Job description :

Location : 42 Cours Pierre Vasseur, 91120 PALAISEAU, France

Start date: March 2026

Contract: Full-time (CDI)

We are looking for a Detector Department R&D Manager to lead the development of one of our most critical components: high-speed photodetectors. You will coordinate closely with the other departments to align detector development with the broader technology roadmap.

You will report to CTO-level and act as the technical lead and architect for our detector technology, driving developments from design to characterization while ensuring seamless synchronization with our in-house fabrication department.

This is a strategic role for a "builder." You will start by managing a small nucleus of engineers (2-3 people) with the specific mission to structure, recruit, and scale the team to ~5 experts within the next 12 months.

Key Responsibilities

1. Team Leadership & People Management: Manage the daily operations of the team. Conduct performance reviews, set individual objectives, ensure skill development, and maintain a high level of engagement and well-being within the department.

• Build the Team: Define needs, interview, and onboard new talents to grow the department from 2 to 5+ people by the end of next year.

• Project Management: Organize workflows, set timelines, and ensure delivery of milestones for the detector roadmap.

2. R&D Strategy & Technical Execution

• III-V on Silicon: Lead the full internal development cycle (Design, Layout, Characterization) of high-performance III-V photodetectors on Silicon.

• Other Detector Support: Support the integration strategy for externally fabricated detectors (Internal Layout & Characterization) in coordination with external partners.

• Simulation & Design: Drive the design flow using Lumerical and Python-based simulation tools. Ensure robust layout generation.

• Data-Driven Development: Supervise the characterization protocols, data analysis and test bench automation to close the designed to fabricated devices correlation loop.

Profile & Requirements

We are looking for a Senior profile (>8 years of experience) with a strong industrial mindset. While a PhD is valued, it is not mandatory if compensated by significant industrial R&D experience.

Hard Skills:

• Semiconductor Physics: Deep understanding of optoelectronic devices, specifically Photodetectors.

• Simulation & Layout: Proficient with Lumerical (Optical and electrical modules) and usual layout tools. Experience with Cadence is a plus.

• Programming: Strong understanding command of Python is essential (used for e.g. simulation, layout, data analysis).

Soft Skills:

• Leadership: Proven experience in people management. You know how to align a team around a common goal.

• Industrial Rigor: You know how to transition from "lab prototype" to "reliable component."

• Agility: You are comfortable in a startup environment where priorities can shift, and problem-solving requires creativity.

• Communication: Fluent in English (working language).

You don’t check all the boxes? Please submit an application anyway, we’ll be happy to consider it.

Benefits

• Comprehensive Health Care Plan

• Life Insurance

• Meal vouchers

• Commuter Benefit (50% refund of public transportation pass)

• Generous Time Off (Vacation, Sick & Public Holidays)

• Flexible, hybrid workplace model

• Stock Option Plan

Actual pay will be based on several factors including work experience, location and education.

We strongly value a heterogeneous environment to bring perspective, experience and skills to the table, leading to innovation and creativity.
