Hybrid – preferably working from the office a couple of days per week - Stockholm

We are looking for a Senior Fullstack Developer to join a small and stable product team working with Pulse Engagement solutions for customers.

This is a great opportunity for someone who enjoys working broadly across the stack and taking significant ownership in a smaller team. The role is fullstack, with a clear backend focus, while you will also contribute to the frontend.

The team’s Engineering Manager has a strong background and deep expertise within AI, giving you a great opportunity to work closely with and learn more about how AI can be applied in modern product development.

The role

On the backend, the team primarily works with Kotlin. Strong previous experience with Java is also highly relevant, so extensive Kotlin experience is not necessarily required if you have a solid Java background and are comfortable moving into Kotlin.

On the frontend, the team works with React, and we are looking for someone who is comfortable contributing across both backend and frontend.

The team currently consists of two mobile developers and one backend developer. As a small team, everyone has a high level of ownership and the opportunity to influence both technical solutions and the overall product.

We are looking for someone with

• 5+ years of professional software development experience
• Strong experience with Kotlin and/or Java
• Experience with React
• Fullstack experience with a strong backend focus
• Ability to work independently and take ownership
• A pragmatic and solution-oriented mindset
• Strong communication and collaboration skills
• Experience working in smaller product teams, startups or scaleups is a strong plus

As a person, we believe you are driven, self-going and communicative. You enjoy working in smaller teams where you are expected to take initiative, solve problems and contribute beyond your immediate area of responsibility.
