Job Title: Founding AI Engineer at https:/www.usema.ai

Company Description: https:/www.usema.ai - Embodied AI startup building a new class of living intelligence systems.

Job Description:
You will architect and own the core Living Intelligence substrate for mā, a system unifying multimodal data into real-time semantic states. This is a founding role for a senior systems-level builder to design the narrative engines and orchestration layers that drive proactive guidance across hardware and software interfaces.

Location: San Francisco, USA

Why this role is remarkable:

• Rare opportunity to build the foundational AI substrate for a new category of embodied intelligence, working directly with the founder with zero legacy constraints.

• Unique product scope spanning hardware (ōrb), a generative marketplace, and a persistent living record of user biological and behavioral data.

• Deep ownership of the entire stack, from real-time inference pipelines and RAG architecture to the dynamic narrative engine and agent-style workflows.

What you will do:

• Design and implement the semantic data substrate, unifying wearables, conversations, and environmental context into a persistent graph/RAG architecture.

• Build the narrative engine and orchestration layer to manage low-latency conversational loops and proactive agent-style planning and scheduling.

• Establish the infrastructure foundation, including model runtimes, evaluation tooling, and scalable microservices on AWS/GCP to support real-time sensor fusion.

The ideal candidate:

• Has 6–12+ years of experience in applied ML or AI systems, with a proven track record of shipping production-grade products used by millions.

• Mastery of Python, PyTorch/JAX, and advanced LLM integration, specifically building complex agentic pipelines and multimodal data systems.

• Possesses a systems-thinker mindset with the agency to architect novel, ambiguous systems from scratch rather than tuning incremental features.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
