VP of Research, Machine Learning
About the Role
A1 is building a proactive AI system that goes beyond responding to prompts – it maintains context across conversations, plans actions, and carries work forward over time.
You will own the research and intelligence direction of this system. Your role is to define how AI reasons, evaluates, and improves in a product used with high frequency.
What You'll Do
- Set and evolve the research direction for A1’s core intelligence, including context representation, memory, reasoning, planning, and orchestration.
- Decide when to design new model architectures versus adapting or leveraging frontier open-source or commercial models.
- Define evaluation frameworks that measure real-world usefulness, robustness, safety, and long-term behavior – not benchmark vanity.
- Own alignment, safety, and guardrail strategy as first-class product concerns.
- Guide exploration of frontier techniques such as:
- retrieval-augmented training
- mixture-of-experts
- distillation
- multi-agent orchestration
- multimodal systems
- Shape early product intelligence direction in close partnership with product and application engineering.
- Set the technical bar for research rigor, judgment, and taste across the organization.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Requirements
- Deep experience building or evolving real machine learning systems used in production.
- Strong technical judgment around model behavior, failure modes, and long-horizon trade-offs.
- A builder’s mindset: you care about systems that work in the real world, not just ideas.
- Comfortable making irreversible or high-impact decisions with incomplete information.
- Obsession with evaluation, correctness, and how systems behave over time.
- High ownership mentality — you operate as a founder, not a manager.
- If you are looking to focus primarily on publishing, incremental benchmarks, or managing a large research organization, this role will not be a fit.
Tech Stack
- Python
- PyTorch / JAX
- GPU-based training and inference system
