Join our global force of 400+ innovators, blending the latest in tech with the greatest in soundtracking, from our Stockholm HQ to offices in London, New York, Los Angeles, Berlin, Paris, Oslo, and Seoul. We’re an industry leader with a startup mentality. We take what we do seriously, but we don’t take ourselves too seriously. Creating and collaborating to transform the sound of streaming, content, and culture. Come join us, and let the world feel your work

We're looking for a Senior Android Engineer to join Mobile Experience, the team behind the Epidemic Sound app.

Picture a creator on the metro who hears a song and needs the right track for the video they're editing, right now. That's who we build for. Our mobile users are mostly influencers and creators who work from their phones, and we build for how they use mobile, not to match what the web product does.

Why you'll love this team

• A small, cohesive team of seniors. Four engineers, two on Android and two on iOS. We keep process light, with retros and some refinement, and run the rest on trust and autonomy.

• We set our own direction. There's no fixed roadmap. We decide together what's worth building and spend our time on what creators will enjoy, like making it effortless to find the right track for a video or turn a track into a shorter edit.

• A high bar for quality. The app is mature, modular and has very little legacy, because senior engineers have looked after it the whole way. We keep it that way, so we spend our time building rather than paying down tech debt.

• Capable, low-ego colleagues. Strong opinions, loosely held. The best idea wins, whoever it comes from, we pair now and then and share what we learn openly.

• Music is fun. You get to build a product around one of the best things in the world, with colleagues who love it as much as you do.

Your key responsibilities include

• Own features end-to-end: spot opportunities, prototype fast, take the best ideas to production, then measure the impact and iterate.

• Build polished, custom UI in Jetpack Compose and sweat the details of look and feel, from waveforms to our design system components.

• Work on music and playback, the most technically demanding part of the app.

• Keep the app healthy for the long haul: architecture, performance, accessibility, OS updates, API deprecations and releases.

• Pitch in on our Kotlin backend-for-frontend, CI and developer tooling when the need arises.

• Use AI agents as a natural part of how you work with code and everything around it, and help the team find new ways to apply them.

• Share what you know through code review, pairing and clear writing.

Requirements

• 6+ years of professional Android development in Kotlin.

• Deep experience with Jetpack Compose, especially building complex, custom UI, and a good eye for design and polish.

• Solid command of Kotlin coroutines and Flow.

• Apps you've shipped and kept alive in production for years, including platform changes and API deprecations handled without breaking things for users.

• The ability to not only understand but also explain complex topics such as performance, accessibility and architecture.

• Hands-on experience with agentic engineering, using AI agents as a tool for working with code and everything around it, and ownership of the quality of what they produce.

• Initiative. Nobody will hand you tickets, so you need to be happy finding what needs doing and doing it.

It would also be music to our ears if you have

• Experience with audio and playback, ideally Media3 / ExoPlayer.

• Experience with Gradle and large, multi-module codebases.

• End-to-end ownership of shipped features, from deciding what to build through implementation, release, measurement and iteration.

• Worked with design systems.

• Built and maintained continuous integration (CI) workflows.

• Experience with Kotlin on the server in a production environment; we maintain our own backend-for-frontend.

• UX design experience in Figma or similar.

Our tech stack

Kotlin, Jetpack Compose, coroutines and Flow, Hilt, Media3 / ExoPlayer, Room and DataStore, Retrofit and OkHttp, Gradle with version catalogs, custom Android lint checks, and GitHub Actions.
