Join Söderberg & Partners Heartpace AB, a Swedish product company building reliable, high-quality software for the European market. We’re looking for a QA Engineer (Manual + Automation) who enjoys moving fast, taking real ownership, and raising the quality bar through smart testing and scalable automation.

We’re not looking for someone to “run checklists.” We’re looking for someone who can build confidence in releases, ship quickly with integrity, and help us automate QA and workflows using AI.

What we offer

• Conduct API testing using Postman (and support API test automation where applicable).
• Identify, log, and track defects in Jira, with high-quality reproduction steps and clear severity/priority.
• Collaborate closely with developers, product managers, and designers to clarify requirements and ensure test coverage.
• Improve QA processes across the SDLC: faster feedback loops, fewer flaky tests, better release confidence.
• Use AI tools to accelerate test design, reduce repetitive work, and improve efficiency (while keeping quality and security intact).

We value

• High performance / results-first: measurable impact over activity.
• Entrepreneurial ownership: be the engine, not the passenger.
• Data-driven decisions + systems thinking: rigor, scalability, and continuous learning.
• Fast execution with integrity: speed and reliability.
• Continuous improvement: skills, mindset, and outcomes.

You’ll thrive here if you…

• Prefer short cycles: ship → measure → iterate.
• Can turn ambiguity into execution (and help others do the same).
• Care about outcomes over process theater.
• Enjoy improving systems, not just following them.

What we’re looking for

• 5+ years of experience in manual and automation QA for web applications.
• Strong hands-on automation experience, ideally Playwright (or similar modern framework).
• Experience setting up automation approaches/frameworks and building maintainable suites.
• Solid knowledge of Postman, TestRail, Jira, and Confluence.
• Strong understanding of SDLC, Agile/Scrum, and quality practices in modern product teams.
• Understanding of client-server architecture.
• Good web fundamentals: HTML, CSS, HTTP, Ajax, JSON.
• Strong analytical skills, attention to detail, and clear communication.
• English: Upper-Intermediate+ for collaboration and documentation.
• Language bonus:
  • Swedish is a strong plus (conversational/professional level or native).
  • Ukrainian/Russian is a plus for smoother communication with part of the team from Odessa, Ukraine.
• AI usage experience: practical experience using AI tools to automate or accelerate QA/workflows (we’ll support and compensate relevant subscriptions).

Interview process (3 steps)

1. Screening interview with the Recruiter.
2. Technical interview with the Tech Lead + live task.
3. Final approval interview with the CTO.

Why join us?

At Söderberg & Partners Heartpace AB, quality is not a gate at the end - it’s a system we build. You’ll have real ownership, autonomy, and support, plus the opportunity to improve how we ship through automation, AI, and strong engineering collaboration.
