Role
Who you are
- If you’re driven to solve real-world problems with bold technology, we’d love to meet you
What the job involves
- 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
Our take
While the NFT space is often one that is enticing to investors and traders, there are persistent issues with fraud in the market. Cybercriminals are able to pass off any image as their own intellectual property, and while NFT marketplaces do abide by copyright laws this kind of fraud can be hard to spot before money changes hands. The damage to a brand's reputation and customer trust can be hard to rectify.
Doppel exists to solve this problem. Using an AI model trained to spot fraud and IP violations, it indexes NFT data across most of the major blockchains and flags potentially fraudulent NFTs. Trusted by Opensea, Dapper and numerous other marketplaces, Doppel scans over 1.5 million NFTs daily and has identified over 100,000 threats in the marketplace.
Doppel has raised significant funding, its 2025 round aimed at accelerating product innovation and expanding its capabilities beyond NFT fraud detection into broader social engineering defense. As AI-driven scams become more sophisticated, the company is ready as a multi-channel security platform, helping organizations detect, prevent, and respond to threats across digital environments.
