Why Join Doppel

Doppel is built to outsmart one of the great threats AI presents: mass‑manufactured social engineering. Countless scams, deepfakes, and other social engineering attacks are surging across every digital channel: websites, social media, ads, encrypted messaging apps, mobile, and more. Our mission is simple but bold: make the internet a safer place by outsmarting the world's fastest‑evolving digital threats.

Backed by a16z and Bessemer and trusted by some of the world's most recognized brands (OpenAI, United Airlines, Coinbase, etc.), Doppel is growing fast. If you're driven to solve real‑world problems with bold technology, we'd love to meet you.

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 backend engineer to build and scale an automated system to manage a variety of Security Analyst tasks. We aim to verify and neutralize threats in minutes using AI‑driven automation. A few examples of the work we've done recently:

• Built a sophisticated LLM engine to reduce verification workloads by 4x for the highest volume product line, which will enable faster takedowns at scale
• Built a QA & data labeling tool to close the feedback loop with human analysts, ML models, and LLM agents

As part of our Autopilot team, you'll:

• Play a critical role in building systems that protect billions of people from AI‑generated scams and general digital harm
• Have complete end‑to‑end ownership – from directly collecting product requirements to continuously evaluating and iterating on shipped releases
• Mentor junior engineers, foster a high‑performing team culture, and shape the team roadmap

Simulation Team

We're looking for an experienced fullstack engineer to help build out our new Simulation product. 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 what we built and why.

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

✈️ Quarterly team offsites

✨ Enjoy monthly in‑person dinners, happy hours, and social activities (Exploratorium, Valkyries game, etc.)
