Datacom Infrastructure Engineer – Photonic Timing

Darwin Recruitment; Paris; Sur place; EUR 90 000 - 130 000; Plein temps

Résumé du poste

Darwin Recruitment is seeking an Expert Engineer in Datacom Infrastructure & Network Synchronization to help integrate next-generation photonic timing into high-speed datacom system.

You will work on ToR devices, SerDes/PHY architectures and clock distribution with a focus on ultra-low jitter and inter-component interoperability.

This is a deep-tech role at the intersection of photonics, networking and data-center architecture, offering strong ownership and impact.

Qualifications

• MSc or PhD in Telecommunications, Electrical Engineering, Network Engineering, Photonics, RF/Microwave Engineering or a related field.
• 5-10+ years of experience in datacom infrastructure, data center networking, switches, SerDes/PHY, synchronization systems, timing circuits or high-speed link design.
• Strong practical understanding of electronic oscillators, PLLs, retimers, CDRs and high-speed synchronization architectures.

Responsabilités

• Define and refine integration strategies for photonic timing solutions within switches, ToR devices and high-speed networking equipment.
• Design synchronization architectures where optical timing becomes a native reference across racks, switches and servers.
• Analyse SerDes and PHY requirements to ensure interoperability between photonic timing solutions and next-generation ASICs and switch fabrics.
• Develop optical and hybrid timing architectures supporting phase alignment and low-jitter operation.
• Evaluate the impact of synchronization architectures on BER, PAM4/NRZ signaling, jitter tolerance, eye diagrams and overall link stability.
• Assess interoperability with existing timing and synchronization standards, including Ethernet, PTP, SyncE and White Rabbit.
• Define potential migration paths from conventional electronic synchronization toward next-generation optical timing architectures.
• Contribute to product specifications, including interfaces, packaging and system integration constraints.
• Collaborate with hyperscalers, switch vendors and technology partners to validate solutions in data-center-like environments.
• Contribute to technology roadmaps and system-level architectural decisions.
