About Ommo

Ommo is the pioneer of permanent magnet–based 3D tracking technology, building a next-generation tracking platform based on magnetic sensing. Our technology enables ultra-precise, real-time 6DOF tracking for millimeter-scale wireless sensors, up to 1,000 times per second with accuracy down to 0.1mm, without line-of-sight constraints. We partner 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. Our 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.

We're 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 test fixture & software installation, management & maintenance
• Onsite low volume production oversight & support
• Define test system requirements & perform performance qualification (PQ)
• 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
