Senior Integrated Photonics Packaging Engineer (RF) (m/f/d)
Q Ant Gmbh · Stuttgart

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

- 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

- **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
