Job Description

• 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.

Job Requirements

  • Minimum of 7 years related experience delivering production-grade full-stack web applications on small, cross-functional teams.
  • Exceptional communication and writing skills; adept at facilitation, stakeholder alignment, and translating complex topics for mixed audiences.
  • Demonstrated consultative problem-solving: discovery, option framing, impact/risk analysis, and solution proposals.
  • Hands-on experience enabling Agentic AI solutions (e.g., multi-step/agent orchestration, tool-use integration, prompt/eval harnesses, safety/guardrails).
  • Expert-level proficiency in at least one of the following languages: TypeScript, JavaScript, Python; strong proficiency across both frontend and backend patterns.
  • Strong proficiency with React and modern frontend ecosystems.
  • Deep experience building and securing backend services, APIs, and distributed systems.
  • Proficiency in Node.js (preferred) or Python for server-side development.
  • Experience with relational databases (Postgres) and in-memory stores (Redis); familiarity with data modeling and performance optimization.
  • Deep understanding of APIs; familiarity with JSON, Web APIs, REST APIs, JSON-RPC, RESTful practices, and GraphQL; experience defining APIs with OpenAPI.
  • Experience building dynamic forms and admin panels using JSON Schema and React-based builders.
  • Familiarity with web accessibility (WCAG and Section 508) and performance optimization best practices.
  • Experience with modern frameworks such as React.js, Next.js, Node.js, and backend service frameworks.
  • Testing with Jest and Testing Library plus Playwright or Cypress; BDD with Cucumber is a plus.
  • Experience with Docker containerization and deployments.
  • Hands-on experience with AWS cloud services (compute, networking, storage, IAM).
  • Extensive experience using Git and CI/CD platforms to deliver safe releases at a rapid rate.
  • Experience working on a fully integrated Agile product team smaller than 10 people.
  • A demonstrated preference for the right amount of unit and integration tests across frontend and backend systems.
  • Strong documentation and problem-solving skills.
  • Flexible and willing to accept a change in priorities as necessary.
  • Ability to work in a fast-paced, team-oriented environment.
  • Excellent command of written and spoken English.
  • Ability to obtain and maintain a Public Trust; must reside in the United States.
  • Communicates technical information to non-technical audiences.
