On behalf of a partner company, Nordic Investin is looking for a Senior Android Engineer Kotlin. You want to build an Android product that feels fast, dependable and native because the engineering underneath is disciplined. You will lead technical choices in Kotlin, improve architecture and delivery quality, and help the team turn complex service interactions into a calm mobile experience. Technical choices are expected to be explained in terms of maintainability, reliability and the people who use the product. Decisions should be recorded clearly enough that another engineer can understand the tradeoff months later. As a senior colleague, you will own substantial outcomes and help others make stronger decisions. You are expected to recognise risk early, communicate it without drama and move work forward with practical alternatives. What you will do

Develop native Android features with Kotlin and Jetpack Compose. Evolve modular architecture, dependency management and state handling. Integrate secure APIs, authentication and offline behaviour. Improve startup time, responsiveness and crash free usage. Build automated tests and reliable release pipelines. Coach peers through reviews and practical mobile engineering standards. What you will bring

Several years of native Android development in production. Advanced Kotlin and Android SDK knowledge. Experience with Compose, coroutines and modern architecture patterns. Testing experience across unit, integration and UI layers. Professional English; Swedish may be required by specific partners. Experience that would add value

Kotlin Multiplatform. Apps with high security or accessibility requirements. Mobile observability and experimentation platforms. A background that can succeed here

Your background may be in consumer apps, banking, mobility, commerce or public services. You have lived with the consequences of mobile releases and understand that maintainability, telemetry and graceful failure are part of the user experience. What makes the opportunity interesting

The partner needs a senior engineer who can shape the Android foundation and still enjoy shipping features. You will have clear ownership, a modern stack and the chance to make technical quality visible in the product. Nordic Investin will make sure you understand the context, expectations and decision path before you are asked to commit significant time. You do not need every optional technology if your core experience transfers and you can explain how you would close the gap. Nordic Investin welcomes candidates with different routes into technology and assesses applicants on relevant capability, judgement and potential.
