About the Role

We are seeking a motivated Senior Full Stack Engineer with a front-end focus to join our Health Alliance team, which plays a critical role in the monetisation strategy and driving our mission to scale TrustedHousesitters from 250K to 1 million members.

• Strong understanding of scalable web architecture, performance optimisation, and secure coding practices
• Experience designing, building, and evolving APIs and integrating with third-party platforms
• Hands-on experience with Next.js, SSR/SSG strategies, and Core Web Vitals optimisation
• Solid foundation in HTML, CSS, and accessibility best practices
• Ability to lead technical discovery, architecture planning, and implementation of complex product features
• Excellent communication skills and confidence in collaborating cross-functionally with Product Managers, Designers, and non-technical stakeholders
• Comfortable driving initiatives in ambiguous problem spaces, aligning business and technical perspectives
• Experience mentoring engineers through pairing, code reviews, and knowledge-sharing
• Familiarity with CI/CD pipelines, automated testing strategies, and observability tools (e.g., GitHub Actions, Sentry, Datadog)
• A mindset geared toward experimentation, measurement, and continuous improvement, especially within growth-driven product teams

Nice to Have

• Previous experience working in a start-up/scale-up environment
• Familiar with Agile methodologies and working with Scrum/Kanban
• Exposure to the payment domain and payment processors (e.g. Stripe)
• Curiosity for React Native and app development
• Experience leveraging AI to enhance your own productivity
• Familiarity with A/B testing frameworks or data-informed experimentation
