Research Engineer, Post-Training
Research Engineer, Post-Training
San Francisco, CA · In Person · Full-Time
Applying to this role will also allow us to consider you for other research opportunities at Vizcom. We believe the best roles are shaped around exceptional people, not just job descriptions.
About Vizcom
Vizcom 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 from investors including Radical Ventures, Index Ventures, and Nat Friedman.
Five years of professional designers working this way has created something difficult to reproduce in a traditional research environment: millions of moments where a trained designer, in the middle of real work, decided what should survive into a product that ultimately has to become real.
Those decisions create a uniquely interesting research problem. A designer's preference among several candidates can reflect the generator's style, where they are in the design process, what they are trying to make, and the professional judgment they bring to the decision. Existing approaches don't cleanly separate those signals.
Understanding that judgment - and learning how to model it - is the challenge this role will help solve.
The Role
As a Research Engineer, Post-Training, you'll work on models that help us understand and learn from the judgment that carries a design from pencil to product.
You'll work closely with the engineers building our post-training stack, contributing to experiments, model training, evaluations, and a growing body of research documenting the approaches we've tested, what we've learned, and where we've found meaningful signal.
This role sits directly between research and product. You'll have the opportunity to see the models you work on ship to working designers, while learning from the real-world signals generated by how those designers use Vizcom.
If your primary goal is research that ends with publication, this may not be the right environment. If you're excited by the idea of helping build models that influence what professional designers see in the product, it probably is.
We also believe the strongest results won't come from clever objectives alone. They'll come from excellent engineering: correct training code, rigorous evaluations, reliable pipelines, and experiments we can trust.
What You'll Own
Execute well-scoped post-training research and engineering projects, from experiment design through evaluation and implementation.
Train and evaluate reward and preference models using years of professional design decisions.
Explore and apply methods including supervised fine-tuning, distillation, preference optimization, and reinforcement learning.
Develop rigorous evaluations that help us determine whether an experimental result is real, reproducible, and worth pursuing.
Work closely with more senior research and engineering partners to translate promising research results into production systems.
Partner with Product and Design to understand how models perform in real workflows and identify opportunities to improve them.
Evaluate emerging post-training techniques and prototype approaches that may be useful within our stack.
Contribute to reliable training and experimentation infrastructure that makes it easier to run, compare, and reproduce experiments.
Document experiments, results, and learnings so the team can build on them over time.
This is a charter, not a week-one checklist. We don't expect one person to tackle everything at once. You'll work with the team to prioritize the problems where you can have the most impact.
What Your First 90 Days Could Look Like
Days 1-30: Learn and map
Understand our data, post-training stack, existing research, evaluation methods, and the approaches we've already tested. Get comfortable running experiments within the existing training and evaluation infrastructure.
Days 30-60: Build and validate
Own a scoped research or engineering problem and produce an initial result using historical data that holds up against our evaluation and reproducibility standards.
Days 60-90: Contribute and expand
Build on your initial work, identify promising follow-up experiments, and contribute to the team's roadmap for improving our post-training systems and connecting model behavior more closely to signals from designers using Vizcom.
What We're Looking For
Strong programming and software engineering skills, particularly for machine learning systems.
Hands-on experience training or fine-tuning machine learning models.
Experience with generative models, including diffusion or flow models, through professional work, research, or substantial technical projects.
Familiarity with one or more post-training methods such as supervised fine-tuning, preference optimization, reward modeling, distillation, or reinforcement learning.
Experience designing experiments and evaluating model performance.
Strong fundamentals in machine learning and an ability to turn research ideas into working implementations.
An interest in product-coupled research, where research questions are informed by real users and models make their way into production.
Comfort working through technical problems where the answer isn't known in advance.
A collaborative approach to research and engineering, including documenting results and incorporating feedback from others.
Nice to Have
Experience building or contributing to high-performance training or inference systems.
Experience optimizing ML workloads or working with large-scale training infrastructure.
Experience working with preference data or human-feedback systems.
Experience taking ML experiments from prototype toward production.
An interest in industrial design, physical products, or the people who make them.
Above all, we're looking for someone who is more interested in understanding how professionals decide than optimizing for what the internet likes.
What You'll Get
A unique dataset: Five years of professional design decisions, with new signals generated every day.
Research that reaches users: The professionals whose judgment you're modeling are also the people using Vizcom. Successful research can reach their workflows quickly.
Meaningful ownership: You'll own substantive research and engineering problems while working alongside experienced teammates who can help you expand your scope over time.
Close product feedback loops: Research insights can directly shape what Vizcom builds and what data we capture next.
Direct access to the founders: You'll work closely with Vizcom's founders and technical leadership as we build out the research function.

How We Work
We document what we learned, not just what we worked on.
Negative results are valuable when they help us close off the wrong paths.
Results should be reproducible before they earn additional compute.
We share meaningful research through technical write-ups, demonstrations, and showcases where appropriate.
Our interview process emphasizes real-world problem solving and practical technical work rather than LeetCode-style interviews.
Location
This is an in-person role based in San Francisco, CA.
As part of Vizcom's SOC 2 Type II compliance program, employment is contingent upon successful completion of a background check, as permitted by applicable law.
