Developer (Backend focus)

If you are a developer with JavaScript skills and interested in building end user focused and data driven product from the beginning, this might be something for you!

The product

We are building a new product that is a spin off from the core Vainu platform. It is based on the belief that by matching companies' internal and other datasets with external company data we can create something that will change how people view sales and marketing software. Our system contains billions of company data points and they are ranked, scored and presented in one simple and actionable interface. The end result: sales and marketing knows where to contact and why without any manual work or data input.  We are happy to show more as we meet!

We have our internal experience and it proves the first steps right. It’s internally kicking and alive and used by a salesforce of nearly hundred people across Europe. Already now, the results are overwhelming. We want to get the number of users hundredfold in less than two years. Are you up for it?


We are a three man band and are looking a fourth (wo)man to join! We have experience in design, engineering and business. On top of that we occasionally borrow some resources from Vainu’s own R&D.


We prefer people who have the courage to take decisions on daily basis on how problems are solved. To achieve that we also would like you to understand basic things about how businesses operate - our product is centered around daily business interactions, marketing and sales to be specific.

Our keywords at the moment:

  • JavaScript (preferably React) (+ 2yrs experience)
  • Node.js 
  • PostgreSQL

The Role

You will be part of a team building a product that has global ambitions and a long term vision. We are facing lot of interesting problems to be solved around our backend - how data flows through the system as our user base expands. Therefore we need you there,  at least in the beginning. 

Other than that, our daily work could be summarized as:

  • Influence: You have the luxury of being part of building a product that has a strong, end user focused and data driven vision. The team behind  the product has been able to build one of the most successful startups in the Nordics in the past five years.
  • Meritocracy: Come as you are - you will become part of a no bullshit team. We set our own rules with one rule mind: results matter. So far we haven’t decided to play fussball in hoodies or participate in pitching contests. We know what to do and we want to get it right from the beginning.
  • Data: We want to put data usable in our application. Our wealth of data gives endless possibilities to build intuitive interfaces, unbeatable analytics and competitive edge that haven’t been seen before.
  • Track record: As Vainu have grown to an almost 200 strong company in five years, we also offer you all the same benefits that belong to any other employees. People enjoy working in Vainu - Our employee net promoter score was 49. You’ll have best of both worlds -  freedom to operate and innovate in a solid company!
