About Quandela:
Quandela is a European deeptech scale-up building modular, scalable and energy-efficient photonic quantum computers.
With more than 140 people, we develop our own hardware technologies — from single-photon sources to photonic integrated circuits (PICs) — and make them accessible via cloud and on-premise systems.
At the core of our processors are Photonic Integrated Circuits (PICs): compact optical chips that route and manipulate single photons to perform quantum operations at scale.
About this position:
You will join the Integrated Photonics team in Massy, working at the interface between design, fabrication, and system integration.
As chip production increases, the team is transitioning from prototype-driven experimentation to structured batch qualification. We now receive larger volumes of photonic integrated circuits from semiconductor foundries and must evaluate them systematically before integration into increasingly complex quantum systems. This role is central to that transition.
We are open to junior and early-career profiles - (Master or PhD graduates) - who want to build strong laboratory expertise in integrated photonics characterization, as well as more experienced engineers who can progressively contribute to automation and structuring efforts.
Your responsibility will be to ensure reliable, repeatable and rigorous characterization of PIC devices. This includes hands-on laboratory work on recurring measurement tasks, with progressive exposure to automation and workflow improvements as you gain experience.
This is not a pure research role. It is an operational and scaling position within a high-tech hardware platform, with strong laboratory ownership at its core.
What will you do?
➡️ Characterize fabricated photonic chips
• Perform optical and electrical measurements on PICs at die level
> Measure transmission, losses, interferometric behavior, phase shifters, detectors, and related components
> Conduct cryogenic measurements when required
• Execute batch-level characterization with high measurement discipline and traceability
➡️ Operate and progressively improve qualification workflows
• Execute structured batch-level measurement protocols
• Apply defined go/no-go qualification criteria
• Ensure data acquisition quality, traceability, and clear documentation
• Contribute to statistical performance tracking and batch-level quality monitoring
• Develop Python scripts to automate and streamline measurement routines (depending on experience)
➡️ Collaborate across teams
• Compare measured data with simulation results and identify performance gaps
• Provide structured feedback to design teams and foundry partners
• Support device validation before packaging and system integration

How you'll grow?
0–3 months:
Operate under training on existing setups and take ownership of specific measurement benches. Execute reccuring characterization tasks with rigor and autonomy in the lab.
3–6 months:
Manage recurring characterization of production batches independently. Contribute to improving measurement efficiency and documentation.
6–12 months:
Participate in refining qualification criteria, statistical monitoring, and scalable measurement workflows as production volume increases.
Longer term:
Grow toward deeper technical ownership of characterization workflows and increased responsibility within the integrated photonics team as the platform scales.

What we’re looking for?
Must-have
• Degree in Photonics, Physics, Electrical Engineering or closely related field (Master’s or PhD)
• Hands on experience charactererizing integrated photonic components using lasers, fibers, alignement stages and powermeters
• Ability to operate autonomously in optical laboratory environments after training
• Strong experimental rigor and ability to analyze measurement data
• Scripting skills for data analysis or measurement automation (Python)
• Professional English
Important (can grow here)
• Experience comparing experimental results with simulation data
• Familiarity with high-speed measurements of electro-optic phase shifters
• Familiarity with cryogenic measurements
• Exposure to structured or batch-based testing workflows
• Basic understanding of fabrication constraints in integrated photonics
Bonus
• Wafer-level measurements
• Experience working with semiconductor foundries
• Statistical analysis applied to yield or performance monitoring
• Exposure to detector integration or advanced photonic subsystems
What matters most is laboratory rigor and reliability, enabling structured characterization that supports production-scale integration.
Salary range
Indicative gross annual salary:
• €45–50K — junior profile (Master’s graduate or early-career PhD, 0–2 years experience, strong lab foundations, able to execute structured PIC characterization after training)
• €53–58K — intermediate profile (2+ years experience after Master’s or PhD, autonomous in PIC characterization)
• €58–65K — experienced profile (3–5+ years PIC characterization experience, able to handle complex measurements and contribute to qualification structuring and yield improvement)
> We may also explore hiring a more senior characterization profile later in the year, to further support automation and qualification scaling efforts. If your experience exceeds the scope described above, we still encourage you to share your CV and start a conversation with us.
Perks: annual profit-sharing • company savings plan • 100% health coverage (Alan) • transport reimbursement or mobility bonus • Swile meal vouchers • Gymlib access
