Job description

Lead the end-to-end technical design and development of full-stack applications, with emphasis on the front-end/UI platform and its supporting APIs.
Own the micro-frontend (MFE) strategy - module boundaries, shared shell, and Webpack & Module Federation setup across teams.
Define the UI design system - component libraries, design tokens, and how they’re sourced from Figma and propagated to code.
Set standards for state management across React applications and for CSS architecture at scale.
Own accessibility (ARIA/WCAG) compliance delivery across all UI surfaces.
Define UI performance budgets and drive performance/error monitoring rollout in production.
Design, build, and manage robust RESTful APIs (OpenAPI 3.0) and service integrations, including versioning, lifecycle, and governance.
Set the strategy for contract testing across producing and consuming teams.
Direct authentication/authorization delivery using OAuth/OIDC and enforce OWASP security standards for both UI and APIs.
Design and optimize database queries, indexing, and data access strategies (schema/data modelling not required for this role).
Set the test automation strategy (Playwright) and quality gates for UI/API releases.
Ensure application scalability, availability, reliability, and security.
Collaborate with product, engineering, DevOps, and other stakeholders to translate business requirements into technical solutions.
Provide technical leadership, code reviews, and mentorship to development team members; run day-to-day delivery of the team including sprint commitments and real-time unblocking.
Drive engineering best practices including clean code, testing, CI/CD, monitoring, and documentation.
Champion effective use of AI-assisted development tools (e.g., GitHub Copilot) across the SDLC - coding, code review, testing, and documentation - and set adoption practices for the team.
Identify technical risks, bottlenecks, and architectural improvements and provide effective solutions.
Participate in effort estimation, sprint planning, technical roadmaps, and delivery planning.

Experience with state management patterns (Redux, Context, signals, or equivalent) and CSS architecture at scale.
Experience working with a UI design system (component libraries, design tokens) and Figma hand-off workflows.
Working knowledge of ARIA/accessibility (WCAG) standards.
Solid understanding of OAuth/OIDC and OWASP security practices for both front-end and APIs.
Experience writing contract tests for APIs.
Comfortable writing and optimizing SQL queries against relational databases (e.g., PostgreSQL, MySQL) - data modelling/schema design not required.
Experience with CI/CD pipelines, automated testing (Playwright or similar), and production deployment practices.
Practical, hands-on experience using AI-assisted coding tools (e.g., GitHub Copilot) in day-to-day development and across the SDLC.
Experience mentoring and guiding software engineers.
Strong problem-solving, communication, and stakeholder management skills., * Experience with Python for backend/API development (added advantage, not required) - frameworks such as FastAPI, Django, or Flask.
Working knowledge of AWS (compute, storage, database, networking, security, monitoring services) - preferred, not mandatory.
Experience with containerization and orchestration technologies such as Docker and Kubernetes.
Experience implementing UI A/B testing.
Exposure to error/performance monitoring tooling (DynaTrace RUM, or similar).
Experience working in Agile/Scrum development environments.
Prior work in a regulated or enterprise design-system environment.
