Credit Developer

Get an idea of the role

We’re looking for a System Developer to join our Credit team and work hands-on with our credit decision engine (Provenir). This is a technical role where you’ll combine development, scripting and testing with real business impact.

You’ll work at the intersection of development, credit and IT, building and maintaining the logic that drives our credit decisions across Nordic markets. The role is structured and detail-oriented by nature - translating policies into system logic, configuring rules, and ensuring stable, high-quality decision flows.

This position suits someone early in their career who wants to start working with production systems, APIs, automation, and real-time decisioning. You’ll collaborate closely with experienced specialists in the area and gain deep insight into how modern credit platforms operate in practice.

What you will do

You’ll be part of developing and maintaining our credit engine, with a mix of implementation, scripting, testing, and technical coordination.

Your work will include implementing and maintaining decision rules, calculations, variables, and logic blocks in the credit engine. You’ll translate credit policy changes into structured technical logic and ensure naming conventions, configuration standards and architecture principles are followed.

A key part of the role is JavaScript development within the engine. You’ll write, debug and optimise scripts, handle transformations and calculations, and troubleshoot issues related to variable resolution, data structures and flow behaviour.

You’ll also contribute to testing and quality assurance. This includes preparing test payloads (JSON/XML), supporting automated tests (Java or JavaScript), comparing expected and actual responses, and helping improve how we structure regression and smoke testing.

When issues arise, you’ll assist in root-cause analysis – analysing engine logs, input/output differences, API responses and bureau data. You’ll work closely with IT and Credit Managers to reproduce issues and refine logic.

Beyond implementation, you’ll help structure how we work: documenting rules and flows, supporting release documentation, maintaining configuration hygiene, and contributing to frameworks for testing and implementation.
