Development engineer (m/w/d) (Ingenieur/in - Elektrotechnik)

Senior Electrical Engineer (m/f/d)

About Us
At betatron bio° we support our clients in developing sophisticated instruments and systems for the life science and diagnostics industries.

Our focus is on microfluidics, systems engineering, and AI - three disciplines we bring together into thoughtfully engineered and integrated systems, taking complex ideas from early concept through prototyping, validation, and pilot production.

To strategically expand our product and systems development in Münster, we are looking for a Senior Electrical Engineer (m/f/d) who will take ownership of the hardware and PCB design for complex measurement and control systems and see projects through from circuit design to final commissioning.

You will work in a highly specialized team with direct customer contact, international project assignments, and a short path from idea to implementation.
Design and develop PCB layouts for analytical instruments, medical-technology and diagnostic systems (analog, digital, mixed-signal) - from concept through to production-ready design
Hardware design including component selection, schematic capture, and design for manufacturability (DFM/DFT)
Develop and integrate firmware (embedded C/C++) for microcontroller-based measurement and control systems
Systematically test, debug, and commission electronic assemblies directly in the lab - hands-on and solution-oriented
System integration in close coordination with mechanical engineers, software developers, and customers
Technical documentation in line with regulatory requirements (IEC 60601, ISO 13485)
Help shape and continuously improve our development processes in a growing deep-tech startup
Must-haves

Bachelor’s degree in electrical engineering, mechatronics, or related technical field
At least 5+ years of professional experience in PCB design and hardware development - ideally in medtech, diagnostics, or industrial automation
Hands-on firmware development: embedded C/C++, microcontroller programming, interfaces (SPI, I2C, UART, USB)
Hands-on experience with test instruments such as oscilloscopes, signal generators, spectrum analyzers including structured test execution, documentation, and reporting.
Strong ability to collaborate with cross-functional teams and drive independent work.
Excellent written and verbal communication skills in English and in German.

Nice-to-haves

Experience with microfluidic systems, lab-on-chip, or MEMS
Knowledge of EMC-compliant design and signal integrity analysis
Experience with ISO 13485 / IEC 60601 or comparable regulatory frameworks
Knowledge of Python or MATLAB for data analysis and test automation

Real impact: You'll help shape our product architecture directly - your designs go into market-relevant life science devices and directly influence our customers' strategies.

Variety, not routine: Projects spanning multiple customers, applications (diagnostics, single-cell analysis, sequencing, lab automation), and development phases - no two days alike.

Top-tier team: Work alongside internationally experienced founders, AI engineers, and systems engineers.

Growth & responsibility: A clear development path in a fast-growing company - help shape our processes, methods, and team.

Flexibility & culture: Flexible working hours, short decision-making paths, and a collaborative culture (innovation, excellence, collaboration)

Attractive package: Competitive compensation and a modern workplace in the heart of Münster.

About betatron bio°
At betatron bio°, we believe that great engineering happens when deep technical expertise meets speed, curiosity, and practical execution.

We combine deep microfluidics expertise with systems engineering excellence and AI-powered development tools - for results that speak for themselves.

If you want to work on real-world engineering problems with real-world impact, rather than maintaining an established product for years, we would like to hear from you.
