JavaScript Developer (Fullstack)

Open position in 🇸🇪 Stockholm, Sweden

Hello, nice to meet you!

We are tretton37 - created by developers, for developers. We are a knowledge and culture-driven company on a mission to fight bad code, one line at a time. Since 2010, we have grown to almost 280 handpicked craftspeople from all around the world. We love to learn as much as we love to work within a company that embraces a kind and supportive atmosphere. We value work-life balance and social activities such as summer gatherings where everyone's whole family is invited, monthly lunch and dinner events, and sports activities. Our mission “Enabling people and organization with technology excellence” is without a doubt a central part of everything we do.

I love working at tretton37 because of our focus on craftsmanship and quality. tretton37 and our customers expect me to spend the time and effort to write great code, not just provide a pair of hands at a keyboard.

- Helen Toomik, Software Developer @tretton37

We wish our next colleague to have at least 3 years of professional experience in:

  • Creating mid to large-scale web applications with JavaScript (ES6 +)  
  • At least one major frontend framework (React, Vue, or Angular)
  • Writing server-side code with node.js

And that you have some professional experience in: 

  • Writing code that is clean, reusable, and testable
  • Relational or NoSQL databases and containerization
  • Building and consuming APIs
  • Writing tests on both the frontend and backend

But most of all, we wish that you have a thirst for knowledge - always staying curious, keeping up-to-date, and sharing what you know!

What are our expectations?

We understand that you are probably not equally skilled in both frontend and backend, but that's not what this position is about. We are looking for an experienced developer that enjoys working with both backend and frontend as well as solving software problems end-to-end. Above years of experience and past job titles, the key attributes we are after are a passion for delivering high-quality work, an ambition to get the job done, and an enthusiasm for continuous improvements. 

What will you do? 

  • When you put a bunch of brilliant minds together, anything is possible. We always aim to work with projects that are technologically advanced and full of exciting challenges. 
  • We like to get involved with a project at an early stage - when we can influence and set high technology standards, infrastructure requirements and start our hardcore development process. 
  • We cover the entire product and service pipeline, from high-performance scalable backends to stunning interfaces for all devices - always with first-class quality and satisfied clients in mind. 
  • At the end of the day, what truly matters to us is the impact that we are able to create through technology; either for our clients or the community.

We put knowledge in the spotlight - this is what you get: 

To assure that we never stop gaining and sharing knowledge among ourselves, with our clients, and with the community, this is a selection of our "knowledge buffet": 

  • Competence groups, code lunches, local and international conferences, and masterclasses are some examples of how we meet up, socialize and share knowledge within the organization.
  • Some examples of our contributions to the community are our community conference leetspeak, live-streamed knowledge sharings, and hackathons.
  • Combine all this with the freedom of having your own knowledge budget to be spent on conferences, additional tooling, education, licenses, or gadgets, along with a supportive family spirit on top of it all.
