Voltaire, Founder
Research Co-Founder at Voltaire
- Location
- San Francisco, United States
- Compensation
- Not Disclosed + Equity
Join Voltaire as a Research Co-Founder to build Volt, a decision model designed to autonomously operate and grow businesses using a policy trained on decisions and measured outcomes rather than simple prompts. This founding seat is specifically for elite researchers from frontier labs who want to solve complex reinforcement learning challenges and long-horizon credit assignment while taking a significant equity stake in a venture that aims to move beyond reactive LLMs into proactive, goal-oriented leadership.
Role overview
As a Research Co-Founder at Voltaire, you will own the training agenda for Volt, a decision model that operates companies. You will define training objectives, design post-training on sparse signals, and build continual-learning loops. This is a founding seat for a world-class researcher to define an entirely new category of autonomous AI.
About Voltaire
Voltaire is building the engine that runs a company. It connects to the systems a business already runs, holds a living model of the company, and continuously decides which outcomes the whole company should own - each with its evidence, a confidence score recorded before the work starts, and an attribution test when the result lands. Agents do the work. Voltaire holds the intent and the record of what worked. People own the company.
The decision layer - what a company should own - does not exist yet. Voltaire is building it, on a foundation of simulation, memory, self-improvement, and credit.
Voltaire is a pre-funding company in San Francisco, founded by Fabrice Le Parc: HEC Paris Grande Ecole, X-HEC Masters, four startups, one exit, $60M raised across ventures, four years at Logitech. He codes daily and owns positioning, design partners, and investors.
What you will do
- Design and implement post-training for Volt using offline reinforcement learning on logged business decisions and their sparse, long-horizon measured outcomes.
- Build the continual-learning infrastructure that allows the model to improve from real-world results without leaking sensitive data between different business tenants.
- Define the core training objectives and credit assignment strategies that allow a model to navigate confounded signals to optimize for measurable business growth.
Who this is a fit for
- Proven frontier lab experience at DeepMind, OpenAI, or Anthropic, or a PhD from a top-tier group like Stanford or MIT with first-author papers at NeurIPS, ICML, or ICLR.
- Deep technical expertise in reinforcement learning, offline RL, or self-improvement of models, with identifiable public contributions and active training code experience within the last year.
- Exceptional first-principles reasoning with the ability to derive new training methods and state precisely what a signal supports and what it does not in a whiteboard environment.
Why this role is remarkable
- True founding ownership: You own the research agenda and policy architecture outright, working directly with a founder who scaled his first company to $15 million in year one.
- High-stakes research: Voltaire is raising $10M+ from Tier 1 VCs to move beyond reactive LLMs toward autonomous, goal-oriented business policies capable of long-horizon reasoning.
- Unrivaled impact: You aren’t calling model APIs; you are deriving the methods to train models that estimate business states and execute actions through Slack and systems of record.
