• Design, develop, and maintain responsive, performant, and accessible web applications across the full stack from UI to API to database.
• Build and iterate on front-end experiences using React (Vite), TypeScript, JavaScript, and HTML/CSS, adhering to modern design principles and component-driven architecture.
• Develop and maintain robust back-end services and APIs using C# and NET Core, ensuring scalability, reliability, and security.
• Collaborate with Product, UX, and PMO teams to translate requirements and design specifications into production-ready features.
• Own and execute deployments to AWS cloud infrastructure, leveraging CI/CD pipelines to ensure fast, reliable, and repeatable releases.
• Troubleshoot and resolve cross-stack bugs and performance bottlenecks, proactively identifying root causes and driving lasting fixes.
• Participate in code reviews, providing constructive feedback and upholding engineering standards across the team.
• Contribute to technical design discussions, architectural decisions, and sprint planning sessions.
• Document code, APIs, and deployment processes to support team knowledge-sharing and operational continuity.
• Support and mentor mid-level developers, fostering a culture of quality and continuous improvement.

Requirements:

• 6-9 years of overall software development experience, with a strong track record of delivering end-to-end web applications in a production environment.
• Front-end expertise: Proficiency in React (with Vite), TypeScript, JavaScript, HTML, and CSS, including responsive design, component libraries, and state management patterns.
• Back-end expertise: Strong hands-on experience with C# and NET Core, including RESTful API design, middleware, dependency injection, and service integration.
• Node.js : Working knowledge of Node.js for tooling, middleware, or server-side scripting within the application stack.
• Cloud deployment (AWS): Practical experience deploying and maintaining applications on AWS (e. g., EC2 S3 Lambda, RDS, CloudFront, or equivalent services).
• CI/CD pipelines: Experience building or working with continuous integration and delivery pipelines (e. g., GitHub Actions, Azure DevOps, Jenkins, or AWS CodePipeline).
• AI-assisted development: Practical experience using Gen AI coding tools such as Cursor, GitHub Copilot, or Claude to accelerate development workflows including code generation, refactoring, debugging assistance, and documentation. Able to critically evaluate AI-generated output for correctness, security, and maintainability before integrating it into production code.
• Design principles: Strong grasp of responsive design, accessibility standards, and UI/UX best practices, able to work from design systems or Figma/XD specifications.
• Cross-stack debugging: Demonstrated ability to diagnose and resolve complex bugs spanning front-end, back-end, and infrastructure layers.
• Collaboration under pressure: Comfortable working in fast-paced, agile environments alongside Engineering, Product/UX, and PMO stakeholders, able to manage competing priorities without sacrificing quality.
• Agile/Scrum: Experience working in sprint-based delivery teams with regular standups, retrospectives, and iterative releases.
• SQL and relational databases: Solid foundational SQL skills with working knowledge of SQL Server and PostgreSQL, including writing queries, joins, stored procedures, and basic schema understanding to support debugging, data validation, and integration troubleshooting.

Nice to Have:

• Experience with Cloudflare CDN configuration, caching strategies, or edge security rules.
• Familiarity with CMS integration (e. g. Crownpeak, Contentful, or similar headless CMS platforms).
• Exposure to micro-frontend architectures or module federation patterns.
• Knowledge of containerisation using Docker and orchestration with Kubernetes or AWS ECS.
• Experience with monitoring and observability tools such as Datadog, New Relic, or AWS CloudWatch.
• Understanding of web performance optimisation, including Core Web Vitals (LCP, INP, CLS).
• Familiarity with GraphQL or event-driven architectures (e. g., AWS SQS, SNS, or Kafka).

Key Soft Skills:

• Thrives under pressure: Calm and effective when navigating tight deadlines, production issues, or rapidly shifting priorities.
• Problem-solving mindset: Approaches complex technical challenges systematically, breaking down ambiguity and driving to resolution.
• Cross-functional communicator: Able to engage credibly with Engineering peers, Product owners, UX designers, and project managers, translating technical concepts clearly for non-technical audiences.
• Ownership and accountability: Takes responsibility for end-to-end delivery, from initial design to post-deployment stability.
• Continuous learner: Stays current with evolving front-end and back-end technologies and proactively applies new techniques to improve the codebase.
• Tech Stack at a Glance: React (Vite), TypeScript / JavaScript, HTML / CSS, Node.js, C# /. NET Core, AWS, CI/CD Pipelines, SQL Server, PostgreSQL.
