Senior Software Engineer

Role Description

As a Senior Software Engineer on the browser extension team, you'll be equal parts builder and architect. Beyond shipping high-quality extension features, you will drive the technical design of the extension platform itself:

• Architecting solutions to genuinely hard problems like reliably observing authentication flows across thousands of SaaS apps.
• Intercepting and interpreting OAuth grants in real time.
• Managing credentials safely within the browser's security model.
• Monitoring AI platform usage while staying performant and private to the end user.

You'll set the technical direction for the extension, lead design reviews, and raise the bar for engineering quality across the team. Over time, we expect this person to grow into broader technical leadership of the extension team while remaining hands-on. You'll work remotely as part of a distributed team of engineers in a fast-paced, high-security environment characterized by continuous delivery and rapid feature growth.

Qualifications

• 5+ years of professional software development experience, with demonstrated ownership of technical design and architecture for a significant product or system.
• Proven experience developing and shipping web browser extensions (e.g., Chrome, Firefox, Edge, Safari).
• Strong technical understanding of authentication on the web: OAuth 2.0 grant types and scopes, OIDC, SAML/SSO, session management, cookies, and token handling.
• Strong proficiency in TypeScript and JavaScript, with a solid grounding in web platform fundamentals (HTML, CSS, DOM, networking).
• Hands-on experience using AI tools for software development, and enthusiasm for making AI a multiplier for the team.
• Excellent written and verbal communication skills.
• A security mindset, or a strong desire to develop one.

Requirements

• Experience with extension frameworks such as Plasmo and/or WXT, and with React or other modern JavaScript frameworks.
• Experience building or integrating LLM-powered features into a product.
• Experience shipping software into enterprise environments: managed browsers, group policies, and enterprise extension deployment.
• Familiarity with CI/CD pipelines for extension build, signing, and multi-store deployment.
• Experience leading or mentoring a small team of engineers.
• Background in security, identity, or the broader cybersecurity product space.
• Startup mindset: you thrive with ambiguity, prioritize ruthlessly, and build pragmatic solutions over perfect ones.

Benefits

• Competitive salary and benefits, including health insurance, 401K, options, and PTO.
• Fully remote position, with the opportunity to work with an experienced and passionate team of professionals from around the world.
• Excellent career growth and advancement opportunities within a rapidly growing company in the cybersecurity sector.
• Individual compensation is determined based on experience, skills, location, and other job-related factors.
