Platform Engineer, Product Security
About The Position
People tell Flow things they'd never type into a search box. Their medical questions, their legal drafts, the fight with their husband. We're on the screen while they work, we hear the whole sentence, and millions of users and thousands of enterprises have entrusted us with their most confidential professional and personal messages. Wispr is built on a foundation of trust. Unlike most products, we carry a much deeper obligation to protect user data and build strong defenses against attacks and breaches. Why this is hard: agentic AI engineering brings speed, and it can open gaping security holes just as fast. Securing the product and user data against DDoS and breaches is a constant effort as we scale from millions of users to hundreds of millions, across mobile, web, desktop, wearables and whatever comes next.
Requirements
- You enjoy decompiling code and finding vulnerabilities.
- You have strong opinions about tradeoffs, and you're pragmatic about which battles matter.
- You care as much about the user journey as the threat model.
- You've naturally become the security person even though nobody asked you to.
- This job description excites you.
Responsibilities
- Own product security end to end, prioritizing threats and architecting defenses.
- Get into new surfaces early — design reviews where the design is still changing.
- Build security into the platform so the safe path is the easy one.
- Make the whole team better at this, without becoming the person everyone waits on.
Benefits
- Equity on employee-friendly terms, including early exercise and extended exercise windows with a combination of ISOs and RSUs.
- Health, dental and vision. We cover 100% of the premium on the Anthem Blue Cross Gold PPO, and 75% of premiums for dependents. (US)
- 401(k) with up to a 4% match. (US)
- 16 weeks of paid parental leave (12 weeks for non-birthing parent).
- Flexible time off and company holidays.
- All meals in the office, plus commuter benefits and relocation reimbursement if you’re moving to San Francisco.
- A high-spec laptop, monitor, and a whisper-friendly microphone.
- Regular team events and off-sites.
