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 AI researchers, and DeepMind alumni.

With years of agent research, our platform runs live agent workflows with 99.9% reliability. We are supported by tier-1 investors who funded the first wave of AI giants; now they’re backing us to deliver the next, everyday AGI.

If you see possibility where others see limits, read on.

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 follow.
  • 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 MCP schemas : 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 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.

    • You Bring

    Must Haves

  • More than 5 yrs years of professional software engineering experience
  • Strong backend fundamentals : REST API architecture, distributed systems, cloud deployment
  • Proficiency with JavaScript, React, and other web technologies
  • Proficiency with a backend language (we use Py C. B thon)
  • Some experience with relational databases like Postgres / MySQL
  • Deep experience integrating 3rd-party APIs and building data abstraction layers (bonus : hotel / hospitality tech exposure)
  • Working knowledge of LLM pipelines, embeddings, and context windows (LangChain, OpenAI Assistants API, etc.)
  • Proven ability to thrive in fast-growing, product-driven companies by effectively navigating loosely defined tasks and managing competing priorities or deadlines.

    • Nice to Haves

  • Familiarity with travel tech (e.g. Mews, SynXis, Oracle Opera, Cloudbeds)
  • Experience designing or managing structured knowledge graphs or JSON schemas
  • Experience with LLMs, prompt engineering, or function calling
  • Former founder, or early engineer at a startup who has built a product from scratch is a plus
  • Interest in AI / ML (direct experience not required)

    • Our Culture

    🏢 All in, in person. Work moves faster face-to-face.

    🚀 Ship by default. Novel and polished can coexist, speed is the feature.

    🤝 One band, one sound. Radical candor, zero politics, help each other win.

    Our perks

    🏥 Fully covered medical, dental, and vision insurance for employees.

    ✈️ Relocation and immigration support.
