Epsilab (YC F26) is an applied AI research lab building training simulations for real-world AI agents. We create high-fidelity reinforcement learning environments that recreate enterprise software, tools, and complex professional workflows, helping agents learn to complete long-horizon tasks.
We’re a fast-growing startup working with frontier AI labs. Our team is extremely flat, fast-moving, and creative: you’ll work directly with the founders, contribute ideas across the company, and take ownership from first experiment to shipped product. We value technical curiosity, clear thinking, and people who turn ambitious ideas into working systems.
As our Technical Strategic Projects Lead, you’ll own high-priority projects across engineering, research, and delivery. You’ll translate open-ended needs from frontier labs into technical plans, build prototypes and internal tools, and bring engineers and domain experts together to ship reliable RL environments and evaluation datasets.
You will have direct ownership of deciding what we build next and executing to get it working. Projects will require intense effort, attention to detail, and technical understanding. We are looking for people who will do whatever it takes to solve immediate bottlenecks, while also thinking in systems and building compounding loops.
You will be at the frontier of AI development every day solving agentic knowledge work and the broad diffusion of AI.
RL environments, agent evaluations, developer tools, data pipelines, or shipping projects directly with customers. Finance, consulting, and investing experience are not required.
