Software Engineer (Private Wireless Network)

We’re looking for a Software Engineer to join the squad behind Onomondo’s Private Wireless Network Core – the breakthrough product that recently powered the world’s largest private LTE deployment at sea. Already proven in the field, this product is now scaling into a flexible, enterprise-grade solution for industrial customers across shipping, automotive, logistics, and beyond. You’ll play a pivotal role in building and evolving the software powering this unique connectivity product, working at the intersection of telecom infrastructure, distributed systems and modern DevOps practices. From customer pilots to scalable deployments, you’ll help us define how this solution performs, scales and delivers value across industries. You’ll be part of a cross-functional squad that has full ownership of the product, a Program Manager and commercial collaborators. Together, you’ll shape a solution that is both visionary and reliable, with a strong emphasis on customer needs, operational excellence and future-proof architecture. As one of the engineers at Onomondo, you’ll play a key role in shaping our engineering craft, tech strategy and culture. You’ll work closely with Engineering Leadership to ensure we’re building systems that scale, not just in size, but in impact. Not ticking every box? Ask yourself: “Am I excited about this role?” If yes, we encourage you to apply. You might be the perfect fit for this or another role. What you’ll be doing: Build and scale our Private Wireless Network Core: Develop the software systems that power our hybrid public/private LTE infrastructure and turn it into a repeatable, enterprise-ready product. Own solutions end-to-end: From early prototypes to production-grade systems, including architecture, implementation, and support. Collaborate with product, infra and commercial teams: Turn real-world customer problems into elegant, scalable software solutions. Focus on performance, reliability and maintainability: Build systems that scale globally, perform consistently, and are easy to operate. Help shape our engineering practice: Mentor other engineers, contribute to internal tooling and evolve our tech stack and ways of working. What you bring: Proven experience as a backend or full-stack engineer working on complex, distributed systems. Deep familiarity with networking, connectivity, infrastructure, or telecom systems (or a strong desire to dive into this space). Experience with Go, JavaScript, or similar system-level languages. TypeScript experience is a bonus. A strong grasp of cloud infrastructure, containerization (Kubernetes, Docker) and modern DevOps practices. Experience working closely with Product Managers and cross-functional teams to ship impactful products. A mindset of continuous learning, ownership and collaboration. You might be a great fit if you: Are based in Copenhagen. Thrive in ambiguity and enjoy creating clarity through hands-on problem-solving. Are comfortable working in customer-facing squads, turning real-world challenges into technical strategy. Enjoy working with infrastructure and low-level systems, but with a product mindset. Value simplicity, pragmatism and engineering excellence. Are motivated by building something ambitious – not just technically, but in how it shapes the future of global connectivity. Why join Onomondo? We’re not just building another connectivity layer – we’re reimagining how global IoT connectivity works from the ground up. With customers like Maersk and global use cases across industries, we’re tackling problems that have never been solved before. This is your chance to own and build something truly unique and help bring it to life for customers across the globe.
