About the role
What we're looking for:
We need a highly technical engineer with deep experience in distributed systems, LLMs, and simulation infrastructure who can operate with extreme ownership and a founder mentality. You should be comfortable working across the full stack—from customer-facing products to internal infrastructure—and have a track record of building systems that scale to billions of events. Bonus points if you have experience with reinforcement learning, AI agents, or prior founding experience.
What you'll do:
- Own and extend key parts of the core simulation engine, adding new features and improving performance metrics such as throughput and cost
- Build and scale infrastructure capable of handling 10B+ events and tens of thousands of monthly users (both human and virtual)
- Work directly with the Head of Engineering to architect, build, and deploy projects across customer-facing products and internal systems
- Leverage coding agents (Codex, Claude Code) to accelerate development velocity and establish best practices
- Establish engineering culture and standards as the technical team continues to scale
- Stay current with SOTA research in evaluations, RL, and agent architectures, translating papers into production systems
About Abundant
AI models rely on two fundamental ingredients: compute and data. Abundant is building the NVIDIA of training data. NVIDIA, the leader in compute, has a peak market cap of $5T and generated $130B in revenue last year as the need for scaling compute has exploded. We believe the need to scale data is just beginning, as we move beyond SFT and human supervision to RL and Learning from Experience.
Our founding team consists of former founders, ML engineers, roboticists and data leads from Waymo, Google, Mercor and AWS. Our team has previously worked with DeepMind to deploy deep learning models at 1B user scale, trained SOTA models for self-driving at Waymo, and scaled data pipelines of tens of thousands of human annotators at YouTube. Our pioneering work in human computation, synthetic data, simulation and RL give us the advantage in delivering results to our customers.
Why now? Training data is more important and more scarce than ever before. Scaling laws dictate that linear improvement in model performance demands an exponential increase in training data. But there is only one World Wide Web and most of it has already been trained on. The next advances will require major advances in simulation, synthetic data and learning from experience.
What happens if we succeed? Abundant will be the core enabler for not only AGI, but ASI and physical intelligence. Most of the challenges in model algorithms and compute are already solved. What’s missing? The data necessary to move from general knowledge to domain expertise; from chatbots to agents; and from text to multimodal and physical AI. Ask any AI researcher or roboticist: the core bottleneck to progress is the availability of data, hence “abundant data”.
