About Emulated
Emulated builds high-quality, long-horizon RL environments and post-training data for frontier labs — customers include all five US frontier labs (OpenAI, Anthropic, DeepMind, etc.) plus top international players, with active engagements across them. What makes it different: unlike most data vendors that treat post-training data as a human-services problem (throw bodies at capability gaps), Emulated treats it as a technical and research question — the forward-looking vision is to scale superlinearly with talent by building a model capable of producing post-training data autonomously (a very "bitter-lesson-pilled" company). It's cash-flow positive, raised a sub-$1M pre-seed, and ~3 months later an angel who'd tracked their progress made an impromptu seed offer they accepted (to fund the expensive model-training direction). The team (~9–12) is elite: a published neuroscience research lead who optimized Anthropic's circuit-tracer library (mech-interp) and built the world's fastest DBSCAN; founders Sid and Joseph with AWS software backgrounds (distributed databases; network infrastructure) — one a former musician, the other a chemistry olympiad; plus ex-Google/DeepMind/NVIDIA and a Stanford shock-physics PhD who works with national labs and the Stanford supercomputer. They just released a benchmark, Auto Research (evaluating models' ability to iterate in an ML-research loop), which drove strong frontier-lab interest.

About This Role

Inbound demand for post-training data quality exceeds what Emulated can currently fulfill, so this hire is about scaling the talent to meet demand. The shape they've found works best — and the one to source for — is a domain/research expert with a strong ML-or-engineering spike: someone who both does research and produces data, because in Emulated's thesis the two are inseparable (their research lead builds post-training data extensively). For this early hire they're explicitly merging the research and data-production archetypes into one person.

The technical scope is broad: post-training models as effectively as possible (from provisioning infra through curating high-quality post-training data from their generation processes), and — critically — scaling data generation superlinearly with human intervention. A core competency is data taste: good judgment about what problems pervade a domain and what makes a realistic, economically valuable task/environment a lab will actually buy. They index on research/ML horsepower first. Above all they screen for high slope.

What You'll Own

  • Post-training models end to end — infra provisioning through curating high-quality post-training data
  • Producing RL environments / long-horizon tasks across domains (incl. research-loop, science, chip, and shock-physics-type environments)
  • Scaling data generation superlinearly via self-improving developer processes, not more bodies
  • Exercising and developing data taste — realistic, economically valuable tasks/environments labs will buy
  • Blending research and data production as one function (the company's core thesis)

Requirements

  • A genuine spike in ML/AI research (post-training, RL, evals, interpretability, or similar) plus strong software-engineering ability — the dual competency is the whole shape
  • Can post-train models and build/curate high-quality post-training data (the two are inseparable here)
  • Data taste, or the research horsepower to develop it fast
  • Fast problem-solving / code comprehension (their technical round tests how quickly you understand code and problem-solve, not rote LeetCode; ML variant uses PyTorch / debugging ML pipelines)

Background

  • Domain/research expertise in a specific field + ML/eng core (neuroscience, physics, chemistry, systems, etc. all fit — breadth is the culture)
  • Pedigree is a soft signal, not an index: Palantir / Anthropic / OpenAI welcome; competitor data cos (Surge, Mercor, Fleet) interesting but less defined

Who Will Thrive Here

  • A researcher-engineer who treats data as a research problem and wants to build the model that makes data
  • High-slope polymath with a real spike who figures anything out
  • Someone with (or fast to develop) taste for lab-valuable tasks/environments
  • Deeply committed, results-driven, obsessive builder with public artifacts
  • Excited by the bitter-lesson, superlinear-scaling thesis and frontier-lab customers

Green Flags
Publications + shipped side projects / notable open-source (the archetype)
Post-training / RL / interpretability / evals research
Domain expertise (neuro, physics, chem, systems) + ML core
Red Flags
Data-services mindset (scale via headcount, not self-improving processes)
Strong engineer with no research spike (or vice versa) — they want both
No data taste and not a fast enough researcher to gain it
