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.

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, and more, and leverage AI agents to identify and neutralize digital threats.

We’re looking for an experienced backend engineer to build out the infrastructure required to rapidly scale up our engineering organization. A few examples of the work we’ve done recently:

• Built a scalable data platform with a robust DBT transformation layer, enabling customers, engineers, and analysts to reliably model and query large‑scale event data, track key product metrics, and power customer‑facing analytics.
• Launched a flexible notification system, delivering timely, reliable alerts across Slack, email, and other channels for internal and customer‑facing use cases.
• Standardized core service patterns and shared business logic (auth, persistence, messaging), scaling them into reusable services that reduce duplication, ensure consistency, and enable product engineers to move faster as the company grows.

• 🚀 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

Doppel is the first platform built to dismantle digital deception  scan over 150 billion entities daily and deploy continuously adaptive AI SOC agents, paired with expert human analysts, to uncover and disrupt the infrastructure behind phishing, impersonation, and online fraud before attacks can spread. Our Threat Grid turns every customer signal into shared intelligence, making each disruption smarter, faster, and more effective.

We’re not just another cybersecurity company; we’re defining the future of social engineering defense, where trust is protected, and deception becomes unprofitable. Backed by top‑tier investors and trusted by some of the world’s most recognized brands, Doppel is growing fast. If you’re driven to solve real‑world problems with bold technology, we’d love to meet you.
