Machine Learning Data Engineer

ML Data EngineerSan Francisco, CA · In Person · Full-TimeVizcom is where design teams at companies like Nike, GM, New Balance, and Hasbro bring ideas from sketch to product. Designers use Vizcom to sketch, render, explore color and materials, work in 3D, and prepare concepts for production. The render itself was never the point. The point is the physical thing that comes after it. We call this pencil to product.Vizcom is a Series B company with more than $52M raised. More than 700,000 designers have worked in Vizcom, and every session leaves a trail: candidates selected, outputs promoted into designs, regions masked and renamed, and entire directions kept or discarded. That trail is one of the most valuable things we create outside of the product itself. Today, though, it's more archaeology than asset. Only a fraction of what happens in a session reaches training-grade quality, while increasingly sophisticated post-training methods depend on exactly this kind of high-quality, domain-specific data. Your job will be to turn that trail into a machine.A design session isn't a simple sequence — it's a branching tree. Designers fork, backtrack, iterate, and abandon entire directions on their way to the thing they ultimately keep. The judgment lives in the shape of that process, and today we capture only pieces of it.The RoleAs an ML Data Engineer, you'll build the data flywheel itself: the systems that turn professional design work into training-grade preference data and training results back into a better product. You'll work alongside the researchers consuming what you build, within the product systems where these signals originate, and across the data infrastructure where they ultimately land. Your closest users are the researchers sitting beside you, and you'll see quickly when a dataset you've built allows them to ask a question they couldn't ask before. This is not a support role, and it isn't traditional offline ETL. The pipelines you design will run through a live product used every day by professional design teams, including enterprise customers with rigorous expectations around privacy and data protection. Capturing better signals without compromising user trust, contractual obligations, or product performance is a core part of the work. If you want to train models without building the systems that feed them, this probably isn't the role for you. If you believe the next advances in ML will increasingly be won through better data, it might be.We think about a dataset as a product: it has users, versions, provenance, and a quality bar. A training result should be reproducible from a dataset fingerprint months later, and "Where did this example come from?" should always have an answer. Here, building that standard is the job.What You'll OwnThe capture surface: Determine what the product records, working closely with Product and Engineering to design and ship instrumentation in production systems.The data pipeline: Build the path from canvas to warehouse to training set, ensuring data is clean, versioned, reliable, and reproducible.Dataset contracts and lineage: Make every example traceable to its origin and every training dataset reproducible months later.Privacy and data boundaries: Build systems that reflect what can be captured and used under different enterprise agreements, with consent, isolation, and appropriate safeguards designed in from the beginning.Research-ready datasets: Create appropriately governed and sanitized datasets that allow researchers to experiment safely and effectively.Collection instruments: When historical signals aren't enough, build mechanisms for gathering explicit feedback that designers actually want to use.Honest representations of ambiguity: Design data systems that preserve context. Unpicked doesn't necessarily mean disliked, abandoned doesn't necessarily mean rejected, and our data should reflect the difference.This is a charter, not a week-one checklist. We don't expect one person to tackle everything at once. Part of the role is helping determine what matters most and in what sequence.What Your First 90 Days Could Look LikeDays 1–30: MapUnderstand the event surface, warehouse, existing datasets, research workflows, and current data boundaries. Identify what exists, what's missing, and which research questions our data can't yet answer.Days 30–60: ShipTake one new signal end to end: instrumented in the product, landed reliably in the warehouse, versioned appropriately, and available to researchers.Days 60–90: Establish the standardDefine the data standards that future work will build on, including versioning, dataset fingerprints, lineage, quality, and data boundaries.What We're Looking ForExperience building training-data infrastructure, ML data systems, or large-scale data pipelines that other teams depended on.Strong software engineering skills and experience building reliable production systems.Experience designing data models and pipelines with reproducibility, observability, and lineage in mind.An experimental mindset and comfort working closely with researchers to turn ambiguous questions into measurable datasets.Strong judgment around data quality, including an understanding of when the absence of a signal is meaningfully different from a negative signal.Comfort operating in an environment where the underlying systems and standards are still being built.Nice to HaveYou've trained models yourself and understand what ML training pipelines actually need from their data.You've worked with preference data, labeling systems, human-feedback pipelines, or evaluation operations.You've built data infrastructure under meaningful privacy, security, or contractual constraints.You've worked with large-scale event or behavioral datasets.You have experience with data systems supporting generative AI or multimodal models.Above all, we're looking for someone who can look at the exhaust of a complex product and see evidence.What You'll GetA unique dataset: The recorded decisions and workflows of more than 700,000 designers, with new signals generated every day.Researchers as your users: You'll work directly alongside the people using the datasets you build, creating an unusually tight feedback loop between data engineering and research.High ownership: You'll help establish the standards for how Vizcom captures, versions, governs, and uses ML training data.A rare problem space: High-quality professional preference data is difficult to create. You'll have the opportunity to build systems around a dataset and domain that few ML teams have access to.Direct access to the founders: You'll work closely with Vizcom's founders and technical leadership as we build out our research and ML infrastructure.Benefits at Vizcom100% employer-sponsored medical coverage for employees, plus 25% coverage toward dependentsDental and vision coverage, plus mental health benefitsMeaningful equity ownershipFlexible PTO401(k) with employer matchGenerous annual Learning & Development allowancePaid parental leaveWeekly catered lunch at our San Francisco headquartersMonthly gym membership stipendCompensationBase salary: $220,000–$300,000 USD + equityWe regularly benchmark compensation against relevant peer companies using current market data from industry-standard sources, including Carta and Pave.
