Senior Software Engineer (Frontend Focus) - Onsite Messaging

Tech Innovation at Apotea Apotea is Sweden’s largest online pharmacy. We are rebuilding our core platform on a modern cloud-native architecture and investing in our technology stack. In Tech, our vision is to move toward AI-first, automated and data-driven systems — not by adding AI on top of legacy workflows, but by redesigning how software is built and operated. We focus on scalable, observable systems owned by engineers end-to-end. We are now looking for Senior Full-Stack Software Engineers who want ownership, impact and engineering challenges. The Role As a Senior Full-Stack Software Engineer, you will design, build and operate distributed backend systems and modern frontend applications that power Apotea’s core products and emerging AI-driven experiences. You will own the full software lifecycle: architecture, implementation, deployment, monitoring and improvement — from database design and backend services in Go to frontend experiences for teams and customers. You will work with data engineers, ML engineers, product managers and business stakeholders to turn problems into production systems, including agentic AI applications where software agents interact with data, services and workflows. Key Responsibilities Full-Stack System Design & Implementation: Design and build backend services in Go for distributed, cloud-native applications. Build frontend applications that connect users to data, workflows and AI-powered capabilities. Build APIs and event-driven components across e-commerce, logistics, data and AI platforms. Design systems with scalability, resilience and observability in mind. Database Design & Data Ownership: Design application-level data models and database schemas. Make informed trade-offs between storage approaches. Understand query patterns and performance implications. Integrate operational systems with analytics and ML pipelines. Agentic AI Applications: Build production-grade agentic AI applications that integrate LLMs with real systems and workflows. Design services that enable AI agents to act safely with business data. Collaborate with ML and data engineers to operationalize AI in real products — not demos. Help define guardrails and patterns for reliable AI-driven systems. Engineering Excellence: Write clean, maintainable, production-quality code across backend and frontend. Participate in code reviews and architectural discussions. Build automated tests and CI/CD pipelines. Take responsibility for production reliability and incident resolution. Improve engineering standards, tooling and AI-assisted coding workflows. We are looking for someone with: Strong experience as a Senior Full-Stack Software Engineer building production systems. Proven experience with Go (Golang) in backend environments. Solid understanding of distributed systems and modern architectures. Experience building frontend applications. Experience with database design and application data modeling. Strong fundamentals: testing, versioning, CI/CD, documentation and code quality. Ownership mindset and ability to balance speed and quality. Excellent communication skills and collaborative attitude. Nice to Have Experience with A/B testing or experimentation frameworks. Familiarity with event-driven architectures and streaming systems. Experience with AWS and cloud-native architectures. Experience building AI-powered or agentic applications. Exposure to high-scale e-commerce, logistics or data-heavy environments. Knowledge of Infrastructure as Code, such as Terraform, CDK or CloudFormation. Why Join Apotea? A stable, future-focused company with a meaningful mission to improve healthcare accessibility. Work on AI, ML and automation projects that impact millions of customers. Work with modern cloud-native, automated and event-driven systems. Join a flat, agile organization with minimal bureaucracy. Grow through training, mentorship and industry conferences. Collaborate in a transparent, cross-functional environment. Own projects from concept to deployment.

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: 5+ years of Software Engineering experience Proficiency in Golang, or the confidence and track record to pick it up fast Experience with working in a Linux environment A product mindset — you think about impact, not just implementation Experience working in agile development environments. Familiarity with cloud platforms like GCP or similar Bonus points for: Experience with React Background in IoT or hardware-integrated systems Deeper knowledge of Linux and/or Ubuntu Core 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.
