LHH Recruitment Solutions is partnering with a growing organization in the SF Bay Area to identify a Full-Stack Product Engineer for a contract-to-hire opportunity. This role offers the chance to help build a next-generation platform that enables enterprises to optimize how human and digital workforces collaborate.

Position Overview

This is a hands-on, individual contributor role for a product-focused engineer who thrives in fast-paced, early-stage environments. The ideal candidate is comfortable owning features end-to-end—from concept through deployment and collaborating closely with product, design, and executive stakeholders.

You will play a key role in delivering high-impact product features across a modern full-stack architecture, contributing directly to a platform used by enterprise leaders to make strategic workforce decisions.

Key Responsibilities

• Design, build, and deploy product features across a React (Vite/shadcn) frontend and Python (FastAPI/Postgres) backend
• Own the full development lifecycle from early-stage concepts (e.g., Figma mockups and problem statements) through production deployment and executive demos
• Collaborate cross-functionally with product, design, and leadership to define and execute on product direction
• Utilize AI-assisted development tools as part of your daily workflow
• Make pragmatic engineering decisions, balancing speed-to-delivery with scalability and stability
• Contribute to evolving architecture and platform capabilities, including future expansion into LLM-based systems

Qualifications

• Approximately 3–5 years of professional software engineering experience, ideally within a startup or product-driven environment
• Proven experience owning and delivering end-to-end product features
• Strong proficiency in either:
• React / TypeScript, or
• with willingness to work across the full stack
• Demonstrated experience using AI coding tools in a development workflow
• Ability to operate effectively in ambiguous environments with a bias toward execution and delivery
• Must be located within commuting distance of the SF Bay Area and available to work onsite 3 days per week

Preferred Experience

• Familiarity with modern tools and frameworks such as: shadcn, Radix UI, Tailwind CSS, FastAPI, Alembic, Postgres, TanStack Query, Clerk, Supabase, Vercel, Railway
• Target base salary range: $155,000 – $250,000, depending on experience
• Opportunity for conversion to a full-time role and long-term career growth
• Direct impact on product direction with high visibility to leadership

Why Apply

This is a unique opportunity to join a high-growth AI environment where engineering teams have true ownership and the ability to ship meaningful features quickly to enterprise customers. The role offers strong exposure to cutting-edge AI applications and a clear path toward deeper involvement in advanced AI/LLM systems as the platform evolves.
