Summary
What you’ll impact
The senior security engineer will protect the organization's members by proactively identifying and remediating security weaknesses across AI systems, infrastructure, and applications.

Responsibilities
What you'll do
- You will be the person who keeps our members' financial lives safe.
- You will think like an attacker so we can build like defenders.
- You will probe our AI systems, infrastructure, and applications for weaknesses before anyone else can find them.
- When you find something, you will work directly with engineers to fix it.
- When you see a gap in how we detect or respond to threats, you will close it yourself.
- You will help us think about what's next.
- You will be the person figuring out what those threats actually look like for a fintech company and what we need to do about them.
- You will build automated tools to scale what you do.
- You will contribute to how we measure security as a program.
