Job description

Job Description:

This position leads React.js application development and support through hands‑on engineering, architectural ownership, code quality, mentorship, and cross‑functional collaboration with product, UX, backend specialists, and clients to deliver secure, accessible, scalable, high‑performance applications.

You will own technical decisions and production readiness through spec‑driven development (SDD) and responsible AI‑assisted delivery. You will independently implement, review, test, debug, and correct human‑and‑AI‑generated code. Experience with AI tools is preferred, not mandatory.

Responsibilities:

• Lead React architecture and development; assess API, backend, and data dependencies, explain trade‑offs, and align implementation with the existing architecture
• Enforce coding standards, design patterns, and pragmatic SOLID, DRY, KISS, and Clean Code practices
• Own frontend performance, security, accessibility (WCAG), scalability, and production‑readiness checks
• Plan React and framework upgrades, including compatibility checks, testing, and rollout
• Lead SDD with product, business analysis, UX, and engineering: clarify requirements, measurable acceptance criteria, edge cases, and non‑functional needs; review plans and tasks, follow approval gates, and align specifications, code, and tests
• Build reusable, responsive, mobile‑first, cross‑browser React interfaces from UI/UX designs
• Debug browser, API, service, and deployment issues using logs, traces, and reproducible tests; validate AI‑proposed fixes and make targeted corrections
• Ensure unit, component, integration, and end‑to‑end tests cover acceptance criteria, negative paths, authorization, and non‑functional needs; independently verify generated assertions and enforce CI/CD quality and security checks before merge
• Coordinate cross‑functional delivery, dependencies, and risks; seek specialist review beyond personal expertise
• Engage clients on requirements, technical decisions, delivery trade‑offs, technical discussions, and issue resolution
• Review human‑and‑AI‑generated changes for business logic, specification alignment, security, maintainability, dependencies, and test adequacy; approve only explainable, validated changes and provide actionable feedback
• Guide approved AI workflows with repository context, constraints, and reviewable increments; protect confidential data and credentials, respect agent permissions, and mentor developers in SDD, validation, and continuous improvement

As a Tech Lead, your additional responsibilities will be:

• Serve as the React.js expert for the team
• Establish code‑review practices across the team
• Drive knowledge sharing across the frontend team
• Stay current with frontend technologies and industry best practices

Technical Qualifications:

• Experience in REST API integration and review, covering contracts, validation, authentication, authorization, business rules, and error handling, with practical Node.js/TypeScript or equivalent backend capability to trace issues and make targeted corrections
• Expertise in React.js, including functional components, hooks, context, and performance optimization; strong TypeScript, JavaScript (ES6+), HTML5, CSS, and modern styling skills
• Experience with Jest/Vitest, React Testing Library, and integration/end‑to‑end equivalents, with the ability to assess test quality beyond passing results
• Experience with Redux, Zustand, or equivalent state management, and sound component and application design
• Experience in accessible, responsive, mobile‑first, cross‑browser development
• Experience with Git, focused pull requests, and peer review, including versioning specifications and implementation artifacts and linking code and tests to acceptance criteria
• Experience in technical leadership across architecture, reviews, mentoring, and cross‑stack delivery coordination
• Experience in specification‑based delivery using acceptance criteria, plans, and review gates, and in Agile/Scrum with Jira or equivalent tools
• Experience in logging and frontend monitoring with Sentry, Application Insights, Datadog, or equivalent tools for production troubleshooting
• Understanding of CI/CD, environment configuration, secrets, deployment validation, and rollback; familiarity with micro‑frontends and cloud‑hosted frontend deployment on AWS, Azure, or GCP is a plus
• Knowledge of npm/Yarn, Vite/Webpack, linting, and dependency management
• Working knowledge of SQL and relational databases, including relationships, constraints, transactions, indexes, and migrations; ability to review queries and data access for integrity, performance, and safe parameters, seeking specialist support when needed
• Familiarity with Next.js or a similar React framework is a plus; familiarity with Angular, Vue.js, or other JavaScript frameworks is desirable
• Familiarity with AI‑assisted coding, testing, and documentation using GitHub Copilot, Cursor, Claude Code, or equivalent tools is preferred, including providing context and guardrails, challenging output, correcting generated code, and following approved‑tool, confidentiality, credential, dependency, and agent‑permission policies; Spec Kit or equivalent SDD tooling is desirable

Personal Skills:

• Translate business needs into practical solutions; identify ambiguities, missing acceptance criteria, edge cases, and unsupported assumptions
• Evaluate alternatives and challenge AI recommendations using engineering principles and validation evidence
• Explain technical details, decisions, risks, and trade‑offs clearly in spoken and written English to technical and non‑technical stakeholders
• Learn quickly, take ownership, mentor constructively, and manage competing priorities independently and collaboratively

Education and Work Experience:

• CS, IT, or related scientific background preferred
• Over 8 years of relevant experience or equivalent education and experience, with React delivery and technical leadership. Demonstrate architectural judgment, debugging, correction of unfamiliar/generated code, and acceptance‑criteria validation through project evidence or a practical exercise
