We bring diverse and pre qualified professional talent and businesses together to connect the right people with the right roles. By building specialized teams, we help individuals flourish in their careers and businesses succeed.
Dettagli di lavoro
We are hiring across four specialized profiles corresponding to our core functional units:
Measurement Chamber
Fluidics Component
Oximetry
HW Unit & Subsystem
Start Date: 16.09.2026 (Latest possible start date: 01.11.2026)
Duration: 1 Year (With option for extension)
Workplace: Rotkreuz, Switzerland
Workload: 100%
Home Office: Hybrid model (Minimum 51% onsite presence required)
Travel: 0–10%
Regardless of specialization, all candidates will drive core V&V operations across the project lifecycle:
Test Development & Execution: Design, prepare, and execute automated test suites, test cases, and test protocols for Verification and Validation (V&V) in strict compliance with medical device regulations (FDA/MDR).
Endurance & Reliability Testing: Develop and execute accelerated life testing (ALT), durability, and wear-and-tear tests to ensure long-term hardware reliability under real-world conditions.
Fixture Design & Automation: Build and assemble custom test setups, fluidic rigs, and test fixtures using CAD tools (e.g., SolidWorks), integrating sensors, pumps, and actuators.
Scripting & Data Analysis: Write automation scripts in Python to control test rigs, collect data, and analyze complex metrics using statistical methods.
Cross-Functional Collaboration: Lead root cause analysis (5 Whys, Fishbone diagrams) for defects, provide feedback for Design for Manufacturability/Assembly (DFM/DFA), and collaborate closely with software, firmware, and systems engineering teams.
Education: Degree (BSc, MSc, PhD, or HF Apprenticeship) in Mechanical Engineering, Electrical Engineering, Mechatronics, Biomedical Engineering, or a related field.
Professional Experience: 3 to 10+ years of hands-on experience in hardware testing, mechatronic unit verification, or product development.
Regulatory Knowledge: Proven track record working in a highly regulated medical device, In Vitro Diagnostics (IVD), or life sciences environment (FDA/MDR).
Tool & Software Proficiency: Hands-on experience with ALM tools (e.g., Codebeamer, PLM) for requirement traceability, alongside agile tools like Jira.
Language Skills: Professional fluency in English (written and spoken) is mandatory. Fluency or strong working knowledge of German is a distinct advantage.
Experience designing custom test fixtures using SolidWorks or similar CAD tools.
Practical knowledge in writing Python scripts for test bench automation and test rig control.
Demonstrated background in continuous improvement tools (5 Whys, Fishbone, DFM/DFA).
- Hands-on experience working in a BSL-2 laboratory environment.
Please indicate in your application which focus area(s) best align with your background:
1. Focus: Measurement Chamber
Evaluate electro-mechanical hardware (currents, voltages, clamping forces) and configure lab instrumentation (encoders, oscilloscopes).
Act as the primary point of contact for unit defects within Operations and the BSL-2 lab environment.
2. Focus: Fluidics Component
Apply fluid mechanics expertise to evaluate fluidic components (valves, connectors) and specialized measurement equipment.
Heavily plan and execute tightness, stress, and endurance testing on fluidic consumables.
3. Focus: Oximetry
Perform physical and optical testing on precision hardware, mechanical oscillators, and optics.
Evaluate microfluidic chips and safely handle biological sample preparation (e.g., whole blood handling and hematocrit adjustments) within a BSL-2 laboratory setting.
4. Focus: HW Unit & Subsystem Testing
Take ownership of Unit Specifications (USP) and lead Configuration & Item Management (tracking CIs and revision statuses).
Act as the primary technical bridge during the integration phase, managing critical hardware-software dependencies.
