Mechanical Engineer II

Internship Additive Manufacturing for deep sea applications

As an Additive Manufacturing Intern, you will explore and evaluate a range of additive manufacturing techniques and validate their performance under the extreme pressures of the deep sea. You will develop automated test setups for pressure testing, and you will design, manufacture, and validate prototypes for new subsystems of our next-generation underwater drone. Your internship centers on demonstrating that additive manufacturing can reliably withstand harsh deep-sea environments over long periods. It is not only supported by theory, but by rigorous physical testing and real-world prototypes.

Den Haag

Company Summary

Lobster Robotics engineers autonomous underwater vehicles for precision seabed mapping. Our technology delivers millimetre-scale data for offshore energy and security of critical underwater infrastructure. In the past year, we expanded to 19 people and shifted from prototype to operational deployment. We combine research depth with field pragmatism, building systems that work in the real world. Backed by strong traction from the Dutch Navy and increasing involvement in NATO trials, we’re entering a phase of rapid scaling. We are looking for experienced engineers and passionate interns who can independently shape and deliver the next generation of underwater perception and mapping technology.


What You’ll Do

  • Research and develop innovative pressure housings for sensors.

  • Analyze failure points, deformation modes, and mechanical tolerances in detail.

  • Design, prototype, and test components produced via various additive manufacturing technologies (SLS, SLA, MJF), including their interactions with fluids and integration of O-ring seals.

  • Collaborate with our manufacturing team to ensure your designs are both high-performing and feasible to produce.


What We’re Looking For

  • Equipped with a strong mechanical engineering background, ideally with a focus on structural mechanics, materials science, or mechanical design.

  • Experienced with CAD tools (e.g., Onshape, SolidWorks, Fusion 360) and familiar with FEA software.

  • Detail-oriented and driven to understand why something failed and how to make it better the next time.

  • Bonus: Familiar with underwater sealing, corrosion, fatigue, or additive manufacturing.


Requirements

  • Studied mechanical engineering or similar on HBO of WO level

  • Excellent communication skills in English or Dutch

  • Build stuff and designed with CAD

  • Independent and practical, and detailed-oriented.

  • Full time availability for at least 3 months.


This is what we expect you to bring to the table

You have extensive practical experience designing and building projects outside your academic studies. We seek a candidate with a strong portfolio of projects, prepared to showcase examples during the interview and provide detailed explanations of their functionality, design decisions, challenges faced, and solutions implemented. Your past projects demonstrate reliability and innovative, yet simple designs. You excel at working independently, proactively seek structured feedback, and prioritize collaboration and clear communication.


Our values

We value clarity, ingenuity, and safety. If something goes wrong, we expect clear communication, a smart workaround, and a safe process. That’s how we operate.

We also care about impact. Our drones reduce CO₂ emissions by replacing large survey ships. They help protect marine ecosystems and support the safety of critical infrastructure.


What we offer you

  • End-to-end ownership of technically complex projects and from concept to deployment

  • A role in shaping our next-gen underwater drones and autonomy stack

  • Friendly team of colleagues who are happy to help when required

  • A workplace where planning is taken seriously, and your time is respected

  • Internship compensation of €500 per month
