Job description

Why Join Doppel

Doppel is built to outsmart one of the greatest 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.

What We're Building

We're building the AI‑native social engineering defense platform. This means designing scalable systems that monitor billions of domains, social media accounts, apps, dark‑web forums, 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 out the infrastructure required to rapidly scale up our engineering organization. A few examples of the work we’ve done recently:

• Built self‑hosted Elasticsearch infrastructure on Kubernetes, enabling real‑time search across millions of alerts and associated metadata.
• Defined core infrastructure using Terraform (IaC), allowing reproducible, version‑controlled environments and faster onboarding for new engineers.
• Stood up a dedicated staging environment, enabling safer releases, feature validation, and automated integration testing before production rollouts.
• Introduced observability and tracing (metrics, logging, distributed tracing), improving our ability to debug performance issues and maintain reliability at scale.

What We Offer

• 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 at scale. We 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. 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 world‑recognised brands, Doppel is growing fast. If you’re driven to solve real‑world problems with bold technology, we’d love to meet you.
