Employment type: Full-time

• Build and maintain software that automates competitive receiver testing across jamming/spoofing waveforms and rolls results into standardized KPI tables.
• Build tools to mine and process huge log files to visualize trends and performance.
• Create internal dashboards, plots, and heatmaps that make receiver performance, test coverage, and countermeasure effectiveness easy to see for engineering, BD, and marketing stakeholders.
• Write scripts and small applications that support the GNSS/RFI team’s day-to-day workflow — log parsing, data ingestion, automation of repetitive analysis, lightweight internal apps.
• Work closely with GNSS signal-processing engineers and the test team to turn loosely specified requests into reliable, reusable software.

• BS in Computer Science, Software Engineering, Electrical Engineering, or equivalent.
• 2+ years of professional or substantial internship/project software engineering experience.
• Solid programming fundamentals in Python and at least one systems/compiled language (C/C++, Python, Go, Rust, etc.).
• Comfortable working with structured data and unstructured (CSV/JSON/binary logs) and building simple visualizations (e.g., Matplotlib, Plotly).
• Familiarity with version control (git) and basic software engineering practices (testing, code review).
• Strong problem-solving skills and willingness to learn RF/GNSS-adjacent concepts without prior domain expertise.

• Exposure to ML/AI development flow for training, inference, neural networks, pattern recognition, data correlation with physical phenomena.
• Exposure to signal/sensor data, embedded systems, or scientific computing.
• Experience building internal tools, dashboards, or test-automation frameworks.
• Familiarity with SQL/data bases or lightweight data pipeline frameworks.
• Interest in GNSS, RF, or navigation systems — no formal background required.

• 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
• Competitive compensation with stock options to share in oneNav’s long-term success
• Startup-style perks, team events, and a friendly, supportive environment
