Specialist Frontend Engineer

• Build & evolve the frontend: implement features in React/TypeScript; shape component architecture, routing, data fetching, and state management (Redux and related patterns).

• Library & tooling adoption: assess, introduce, and operationalize modern libraries and tooling (migration plans, usage guidelines, guardrails).

• Code quality & mentoring: perform thorough code reviews, pair when useful, and coach teammates on readability, testability, and maintainability.

• Cross-functional collaboration: work closely with backend engineers on API contracts and with UX/design on design system usage and interaction details.

• Defect handling: triage, debug, and resolve bugs efficiently; prevent regressions with targeted tests.

• Communication & stakeholder updates: present demos, explain trade-offs, and provide concise feature updates to internal and external stakeholders/clients.

• Distributed delivery: coordinate hand-offs across time zones; use clear specs, acceptance criteria, and async communication.

• Documentation: record architectural decisions, patterns, and runbooks to reduce single-person dependency.

• Out of scope: security ownership remains with platform/security teams; collaborate as needed but do not lead it.

• Expert React with Redux/state management (, action/reducer patterns, side-effects, store composition) in production systems.

• Strong JavaScript (ESNext) and TypeScript proficiency.

• Solid understanding of frontend architectures (module boundaries, composition, state/data flow, performance, accessibility fundamentals).

• Proven experience with code reviews, collaborating with backend and UX/design partners, and working with distributed teams across time zones.

• Comfortable presenting work (demos, client updates) and communicating clearly with non-engineers.

• Familiarity with Agile methods; SAFe experience preferred (or solid Scrum ceremony participation: PI/quarterly planning, refinement, sprint planning, reviews, retros).

• Advanced level of English

Nice to have

• Exposure to Kubernetes, Docker, and GCP; understanding of CI/CD pipelines and observability basics.

• Experience with automated testing (unit, integration, E2E) and build/bundle tooling.
