Job description

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.

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

• 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.
• 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.
• 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.

Qualifications

• 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.
