About the Opportunity
G2i is partnering with an innovative, fast-growing AI startup building cutting-edge solutions focused on intelligent document (PDF) processing. This is a high-impact role for a senior engineer who thrives in early-stage environments and has hands-on experience building and deploying LLM-powered systems from the ground up.

• Integrate LLMs into production-grade applications

• Architect and implement APIs and services for AI-driven workflows

• Collaborate closely with the founder and product team to shape the technical direction

• (Optional) Contribute to frontend development using React/Convex

What We’re Looking For

• Strong experience as a Senior/Staff-level Fullstack or Backend Engineer

• Deep expertise in Python

• Proven experience working with LLMs in production (OpenAI, open-source models, or similar)

• Experience building and launching LLM products from scratch (0→1)

• Solid background in startup environments (early-stage, high ownership)

• Strong backend and system design skills

• Ability to independently build integrations and ship quickly

Nice to Have

• Experience with React and/or Convex

• Familiarity with AI-driven document processing or similar domains

Behavioral Fit

• High energy and proactive mindset

• Comfortable working closely with a passionate, fast-moving founder

• Strong communication skills and ownership mentality

Engagement Details

• Contract role (up to USD $65/hour) with strong potential to convert to full-time

• Fully remote, with preference for candidates based in LATAM

If you’re excited about building AI products from the ground up and want to work in a fast-paced startup environment, we’d love to connect.
