Member of the Technical Staff, Product Software Engineer

Description

The company makes cybersecurity software for an era when AI coding agents ship code faster than people can review or secure it. With some engineers opening over 100 pull requests a week, and attackers using the same agents to find and exploit weaknesses within days, quarterly penetration tests and endless alert queues no longer keep up.

The company runs a set of AI security agents. They reason over a live map of your production environment, covering code, CI, cloud and telemetry, and test a faithful copy of it the way a real attacker would. Each finding comes with a validation, its blast radius, and a remediation plan delivered into your existing workflow, ready for a coding agent to apply. Integration takes hours and the first validated finding arrives within days.

The founders have built security products before, including one acquired by Datadog and others used by thousands of organizations. The company is early stage and backed by Accel and Y Combinator.

Responsibilities

• Build the real-time view where teams watch agents work, showing what an autonomous agent is doing, why it is doing it, and how sure it is, without flooding people with logs.
• Design and ship the findings flow: triage, explanation, assignment, and fixing, including blast radius, evidence, and handing the issue to a coding agent.
• Own features end to end across the API, data model, and interface, from a vague problem to a shipped product, and keep supporting them after launch.
• Polish the details people notice: speed, empty states, keyboard use, copy, and small interactions.
• Join customer calls, watch people use the product, and turn friction into fixes within days.
• Help shape the design system, front-end architecture, and the team's approach to product quality.
• Work directly with the founders, the designer, and customers, with real influence over what gets built.
• Make security tools that have a reputation for being dense and noisy feel fast, clear, and trustworthy.

Requirements

• You can spot when something is wrong, explain why, and fix it, and you have shipped products you are proud of that you can show.
• Deep experience with TypeScript and React, and you are comfortable with APIs and databases.
• A record of owning product features from an ambiguous problem through to a polished release.
• You care about UX at every level, including information architecture, interaction design, performance, and accessibility.
• You can handle complex, data-heavy interfaces and make them simple without hiding what matters.
• You use AI coding agents such as Claude Code or Cursor every day and ship quickly without lowering quality.
• Experience building developer tools, security, infrastructure, or observability products.
• Experience designing interfaces for AI or agentic products, where trust and transparency count.
• Design skills of your own, whether in Figma or by prototyping directly in code.
• Experience with real-time interfaces, graph visualization, or large datasets in the browser.
• Prior work at an early-stage startup or as a founding engineer.

Salary is competitive and depends on level and experience.
