Playground Dev is not the place for those who want to sit in a corner and guard their code like it is "The One Ring."

We want someone who thrives in Backend Engineering, and solving problems even more. At Playground, titles are secondary. What matters is your ability to deliver (inhouse as well as a consultant), your curiosity about AI, and your drive to teach and learn new things.

Why Playground Dev?

Here, you will work in an environment where the distance from idea to execution is minimal. We skip the unnecessary bureaucracy and focus on what we love: building tech. You will be part of a team where we support each other, geek out together, and celebrate wins while learning from our fails.

We do AI

We do not just talk about AI; we build and ship it. Here are some examples of what we actually do and the type of challenges you will be tackling with us:

• Mapping and Migrations: System mapping of massive enterprise codebases and automated migrations using custom-built AI agents.

• VC Intelligence: Automated due diligence tools for VC firms to analyze startup tech stacks, architecture, and risks.

• Anomaly Detection: Real-time identification of deviations and events using AI agents to catch what humans miss.

• Next-Gen Interfaces: High-end chatbot solutions for global brands launching new products.

• Automated Insights: Deep integration with tools like Microsoft Word to automatically generate complex analysis reports based on real estate market data.

What you'll do

We are a group of enthusiastic tech and AI nerds (no "ninjas", just a a group of sound people, hopelessly interested in tech and what tech can do for humans).

Together, we build advanced systems, experiment with new models, and probably have at least one side-gig or passion project running just because it is fun. We value skills and genuine interest over fancy diplomas. Are you self-taught? Great. Do you have a Master’s degree? Also great. What matters is what you can do with the code, and how you are with people.

Who are you?

You are technically heavy and thrive in the backbone of the system. You are a specialist in building logic that scales, but you are not dogmatic about a single language. You prefer the right tool for the job.

• Backend is your home turf. Whether your mother tongue is Go, Node, Java, or C#/.NET, you know how to write robust and scalable code

• You are a doer. You like seeing results and understand that great code is code that actually reaches production and solves real problems

• AI-curious. You do not need to be a Prompt Engineer yet, but you see the potential in AI and want to be where the action is

• No Gollums. We have no room for lone wolves who hoard their knowledge. You share what you know, you are approachable, and you understand that we are stronger as a team.

Skills & Requirements:

This is the role for someone who wants to focus on the backend but understands the bigger picture:

• Must-have: Deep, hands-on experience in at least one of our core backend languages (Go, Node, Java, or C#/.NET).

• Nice-to-have: Experience with cloud environments such as AWS or GCP, or having tinkered with LLMs and AI integrations.

• The X-factor: A genuine interest in tech. Maybe you have built your own bot, run a home server, or contributed to open source? Tell us about it!

• Language requirements: Fluency in Swedish and English, as most (not all though) of our collaborations and client projects are conducted in Swedish. Some also require extended background vetting.

Let's Play!

Applying to us is a breeze, at least according to us =)

• Upload your resumé or use your Linkedin profile

• Answer the choice-questions (no "please-rewrite-your-resume" nonsense, promise)

• Feel free to include links to your portfolio, GitHub or similar if you have stuff you're proud of that you want to share with us (or epic fails and the learnings you took from that)

Important notes:

• Playground Group does not provide visa sponsorship or relocation support

• Applicants must already have a permanent and independent right to work in Sweden

• As part of the final stage of the recruitment process, a background check conducted by a third party will be carried out.
