Senior SW Developer – GNSS Measurement Layer
Would you like to experience the thrill of working from the ground up on a first-generation product? Are you passionate about delivering the optimum design for multiple customers? Do you seek a position where your accomplishments matter? oneNav is building a next generation GNSS receiver that will shake up the industry. There will be opportunities to broaden your skill set in areas such as GNSS, various assemblers, RTL verification and firmware development. This position is based in Tampere, Finland with an established hybrid working environment.
Location: Tampere / Finland, remote/hybrid work
Employment type: Full-time
About The Role
We are looking for a Senior Software Developer to join our GNSS measurement layer team. This position focuses on high-quality software engineering and system integration, rather than algorithm research. Candidates with experience in DSP implementation of GNSS measurement layer or other measurement layers (cellular, Wi-Fi, Bluetooth) are strongly encouraged to apply.
Key Responsibilities
- Implement GNSS measurement-layer components in C
- Translate technical specifications into efficient, production-ready software that follows industry standards
- Apply best practices in modular design, unit testing, continuous integration, and version control
- Work closely with algorithm designers and system engineers to ensure robust integration and system-level performance
- Optimize software for performance, memory, and scalability across embedded and desktop environments
- Produce clear documentation of designs, workflows, and results to support reproducibility and team knowledge sharing
Required Qualifications
- 5+ years of experience in measurement-layer or DSP-focused software development
- Expert-level C programming, with commitment to clean, maintainable, and standards-compliant code
- Hands-on experience implementing DSP algorithms or working with measurement layers such as GNSS, cellular, Wi-Fi, Bluetooth or radar
- Familiarity with GNSS concepts (tracking, acquisition, interference mitigation) or strong ability to quickly learn domain-specific concepts
- Python proficiency for simulation, analysis, and tooling—comfortable with e.g. NumPy, SciPy, Matplotlib, and Jupyter
- Software engineering discipline – experience with SDLC, debugging tools, profilers, version control (Git), and CI/CD practices
- Excellent collaboration skills, with the ability to work effectively in cross-functional teams
- Ability to communicate effectively in English
- BSc and MSc, or PhD in EE, CS, Math, or equivalent foundational technical subject
Preferred Qualifications
- Embedded systems or real-time software development background
- Digital communications and signal processing theory knowledge
- Hardware-in-the-loop (HIL) testing or simulation frameworks experience
What We Offer
- A multicultural, international team and a collaborative, flat culture
- Project-based global work and exposure to cutting-edge L5-direct™ GNSS and AI technologies
- A true start-up environment with innovation time, fast decision-making, and direct access to leadership
- Career growth through regular development discussions, training, and high-visibility opportunities
- Hybrid work, flexible hours, and a remote-friendly, trust-based work style
- Competitive compensation with stock options to share in oneNav’s long-term success
- Startup-style perks, team events, and a friendly, supportive environment
