionate, international team of experts in photonics, RF design, processor architecture, and AI systems. 
  • Direct access to leadership: Work directly with the Head of PIC, company founders, and an advisory board that has shaped the semiconductor industry. 

About us

Who we are and what we do
Q.ANT is a deep-tech scale-up developing photonic processing solutions that compute natively with light and deliver a scalable alternative to transistor-based systems. The analog co-processors are optimised for complex computations and enable energy-efficient performance for next-generation AI and HPC applications. In collaboration with the Institute for Microelectronics Stuttgart IMS CHIPS, Q.ANT operates its own pilot line for photonic chips, based on the material system Thin-Film Lithium Niobate TFLN. Q.ANT was founded by Michael Förtsch in 2018 and is headquartered in Stuttgart, Germany.
