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.
Here are some additional resources on and .
