Senior Software Developer Java and Event Streaming

Nordic Investin is recruiting a Senior Software Developer Java and Event Streaming on behalf of one of our partner companies. You want technical choices, delivery and production behaviour to reinforce each other, even when the constraints are difficult.

The partner is strengthening its capability in event-driven software for high-volume business processes. You will connect Java, Spring Boot and Kafka while ensuring that PostgreSQL and contract testing receive appropriate discipline. The aim is practical progress that colleagues can use, leaders can evaluate and the organisation can sustain.

The environment rewards early questions, visible trade-offs and engineering discipline. Security and operability belong in the design.

How you will work

You will work with product, architecture, security, operations and domain colleagues. The partner values short feedback loops, evidence from real systems and direct communication.

This role calls for independent judgement and the ability to raise the quality around you. You are expected to make trade-offs visible, recognise when a decision needs wider expertise and move work forward without creating unnecessary process.

What you will do

Own the practical direction for event-driven software for high-volume business processes.

Translate goals and constraints into a clear approach for Java and Spring Boot.

Establish useful standards, routines or decision artefacts around Kafka.

Coordinate stakeholders and dependencies affecting PostgreSQL.

Use evidence and measurable outcomes to improve contract testing.

Strengthen knowledge sharing and sustainable ownership through Kubernetes.

What you will bring

Relevant experience delivering event-driven software for high-volume business processes in a demanding environment.

Strong working knowledge of Java and Spring Boot.

Practical experience applying Kafka and PostgreSQL.

Ability to assess priorities, risks and trade-offs involving contract testing.

Evidence of clear stakeholder communication and dependable end-to-end ownership.

Professional English and the judgement to work with sensitive or business-critical information.

Experience that would add value

Experience from financial services logistics and digital commerce.

Exposure to Kubernetes in a cross-functional or multi-team environment.

Swedish language skills or experience working across Nordic organisations.

A background that can succeed here

Your background may be product engineering, platform work, enterprise technology or consulting. What matters is technical depth connected to user and business consequences. Direct experience of event-driven software for high-volume business processes is valuable, while adjacent experience counts when it shows transferable judgement.

What makes the opportunity interesting

The role offers meaningful ownership and the opportunity to influence both the solution and the decisions around it. The focus on event-driven software for high-volume business processes gives the opportunity a clear mission and room to influence priorities and success measures.

The exact partner, employment model, compensation, start date and working arrangement will be explained openly during the process. Nordic Investin will make sure you understand the opportunity before asking you to make a decision.

The recruitment conversation

Nordic Investin will focus on decisions you have made: the context, alternatives, result and what you would change today. You will also have room to ask direct questions and test whether the role, mandate and partner environment are right for you.

Apply with your CV or LinkedIn profile and a short note about a relevant system, platform or technical change you helped improve. Nordic Investin welcomes different routes into the profession and assesses evidence, judgement and potential alongside formal titles.
