Who We Are Seeking

Left Field Labs is partnering with illumend to find an AI-native Senior Full Stack Engineer who ships production-grade code at high velocity, combining strong implementation skills with high ownership, architectural judgment, and reliable execution. This is a hands-on individual contributor role in a lean, fast-paced environment. Working closely with our Director of Engineering, you will own features across the entire product lifecycle—from initial concept and technical spec to production deployment, monitoring, and ongoing optimization.

AI is central to how we work. You are expected to fully embed AI development tools and agents (e.g., Claude Code, Cursor, Git Hub Copilot, ChatGPT) into coding, refactoring, testing, review, troubleshooting, and documentation, using them to multiply your individual output while taking full responsibility for validating everything you ship. You will also actively share the workflows that make the whole engineering team faster.

What You Will Do

• Participate in the entire product lifecycle, building complete, tested features across frontend (React, Type Script, 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 (Git Hub Actions).
• Ensure production code meets high standards for security, performance optimization (Lighthouse 90+), WCAG accessibility, and scalable data modeling using SQL Alchemy/PostgreSQL.
• Account for edge cases, error handling, complex animations/transitions (Motion/Framer Motion), and integration…
