• Partnering closely with the Director of Software, Product, and Engineering Leads to translate business requirements into scalable technical solutions
• Leading on system design and technical decision‑making across backend services, APIs, and cloud infrastructure
• Remaining hands‑on in code, setting the standard for clean, maintainable, well‑tested software
• Supporting and mentoring senior engineers, contributing to a culture of continuous improvement and high engineering standards
• Helping to modernise legacy elements while ensuring platform stability, resilience, and scalability

Technology Environment

• Backend: Go, Python, TypeScript, some .NET
• Frontend: React.js
• Engineering Practices: CI/CD, automated testing, observability, performance optimisation
• Architecture: Distributed systems, scalable SaaS platforms, fintech or regulated environments (beneficial)

What We’re Looking For

• Proven experience operating at Staff / Principal / Lead Engineer level within a SaaS environment
• Strong background in designing and building large‑scale, production‑grade systems
• Deep understanding of backend engineering, with experience across modern languages such as Go, Python, or TypeScript
• Comfortable working across multiple languages and paradigms, including some exposure to .NET
