Job Description

About the Role

We are looking for a backend Software Engineer to design and build scalable distributed systems across the full product lifecycle. You will develop reliable backend services, ensure secure data exchange, and support high-availability deployments, working closely with engineering and production teams from concept to deployment.

At Frankenburg, you’ll join a team of top experts in technology and national defence, developing next-generation missile systems. You’ll work in a fast-paced environment where your contribution has real impact on how we design and deliver advanced defence solutions.

Key Responsibilities

• Backend Development
• Develop, debug, and maintain backend software for distributed defence systems across embedded and general-purpose environments.
• System Integration
• Collaborate on hardware–software co-design, defining robust interfaces and supporting system integration and verification.
• System Communications
• Design and setup of system communications, including device configuration and network integration.
• Testing & Validation
• Support integration testing, troubleshooting, and system validation.
• Performance & Reliability
• Enhance deployment processes and system performance, ensuring robustness, reliability, and traceability.

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 C/C++, with Rust 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.
