Mechanical Engineer

K2 Photonics is building the next generation femtosecond laser platform for precision sensing and timing applications. Our technology enables real-time, highly sensitive quantification of gases and material properties - bringing lab-grade spectroscopy to the real world.

As a Mechanical Engineer, you will work on the mechanical and sys tem-level design of our platform, driving it from late prototype stage through to robust, field-deployable, production-ready systems. This role requires hands-on mechanical design skills to develop rugged solutions for operation in harsh environments, with a clear path to production, and field qualification. The role is ideal for someone who thrives on mechanical challenges where every design decision di rectly impacts optical system performance.

• Design and model mechanical components and assemblies using CAD software.
• Own the mechanical realization of system integration considering tolerances, requirements on interfaces and spatial constraints.
• Develop rugged, compact, and serviceable enclosures for field-deployable systems.
• Ensure component manufacturability, serviceability, and integration readiness.
• Design and execute test plans for mechanical, thermal, and vibration robustness.
• Analyze failure modes and implement design improvements to enhance reliability and lifetime.

• Proven proficiency with 3D CAD software and PDM (Solid Works preferred).
• Proven experience with designing mechanical systems around optical assemblies.
• Experience working in a multidisciplinary R&D or product development environment.
• More than 3 years of experience in a hardware related role.
• Ability to translate high-level system requirements into mechanical design.
• Proactive and detail-oriented mindset.
• Fluency in English (German is a plus).
