Staff Security Engineer, AI Product
Hi, we're The Browser Company 👋 and we're building a better way to use the internet.
Browsers are unique in that they are one of the only pieces of software that you share with your parents as well as your kids. Which makes sense, they're our doorway to the most important things — through them we socialize with loved ones, work on our passion projects, and explore our curiosities. But on their own, they don’t actually do a whole lot, they’re kind of just there. They don’t help us organize our messy lives or make it easier to compose our ideas. We believe that the browser could do so much more — it can empower and support the amazing things we do on the internet. That’s why we’re building one: a browser that can help us grow, create, and stay curious.
To accomplish this lofty task, we’re building a diverse team of people from different backgrounds and experiences. This isn’t optional, it’s crucial to our mission, as we need a wide range of perspectives to challenge our assumptions and shape our browser through a bold, creative lens. With that in mind, we especially encourage women, people of color, and others from historically marginalized groups to apply.
As a Security Software Engineer at The Browser Company, you will lead and ship security features built specifically for Dia. This is a hands-on role focused on execution: you’ll drive the highest-impact security work across client and server surfaces, coordinate with multiple teams to sequence priorities, and continually account for AI-driven risks (like prompt injection, tool abuse, data exfiltration) in every design and review. You will report to the Head of Security, working closely with Product, Infra, IT, and Legal to ship security features fast.
Establish metrics and dashboards tracking the effectiveness of our security infrastructure and AI defense to guide priority and measure impact.
Familiarity with AI/LLM security risks (prompt injection, tool-use abuse, data exfiltration) and practical guardrail patterns.
The Browser Company is an ambitious team of close to 100 people (and growing!) who are passionate about building great products. We are a remote-first, distributed team, with the option to work from office in Brooklyn, New York. We strongly support diversity and encourage people from all backgrounds to apply.
