We want you as a talented Software Functional System Verification & Validation Engineer to help us in our mission by making sure that Nyx's flight software does exactly what the system needs it to do, and that this is proven at the right level of test.

Key Responsibilities

In your capacity as a Software Functional System V&V Engineer, your role will be continuously evolving, but day to day your duties will include:

• Keep a holistic view of the system-level software functional requirements and ensure they are correctly implemented and verified.

• Decide, per requirement, the right verification level: low-level unit test, SIL scenario, PIL run, HIL run, or vehicle-in-the-loop run.

• Define, plan, and execute verification campaigns across these levels, and analyse and report the results.

• Work day to day with the functional chain responsible in each subsystem team to define functional chains, test cases, and required test facilities.

• Dive into the details when needed: analyse failures in the code and make hands-on adjustments to test scripts, test harnesses, and software, in coordination with the FSW team.

• Maintain traceability from system requirements to implementation and verification evidence.

• Review test descriptions, expected inputs and outputs, and verification reports for completeness and correctness.

• Triage test failures, drive issue resolution with the FSW team, and manage related deviations and waivers.

• Prepare test readiness and review material, and report verification status to the FSW lead and the Chief Engineer.

In the role of Software Functional System V&V Engineer, ideally you will have the following:

• Degree in Aerospace, Software, Electrical, or Computer Engineering, or a related field.

• 5-10 years of experience working on complex space projects, including software verification and validation of embedded, real-time, or safety-critical systems.

• Hands-on experience with at least two of: SIL, PIL, HIL, or vehicle-level test campaigns.

• Holistic system thinker who is also ready to go into the code and make adjustments when the details require it.

• Strong C/C++ reading and debugging skills, plus scripting for test automation (e.g., Python).

• Solid understanding of spacecraft subsystems and how functional chains span them (e.g., AOCS, power, thermal, propulsion, avionics).

• Experience with requirements management and traceability tools.

• Structured, precise, and ownership-driven, with the ability to align multiple subsystem teams.

• Clear written and verbal communication in English.

Nice to have

• Experience in flight software on spacecraft or launch vehicles.

• Familiarity with NASA & ECSS standards for space software and verification.

• Experience operating or setting up SIL, PIL, HIL and/or vehicle-in-the-loop facilities.

• We’re Agile - we make decisions fast whilst keeping our goals and systems in mind
