About the role
- Develop and validate physiological sensing systems for acquiring and analyzing physiological signals in wearable health and wellness products
- Define hardware and software technical specifications and implement test and calibration protocols both internally and at manufacturer sites
- Ensure that the physiological sensors integrated in our products meet their specifications from prototype to mass production
- Build and validate hardware architectures optimized for low-noise, high-resolution time-series signal collection
- Plan and execute benchtop and on-body testing to evaluate system performance across various user populations
- Support validation and compliance efforts in collaboration with regulatory, research, and clinical teams
- Work cross-functionally to ensure end-to-end system performance and signal integrity
- Conduct rigorous testing and troubleshooting to ensure sensor performance across varying environmental and use-case conditions
- Collaborate closely with mechanical and electrical engineers to integrate sensors within constrained form factors and flexible layouts
- Partner with firmware and software teams to enable and refine features built on physiological data
- Work directly with sensor vendors to evaluate new components, optimize performance, and address integration challenges
- Travel occasionally to Finland and to global manufacturing or development sites as required (15%–20%)
Requirements
- Strong electrical engineering background and experience with the design and testing of low-noise analog or mixed-signal systems
- Strong understanding of time-series physiological signal acquisition, including best practices for minimizing noise and motion artifacts
- Familiarity with algorithmic methods for time-series signal modeling and calculating physiological metrics
- Simulation and modeling experience using tools like ANSYS, CST, or COMSOL
- Skilled in embedded software and data acquisition tools such as C/C++, Python, or similar
- Experience with data analysis and signal processing tools such as Python, MATLAB, or JMP
- Strong experimental and analytical skills with a methodical approach to isolating and debugging complex issues across hardware and algorithm domains
- Ability to work independently through ambiguity and rapidly iterate on early-stage concepts
- Driven by data and eager to understand root causes behind performance issues
- Effective communicator across disciplines, with the ability to clearly convey technical insights both in written and verbal form to technical and non-technical audiences
- Experience working in cross-functional teams spanning hardware, firmware, product, and research
- Contributed to project documentation, planning, and alignment with stakeholders
- Bachelor’s degree in electrical engineering, mechanical engineering, biomedical engineering, physics, or related field with 7+ years of relevant industry experience
- Master’s degree with 5+ years, or PhD with 2+ years of relevant industry experience
- Hands-on experience building and characterizing early-stage hardware systems
- Proficiency using various lab instrumentation tools such as digital multimeters, oscilloscopes, signal generators, spectrum analyzers, physiological simulators, power analyzers, and environmental chambers
