Senior Full Stack Engineer

About the Role : - We are rebuilding our public-facing web platform on a modern, headless architecture. You will design and build the content layer (Strapi) and the React front end that consumes it. The work is performance-sensitive, security-conscious and subject to regulatory and compliance requirements. You will be a hands-on senior engineer who shapes technical decisions and mentors others.

Key Responsibilities:

• Design, build and maintain scalable web applications using React.js (Next.js preferred) and Node.js.
• Architect and implement content models, APIs and workflows in Strapi headless CMS (Contentful, Sanity, Directus, Payload, etc.).
• Build custom Strapi plugins, controllers, services, lifecycle hooks, middleware and policies, and handle upgrades across major versions.
• Configure roles and permissions, i18n, media handling, and draft/publish and review workflows to meet editorial and compliance needs.
• Build REST and GraphQL APIs and integrate the CMS with internal services, third-party APIs and authentication systems (SSO/SAML/OAuth2).
• Optimize for performance, SEO and accessibility (Core Web Vitals, SSR/SSG/ISR, caching, CDN).
• Write clean, tested, maintainable code, and take part in code reviews and architecture discussions.
• Own deployments with the DevOps team: CI/CD, containerization, environment management and monitoring.
• Apply secure coding practices (OWASP Top 10, input validation, secrets management, dependency hygiene) and support security reviews and audits.
• Mentor junior and mid-level engineers, and document technical designs and decisions

Required Skills and Experience :

• 6 to 9 years of professional software development, including 4+ years of strong hands-on Node.js (Express, NestJS or Koa) and React.js.
• Proficiency in JavaScript (ES6+) and TypeScript
• At least 2 years of hands-on experience with a headless CMS, preferably Strapi (v4/v5), covering content modeling, custom extensions and production deployment.
• Solid understanding of REST and GraphQL API design.
• Experience with relational databases (PostgreSQL, MySQL), including schema design and query optimization.
• Experience with state management (Redux, Zustand or React Query) and modern React patterns (hooks, context, code splitting).
• Familiarity with Git workflows, CI/CD pipelines, Docker, and at least one cloud platform (AWS).
• Experience writing unit, integration and end-to-end tests (Jest, React Testing Library, Cypress or Playwright).
• Good understanding of web security, authentication and authorization.
• Strong communication skills and the ability to work with product, design, content and compliance stakeholders.
• Experience in BFSI, fintech or other regulated industries, including audit trails, maker checker approval flows and data-privacy requirements.
• Familiarity with SSO integrations (Okta, Azure AD) and role-based access control at scale.
• Contributions to open-source projects, or authored Strapi plugins.
