Role
Who you are
- Must-have: hands-on experience securing AI technologies, including at least one of:
- Deploying guardrails or sandboxes,
- Managing AI identities,
- Detecting or mitigating prompt injection,
- Running AI security reviews, or
- Implementing AI security tooling (built or bought)
- 3-6 years of experience
- We recognize that strong qualifications can come from both prior work experiences and lived experiences. We encourage you to apply to a role even if your experience doesn't fully match the job description. We are always looking for team members that will bring something unique to Plaid!
Desirable
- Experience at a frontier AI lab or on a security team defending production AI systems at scale
- Experience on a Infrastructure Security, Cloud Security, Platform Security, Corporate Security, Security Operations (SecOps), and/or Detection & Response team
- Software security review, SDLC, vulnerability discovery, and/or offensive security experience
What the job involves
- The Platform Security team (PlatSec) defends Plaid against attackers. We own laptop security, cloud security, AI security, detection and response, and red teaming. Right now we're in growth mode. AI has expanded Plaid's attack surface faster than most security teams can adapt, and we're building the guardrails, identity controls, and detection systems to keep pace without slowing the business down. If you like solving problems nobody's solved yet, this is that team
- You'll be Plaid's first line of defense on AI security. You'll review new AI technologies to find security risks before they ship, then design and implement the controls that close them. You'll build the guardrails, identity management, and detection systems that let Plaid use AI aggressively without getting burned
- Review AI systems and integrations for security risk before and after deployment
- Design and deploy guardrails, sandboxes, and other controls that contain what AI agents can do
- Build or implement systems to track and manage AI identities, so we know what access every AI has been granted and can balance risk with agility
- Detect and mitigate prompt injection across Plaid's AI surface area
- Run AI-focused security reviews and set the bar other teams build to
- Your impact: fewer AI-related incidents, faster AI shipping, and controls that scale. Plaid wants to be a leader in AI, internally and externally, and we can’t do that safely without you
Our take
Plaid builds infrastructure that allows consumers to interact with their bank account on the web through a number of third-party applications, like Venmo, Robinhood, Coinbase, Acorns and LendingClub.
Plaid has integrated with over 12,000 financial institutions in the US, Canada, the UK and Europe. And about a quarter of people living in North America with bank accounts have linked with Plaid through at least one of the hundreds of apps that leverage Plaid’s application program interfaces (APIs).
The platform allows companies to create financial services applications without having to hire their own team of engineers to build out a tool that connects apps to its users’ bank accounts. This is very valuable in a world where there are increasing number of fintechs, so the demand for Plaid's services are only going to grow.
