Ambral has already been used to drive hundreds of millions of dollars in attributable expansion revenue at multi-billion dollar enterprises and top scale-ups. Ambral synthesizes signals from all customer activity and interactions into AI-powered models of every account. It pinpoints who needs attention and why, and autonomously takes the best next action to drive expansions, prevent churn, and ensure no customer slips through the cracks. Team: Sam (CEO): 2x founder. Led AI at Everlywell and early PM at Wonder (now valued at $7bn). Lived the pain of losing customer intimacy at scale and is obsessed with solving it. Jack (CTO): Ex-SpaceX Flight Software Special Projects, where he developed telemetry routing and analysis systems for the most complex machines ever created. He’s now doing the same for the complexities of customer relationships. ## About the role #### What we do Ambral helps enterprises own the intelligence behind their most important workflows. Every company has years of historical evidence showing how work gets done: the context people had, the decisions they made, the actions they took, and the outcomes that followed. Today, most of that history is inert. It isn’t structured in a way that companies can use to evaluate models and improve agent behavior. Ambral turns this history into replayable environments and eval sets grounded in real workflows and observed outcomes. We use those environments to improve model performance through reinforcement learning and other post-training techniques, alongside context engineering, harness design, and agent engineering. The result is better, more cost-efficient AI for each enterprise’s specific work, powered by open-weight models that the company owns and controls. This allows each company to retain ownership of its core workflow intelligence instead of outsourcing it to a model provider. We graduated from YC S2025, raised millions in funding, and are already deployed within multi-billion dollar enterprises. Now we're growing the founding team. #### What you’ll do We’re building a *replayable environment engine* over real enterprise history. The system reconstructs a company’s context as it existed at any past time, then exposes that state through the same tools an agent would use in production. This lets us place new policies and agent configurations inside real historical environments, observe how they reason and act, and grade their performance against real outcomes. You’ll help build the infrastructure and work hands-on with customers to turn their real enterprise data into a scalable, continuous model-improvement system. The core problems include: - Forward deploying with our customers to understand their tasks and data - Developing the environment factory that converts recorded enterprise data and task definitions into runnable environments - Designing graders to turn ambiguous business objectives into verifiable rewards - Developing methods for mining useful tasks, trajectories, and evaluation cases from historical workflows - Experimenting with learning objectives and task design - Creating eval sets that are representative, reproducible, and resistant to overfitting - Finding the right combinations of models, tools, context, and policies to maximize performance while reducing inference cost - Building replay and observability systems that make agent behavior explainable and measurableThese problems are wide open. You’ll have significant ownership over the production systems that make it real. You’ll work directly with the CTO, deploy into real enterprise workflows, and see your implementations tested against consequential problems and observable outcomes. #### Who you are - You have experience building production-grade software (internships are ok) or in a quant role - You write strong software and can build systems that process large, messy datasets at scale - You have great intuition about systems, abstraction, and data structures - You’re comfortable turning fuzzy business objectives into tasks and signals that can be evaluated reliably - You can diagnose whether a model’s limitations come from the model itself, its context, its tools, its harness, or its training - You can move between research questions and production implementation without treating them as separate jobs - You care about reproducibility, observability, and understanding why a model behaves the way it does - You’re looking to do the best work of your life and build something you’ll be proud of for decadesWe care much more about what you’ve built and how you think than credentials or conventional career paths. #### #### Benefits - Significant equity and ownership - Equinox membership - Free meals, coffee, and snacks - Health insurance - Unlimited PTO --- Source: Ambral's own career page, read by RemJobs.
