Senior QA Engineer

JR Technologies is looking for a Senior QA Engineer to join our Engineering team. This is a hands‑on individual contributor role for someone who operates at the intersection of automation engineering and quality, someone who builds robust test frameworks, owns automation end‑to‑end, and is actively deploying AI‑assisted tooling as a genuine part of their daily work. We operate in airline retailing, distribution, and payment processing, which means quality is mission‑critical.

Our systems process real transactions for airlines and travel sellers globally, and the bar for reliability is high.

• We are considering candidates based in Europe only.
• For candidates based in Greece, both a regular employment contract and a contractor engagement are possible.
• For candidates based in other European countries, the position is available on a contractor basis only.
• Candidates based outside Europe will not be considered for this position.

At JR Technologies, our vision is to create the new customer‑centric distribution landscape of tomorrow. Working with us offers many opportunities to experienced professionals who are interested in joining a strong team, learning and mentoring in a dynamic environment, honing professional and technical abilities, and who thrive on new challenges. We provide an environment where people can leverage their skills, talents, experience, and interests to grow professionally and build rewarding careers.

As a disruptive company, our future depends on our capacity to innovate with a sense of drive, purpose, and urgency.
