Software Engineer - GNSS Systems (Tools, Test & Data) in Sunnyvale

Do you want to be part of oneNav’s disruptive next- GNSS products that are resilient in the field? We are seeking a Software Engineer to support oneNav’s Advanced Products & Systems team by building the software tools, test infrastructure, and data pipelines that power our GNSS solutions. This role is well suited to a strong, curious software engineer who can quickly get comfortable around RF/GNSS data and pick up domain concepts on the job and deliver high-impact solutions in a fast-paced environment., n \n

• Build and maintain software that automates competitive receiver testing across jamming/spoofing waveforms and rolls results into standardized KPI tables \n

• Build tools to mine and process huge log files to visualize trends and performance \n

• Create internal dashboards, plots, and heatmaps that make receiver performance, test coverage, and countermeasure effectiveness easy to see for engineering, BD, and marketing stakeholders \n

• 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 \n

• Work closely with GNSS signal-processing engineers and the test team to turn loosely specified requests into reliable, reusable software \n

• BS in Computer Science, Software Engineering, Electrical Engineering, or equivalent \n

• 2+ years of professional or substantial /project software engineering experience \n

• Solid programming fundamentals in Python and at least one systems/compiled (C/C++, Python, Go, Rust, etc.) \n

• Comfortable working with structured data and unstructured (CSV/JSON/binary logs) and building simple visualizations (e.g., Matplotlib, Plotly) \n

• Familiarity with version control (git) and basic software engineering practices (testing, code review) \n

• Strong problem-solving skills and willingness to learn RF/GNSS-adjacent concepts without prior domain expertise \n
