## Description

About Tessera Labs Tessera Labs is a new category of enterprise software: an AI platform that changes how the world's largest companies run. Every large enterprise carries the same weight — decades of accumulated process, data, and code that no longer match the business it has become. Changing any of it is a program measured in years and hundreds of millions of dollars, staffed by armies of consultants, and it fails more often than anyone admits. Most companies have quietly accepted this as the cost of being large. We don't. Tessera is a transformation engine: a governed, multi-agent platform that understands an enterprise's process, data, and code as one connected system and changes it in weeks rather than years. We're vendor-agnostic by design — SAP, Salesforce, Workday, Oracle, Snowflake, MuleSoft — and tied to none of them. Two things make this hard, and they're the reason the research is interesting. Governance: every action is logged, traceable, and reversible, because our customers are regulated and these are the systems that close their books. And generality: the platform has to work on landscapes it has never seen, at companies whose complexity is genuinely unique to them. We sell a product, not a service. Our people are here to make the product successful, not the other way around — which is also why research here is a durable investment rather than a line item on an engagement. We raised a $60M Series A led by Andreessen Horowitz, with Foundation Capital, Myriad Venture Partners, and Osage University Partners participating. About the role We're looking for a Research Scientist to set and pursue a research agenda for reliable long-horizon agents operating inside real enterprises. Frontier labs optimize for general capability, and the public agent benchmarks are mostly sandboxes. Very little rigorous work exists on what it takes for an agent to reason across a system with nineteen years of undocumented decisions in it, plan a change across forty coupled steps, recover when step twelve reveals the model of the world was wrong, and be right often enough that a CFO signs the go-live. Almost nobody has the landscapes, the traces, or the customers to study it. We do. Two properties make this an unusually good research setting. First, much of the task space is verifiable — a transformation either produces a system that builds, passes regression, and behaves equivalently, or it doesn't. That's a real reward signal, not a preference model. Second, the parts that aren't verifiable are where the interesting work is: is this reconciliation correct, or merely plausible? Was retiring that capability the right call? Designing reward and evaluation across that boundary is the central research question here. You'll invent methods rather than only apply them, work with Research Engineers who help you run at scale, and hear from a product team within weeks whether you were right. We'd like you to publish. Not everything, and never at the expense of shipping — but the work here is novel enough to be worth writing down. One thing worth knowing up front: we post-train open-weight models on rented clusters and buy more compute when a result justifies it. We're constrained relative to a frontier lab. If your research only works at ten thousand GPUs, this is the wrong place. What you'll do Set and pursue a research agenda on reliable long-horizon agentic behavior in real enterprise environments — you decide which questions matter, and defend the choice. Invent and validate methods for post-training agents on transformation work: reward design where verification is partial, delayed, or contested; RL formulations for long-horizon planning and tool use; curriculum and data strategy. Post-training and RL are the core of this role. Define how an agent remembers. Memory architecture for runs that span forty steps and days of wall-clock — what persists, how it's structured and retrieved, how it's revised when the world turns out to be different,
