About Shelly

We make smart devices and push the boundaries of the IoT sector every single day. Shelly is a strong company with a startup mindset — no bureaucracy, just bold ideas, creative problem-solving, and a team that genuinely loves what they do.

We turn every spark of an idea into a real product — from first concept to full production — and bring smart automation to over 3 million households around the world. From heating, lighting, appliances, curtains, and more — if it runs on electricity, chances are we can automate it. We’ve built over 100 smart devices (and counting!), and everything happens right here at our headquarters in Sofia.

Senior Embedded Android Developer

Your Role:

You join as the Senior Android Developer driving the software for our Embedded Android Products. Work on Android-based platform and system apps, turning product ideas into a fast, reliable, beautifully simple control experience. You partner with hardware, firmware, and UX to deliver rock-solid devices that customers love.

What makes you a great fit:

• You have 5+ years of hands-on experience shipping Android on apps or embedded devices (panels, kiosks, set-top boxes, in-wall displays).

• You are fluent in Java (vanilla Java) and build robust system apps/services, Content Providers, Broadcast Receivers, and background services.

• Practical know-how with JavaScript, XML and JSON very much a full requirement.

• Other Android related languages and technologies are a plus.

• You are comfortable with connectivity stacks (WiFi, Bluetooth) and local device communication; Matter experience is also a BIG PLUS.

• You optimise for performance and reliability (boot time, memory, threading).

• You build secure devices (permissions, SELinux basics, secure storage, signed OTA packages).

• You work in Git based workflows.

• You communicate clearly and enjoy cross-functional collaboration.

Your Responsibilities:

• Develop the Android platform for Shelly’s Wall Display end to end — from BSP bringup to system apps and UX.

• Design and develop core system applications and services in Java: launcher/home screen, settings, device control widgets, and local web UI.

Implement robust connectivity and local control (WiFi/Bluetooth; LAN/REST/Matter integrations) that works seamlessly with the Shelly ecosystem.

• Instrument logging, crash reporting, and telemetry; create automated tests to catch regressions early.

• Measure and improve performance — boot time, UI fluidity, memory footprint, and overall responsiveness.

• Uphold security and privacy best practices across the stack.

• Document architecture and decisions; review code and work closely with other engineers.
