C# API Implementation Engineer

Salary Competitive

You prefer to code by example, rather than reading a thousand pages of specification. You enjoy technical puzzles and figuring out the underlying implementation of the systems you interact with. You might even have created elegant solutions for boring manual processes based on scraping.


To us personal finance is not about calculations and formulas but about lives being lived, emotions and money habits. The same goes for programming - it is not about the tools. We believe that the best results come from passion, dedication, intelligence - and natural curiosity.

We've been building a very successful personal finance platform, Spiir, for the last 7 years. Lately, we have carved out some of the main technologies of Spiir and turned them into B2B solutions allowing companies to build innovative solutions on top of data from Nordic banks. We call this solution Nordic API Gateway.

Being digital is the core of our company. We have no silos. No business versus IT or marketing versus product. We work together to achieve our goals. You are going to be a central part of the company and pitching in with new ideas is a must. We help each other to strive for perfection. 

We want to grow our bank integrations team. They turn the results of reverse-engineering iOS & Android mobile apps into sustainable production grade APIs. We need you to supervise our code quality and put even more APIs into production on network traces delivered by our reverse engineers.

Through the Nordic API Gateway, the team created access for our customers to more than 350 banks. Before that launch, no public APIs were available in this industry. We successfully re-implemented more than a handful of industry-wide heavily hardened black box security frameworks along with numerous device binding solutions. We have extensive monitoring capabilities and we always strive to be a step ahead of any roadblocks.
