Full-Stack Developer

You have a few years of experience in coding, and you have a favorite stack, but you also enjoy learning new languages, tools, and frameworks. You believe in choosing the appropriate tool for the task. You want to spend your days where your technical creativity and love for stylish, efficient code are allowed to flourish.

You keep it tidy and work agile. You're confident in your skills, but you're also open to learning from others, as well as letting others learn from you. Overtime is rarely needed because you and your team make a realistic plan from the start. This gives you peace and quiet, which increases the quality of your work and makes the job more fun. You build quality stuff, but you also know how to keep a deadline.

You want to work on a little bit of everything, from web apps and mobile apps to VR and IoT. You love new tech and don't mind tackling a new platform by building early apps on a beta SDK.

As a developer at Prototyp, you will often be in touch with clients, but talking about engineering solutions with non-engineers is not a problem for you. It's all about using good metaphors.

Maybe you have an engineering degree, or maybe you did something other than study and learned a lot of things that are useful in work life? You are, however, an easygoing person who likes to get nerdy in lunch discussions about everything from obscure popular cultural references in video games to how to cook vegan gourmet food.

At Prototyp we like to get our move on. We regularly go running, and walking meetings are a favorite. Everyone is entitled to one hour of paid workout time each week. Maybe that's not your thing? That's alright, too.

Apart from working with really great colleagues on meaningful projects, you'll like working at Prototyp if you enjoy:

• Working in small, tight teams

• Delivering projects on time without crunching

• Video games

• Board games

• Listening to music

• Creating music

• Soldering stuff

• Dismantling pop culture theories using logic

• Blockchain humor

As a Full-Stack Developer at Prototyp, you'll work in small, autonomous teams to design and build digital products for our clients — from early-stage prototypes to production systems. Your day-to-day will include:

• Developing web and mobile applications

• Frontend and/or backend development, depending on the project and your profile

• Technical discussions and collaboration directly with clients

• Contributing to architecture decisions and code reviews

We're looking for someone who has

• At least 3 years of professional software development experience

• A degree in computer science, software engineering, or equivalent experience

• Strong experience with at least one modern frontend framework (e.g. React, Vue, or Svelte) and/or backend development (e.g. Node.js or .NET)

• Experience with modern tooling such as Docker, CI/CD pipelines, or cloud platforms is a plus

• Familiarity with agile ways of working

• Professional proficiency in Swedish or English, spoken and written

Employment details

• Employment type: Permanent

• Scope: Full-time (40 hours/week)

• Salary: Individual salary setting in line with industry standards, set in dialogue based on experience and skills

• Work location: Prototyp Stockholm Office HQ

• Start date: By agreement
