Senior Full Stack Engineer

POSTED ON 4/26/2025 AVAILABLE BEFORE 5/26/2025
Proper ApS København V, Copenhagen Full Time

Job description
Most companies run through gigantic spreadsheets twice a month to invoice their customers. This is boring and mistakes happen. Do you want to help solve billing once and for all?

We are a profitable startup, and we are expanding. You won't have to deal with any legacy code, no decisions made 10 years ago holding you back, just pure speed. We are looking for a Senior Full Stack Engineer. You are part of the entire process from understanding the foundational problem, designing the solution, and pushing a product out.

You will work closely with everyone in Proper and our customers. We build our products through a process inspired by experiments. First, we test ideas, and product market fit with prototypes, interviews, or other ways. Once we understand the job to be done and the market, we either move on to a prototyping stage with more software or proceed directly to writing code. This approach allows us to move fast, stay flexible, and confidently deliver high-quality products.

What's the job:

  • Help us find product-market fit with the new product.
  • Work in a small, focused product team with our co-founder.
  • Put together mockups, proof-of-concepts, iterate and ship fast.
  • Be part of choosing the right frameworks and technologies for the job.
  • Lots of focus time without rigid processes.

What we are looking for:

  • Strong technical skills with a flare for building products and solving real, painful problems for our customers.
  • Focus on customer needs rather than following a detailed specification.
  • Enjoy working independently and driving things forward on your own.
  • Excel in working with the entire stack; frontend, backend and cloud infrastructure.
  • Experience working on multiple different products from your past.
  • Strong communication skills and fluent in English.
  • Located in the Copenhagen area.

Technologies we use:

  • Kotlin, Java, AWS (SQS, SNS, DynamoDB, Lambda, CDK)
  • TypeScript, React, Next.js, Tailwind
  • Event-driven architecture
  • Domain-driven Design concepts
  • MacOS

We don’t expect you to be an expert in all of these technologies, however, we want you to be up and running fast, so you should have worked professionally with either Java or Kotlin, are familiar with the AWS ecosystem and have solid experience with building React apps.

Benefits:

  • Benefit from our warrant program, giving you a stake in the company's success.
  • Work in a unique office in central Copenhagen.
  • Enjoy a delicious and complimentary lunch.
  • Support from your manager with weekly 1:1s.
