Doppel is building the future of social engineering defense. Our AI-native platform uses agentic AI to protect executives, employees, customers, and brands from phishing, impersonation, fraud, and other AI-powered threats across digital channels. We help some of the world’s most recognized brands detect and dismantle attacker infrastructure while strengthening employee resilience through threat-informed training and simulation. By unifying Digital Risk Protection, Human Risk Management and Email Security, Doppel connects threats into a real-time intelligence graph to power faster disruption, smarter defense, and modern security awareness at scale.
Backed by leading investors including Andreessen Horowitz and Bessemer Venture Partners, and trusted by leading enterprises, Doppel is a rapidly growing Series C startup building the future of social engineering defense. Our team combines deep cybersecurity expertise, operational rigor, and startup velocity to solve some of the internet’s most urgent trust and safety challenges.
What We're Building
We're building the AI-native social engineering defense platform.
This means we're designing scalable systems that monitor billions of domains, social media accounts, apps, dark web forums, etc., and leverage AI agents to identify and neutralize digital threats.
What We're Looking For
We’re looking for an experienced fullstack engineer to help build out our new Simulation product. Simulation is a small, fast-moving team inside Doppel (a series C company backed by Bessemer and a16z) building an entirely new product line, think of it as a startup within a startup. We crossed 6 figures within a few months of launching and are on track to hit 1M ARR in Q4.
Our mission: to help companies proactively defend against the next wave of social-engineering attacks. We’re creating AI-powered phishing simulations that use large-language models and voice synthesis to mimic real-world threats - from hyper-personalized emails to high-fidelity “manager calls” that test and train enterprise security teams.
You’ll be joining a team led by ex-Meta and YC founders, already working with Fortune 100 customers. It’s the rare mix of startup-level growth and creativity with established-company backing and stability. The perfect place to move fast, ship real impact, and help define an emerging category.
We Only Just Recently Launched It But Market Traction Is Growing Extremely Fast And We Need People Excited To Jump And Do Whatever It Takes To Build What Our Customers Desperately Want. For Example
- Build out a “Cursor for phishing simulation” flow that lets users create simulations using natural language..
- Build out voice deepfakes that use AI to call employees pretending to be their co-worker.
What We Offer
A mission-driven culture with low ego, high ownership, deep customer obsession, and exceptional talent density
Free lunch and dinner in the office
Flexible PTO
Quarterly team offsites
