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.

Qualifications
Required
  • Experience: 8+ years of professional experience building full-stack, user-facing web applications, including ownership of production services.
  • Front-End: Strong hands-on experience with React in production environments; advanced proficiency in JavaScript, TypeScript, HTML5, and CSS3.
  • Back-End & APIs: Experience designing and implementing UI-focused back-end services (Node.js, Python, PHP, or similar) using REST and/or GraphQL.
  • Databases: Strong experience with relational (PostgreSQL, MySQL) and time series databases (Prometheus).
  • Cloud & DevOps: Experience working in cloud environments with containerization and orchestration.
  • UX Collaboration: Experience working closely with UX teams and implementing designs from Figma or similar design tools.
  • Accessibility: Strong understanding of responsive design, accessibility standards, and browser compatibility.
  • Tooling & Testing: Solid experience with Git, GitLab CI/CD, and modern automated testing frameworks.
  • Debugging: Strong debugging and troubleshooting skills across front-end, API, and data layers.
  • Ability to work effectively in a collaborative, in-office engineering environment.

Preferred
  • Experience with the Laravel framework in PHP.
  • Familiarity with identity/auth platforms and API security patterns.
  • Background in storage, infrastructure, or data-intensive/enterprise-scale systems.

Education

Soft Skills
  • Strong technical leadership and problem-solving skills.
  • Clear and effective communication with both technical and non-technical stakeholders.
  • High attention to detail and a strong commitment to code quality.
