Fullstack Product Engineer

In 2025, tools like Cursor, Devin, and Claude gave engineers superpowers, allowing them to ship faster than ever before. But for the rest of the world — Sales, Ops, Marketing, and Finance — work largely hasn't changed. They're still drowning in Slack threads, manual data entry, and "good enough" ChatGPT responses.

We're here to fix that.

Vellum is building the platform where anyone can describe a goal in plain language and generate reliable, working agents in seconds (think "Lovable for agents" and "Devin for everyone else").

We're a high-performance team in one of the most competitive software markets of all time, so we're looking for S-tier builders who align with our core values:

We don't just build AI tools; we live in the future.

• We use AI tools (Cursor, Claude, etc.) extensively in our daily workflows.

• We skate to where the puck is going. You should be excited to build what customers need before they even ask for it.

• We cut the right corners to go fast, but we build our products and processes for the long run.

We operate in an extremely high-trust environment.

• We speak openly and honestly, even when it's hard.

• We receive feedback without getting defensive.

• If we say we're going to do something, we do it. If we can't keep a commitment, we communicate it immediately.

There are going to be huge companies built in this space, and we're going to be one of them. We've raised $25M from top-tier investors and we intend to spend it aggressively to win this market. In other words, we're swinging for the fences.

• We love winning and know it won't be easy. This means we move extremely fast, make sacrifices, and do whatever it takes.

• We demand executional excellence from ourselves and each other.

• We push ourselves hard to maximize long-term output and are resilient to burnout.

• You've founded or worked at an early-stage startup.

• You're a master of Typescript, React, and Python.

• You're deeply product-minded - you care about the "why" and the "who," not just the "how."

• You're an early adopter of AI tools that make you more effective.

• You're ready to build alongside us in our New York office.

• You crave ownership and are ready to take on significant responsibility from Day 1.

• You're excited to build the tools that will redefine how people work.

If this sounds like you, welcome home.

Let's get to work.
