We Would Love You to Have Educational Background A technical degree or diploma in software engineering, computer science or a related field. Experience Backend development experience, preferably in distributed systems, with understanding of networking fundamentals and system communications. Technical Skills Strong proficiency in Python and Rust, with C/C++ as a plus. Good understanding of network communication protocols (TCP/IP, FTP, SSL) and UNIX-based operating systems. Soft Skills Proactive, solution-oriented mindset with exceptional communication skills. Delivery focused, with the ability to manage multiple priorities and meet strict deadlines. Mission Alignment Strong alignment with our mission to build affordable and mass-manufacturable defence technologies — ensuring every euro spent moves us closer to our goal. Security Clearance Willingness to undergo a background check as a condition of employment. Our Values Our mission is ambitious, and it takes a team that works with the same intensity. Own the Mission: Mission first. Always. We choose impact — we focus on what moves the mission forward fastest instead of “nice-to-haves". We fix it now — when delays or problems appear, we step up, rally the right people, and solve them immediately. We keep momentum — when time matters, we stay focused and move forward without waiting for perfect conditions. Strive for More: Dare more. Do more. Achieve the impossible. We challenge the status quo — we question, test, and improve instead of accepting “the usual way.” We embrace discomfort — we step outside comfort zones and turn challenges into growth. We anticipate the future — we build solutions that scale and set higher standards each time. Build with Trust: Be open. Keep promises. We walk the talk — what we say, we do. No excuses, no exceptions. We share openly — we communicate clearly and early, even when the news is hard. We own outcomes — we admit errors quickly, fix them, and prevent them from repeating.
