About 11x

Most of what GTM teams do all day isn't selling. It's monotonous work like research, list-building, follow-ups, and data entry - things that should never have been a human job in the first place.

11x is building the AI platform for growth by automating the busywork so GTM teams can focus on what they do best: building relationships and closing deals.

Backed by $75M+ from a16z and Benchmark, headquartered in San Francisco, and trusted by leading teams at Checkr, Xerox, Rillet, and much more. We're hiring ambitious people who want to define how the next generation of companies accelerate growth.

About the Role

We’re looking for a product-minded fullstack engineer to build the core experiences that power our AI agents. You’ll work across the stack, from user-facing product experiences to the systems that orchestrate and deploy autonomous agents, partnering closely with Product, Design, and AI/Engineering.

This is an in-person role based in our San Francisco office, where our team works together five days a week.

What You'll Do

Design, build, and iterate on fullstack systems that power AI agents from concept to deployment.
Research and evaluate new approaches to agent orchestration, prompting strategies, and model alignment.
Collaborate with product, design, and engineering teams to improve UX and usability for non-technical users.
Share learnings, document findings, and contribute to the evolution of internal best practices.
Participate in peer reviews, brainstorming sessions, and technical deep dives with our global team.

Ideal Candidates Have

3+ years of experience in a product-oriented software engineering role.
A strong foundation in Typescript, React, NextJS, and NodeJS.
Experience working in fast-paced environments with a track record of rapid learning and iteration.
Interest in research, technical writing, or contributing to knowledge-sharing within a team.
Bonus: experience with large language models, prompt engineering, or AI infrastructure.

Base salary range: $180,000 – $250,000

*Final offer will be based on a variety of factors, including role level, relevant experience, skills, and job-related expertise.

What We Do

At 11x, we’re not just building tools—we’re redefining how work gets done. We build autonomous digital workers that execute entire go-to-market workflows, end-to-end. Instead of just augmenting tasks with AI, 11x automates the full execution of sales, marketing, and RevOps processes so teams can focus on what they do best: building relationships, closing deals, and driving impact. Our technology integrates across GTM systems, adapts to real business logic, and learns continuously while delivering real outcomes. These aren’t just incremental improvements, they’re game-changing leaps forward in how companies grow.

Why Work With Us

Everyone here is a builder. You’ll be starting at the ground floor of a rocket ship company with the rare opportunity to leave your mark, shape the culture, and have a seat at the table as we scale. You’ll work side-by-side with a world-class team—people who move fast, think deeply, and care fiercely. The upside? Massive.
