Product Security Engineer; Founding team

Overview

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.

Must-have

The skills we re looking for

• 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).

Nice To Have

• Experience with our stack:
  Type Script, Postgres, Electron (macOS/Windows/Linux), web automation, and browser extensions.
• Security experience:
