Senior Full Stack UI Engineer

Key Responsibilities

Full-Stack Architecture & Development

• Design, architect, and develop modern web applications using React, TypeScript, and Vue.

• Build and maintain Backend-for-Frontend (BFF) and API services (REST and/or GraphQL) that aggregate, adapt, and optimize back-end data for UI consumption.

• Translate UI/UX requirements into efficient back-end data models, API contracts, and service boundaries.

• Define and evolve front-end and BFF architectures with a focus on performance, scalability, security, and maintainability.

Front-End & Design System Collaboration

• Collaborate with UX and product teams to translate Figma designs into high-quality, reusable UI components aligned with shared design systems and component libraries.

• Drive UI performance optimization, accessibility, and cross-browser compatibility.

• Contribute to and consume shared component libraries across React and Vue ecosystems.

Cloud Infrastructure & Reliability

• Architect and maintain back-end infrastructure in AWS (EC2, RDS, SQS, SES, ECR) and containerized environments (Docker, Kubernetes).

• Own and improve API performance through caching strategies, query optimization, and efficient data transformation.

• Respond to production incidents in a timely manner and contribute to observability, monitoring (Prometheus/Grafana), and reliability initiatives.

Back-End Security

• Integrate authentication and authorization using identity platforms such as Keycloak, including SSO and role-based access control.

• Build secure, maintainable server-side functionality and contribute to security tooling across UI and back-end layers.

Data Management

• Design, evolve, and optimize relational database schemas (PostgreSQL, MySQL) and caching layers (Redis) in support of UI-centric use cases.

• Ensure data consistency, integrity, and performance across services.

Technical Leadership

• Lead code reviews, establish best practices, and ensure consistent engineering standards across front-end and back-end layers.

• Mentor junior and mid-level engineers and contribute to raising the overall quality bar of the team.

• Participate actively in design reviews, sprint planning, and cross-team technical discussions.

Quality & Testing

• Proactively identify technical debt and lead refactoring or modernization efforts.

• Champion high code quality through thoughtful design, automated unit/integration/e2e testing, and CI/CD pipeline discipline.
