Medior Technical Tester (Backend, Test Automation, SQL)

We are looking for a Technical Tester to join our long-term partnership with ICA, one of Scandinavia's largest companies.

This is a full-time, on-site position in Sarajevo, with a start date as soon as possible.

The initial engagement is planned for a minimum of 17 months, until 28 February 2028, with the possibility of extension.

You will join Team Core Activebank within ICA Banken, working primarily with backend, API, integration, and database testing of business-critical banking systems.

This role requires strong hands-on test automation and backend testing experience, with the ability to contribute to automation from the start.

You will be part of Core Activebank, a team responsible for backend systems supporting ICA Banken and ICA Gruppen.

The team works with two key systems:

• Activebank – ICA Banken's core banking system
• IHB – an ICA Gruppen backend system maintained by the Core Activebank team

ICA's web and mobile applications are being modernized, introducing changes and new requirements across these backend systems. As part of the team, you will help ensure that these changes are thoroughly tested across APIs, backend services, databases, and integrations.

While testing activities cover multiple layers, the primary focus of this role is backend testing.

The work includes:

• Developing, maintaining, and executing automated tests
• Testing backend systems and APIs
• Testing integration layers, including contracts, data mappings, and error handling
• Performing database validation and troubleshooting using SQL
• Understanding system architecture and following data and requests across different system components
• Building and maintaining automated regression test coverage
• Investigating defects across APIs, backend services, databases, integrations, and data flows
• Integrating and running automated tests as part of CI/CD processes
• Combining automated and manual testing where appropriate
• Supporting testing throughout development, release, and production cycles
• Collaborating closely with developers, testers, and other team members in Bosnia and Herzegovina and Sweden
• Continuously improving test coverage, automation, and overall software quality

• 3–5 years of professional software testing experience
• Strong hands-on backend testing experience
• Strong hands-on test automation experience, with the ability to independently contribute to automated testing from the start
• Hands-on experience with Playwright or a comparable modern test automation framework
• Experience using a programming language for test automation, preferably TypeScript or C#
• Strong hands-on experience with API testing
• Strong SQL knowledge and practical experience validating and investigating data using SQL queries
• Experience testing integration layers, including contracts, data mapping, and error handling
• Good understanding of system architecture and how APIs, backend services, databases, and integrations interact
• Experience with CI/CD environments and automated test execution
• Good understanding of test automation frameworks and the principles behind them
• Experience investigating and troubleshooting issues across different system layers
• Solid understanding of software testing principles and test case design
• Strong analytical and problem-solving skills
• Strong communication and collaboration skills
• Ability and willingness to learn, investigate, and ask questions
• Ability to work independently while collaborating effectively within a team
• Good English communication skills

• Experience with C# for backend/API test automation
• Experience with RestSharp or similar API testing libraries
• Experience with performance testing, particularly LoadRunner or similar tools
• Experience with Azure DevOps
• Experience testing mobile applications
• Experience with BrowserStack or similar platforms
• Experience using AI tools in software testing
• Previous experience in banking, financial services, or insurance
• ISTQB Foundation or another relevant testing certification

This isn't a customer–supplier relationship. We operate as one team, one culture, side by side.

• Single client focus - No context-switching. Go deep, build expertise, see impact over time.
• On-site in Sarajevo - Work from our dedicated office alongside your team.

• Knowledge transfer - Learn directly from ICA's engineering teams in Sweden.
• Access to ICA's learning hub - Internal training platform with mandatory and optional courses.
• Travel to Sweden - 5-day onboarding trip plus ongoing workshops with Swedish colleagues.

• Five weeks off - 26 days of paid vacation. Swedish standard.
• Flexible hours - Working hours and lunch breaks are flexible within the same time frame.
• Religious & personal flexibility - 5 additional days for religious and personal observances.

• Private health insurance - Comprehensive private coverage.

*This is a dedicated long-term partnership with its own structure and benefits. These conditions apply to this opportunity and may differ from standard Zendev benefits.

1. Initial contact - You'll receive full details upfront. No surprises.
2. Pre-screening - Short conversation about your background.
3. Interview with ICA - Meet the Swedish team directly.
4. Check & offer - Background verification, then a clear offer.
5. Onboarding - Local setup + travel to Sweden for team integration.

ICA is Sweden's largest retailer, headquartered in Solna, Stockholm. The company operates grocery stores, ICA Bank, ICA Insurance, Apotek Hjärtat pharmacies, and a nationwide logistics network. ICA has been part of Swedish daily life for over a century.

Zendev is a Swedish-Bosnian software company. We provide engineering services to clients across Europe, with a focus on Scandinavia. We're built on long-term partnerships, not transactional relationships.

If this sounds like something you'd enjoy, we'd like to hear from you.

Our developers already work daily with ICA's teams in Sweden. We understand the questions you might have:

• What's it like working with a Nordic partner?
• How does collaboration between Sarajevo and Sweden actually work?
• What should I expect in my first months?

That's exactly why we're here.
