We’re looking for a senior full-stack engineer to join our team at Umain. You’ll work on a mix of greenfield builds, product extensions, and system integrations, often in parallel and always in close collaboration with designers, strategists, and clients. 

Our team is based in central Gothenburg, working out of a modern, light-filled office on Kungsgatan. It’s designed for focused work, creative collaboration, and a relaxed daily rhythm. 

If you’ve thrived in agency or consultancy environments and enjoy bringing clarity and quality to fast-moving projects, this role is likely a good fit.

About the role

At Umain, we help ambitious partners design, build, and scale digital products. We shape ideas early, ship working software quickly, and evolve systems over time. Our teams are cross-functional and client-facing, and engineers are involved from discovery to delivery.

This role is broad by design. One month you might build a custom ecommerce frontend that connects to a backend system via APIs; the next, you could be designing a scalable backend for a logistics platform. You’ll move between different client needs and technical stacks, balancing fast delivery with thoughtful engineering. We value engineers who enjoy this kind of variety and care about both the quality of the work and the way it’s done.

What you’ll do

• Build modern frontend experiences using frameworks like Next.js, Svelte, or Flutter for web
  
• Design and implement backend APIs and integration layers using languages like Go, Kotlin or Typescript. We might also move in to Rust.
  
• Work with headless CMS and ecommerce platforms including Centra, Shopify, and MedusaJS
  
• Lead and contribute to short- and medium-term client projects, from concept to launch
  
• Collaborate with designers and strategists to shape what we build and why
  
• Support internal knowledge sharing and team practices across projects

Who you are

• A full-stack engineer with 5+ years of experience, ideally including agency or consultancy work
  
• Confident switching between frontend, backend, and dev tooling when needed
  
• Comfortable scoping work, clarifying ambiguity, and collaborating with non-engineers 
  
• Curious, pragmatic, and able to balance delivery speed with technical quality
  
• Strong communicator in both written and spoken formats

What we offer

• Varied, real-world projects that challenge and grow your skillset
  
• A team that values curiosity, autonomy, and direct communication
  
• A personal coach to support your development and wellbeing
  
• A transparent growth framework and fair, equal compensation
  
• Colleagues who take the work seriously but not themselves
  
• A flexible work culture that fits around your life, not the other way around

We are hoping to onboard a team of 2+ colleagues in October. We're growing fast and would love for you to shape the future with us.
