📋 Description

• Build and maintain features across our React/TypeScript client and NestJS/TypeScript backend, including UI components, REST APIs, and the data layer connecting them. • Design and extend the client-server architecture: state management, routing, authentication (including SSO/SAML), real-time updates via WebSockets, and background job processing via AWS SQS. • Collaborate on the integration layer between the web app and our LLM-based agents — message schemas, queue-based communication, and file/data handoff. • Work with our conversational AI agent system, which orchestrates multiple specialized agents for statistical modeling, data quality checks, and PK/PD analysis workflows. • Contribute to database schema design and migrations (PostgreSQL/Sequelize), API documentation (Swagger), and test coverage (Jest, pytest). • Participate in code review, architecture discussions, and production support across the stack.

🎯 Requirements

• Strong professional experience building production level full stack web applications, comfortable owning features from database to UI. • Strong TypeScript skills across both frontend (React) and backend (Node.js/NestJS) contexts. • Experience designing REST APIs, relational data models (PostGresSQL, MongoDB), and authentication/authorization flows. • Familiarity with message-queue or event-driven architectures (SQS, similar). • Comfort reading and reasoning about systems that integrate with LLMs — understanding agent/tool patterns, prompt-driven workflows, and the practical quirks of working with LLM output, even without deep AI/ML research background. • Strong problem-solving, ownership, and ability to debug across web applications and nondeterministic AI behavior. • Uses Claude Code, Codex, or similar AI coding tools effectively while understanding, validating, and taking responsibility for the resulting code. • Good instincts for reliability and correctness in domains where data quality matters — you ask "what happens when this fails or the data is malformed." • Clear communicator, comfortable working across an evolving codebase with detailed technical documentation. • Operate with a high level of independence and cope with ambiguity. • Nice to Have: • Experience with LLM agent architecture a plus. • Experience with SAML SSO, multi-tenant systems, or healthcare/life-sciences software.
