Senior AI Full Stack Engineer
Careers Leftfieldlabs, Remote
What you need
- Senior-level production experience with React, TypeScript, Next.js, and Tailwind CSS. Experience with design systems (Storybook, Atomic Design), WCAG accessibility standards, and animation libraries (Framer Motion)
- Strong experience with Python (FastAPI), Node.js, and RESTful/GraphQL API design
- Practical expertise in relational databases (PostgreSQL, SQLAlchemy), including migrations, schema design, and query optimization
- Experience with cloud platforms (AWS or GCP), automated testing frameworks, and CI/CD automation via GitHub Actions
- Mastery of modern AI coding assistants and agents (e.g., Claude Code, Cursor, GitHub Copilot) in daily engineering work, using them to generate boilerplate, draft specs, test edge cases, and multiply your delivery speed, backed by a clear methodology for reviewing and validating their output
- Track record of shipping complete, production-ready application features quickly without sacrificing quality
End-to-End Feature & Backend Ownership
- Participate in the entire product lifecycle, building complete, tested features across frontend (React, TypeScript, Next.js) and backend (Python, FastAPI, Node.js) services and PostgreSQL data models.
- Architect and evolve backend features and APIs, ensuring a cohesive flow from backend to frontend while anticipating future scaling challenges.
- Break down complex, ambiguous product requests into clear execution steps, refine technical specifications, and provide realistic estimates.
Platform Engineering & Architecture
- Own platform stability, maintenance, and observability across cloud infrastructure (AWS/GCP) and CI/CD pipelines (GitHub Actions).
- Ensure production code meets high standards for security, performance optimization (Lighthouse 90+), WCAG accessibility, and scalable data modeling using SQLAlchemy/PostgreSQL.
- Account for edge cases, error handling, complex animations/transitions (Motion/Framer Motion), and integration behavior before release.
- Make pragmatic technical decisions that prioritize stability, security, and ROI over novel or overly complex tech choices, and ruthlessly reduce technical clutter to keep systems simple.
Rapid Delivery & Domain Translation
- Rapidly digest complex B2B insurance compliance requirements (policy and coverage rules, certificates of insurance, contract requirements, risk assessment) and translate them into clean, scalable full-stack architecture.
- Abstract dense regulatory and policy logic into simple, consumer-grade experiences that non-insurance users can understand at a glance.
