Senior Software Engineer | Box Team

Where software meets the physical world In 2022, Budbee and Instabox merged to form Instabee — now home to three consumer brands serving millions of deliveries across Europe. We move fast, we're growing across Scandinavia and continental Europe, and we're not slowing down. Always with the consumer at heart. The Team The Box team owns one of Instabee's most tangible products: our locker network. We build and maintain the full software ecosystem that powers 6,000+ lockers — from cloud backend services to the software running on the physical hardware itself. It's a space where reliability, scalability, and real-world constraints collide daily, and where the gap between a code change and a real-world outcome is remarkably short. We operate as an autonomous, cross-functional team with full ownership of our product lifecycle — from design and development through to deployment and iteration. If you've ever wanted to see your engineering decisions literally open a door, this is that job. What You'll Work On The team’s focus and responsibilities span a wide range of areas, but everything is centered around the user experience at the parcel lockers. This means working with supporting backend solutions (Golang), the user interface at the locker itself (React), cloud services (Google Cloud), and other related applications. With our roadmap mainly centered around the locker experience, much of the engineering work focuses on building and evolving the software that powers the devices themselves. It’s a pragmatic, flexible environment where no two problems look the same. As a Senior Software Engineer, on a daily basis, you'll: Shape the architecture — Contribute to key technical decisions and drive solutions that balance robustness with speed of delivery Work across the stack — Hands-on implementation from cloud services to hardware-adjacent software Collaborate closely — Partner with product managers, designers, and engineers to refine requirements and build things that matter Raise the bar — Code reviews, knowledge sharing, and continuous improvement of systems and processes Who You Are You're a pragmatic engineer who enjoys working across boundaries — backend and frontend, software and hardware, ambiguity and clarity. You take ownership, collaborate naturally, and care about how your work functions in the real world. You bring: Senior-level Software Engineering experience Proficiency in Golang, or the confidence and track record to pick it up fast Experience with working in a Linux environment You think in business outcomes, not just technical solutions Familiarity with cloud platforms like GCP or similar Bonus points for: Experience with React Background in IoT or hardware-integrated systems Deeper knowledge of Embedded Linux The Culture We believe great products are built by teams that take real ownership and understand how their work is used in the world. In the Box team, that's not a platitude — it's the daily reality. You'll work in a highly collaborative, autonomous environment where experimentation is encouraged and fast iteration is the norm. Open communication, continuous learning, and genuine cross-functional partnership are how we operate. You'll have real influence over technical direction and product experience — not just tickets in a queue. What You'll Get Ambitious colleagues, real challenges, and plenty of room to grow.
