Salary Competitive

Good to see you here, Dev! As you probably figured, we are looking for reinforcements to join our team. We seek people with a passion for code and the curiosity to understand how the world works 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 beat skills over time, skill 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? Interested to hear more?


As a Back-end Developer, you are going to...

  • Be an essential part of our backend team.

  • Design and build fast and simple APIs to serve our mobile/web apps and to connect with third parties.

  • Design and build microservices to process big data.

  • Dive into the true meanings of different data points and discover use cases for them.

  • Actively participate in data design.

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

This means that you'll need to...

  • Be proficient either in Python or JavaScript (Node.js).

  • Know SQL (PostgreSQL).

  • Be very exact what it comes to data.

It would be of help to also...

  • Know Kafka.

  • Know GraphQL.

  • Have good experience in working with APIs.

  • Have experience in cloud servers (Google Cloud).

  • Know the basics of machine learning.


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 new 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 not support full-remote working since we believe that physical presence plays a significant role in culture-building and effortless communication. Still, once you've worked with us, 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.
