For U.K. Roles: To comply with U.K. regulations, this role requires Baseline Personnel Security Standard (BPSS) checks, and successful candidates must be eligible to obtain UK Security Clearance (SC). ## Description Xona is the navigational intelligence company bringing real-time, centimeter-level certainty to any device, anywhere on Earth. With Pulsar - the world's most advanced PNT satellite infrastructure in Low Earth Orbit - Xona will offer a future-proof, backwards-compatible global positioning system optimized for absolute precision, superior power, and robust protection. You will design, build, and execute structured software test procedures that validate spacecraft Flight Software (FSW) across integration milestones, system-level campaigns, and environmental test events. You will translate requirements, ICDs, and operational concepts into repeatable, high-signal procedures with objective pass/fail criteria, then execute those procedures on real hardware and integrated test environments to produce flight-ready verification evidence. This role combines software test engineering, system integration, automation, and hands-on test operations. You will work closely with the Flight Software team to ensure features are testable, measurable, and validated under nominal and off-nominal conditions prior to launch. Space experience is not required. We welcome candidates from robotics, autonomy, automotive, aerospace, defense, or other mission/safety-critical systems. What You'll Do * Develop and maintain detailed Flight Software test procedures covering nominal mission threads, off-nominal scenarios, fault responses, safing behavior, and recovery workflows. * Translate requirements and ICDs into structured procedures with defined preconditions, configuration baselines, operator actions, expected results, and measurable pass/fail criteria. * Build and maintain test software and utilities (command sequencing, telemetry validation, log capture, automated reporting) to execute procedures reliably. * Run integration and regression campaigns on development benches, integrated avionics stacks, and HIL/SIL environments. * Implement fault-focused scenarios to validate FDIR behavior, limit monitoring, safe-mode entry, and recovery logic. * Own test data collection and time correlation, including telemetry, logs, performance metrics, and relevant instrumentation. * Develop and maintain live monitoring and post-test dashboards (e.g., Grafana) to track system health, event timelines, and test progress. * Support environmental test campaigns as a primary test operator when required, executing runbooks and maintaining disciplined event logs. This Role Is a Strong Fit If You Come From * Experience producing structured verification evidence and disciplined test reports. ## Related Videos - [Testing .NET applications a Tool box for every developer](https://www.wearedevelopers.com/videos/704-testing-net-applications-a-tool-box-for-every-developer) - [Dirty Tests And How To Clean Them](https://www.wearedevelopers.com/videos/515-dirty-tests-and-how-to-clean-them) - [Playing Pong on a shoulder press machine](https://www.wearedevelopers.com/videos/100140-playing-pong-on-a-shoulder-press-machine) - [5 steps for running a Kubernetes environment at scale](https://www.wearedevelopers.com/videos/88-5-steps-for-running-a-kubernetes-environment-at-scale) - [SMART Test Automation - the experience of legacy transformation](https://www.wearedevelopers.com/videos/100215-smart-test-automation-the-experience-of-legacy-transformation) - [Stop Guessing, Start Measuring: Evaluating RAG Systems with Synthetic Test Data](https://www.wearedevelopers.com/videos/1982-stop-guessing-start-measuring-evaluating-rag-systems-with-synthetic-test-data) ## Related Articles - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Software Engineer Salary in The UK](https://www.wearedevelopers.com/magazine/231-software-engineer-salary-in-the-uk) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london)
