Backend Engineer (Founding Tech Team)

Think Different. Build the Future. 🚀

Our Mission

Build everyday AGI—trustworthy, consumer-grade agents that redefine human–AI collaboration for millions. Software shouldn’t wait for commands; it should partner with you, amplifying what you can do every single day.

Why AGI, Inc.

We’re a stealth team of elite ex-founders, Stanford and Berkeley researchers, and DeepMind alumni. With years of agent research, our platform already runs live agent workflows with 99.9% reliability. Our investors funded the first wave of AI giants; now they’re backing us to deliver the next—everyday AGI.

About the Role

You’ll be one of the very first engineers shaping our core product and reimagining how people integrate AI companions into their day-to-day workflows.
Expect to:

• Think from zero. Whiteboard the concept in the morning and demo it by evening.

• Own the stack. Backend, frontend, model orchestration, observability—whatever removes friction between idea and shipped product.

• Bridge research and delight. Sit beside scientists, translate breakthroughs into polished consumer experiences, and push them to production in days, not quarters.

• Define the bar. Establish the engineering, design, and reliability standards that every future hire will follfow.

• Move markets. Your features won’t live in a sandbox—they’ll redefine how everyday people trust and collaborate with AI.

You’ll be leading initiatives from conceptual design to production deployment, iterating quickly and putting real user feedback at the heart of product decisions.

Key Responsibilities

• Craft end-to-end experiences: Design, code, and ship full-stack features—Python, TypeScript, Postgres, GPU infra—whatever it takes.
  

• Design the MCP schema: Create flexible, extensible JSON-based models that represent property context, room types, policies, branding, and more.
  

• Integrate core booking systems: Build robust connectors to PMS, CRM, messaging platforms, and booking engines

• Build internal and partner-facing APIs: Develop secure, scalable APIs that ingest, structure, and serve hotel context to downstream AI agents.
  

• Engineer for trust: Single-digit-ms paths, sandboxed execution, telemetry everywhere—four nines or it’s broken.
  

• Invent agentic primitives: APIs, eval harnesses, and safety guardrails that let wild research ship to millions.
  

• Listen, iterate, delight: Sit with users, absorb the pain, and turn feedback into joy—fast.
  

What You Bring

Must Haves

• More than 5 yrs years of professional software engineering experience
