We're a dynamic team where you can shape the future, ship groundbreaking solutions, and scale your abilities in many different ways.

- Backends handling tens of thousands of requests per second

The office in Stockholm is our default workplace, but we stay flexible when working from home makes sense for the team or the project. We trust each other to coordinate and keep things professional.
Most of our work is built in Kotlin, Go, and TypeScript, and we aim to pick the tools that best fit each project so our teams can focus on delivering the right solution.
The role is broad but centered on backend. You'll work on projects for both Swedish and international companies, including systems that integrate external services, automation, and frontend clients.
Building high-performance backend systems in Go, Kotlin, TypeScript (Node.js), or Python, depending on the project.
Working with frameworks such as Ktor, Fiber, and NestJS.
Designing cloud-native systems with Infrastructure as Code (Terraform) across AWS, GCP, and Azure.
Developing robust data models and database architectures to support application requirements.
Building observable systems with the right metrics, logs, tracing, and alerting to understand and operate what we ship.
Building and maintaining CI/CD pipelines with containerized deployments and scaling strategies.
If you're excited by working across the stack, always learning, and making a real impact at scale, we believe you'll feel at home at Umain.
Who You Are:
5+ years of experience building and running backend services in production.
Comfortable owning a system end to end, from API design to deployment and operations.
Strong in at least one of our core languages (Kotlin, Go, or TypeScript), and willing to pick up others as projects demand.
Experience making technical decisions on a team: weighing tradeoffs, reviewing code, and mentoring peers.
A product mindset: You think about maintainability, user impact, and long-term health, not just the ticket in front of you.
Familiar with agentic development tools
You treat unfamiliar problems and new technologies as an opportunity rather than a risk. In consulting, the next project often looks nothing like the last one, and you see that as a feature.
What We Offer:
A personal coach and support to help you develop both professionally and personally.
A range of diverse projects that explore and push the boundaries of what's possible.
A fun and fair work environment where you can grow through meaningful challenges and great colleagues.
Multidisciplinary teams where backend engineers work closely with product, design, analysis, and testing.
Working alongside some of the largest and most forward-thinking brands on the planet.
Skills Over Degrees
We're more interested in what you can do than in the diplomas you hold. Talent, drive, and creativity are what count at Umain. Here, you'll find opportunities to grow, learn, and excel in your career, regardless of your educational background.

The check is carried out only with your consent and is ordered by our CISO through our approved screening partner. The scope of the check depends on the role level.
