AI-Driven Full-Stack Engineer - React/GraphQL

YPO; United States; Remote; USD 120,000 - 160,000; Full time

Job summary

YPO seeks a Senior Full Stack Engineer to own features from the member-facing React UI through the GraphQL API layer and into AI-powered data services. You’ll work across the stack—from React and TypeScript to NestJS, PostgreSQL, Redis, and Kafka—leveraging OpenAI and Google Gemini.

Design, instrument, and iterate on production features with a strong emphasis on reliability and security. You will partner with product, design, security, and DevOps to deliver scalable, secure, and measurable

Qualifications

• 5–7 years of professional software engineering experience shipping production-grade products end-to-end.
• Strong TypeScript/React skills (component architecture, state management, hooks, performance).
• Backend experience with Node.js and NestJS building modular, tested services.
• GraphQL experience (schema design, resolvers, subscriptions, Apollo client/server) and familiarity with API gateway patterns (Apigee or equivalent).
• PostgreSQL proficiency (query optimization, schema design, TypeORM/Prisma).
• Experience with Auth0 or equivalent identity platforms.
• Familiarity with Redis and Kafka (or similar) for caching and event-driven/message-queue patterns.

Responsibilities

• Own the full feature lifecycle architecture, implementation, code review, QA, deployment, and post-launch monitoring.
• Build responsive React/TypeScript frontends integrated with Optimizely; design Apollo GraphQL schemas and resolvers served through Apigee; build modular Node.js/NestJS backend services using Redis for caching and Kafka for event-driven workflows.
• Design and query PostgreSQL schemas (TypeORM/Prisma); collaborate on Snowflake pipelines and dbt models feeding the Leadership Intelligence layer.
• Integrate OpenAI and Google Gemini APIs for AI-powered discovery, recommendations, and matching; work with Neo4j graph data for relationship-driven insights.
• Use AI-assisted development workflows (pair programming, code generation, test scaffolding) to increase velocity without compromising quality; handle AI feature failures, timeouts, and token costs with a production mindset.
• Instrument features with PostHog and Datadog; design and run A/B experiments and feature-flag rollouts via Optimizely; use data to drive iteration.
• Contribute to architecture decisions, ADRs, and post-incident reviews; address performance bottlenecks across the stack (GraphQL resolvers, N+1 queries, frontend rendering, mobile time-to-interactive).
• Partner with product, design, the Lead Security Engineer, and DevOps to ensure features are secure, well-architected, and operationally sound from the start.
