Product Security Engineer (Founding team)

Aglide's browser agent platform is trusted by household-name fintechs and global enterprises to automate and secure the applications their employees depend on most. We've raised over $3.5M to go after this problem, and every day our platform is running thousands of mission-critical workflows.

Our founding engineers take on high-ownership roles, working directly with customers to invent new ways to securely and reliably automate web tasks - shaping product direction and building the core infrastructure for a category that's still being invented.

What we do

Aglide combines an on-device browser agent and a browser extension to autonomously run web-based tasks inside our customers’ work applications. Today, it’s used for two key workflows:

User login: Automating user sign-in to work accounts to give security teams visibility and policy enforcement.

Lifecycle: Completing admin tasks inside applications (e.g., creating users) to save time, reduce human error, and tighten access control.

Our platform lets non-technical users configure these workflows for any application. We are working with companies ranging from decacorn financial services scale-ups to public insurance companies.

Their employees depend on Aglide to access mission-critical applications - from everyday SaaS tools to corporate bank accounts; while their security teams count on it to maintain compliance and defend against attackers - including, at times, state-sponsored threats.

What you’ll be building

End-to-end encrypted infrastructure: Owning and evolving the systems that keep sensitive customer data secure — across our backend, on-device environment, and browser extension.

Security architecture and threat modelling: Identifying vulnerabilities across the stack and designing systems that are resilient against real-world attack vectors, including those from sophisticated and state-sponsored actors.

Compliance and audit tooling: Building the internal controls and logging infrastructure that support SOC 2 and other compliance frameworks our enterprise customers require.

Platform controls and analytics: Giving customers more visibility and control over how their automations run — and giving our team the observability to detect and respond to anomalies.

Secure product features: Contributing full-stack across our dashboard, desktop app, and backend to ship features that embed security into the product experience, not just the infrastructure.

How you’ll build it

Independently and confidently: You’ll have significant ownership and autonomy - meaningfully shaping our priorities through the roadmap you influence and the problems you choose to solve.

Inventing the playbook: We're one of the few companies running browser-using agents for mission-critical work - and that comes with novel security challenges. You’ll help us maintain the reputation we have for our commitment to security in every product decision.

Across the stack: You’ll ship by contributing across everything - the dashboard, desktop app, backend services, and IaC configurations - with a security lens at every layer.

With high commitment: You’ll go from problem identified to solution shipped in days, even if it means working long nights and weekends.

The skills we’re looking for

Must-have

• 3+ years software experience: Looking for people who have built production software for real users, with meaningful exposure to security-sensitive environments.
• Strong security fundamentals: A deep understanding of applied cryptography, zero-trust principles, secure software development, and common vulnerability classes (e.g. OWASP Top 10).
• Excellent debugging and systems thinking: Browser automation is messy, and our workflows run on end-user devices with end-to-end encrypted data - tracing a security issue requires understanding the whole system.
• Desire for ownership: One engineer is responsible end-to-end - meeting a customer, diagnosing issues, designing a fix, and shipping to production (sometimes within a week).
