Android Engineer

We’re looking for a Mid-Level Android Engineer to join our small, experienced team. We want someone who is product-oriented and cares about how people will use and interact with the software they're building.

You will play a crucial role in shaping the future of mobile at Yoto, with ample opportunities to influence our direction and growth. We are looking for engineers who prioritise quality while thriving in a fast‑paced environment.

About Yoto

Yoto is a screen‑free interactive audio platform for kids. We make carefully connected audio players that kids control, with no microphones, cameras or ads. We have a catalogue of audio that inspires creative play and learning with 1,000+ titles in our card store from top creators, publishers and labels – think Disney, Marvel, Roald Dahl and Universal Music. We also create Yoto Originals like BrainBots.

• Voted the 14th fastest-growing private software technology company in Britain in The Sunday Times 100 Tech 2025; and named the 94th fastest-growing company in Europe in the prestigious FT1000.
• Ranked 9th in Fast Company's Most Innovative Companies in 2024; and featured in the Sifted 100 fastest-growing startups across the UK & I by revenue growth.
• Featured in Bloomberg’s 25 UK startups to watch in 2023; and ranked second fastest growing tech company in the UK in the Deloitte Fast50.
• Named one of TIME Magazine’s Top 100 Inventions of 2020.
• We’re over 200 employees spread across the world… and growing!

We’re on a mission to be the soundtrack of childhood, and help families on their own unique adventures. By creating products that inspire independent play, we help families discover and grow with an inspiring world of audio – and we would like you to help us achieve it!

Android at Yoto

Our Android team is now made up of 4 developers working across either the Core App, Player Experience or Content Discovery teams. The app is designed to support parents giving them access to their whole content library, enable them to make their own content, set player settings & remote control the Yoto player, play content on their phone and in the car via Android Auto, and purchase more content via our Discover hub in the app.

Our codebase is entirely in Kotlin, and most of our UI is now in Jetpack Compose. We are constantly looking for ways to improve and modernise the codebase. We use Okhttp and Retrofit for our networking, Exoplayer for playback, Moshi, Paho MQTT for interfacing with the Yoto Players, Auth0 for authentication, Firebase, Braze and Bugfender.

Our user base is expanding rapidly, and we aim to grow the team sustainably to scale our codebase and support new features while refining existing work. We are particularly committed to improving performance and stability, as evidenced by our excellent crash‑free rate and App Store reviews.

We dedicate 10% of our time as a Learning Day – time set aside to learn, experiment, and grow.

What you’ll be doing

• Build and ship new features and improvements for the native Android app.
• Collaborate closely with product managers, designers, and other engineers to deliver exceptional user experiences.
• Participate in code reviews, testing, and iterative improvements to maintain a high‑quality and scalable codebase as we grow.
• Work in close collaboration with the iOS team to develop features together.
• Contribute new ideas and engage in discussions regarding architecture, standards, and tooling.

What you’ll bring

• You are passionate about building a team, not just being a part of one. You are willing to invest extra time to explain concepts, provide constructive feedback, and elevate those around you.
• You possess strong communication skills, both verbal and written.
• You have proven years of experience in Android app development within a fast‑paced environment.
• You have native Android Kotlin development experience.
• You understand Kotlin app development design patterns and native Android SDKs.
• You understand patterns such as MVVM.
• You have experience consuming third‑party APIs and are familiar with standard authentication mechanisms (OAuth/Auth0).

Bonus Points

• Experience with playback systems.
• A keen eye for detail and UI polish.
• Expertise in performance optimisation.
• Experience with e‑commerce platforms.
• Experience with popular IoT protocols (RFID/NFC, Bluetooth/BLE, WiFi, MQTT)
• Android Auto

Salary: £60,000 based on experience
