About the Role: We are looking for a Senior Full Stack Developer with 6–9 years of hands-on experience designing, building, and deploying responsive, end-to-end web applications. You will be a key contributor across our Engineering organization, collaborating closely with Product, UX, and Engineering teams to deliver high-quality digital experiences. You are someone who thrives under pressure, takes ownership of complex problems, and can navigate the full technology stack with confidence.

Key Responsibilities:

• 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.

Required Skills & Experience:

• 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 & 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 containerization 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 optimization, 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.
