Backend / Full Stack Developer (Node.js)

Salary Competitive

Good to see you here, Dev! As you probably figured, we are looking for reinforcements to join our team. We are seeking specifically people with a passion for code and the curiosity to understand how the world works in order to find the meaning in all we do.

It's definitely an asset to have a profound competence in some of the technologies we are using – or going to use. We do need people that can extend our skillset right from the beginning. But since passion and curiosity always beat skills over time, that is not the primary thing we're looking for.

Our product is a wide combination of design, psychology, data acquisition, data processing, data analysis, web and mobile interfaces, various databases, cloud servers, and APIs.

In the end, it's a negotiation AI that handles conversations better than human beings. To work, the system must have the best possible data available and the capabilities to figure out the next move and to generate the natural language to communicate it. Sounds like a challenge you're up for?


As a Backend Developer, you are going to...

  • Be an essential part of our App team that develops the components that interact with our users.

  • Be responsible for creating and optimizing APIs (mostly with GraphQL) and their functionality so that the mobile/web apps can have the desired features.

  • Actively participate in data design.

  • Apply Clean Code principles, test your code, and review others' code

This means that you'll need to have good skills on...

  • JavaScript (Node.js)

  • GraphQL

  • SQL (PostgreSQL)

It would definitely be of help to also...

  • Know React

  • Know Kafka

  • Have experience in REST APIs

  • Have experience in cloud servers (Google Cloud).


What are we exactly looking for?

Most likely, you have spent many years playing (i.e. trying things) with computers and done many projects either at work or in your free time. You have countless times felt the pain of banging your head on nasty problems, but you also yearn for the feeling of coming through as a winner. You know that StackOverflow has all the answers, but you have spent so many hours googling for the basic bugs that you don't get stuck on them anymore – at least daily. You have an "anything is possible – time is the only concern" kind of attitude.


When you join us, you are going to be trusted – probably more than you'd ever expected. We are a small, fast-learning team that you can lean on and spar with, but who also expects you to look for the answers and bring solutions to the table. We trust that every one of us is actively looking for ways to make our system better, to make our customers happier, and we believe that every one of us can discover the next big idea that takes us forward. We are, above all, honest and respectful.

You'll get the best tools you need and a fair salary. We do believe that physical presence plays a significant role in culture-building and effortless communication, but once you've worked with us some time, part-remote work is a way of doing your thing.

Working at
Stealth Black Oy

We believe that conversations and negotiations – especially in a business-to-business context – are not ideal. Our skewed motivations and insufficient knowledge about the situation lead to suboptimal proposals: we say things that do not matter and leave some essentials unsaid. We waste everyone's time discussing with the wrong people, and we make deals that are actually bad for us. We at Stealth Black believe that a computer that sees things just as they really are and knows everything about everything can make a difference here. We are building the guardian angel that sits on your shoulder, guides you forward, and watches your back.
