Lead Mechanical Engineer

• Tampere, Finland
• Hybrid
• Permanent

We build precision automation for the supply chains of the world’s largest smart device makers: a measurement instrument placed exactly where it needs to be relative to the device under test, every time. Today that means tens of micrometres. With co-packaged optics, it means sub-micron. We’re looking for someone to own that mechanics, from concept to accepted machine.

The role cuts both ways, and that’s the point. You define the architecture, accuracy targets and acceptance criteria. Our manufacturing partner does the detailed design and builds the machine.

Steering that work is the heart of the role. You set clear requirements, review the partner’s design, catch what won’t reach the accuracy or can’t be made, and accept the machine only when it does what it should. That takes understanding the design at detail level, and when schedule or quality demands it, you open SolidWorks and design it yourself.

A chief designer who still remembers how a drawing is made.

What you will do

• Define machine architecture and specification: precision motion axes, instrument carriers and DUT fixtures
• Own accuracy end to end: error budgets, stiffness, thermal effects and repeatability
• Solve alignment between instrument and DUT: datums, kinematic fixturing, sensor- or vision-based
• Develop calibration and compensation with the software team, and verify accuracy by measuring
• Lead specs, design reviews and technical acceptance with our manufacturing partner
• Develop design standards and mentor others as mechanical lead

What we are looking for

• You’ve designed precision machines and mechanisms and taken them to production. We don’t count years, but this isn’t your first one.
• Precision parts and tolerancing down to the detail: GD&T, fits, actuators and sensors, and a clear sense of what manufacturing technologies can and can’t do
• Confidence to own decisions and steer a subcontractor, and the sense to ask before something goes wrong

It’s a plus if you have experience in:

• Sub-micron alignment: photonics, fibre or lens
• Production test or assembly equipment for smart devices
• Motion control basics (Beckhoff, Zaber)
• SolidWorks and PDM
• Shop floor work

What we offer

Real machines for the world’s biggest customers. Teams in Europe, the US and Asia. A small crew where decisions happen without a committee. Modern tools, and a licence to use AI daily.

Work where you work best. The machines live in Tampere, though, so fully remote isn’t an option.
