Senior Software Engineer (Remote UK)
About ZigZag
ZigZag is the #1 app for dog training & life skills, helping pups and their pawrents build a lifelong bond. Too many dogs miss out on the right training, leading to behavioural issues or even abandonment. Our mission is to prevent that by making puppy training accessible and enjoyable for everyone.
We’ve been featured as Apple’s App of the Day, highlighted in New Apps We Love, and shortlisted for multiple industry awards. Backed by a major global petcare organisation, we’re a growing product-led company with big ambitions and a close-knit team.
About the Role
Our engineers build and maintain the ZigZag Puppy Training mobile app (iOS and Android), with meaningful work across the full stack, and particular responsibility for helping raise the bar on backend systems, APIs, and data-driven product development.
The app is built using Nest.js and TypeScript on the backend, with an Angular (v20) UI and Ionic for cross-platform mobile delivery. We deploy multiple times per day via CI/CD in Azure, enabling small, frequent releases and fast feedback.
This is a hands-on senior individual contributor role. You’ll work across the full stack, contributing to both backend services and the mobile app. As a senior engineer, you’ll also help guide backend and infrastructure design decisions and best practices. There’s scope to grow into broader technical leadership over time, if that’s something you’re interested in.
We work collaboratively through pair programming, peer review, and regular learning sessions, and partner closely with product and design to ship high-quality features at pace.
