Job Advertisement: Software Product Engineer (m/f/d)
Location: Berlin, Munich, Remote (Germany, EU) 
Working Hours: Full-time 
Start Date: Immediately or by arrangement
About Us
Project Q GmbH (&quot;Q&quot;) is a Germany-based DefenceTech company with offices in Berlin and Munich. We network market-available sensors into a tactical IoT backbone that reliably provides armed forces and security agencies with a cross-domain information superiority-automated, scalable, and cost-efficient.
Our solutions integrate seamlessly into existing defence and safety infrastructures, offering fast data fusion and AI-enhanced analytics to deliver robust situational awareness in dynamic environments. We build platform-agnostic systems that enable real interoperability across domains.
As a Software Product Engineer, you'll join a focused, deeply skilled team to help build and extend our European open-core integration infrastructure. This includes Hydris: our integrate once, deploy everywhere, open source orchestration plane. Hydris, and its growing ecosystem of partner integrations, are where heterogeneous real-world systems like radars, AIS receivers, mesh radios, satellite feeds, AI analytics, and C2 platforms become one coherent picture, in conditions that are bandwidth-constrained, intermittently connected, and unforgiving.
What you'll do
This role is broad by design. You'll be trusted to take problems end to end: talk to users, shape what gets built, write the code, ship it, see how it performs, and decide what comes next. Day to day that means core engine work on Hydris in Go and TypeScript, extending it with features that genuinely move the field, and helping grow the ecosystem of certified integrations. It also means collaborating across our tech org and helping build and extend our integrated, software-defined customer solutions. And it means setting technical standards: how we test distributed behavior, how we version protocols, and how we keep an API-first product backward compatible.
Who this is for
You build software systems. You've shipped real products that people rely on, and you can show them to us. You care about building the right thing the right way, and about seeing it through. You want to travel when needed or possible, to be with the user, to understand their needs, and build directly to those. And you do your best work where the decisions are meaningful and the problems are challenging. This is a role that will demand the excellence you challenge others to show in their own work and conduct.
How you work<ul><li>
Self-starting. You don't wait for a perfectly scoped task; your default is to try something and learn from it.</li><li>
Deeply curious. You'll go down the rabbit hole and come back with something the rest of us didn't know we needed.</li><li>
Builder first. You'd often rather have a rough thing in someone's hands this week than a perfect plan for next quarter.</li><li>
Standard-setting. You join a team to raise its bar. People tend to work a little differently because you're in the room.</li></ul>
You should apply if you have<ul><li>
Taken new products from concept to scaling in-market, and lived with the weight of users, edge cases, and keeping it healthy under load.</li><li>
Worked across the full surface: product sense, design instinct, full-stack, deployments, the documentation that empowers other developers, and the long-term maintenance of what you build.</li><li>
Made calls under uncertainty with incomplete information, and owned the outcomes, good and bad.</li><li>
Earned the respect of engineers you respect. The best people you've worked with would take your call.</li><li>
Built a deep, principled, and broadly applicable skill set through substantial work and study.</li><li>
Eligibility to obtain a security clearance.</li><li>
Comfort working confidently in English.</li></ul>
You'd be a great fit with<ul><li>
Experience building secure systems for adversarial or contested environments, including threat modelling, secure-by-design practices, and hardening against real attackers.</li><li>
Experience with geospatial systems, sensor fusion, AI/ML analytics, or track management.</li><li>
Familiarity with defence or ISR data standards like CoT/TAK, ASTERIX, SAPIENT, MIL-STD-2525.</li><li>
Background in networking, mesh architectures, IoT integration, or systems built for contested or degraded communication environments.</li><li>
Experience on developer-facing open-source infrastructure where adoption depends on the quality of the API and documentation.</li><li>
Professional proficiency in German (and extra bonus points for additional European languages).</li></ul>
We Offer<ul><li>
Be a part of our growth story and help build us a leading technology company.</li><li>
A varied and responsible role in a dynamic company.</li><li>
Flat hierarchies and a pleasant working environment.</li><li>
Opportunities for professional and personal development.</li><li>
Flexible working hours and remote work options.</li><li>
Attractive salary and additional benefits.</li></ul>
