Job description

Our client is the pioneer of permanent magnet–based 3D tracking technology, building a next‑generation tracking platform based on magnetic sensing partnering with medical device OEMs and advanced technology companies developing surgical navigation, robotics, simulation, spatial intelligence, and human‑machine interface systems.

Research and testing are fundamental to how we develop our products. The technology - and the automated test systems, calibration methods, evaluation processes, and acceptance criteria behind it - is entirely proprietary and critical to delivering world‑class performance.

They are looking for a multidisciplinary Hardware Test Engineer to help execute and improve the systems that validate our technology every day. You'll perform R&D testing and investigations, analyze data, support production, and conduct failure analysis while also designing better fixtures, automating test processes, and improving documentation. This role is ideal for a hands‑on engineer who enjoys solving practical problems, building tools, and making complex systems more efficient.

Responsibilities

Testing & Execution

• Perform R&D tests & investigations (e.g. thermal characterization of sensors, interference & spacing limits, reliability studies) & write clear, decision‑ready test reports
• Perform R&D data analysis & review production data on an ongoing basis
• Onsite low volume production oversight & support
• Perform failure analysis on returned & defective products & feed findings back to the product development & engineering team

Fixturing & Mechanical

• Design, prototype, and improve R&D test fixtures and setups, including cabling, device mounting, ergonomics, and overall usability.
• Partner with the Mechanical Engineering team to design, prototype, and implement fixture improvements using CAD.
• Develop and maintain fixture documentation, including manuals and maintenance procedures.

Test Automation, Tooling & Data

• Build and improve automation and control systems for test rigs, lab monitoring, and data acquisition (e.g., environmental chamber automation, Raspberry Pi monitoring, USB instrument interfaces).
• Develop data analysis pipelines, scripts, and internal tooling that automate test processing and streamline validation workflows.

Documentation & Process

• Develop and maintain SOPs, work instructions, protocols, and documentation for tests, fixtures, and tooling.
• Define and standardize acceptance criteria and repeatable validation processes for new product bring‑up.

Qualifications

• B.S. in Mechanical, Mechatronics, Electrical, or Computer Engineering, or other related degree
• 1–3 years of hands‑on experience with testing, data collection, and analysis in an R&D, manufacturing, production, or laboratory environment. Relevant internships, co‑ops, research, and substantial academic projects may count toward this experience.
• Experience designing mechanical fixtures, parts or prototypes using CAD and rapid prototyping tools (3D printing, laser cutting, machining, soldering, etc.).
• Experience using Python (or a similar language) for automation and data analysis.
• Experience working with embedded systems, including Raspberry Pi or other microcontrollers.
• Good technical writing, able to turn technical work into clear procedures
• Good problem solving abilities, analytic troubleshooting experience a plus
• Capable of managing multiple projects at once

Nice to Haves

• Experience in a regulated or precision hardware environment (e.g., medical devices), including familiarity with ISO 9001 or ISO 13485 quality systems.
• A track record of building internal tooling, automation, or process improvements
• Experience with process verification & validation, or Test Method Validation
• Familiarity with GD&T & tolerance analysis
