<h3>ROLE PURPOSE</h3><h3>ROLE PURPOSE </h3><p>This role owns feature delivery end-to-end across <a href="https://himalayas.app/companies/iidentifii">iiDENTIFii</a>'s stack from backend services and the data layer through to the web interfaces our clients and internal teams use. You are responsible for designing, building, testing, and shipping features that meet the exacting quality, security, and performance standards of a biometric identity platform used by tier-1 financial institutions.</p><p>This is a hands-on engineering role operating at the intersection of backend architecture, API design, and front-end craft. You will work closely with product managers, mobile engineers, and QA teams across all stages of the development lifecycle; from requirements and architecture through to release and ongoing optimisation. You bring both technical depth and a high standard of craft: clean, maintainable code on both sides of the stack, thoughtful UX, rigorous testing, and a genuine interest in getting the details right.</p><p>Operating in a security-sensitive, compliance-heavy domain, you are expected to bring sound judgement to architecture decisions, stay current with the evolving web and cloud landscape, and contribute to a culture of technical excellence across the engineering team.</p><h3>ROLE TASKS AND RESPONSIBILITIES </h3><h3>ROLE TASKS &amp; RESPONSIBILITIES</h3><h3>Application Development &amp; Architecture</h3><ul> <li>Design and build scalable, reliable backend services and APIs, and the web front-ends that consume them, ensuring responsiveness, performance, and a seamless experience end-to-end</li> <li>Own features from concept through to implementation; scoping, architecture, build, test, and release across both server and client</li> <li>Architect, design, develop, and maintain RESTful APIs alongside the database schemas and datastores that back them</li> <li>Collaborate with cross-functional teams to define, refine, and implement new features that align with product strategy and client needs</li> <li>Identify and implement performance improvements on the server (query optimisation, caching, scalability) and in the browser (load time, responsiveness) that meaningfully enhance production reliability</li> <li>Stay current with backend and front-end trends, emerging technologies, and best practices — and bring relevant opportunities to the team proactively</li> </ul><h3>Engineering Standards &amp; Code Quality</h3><ul> <li>Write clean, efficient, and maintainable code in C# / ASP.NET on the backend and a modern JavaScript/TypeScript framework (React or Angular) on the front-end</li> <li>Apply SOLID principles and sound architectural patterns including microservices and event-driven design where appropriate to produce code that scales and survives production</li> <li>Implement authentication, authorisation, and API security in line with best practice and regulatory requirements</li> <li>Conduct thorough code reviews, providing construc
