QA Lead – Core Ledgers

We are looking for an experienced QA Lead to own quality assurance for our Core Ledger platform. Our team does not develop the core ledger systems ourselves — they are built and delivered by external suppliers. Your role is to set the test strategy, verify and regression test what our suppliers deliver, and make sure nothing goes live unless it meets our requirements. Since the systems involved are financial, precision and thoroughness really matter — you will be the last line of defence before a delivery is approved.

This is a newly established, hands-on position within a small team. In this initial phase, the role will not carry direct reports; instead, the focus will be on personally executing tests, developing the test strategy, and leading verification and regression testing efforts in close collaboration with the wider team.

Key Responsibilities

• Define and own the overall test strategy for the Core Ledger domain, covering functional, regression, integration, and acceptance testing of supplier deliveries

• Personally build and maintain test plans, test cases, and (where applicable) automated regression suites

• Work with the Head of Core Ledger IT, Core Ledger Specialists, and Product Manager to embed quality from requirements through to delivery approval

• Verify and regression test ledger transaction flows, balance calculations, and reconciliation logic delivered by suppliers

• Drive a quality mindset across requirements writing, ensuring testability is considered from the start

• Investigate and triage defects, coordinating resolution with suppliers and internal stakeholders

• Define and track quality metrics; report on test coverage, defect trends, and delivery readiness

• Participate in go/no-go decisions for supplier deliveries based on quality criteria

• Support internal teams with questions about test results, known issues, and quality status

• Contribute to risk assessments for major platform changes or new product introductions

Desired Skills

• 5+ years in QA roles, with experience leading test strategy and acceptance testing for complex systems

• Strong experience with test automation tools and frameworks (e.g. Selenium, Cypress, RestAssured, Playwright or similar tooling)

• Deep knowledge of testing methodologies — functional, regression, integration, and acceptance testing

• Experience verifying and accepting deliveries from external suppliers or vendors

• Solid understanding of how to structure test plans and test cases against detailed requirements

Nice to Have

• Experience testing financial systems — ledgers, payment flows, reconciliation, or core banking

• Knowledge of performance and load testing tools (e.g. Gatling, k6, JMeter)

• Experience working with vendor or supplier delivery models

• Experience in a regulated financial or payments environment

Behaviours

• Quality champion — passionate about getting things right, not just fast

• Detail-oriented and methodical, especially in high-stakes financial contexts

• Strong communicator who can articulate quality risks to both technical and business audiences

• Proactive and self-driven — able to identify gaps and take initiative to address them independently

• Collaborative, working closely with a small team and external suppliers

Education
Bsc in Computer Science, Software Engineering, or related field. An ISTQB certification (or similar) is a plus.

Languages
Fluent English is required for this role. Fluent Swedish is not a hard requirement, but is desirable as Swedish is the language spoken locally in the team and will make day-to-day collaboration easier.

• A key role in building and shaping a modern, cloud-native core ledger platform

• A collaborative, cross-functional team environment with short decision paths

• Competitive salary and benefits package

• Flexible working arrangements with hybrid options

• Opportunities for professional development and continuous learning

• A chance to make a real impact in the fintech space across the Nordic market

• Modern office in central Borås with a strong team culture
