Full Stack Engineer (Frontend Focused)

Data Science problems are everywhere, but the talent is not. At Zams, our vision is to turn every company into an AI company. Zams is the Sales Automation platform for B2B companies. Top reps use Zams to automate tasks across HubSpot, Slack, Clay, Apollo, Gong and 100+ tools, saving 20+ hours per week and closing 3.2x more revenue.

We’re a small, scrappy group of people with a strong bent toward failing fast, bias for action and attention to detail. We’re focused on doing the best work of our lives and believe in having a healthy separation of work and life. We keep working hours flexible and are building a hybrid team with most of us located in San Francisco, CA and others working remotely around the world.

Zams is backed by some of the top venture capital firms in the US, and you’ll be on the ground floor of a fast-growing company with a big mission.

About You

As a Software Engineer at Zams, you'll be on the ground floor of an incredible opportunity to pair your engineering mastery with solving critical business challenges across industries. Zams is already powering automation for companies, and our users deeply value our speed, reliability, and customer-centric approach.

In this role, you’ll be a core contributor to the product itself—not just building features, but shaping the way the entire platform evolves. You’ll work across all layers of the stack, from crafting intuitive frontends to architecting robust backend systems. This is a rare opportunity to touch every component of a high-impact product, while working side by side with the founding team.

We're looking for someone who thrives in a scrappy, fast-paced environment, has strong knowledge of AI and LLMs, and is eager to learn continuously. You should be excited by the idea of solving a wide range of engineering and data challenges with autonomy and ownership. If you’re passionate about building, shipping fast, and learning new things every day, we’d love to meet you.
