Job Description

Job Description Tulip Tech designs and manufactures high-density lithium battery systems for drones and electric aircraft. Our silicon-anode technology extends flight times well beyond conventional packs. Every system is designed, built, tested, and assembled in-house in Den Bosch. Following a 2025 partnership with the Dutch Ministry of Defence, we are scaling from prototype development to volume production. The technology is proven. Our focus now is building it reliably, at scale, without losing the engineering quality that got us here. Designed, built, and proven in Europe. Why this role matters Our batteries fly. What keeps them in the air is a mechanical assembly that has to be light, strong, thermally sound, and manufacturable at volume. As our Mechanical Engineer, you own that chain end to end: from the first CAD model, through prototyping and validation, to production handover. There is no separate test team to hand off to and no decades of in-house mechanical standards to fall back on. You design it, build a prototype, and stress-test it until you know it survives heat, vibration, and assembly before it goes anywhere near an aircraft. As we industrialize, you also help define how mechanical design and validation work here. It is real ownership over a core part of the product. What You Will Achieve Battery enclosures and mechanical assemblies, designed in SolidWorks to be light, thermally efficient, and manufacturable at scale. Designs validated for structural integrity and environmental durability under real airborne conditions, using FEA and thermal analysis. Prototypes built and tested with CNC, 3D printing, and shop tools before anything moves to production. A measurable reduction in mechanical iteration time, through earlier prototyping and design-for-manufacture feedback to the engineering team. Repeatable mechanical design and validation practices the team can reuse as we scale from prototype to volume. Specifications, test results, and compliance documentation that hold up to certification review. Job Requirements Proven mechanical design experience in a real manufacturing or production environment, ideally around 2 - 7 years. Strong SolidWorks skills: assemblies, drawings, and BOM management. FEA and thermal analysis to validate designs under structural and thermal load. Working knowledge of manufacturing methods: CNC machining, injection molding, sheet metal, and extrusion. A hands-on mentality: you build and break things to prove they work, not just model them. The judgment to work from engineering knowledge and experience, not procedures alone, and to correct a design when it is wrong. Nice to have Thermofluid knowledge or experience with thermal management systems A background in battery, EV, drone, automotive, or aerospace hardware Experience taking a design from prototype through to volume production Why join A genuine core engineering challenge: you own the mechanical design of a product that flies, from CAD to production handover. Real ownership and influence over technical decisions in a flat, engineering-led organization. A clear mission: enabling electric flight and contributing to European defense capability. Salary between 3300,- and 5800,- 38 paid days off per year (25 vacation + 13 ADV via CAO Metaal & Techniek). 8% holiday allowance, travel reimbursement, pension via PMT, and daily lunch on-site. An international team of more than 10 nationalities, with regular team events.

Core Responsibilities

Design and validate lightweight, thermally efficient, manufacturable battery enclosures and mechanical assemblies, taking them from CAD through prototyping and testing to production handover. Establish repeatable mechanical design and validation practices, reduce iteration time, and prepare specifications, test results, and compliance documentation for certification review.

Requirements

Candidates should have approximately 2–7 years of mechanical design experience in manufacturing or production, strong SolidWorks skills, and experience with FEA, thermal analysis, and relevant manufacturing methods. The role also requires a hands-on approach to building and testing prototypes; battery, EV, drone, automotive, aerospace, or thermofluid experience is advantageous.
