Senior Mechanical Engineer

Wingtra AG; Zürich; On-site; CHF 120,000 - 190,000; Full time

Job summary

Wingtra AG, a robotics scaleup based in Zürich, seeks a hands-on Mechanical Design Engineer to drive parts from concept through series production. You will contribute to CAD models, DFX, and part qualification, collaborating with electronics, suppliers and production teams.

You’ll design lightweight, manufacturable components, select materials, and influence tooling, tolerances and process flows to ensure a robust production line and full product file ready for ramp-up.

Qualifications

• Several years experience taking mechanical products from prototype to series production.
• Strong CAD skills (SolidWorks/PDM) and precision tolerance analysis.
• Experience with injection molding and additive manufacturing.
• Hands-on prototyping with disciplined documentation.
• AI-assisted design exploration and data analysis experience is a plus.
• Curious, flexible, collaborative with drive to build great things.

Responsibilities

• Take a new aircraft from concept to series production.
• Design and iterate lightweight parts.
• Choose materials and processes with care.
• Own DFX: manufacturing, assembly, cost and serviceability.
• Work hand in hand with suppliers on tooling and part iterations.
• Own qualification with production materials and processes.
• Deliver the production-ready product file: CAD, drawings, BOMs, specs.
• Hand over a running line after qualification gates and ramp-up.

Job description

Join the Wingtra team and become part of this venture-backed robotics scaleup with a global and international team of 125+ dedicated Wingtranauts who want to see their actions have a positive and lasting impact on the world. Founded more than 8 years ago at ETH Zurich, Europe’s leading robotics university, our goal is to build the best aerial robots to digitize the world at the push of a button and set the basis for faster and better decisions. Wingtra provides efficient and reliable data solutions to a variety of industries ranging from mining, construction and agriculture to humanitarian organizations, environmentalists and wildlife monitoring groups.

We are reaching for the stars and together we might just get there. Open communication, asking hard questions and valuing diverse viewpoints are but a few things that will help us achieve our goals. Above all we will never stop learning and striving to help each other reach our maximum potential.

Help us take Wingtra’s new product platforms from fast prototypes to reliable series production. Embedded in the engineering team, you own mechanical design, qualification and industrialization through initial ramp-up. Together we deliver a qualified product, a complete product file and a working production line. We are early adopters of AI and actively build agentic workflows across engineering, from design and test planning to execution and analysis.

Responsibilities

• Take a new aircraft from concept to series production. You work in a small team with electronics designers and test engineers. You get direct feedback from prototypes, flight tests and production builds.

• Design and iterate lightweight parts. You design, build and test parts and assemblies, then improve them until they are ready for production.

• Choose materials and processes with care. You balance performance, volumes, unit cost, tooling investment and lead times.

• Own DFX. You design for manufacturing, assembly, quality, cost and serviceability, and you settle tolerances, interfaces and process constraints early.

• Work hand in hand with suppliers. You partner with sourcing on technical feasibility, tooling and part iterations.

• Own qualification. You qualify parts with the intended production materials and processes, and you agree product-specific acceptance criteria with the test engineers.

• Deliver the production-ready product file. CAD, 2D drawings, tolerances, BOMs, material and process specifications and acceptance criteria.

• Hand over a running line. Once the qualification gates have passed and ramp-up is complete, you hand the line and the product file to Production and Production Engineering.

Requirements

• You have several years of experience taking mechanical products through the full lifecycle: prototype, series production and quality monitoring at the customer. Ideally on structurally critical products at volumes of hundreds to a few thousand units.

• You are strong in CAD (Solidworks/PDM preferred), tolerance analysis and material selection.

• You have practical experience with injection molding as well as additive manufacturing for functional plastic parts.

• You prototype fast and pragmatically, then qualify and document with discipline.

• You like hands-on work: builds, testing and working with suppliers.

• You use AI for design exploration, qualification planning and data analysis. You check its output, share new workflows and keep raising the team’s bar.

• You are curious, flexible and collaborative, with a real drive to build the next great thing.

If you enjoy teamwork more than being the individual superhero, and if you thrive in a feedback-driven culture and an exciting, unconventional yet structured and progressive start-up environment, we would love to hear from you.
