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.

You’ll work directly with a highly energetic and driven founder, so we’re looking for someone who matches that enthusiasm and enjoys fast-paced, collaborative environments.

What You’ll Do

  • Design and build scalable backend systems using Python

  • Develop and deploy LLM-based features from 0→1 (prompting, fine-tuning, orchestration, etc.)

  • 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.
