Full Stack Engineer, UK

The Opportunity

As a Fullstack Engineer at Voop, you’ll play a pivotal role in developing and scaling our platform across web and mobile. You’ll work closely with Nick Pasha-Gubbins (Co-Founder & CTO) on:

• Architectural decisions for the core Voop platform.
• Feature development across Voop for Care, Voop for Schools, and Voop for Parents.
• Frontend build-out of modern web applications and mobile apps for iOS and Android using React and Kotlin Multiplatform.
• Deployment, optimisation, and real-world testing during pilots and large-scale rollouts.

From day one, you’ll contribute to production code, shape product direction, and see the direct impact of your work through user outcomes and safeguarding results.

This is a great time to join an early stage company with strong market traction, backing and momentum to go big.

Key Responsibilities

• Develop and maintain Voop’s full stack platform, including real-time web apps, mobile apps, and backend services.
• Design and implement frontend experiences across web and mobile (React / React Native / Kotlin Multiplatform).
• Build and optimise backend services (Hono, Postgres, AWS, Kamailio) powering the Voop network.
• Work on systems for mobile network management, device control (MDM), and AI-driven safeguarding tools.
• Collaborate with the CTO and engineering team on architecture, scalability, and security.
• Ship fast, iterate quickly, and deliver measurable value to real users.
• Engage with end-users to understand their challenges and ensure our technology delivers real-world impact.

Current stack: Typescript, React / React Native, Kotlin Multiplatform, Hono, Postgres, Pulumi/SST, Docker, AWS, Kamailio.

About You

• You’re pragmatic, fast-moving, and technology-agnostic, focused on solving the right problems well.
• You have several years of experience as a senior engineer or technical lead building quality products in lean teams.
• You’re opinionated but collaborative, bringing scars from what hasn’t worked and empathy for working fast with others.
• You care about the craft: clean architecture, reliability, and great user experience.
• You take ownership from frontend to backend and DevOps, seeing features through end-to-end.
• You’re driven by impact: building tech that matters, not just code that works.

Bonus Points

• Experience with voice/SMS platforms (e.g. Twilio, SIP Trunks).
• Understanding of mobile network architecture or MDM frameworks.
• Strong knowledge of networking (Layer 3+) or secure communications.
• Passion for online safety, child protection, or social impact tech.
