Senior Full Stack Engineer
eSimplicity
• Lead discovery and consulting sessions with clients and internal teams to clarify goals, constraints, and success metrics; separate true needs from wants. • Propose Agentic AI-enabled solutions: identify high-ROI opportunities; outline architectures for agent orchestration, tool integrations, APIs, data access patterns, and guardrails; communicate tradeoffs and risks. • Architect and implement full-stack solutions spanning frontend experiences, backend services, APIs, data persistence, and cloud deployment. • Design and deliver modern user experiences in React/TypeScript with Tailwind or CSS-in-JS. • Build accessible, reusable components and maintain design system consistency. • Design, build, and secure APIs (REST/GraphQL; OpenAPI), integrations, and data flows using Node.js (preferred) or Python; leverage Postgres, Redis, and event-driven patterns where appropriate. • Implement JSON Schema-driven forms and admin flows (e.g., React JSON Schema Form) and connect them to scalable backend services. • Drive consistency and quality across front-end and back-end implementations in multi-app or distributed environments. • Own backend architecture decisions including data modeling, caching, background processing, and service boundaries. • Communicate clearly: author decision records, design docs, runbooks, and client-facing summaries; present options and recommendations to mixed audiences. • Participate in Agile processes including daily standups, demos, retrospectives, and sprint planning; collaborate closely across engineering, DevOps, UX, Product, and Scrum Master roles. • Instrument applications for observability (logs, metrics, traces), performance, and accessibility (WCAG/Section 508); support reliable releases with Git and CI/CD. • Deploy and operate services in AWS environments using containerization and infrastructure-as-code patterns. • Provide support, maintenance, and enhancements to existing systems; quickly adopt new programming tools, frameworks, and techniques as project needs evolve.
