Job description

About Reqtest

Reqtest is the leading Nordic SaaS platform for quality assurance in digitalisation projects. We're a small, focused team with high ambitions and strong commitment. Our 200 customers in Sweden and abroad include well-known brands such as Lantmännen, Scania and Philips Healthcare. We already have a product our customers love: 4.5 out of 5 on Capterra, and customers stay with us for 8 years on average. But we still see big opportunities to make it even better. Our vision is to help our customers succeed with their digitalisation by taking control, working in a structured way and collaborating successfully in their digitalisation projects.

Reqtest is part of the Nordtech Group, which acquires and develops successful tech companies. Reqtest is entering its most important phase yet: moving development in-house and rebuilding the product around AI.

About the role

As a full-stack developer at Reqtest, you build features end to end, from front end to back end. You build new functionality, including generative AI features and integrations, and improve what's already there, with a focus on quality and value for the customer.

You're part of the dev team, report to our CPO and collaborate closely with both the CPO and our CTO. We're a small company with a flat organisation, so you're close to everyone and see the impact of what you build.

You'll work agent-driven, where agents do much of the work and you direct, review and own the result. You follow your features all the way, from understanding the need, sometimes in meetings with customers, through technical decisions, implementation and testing, to release and follow-up. You'll also help us make the move to an AI-native way of working and shape what it looks like.

In short, you will be working with:

• building features end to end, front end (Angular, TypeScript) and back end (.NET/C#)
• developing generative AI features in the product
• building and maintaining integrations with other systems
• securing quality through code reviews, test automation and E2E tests in a continuous deployment setup
• making technical and architectural decisions together with the CPO and CTO
• turning needs into technical solutions, working closely with the product, operations and customer teams
• using AI tools as a natural part of the development workflow, not just as an add-on

To succeed in this role, we believe you have

• 5+ yeas as a full-stack developer within .NET/C', Angular and TypeScript.
• Hands-on experience of agent-driven development, including setting up agents and basic AI infrastructure.
• Experience shipping generative AI features to production.
• Experience of test automation, from unit to E2E, and continuous deployment.
• Experience building integrations via REST APIs.
• Fluent English.

Nice to have

• Experience of Workato or another iPaaS.
• UX/UI skills.
• A clear product mindset and experience of SaaS environments.
• Experience of introducing new ways of working or technologies in a team.
• Experience of SQL Server, CQRS, and performance and optimisation.
• Swedish language skills.

Your style

You're curious about more than the code – you want to understand the product and the customers who use it, and you're comfortable joining a customer meeting when it helps. You don't wait for a detailed spec: you take a problem, ask the right questions and find a solution. You thrive with a lot of responsibility and freedom.

You keep up with AI because you want to, not because you have to – you try new tools and models, share what works and like to prototype before deciding. You're not afraid to have an opinion, but you listen before you decide – and you're happy to let the best idea win.

Your time at Reqtest

• Real influence over the product, the tech and our move to an AI-native way of working
• Short decision paths and close contact with customers
• Modern offices at Convendum, Gävlegatan 16 in Vasastan, Stockholm. We're on site about 4 days a week, because that's where the culture is built, with flexible hours
• Breakfast, gym and a good work environment

We interview on an ongoing basis. The process:

1. Screening call with our recruitment partner
2. First interview: competencies and soft skills
3. Alva Labs tests
4. Tech interview/case: about 2-3 hours of independent prep work, then you present your solution to us
5. References and background check
6. Offer

We want to get to know you properly, and we hope you want to get to know us :)
