Senior Prototype & Manufacturing Engineer

We are looking for a Senior Prototype & Manufacturing Engineer to strengthen our Engineering team. Join Optics11 and help turn innovative designs into manufacturable products.

At Optics11, we develop cutting-edge fiber-optic sensing solutions that make critical infrastructure and underwater security systems smarter, safer, and more reliable.

In this role, you will play a key part in transforming engineering designs into robust, manufacturable products. You will take ownership of prototype realization and Design for Manufacturing activities, ensuring products can be built, assembled, integrated, tested, and scaled efficiently. Working closely with multidisciplinary engineering teams, suppliers, manufacturing partners, and internal stakeholders, you will help bridge the gap between product development and successful product realization.

What You'll Do

•

Take ownership of prototype realization and Design for Manufacturing (DfM) activities within multidisciplinary product development projects.

•

Support the transition from engineering designs to prototype, pilot production, and manufacturing-ready solutions.

•

Plan, coordinate, and support prototype assembly, integration, and build activities, ensuring products can be built and tested efficiently.

•

Develop and maintain assembly procedures, work instructions, manufacturing documentation, and prototype build records.

•

Evaluate product designs from a Design for Manufacturing (DfM), Design for Assembly (DfA), and Design for Test (DfT) .perspective, providing recommendations to improve manufacturability and product robustness.

•

Collaborate closely with engineering teams, suppliers, manufacturing partners, and internal stakeholders to resolve assembly, integration, and production challenges.

•

Participate in prototype testing and validation activities, capturing build findings and lessons learned to support future product iterations.

•

Apply structured problem-solving methodologies to investigate manufacturing, assembly, and integration issues, supporting root cause analysis and corrective actions.

•

Identify manufacturing risks early and drive mitigation actions to improve product quality, reliability, and production readiness.

•

Provide technical input on producibility, tolerances, assembly methods, tooling requirements, and manufacturing feasibility during design reviews and development activities.

•

Contribute to continuous improvement initiatives by enhancing manufacturing methods, assembly processes, tooling approaches, and development workflows while sharing knowledge and best practices across the organization.

Why Join Us?

•

Join one of Europe’s most promising deep-tech scale-ups.

•

Shape the future of a rapidly growing multidisciplinary R&D organization.

•

Competitive salary and benefits package.
