Tolmo•San Francisco, CA

About The Position

Tolmo is building cybersecurity products for the age of AI. Its fleet of AI security agents reasons over a live graph of production systems and continuously attacks a faithful copy to identify and validate security findings, including their blast radius and remediation plans. As a Software Engineer on Product, you will build the product surfaces through which customers interact with Tolmo’s agents. You will own Mission Control, where teams monitor agent activity in real time, and the workflows that help users understand, triage, assign, and fix validated vulnerabilities. The role is full-stack, spanning API and data-model design as well as user interfaces. You will work directly with the founders, designer, and customers, and contribute to decisions about what the product should build. Tolmo is based in San Francisco and works in person. The company welcomes applicants from a wide range of backgrounds and is an equal opportunity employer.

Requirements

Strong full-stack engineering skills, with deep experience in TypeScript and React and comfort working on APIs and databases.
A track record of owning product features end to end, from an ambiguous problem to a polished, shipped experience.
Care for user experience, including information architecture, interaction design, performance, and accessibility.
Comfort with complex, data-heavy interfaces and the judgment to simplify them without hiding important information.
Build with AI coding agents daily, such as Claude Code or Cursor, and ship quickly without letting quality slip.
Ability to recognize when a product experience feels off, explain why, and improve it.
Have shipped products to be proud of and be able to show them.

Nice To Haves

Experience building developer tools, security, infrastructure, or observability products.
Experience designing interfaces for AI or agentic products where trust and transparency matter.
Design skills, including comfort with Figma or prototyping directly in code.
Experience with real-time interfaces, graph visualization, or large data sets in the browser.
Prior early-stage startup or founding-engineer experience.

Responsibilities

Build Mission Control, a live view of agent activity that helps users understand what autonomous agents are doing, why they are doing it, and how confident they are.
Design and ship findings workflows for triaging, explaining, assigning, and fixing vulnerabilities, including presenting blast radius and evidence and handing work off to a coding agent.
Own features from an initial idea through API design, data modeling, user interface development, production launch, and follow-up.
Polish product details such as speed, empty states, keyboard flows, copy, and small interactions.
Join customer calls, observe product use, and turn areas of friction into fixes.
Help shape the design system, front-end architecture, and the team’s approach to product quality.
