Ada Software Engineer

TYMIQ is looking for experienced Ada Developers to join a long-term engagement with a major European air traffic management organization. The client operates one of Europe's busiest and most complex upper airspace regions, and its Flight Data Processing System (FDPS) is a mission-critical, real-time system built predominantly in Ada, with a large code base of over 100,000 lines of code.

You will be embedded in the client's engineering team, providing technical support for the continuous maintenance and evolution of the FDPS. This is a hands-on backend engineering role in a safety-critical environment where reliability, quality, and full documentation traceability genuinely matter — the software you work on keeps live air traffic moving safely.

You will be employed by TYMIQ and assigned to the client's project on a stable, long-term basis. The client highly values staffing continuity, so we are looking for people ready for a multi-year commitment.

• Code development & review — implement and review Ada code changes in the FDPS environment, in line with approved change requests.
• Documentation — update requirements, design, and technical documentation to ensure full traceability and maintain an auditable documentation baseline.
• Testing & validation — develop test scripts and conduct unit and system testing to validate software modifications and ensure compliance with functional and safety requirements.
• Incident investigation — investigate incidents affecting the FDPS, identify root causes, and support corrective actions to restore normal operation.
• Agile delivery — work in Scrum/Kanban sprints using Jira and Bitbucket, under the guidance of the team leader; contribute to meeting agendas and minutes where required.

A typical week: reading and modifying Ada code in a large legacy real-time code base, peer-reviewing colleagues' changes, writing and running unit/system tests, keeping design and test documentation up to date, and picking up incident tickets to diagnose root causes — all within the rhythm of Agile sprints and close collaboration with the client's engineers.
