Senior Backend Engineer

Build technology that protects people, places, and everyday life.
Your work won’t sit quietly in a backlog. It will shape secure, connected solutions used around the world — and you’ll have the trust and freedom to do your best work along the way.
Why this role matters
At Assa Abloy, technology plays a direct role in creating a safer, more open world. As a Senior Backend Engineer, you’ll be part of teams building secure, scalable digital platforms that power smart access solutions globally.
This is a role for someone who wants to own meaningful problems, contribute to technical direction, and work in an environment where quality, balance, and long-term thinking genuinely matter.
The role
You’ll work as part of a small, cross-functional team with shared end-to-end responsibility, collaborating closely to drive work from idea to delivery and continuous improvement. The team owns both the direction and execution, with a strong focus on improving our customers’ hospitality experience.
In this role, you’re expected to take initiative and help move work forward, ensuring progress and alignment across disciplines. You’ll challenge assumptions, surface risks early, and contribute to sound technical decisions by bringing clarity, pragmatism and focus to complex discussions while helping the team deliver meaningful, high-quality outcomes.
What you’ll work on
Deliver meaningful features end-to-end — design, build, test, deploy, and evolve backend-focused services with a strong sense of ownership and quality.
Build modern, scalable systems — develop primarily in Java, Kotlin, Golang, collaborating with frontend engineers and contributing where needed to React/TypeScript applications.
Shape architecture and technical direction — apply Domain-Driven Design, Test-Driven Development, microservice and event-driven patterns to solve complex problems and raise the bar across the team.
Lead cloud-native development — design and operate services on AWS, using containers, orchestration platforms, and serverless patterns to build resilient, future-proof solutions.
Design data and system behaviour at scale — model data across NoSQL and relational systems, ensuring performance, reliability, and secure operation in distributed environments.
Strengthen delivery and operational excellence — improve CI/CD pipelines, support production systems, and continuously refine engineering practices for long-term sustainability.

What will help you succeed
Solid senior experience (5+ years) building backend systems in cloud-native, distributed environments.
Strong ownership mindset — you’re comfortable taking a feature from idea to production and standing behind your decisions.
Architectural judgement — you know when and how to apply DDD, TDD, microservices, and event-driven design pragmatically.
Hands-on cloud and DevOps experience — particularly with AWS, containerisation, CI/CD, and modern deployment models.
Experience leveraging AI-assisted development tools and methods to enhance productivity, code quality, and system design.
Clear, thoughtful communication and a willingness to mentor others.
