ZigZag is the #1 app for dog training & life skills, helping pups and their pawrents build a lifelong bond. Our mission is to prevent behavioural issues or abandonment by making puppy training accessible and enjoyable for everyone.
Our engineers build and maintain the ZigZag Puppy Training mobile app (iOS and Android), with meaningful work across the full stack, particularly focusing 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 will work across the full stack, contributing to both backend services and the mobile app. As a senior engineer, you will help guide backend and infrastructure design decisions and best practices, with scope to grow into broader technical leadership over time.
We work collaboratively through pair programming, peer review, and regular learning sessions, partnering closely with product and design to ship high-quality features at pace.
What You’ll Do
- Design and ship features across the full stack, writing high-quality, maintainable code
- Take a leading role in backend design, data modelling, and API quality, ensuring the platform scales safely and reliably
- Feed into decisions around infrastructure and CI/CD, contributing to improvements in our Azure-hosted pipelines
- Work closely with the Head of Engineering, product, and design to plan and deliver roadmap initiatives
- Ensure our code meets security, privacy, and performance best practices
- Share knowledge with teammates through collaboration, mentoring, and code review
- Take part in interviews and pairing sessions to help us build a strong, inclusive engineering team
What You’ll Bring
This role is ideal for a full-stack engineer who enjoys working across the stack and brings particular strength and experience on the backend.
Core capabilities
- Experience delivering production features across a modern web or mobile stack
- Depth of experience in backend development, including APIs, data modelling, and system design
- Comfort moving between backend and frontend codebases in a collaborative team
- A pragmatic approach to reliability, performance, and security
- Clear communication skills and a learning mindset
Helpful experience (not required):
- Experience with modern UI frameworks such as Angular, React, or Vue
- Exposure to CI/CD pipelines and cloud platforms (Azure, AWS, or GCP)
- Experience with mobile, hybrid, or cross-platform app development
- A passion for dogs is optional but highly appreciated!
We know no one meets every requirement perfectly. If you’re excited about our mission and feel you could grow into this role, we encourage you to apply.
