Founding AI Engineer at Mā
Join https:/www.usema.ai as a Founding AI Engineer to architect the 'Living Intelligence' substrate of a generational embodied AI platform. This isn't a research role; we're looking for an elite systems-level builder to unify multimodal data—biological, behavioral, and contextual—into a real-time narrative engine. You’ll own the entire AI stack from the ground up, collaborating directly with the founder to define how AI interacts with the physical world through hardware and a new operating substrate. If you've shipped ML systems at scale at places like Apple, DeepMind, or OpenAI, this is your chance to build a legacy-free system with total ownership.
About this role
Role overview
About the company
Mā
Mā AI (usema.ai) is an intelligent operating system for life that serves as an ambient layer aimed at unifying body, mind, and meaning into a single living signal. The company combines advanced artificial intelligence with both software and hardware to sense, process, and guide individuals, helping them maintain coherence in a fragmented world. Their technology provides personalized guidance on nutrition, exercise, meditation, and overall wellness through integrated sensing and adaptive recommendations, creating a holistic wellness experience.
What you'll do
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.
Who you are
Who this is a fit for
- 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.
Why this role
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.
