Instabee Group AB

About the Team We are the team responsible for ensuring that parcels move through our terminal network in the most efficient and cost-effective way possible. Our systems provide sorting instructions that guide parcels between terminals and to their final destinations, whether that’s a customer, parcel locker, or delivery partner. We also deliver real-time parcel data and location insights, enabling smooth and transparent operations across our entire sorting network. Our Vision Our objective is ambitious, We strive to achieve operational excellence across our 40+ terminals in Europe. Any parcel should be able to enter the terminal sorting network at any point and immediately be ready for the next step towards its destination. To achieve this, we ensure that everyone interacting with a parcel — from systems to people — can make smart, fast, and data-driven decisions that minimize the total cost of the flow. How We Work We are a team that listens to what’s needed now, tomorrow, and in the future. Collaboration, experimentation, and continuous improvement are at the heart of how we operate. The team consists of our Engineering Manager, three skilled Backend Engineers, a Product Manager, and a Staff Engineer. This recruitment is to replace one of our Backend Engineers who recently resigned. About the Role As a Senior Backend Engineer in the Sorting team, you’ll play a key role in shaping how parcels move through our network. You’ll take ownership of projects, features, and the team's scope, from design to delivery, and collaborate closely with engineers, product managers, and stakeholders to solve complex problems that directly impact our operations. You’ll also act as a mentor and technical coach for other engineers, helping to raise the overall technical bar of the team. When things break (as they sometimes do), you’ll be trusted to lead the way in resolving critical issues calmly and effectively. What you'll do Take ownership of designing, implementing, and delivering backend features and projects within your domain. Break down complex engineering challenges and guide others through solving them. Write clean, maintainable, and well-documented code that your peers regard as high quality. Lead by example in ensuring system stability, performance, and scalability. Contribute to and improve our technical roadmap — identifying gaps and proposing meaningful improvements. Mentor and onboard other engineers, fostering a high-performing and collaborative team culture. Participate in incident management and ensure learnings turn into long-term improvements. Collaborate across teams and domains to ensure smooth integrations and a unified technical approach. About You You’re an experienced backend engineer with solid experience in Go (or a similar strongly typed language). We mainly work with Go, but you'll touch legacy systems built in JavaScript, Python, Java, or Kotlin. If you’ve seen a bit of everything and enjoy bringing old systems up to modern standards, that’s a bonus! You have a deep understanding of building distributed systems and APIs in a cloud environment (preferably GCP or AWS). You balance long-term stability with short-term delivery needs, and you care about quality. You’re proactive, when you see a problem, you raise it and help solve it. You enjoy mentoring others, giving and receiving feedback, and contributing to a strong engineering culture. You’re comfortable with ambiguity and confident making decisions that move things forward. You understand how technology and operations connect, and you want your work to have a real impact. What you’ll get We can promise you that you will be challenged, develop your skills and have the opportunity to work with truly amazing and competent colleagues. If you like changes and want to set new processes and ways of working - this is the place for you!
