About E2B

E2B is a fast-growing Series A startup with over $37M in funding and 8-figure revenue. We are building the Agent Cloud and power the infrastructure behind AI labs and some of the most widely used consumer and enterprise agents, including Manus, Genspark, Lindy, Groq, and Artificial Analysis. Our team includes original authors of Firecracker, the AWS microVM technology powering Lambda, along with alumni of Cognition, JetBrains, Zapier, and Wish.

About the Role

As E2B’s first engineer responsible for Trust & Safety, you’ll own and develop systems that protect our platform and customers from fraud and abuse. Your work will span payment fraud, account abuse, and misuse of compute resources, performing investigations and building detections using automation to respond.

You’ll have room to shape how we approach trust and safety as the platform grows. This is a hands-on role that combines data analysis, security investigations, and engineering. You’ll turn investigation findings into stronger detections, tools, and response processes while adapting to new patterns of abuse.

Responsibilities include:

• Build and improve detections for payment fraud, account abuse, and misuse of free credits.

• Investigate third-party abuse reports, evaluate the evidence, and take appropriate action.

• Analyze logs, query data, and connect activity across systems to understand patterns of abuse.

• Build tools and automation that help us detect, investigate, and mitigate abuse more effectively.

• Shape our trust and safety policies and response processes, balancing effective enforcement with the needs of legitimate customers.

What We’re Looking For

• Experience in trust and safety, abuse prevention, or risk with a security focus, including hands-on investigation and mitigation.

• Strong analytical skills and the ability to work with logs, query data, and reason through ambiguous activity.

• The engineering ability to turn investigations into practical detections, tools, and automation. We use Go, but prior Go experience isn’t required.

• An understanding of malicious traffic and attacks, with the judgment to evaluate abuse reports and decide how to respond.

• Experience owning problems from investigation through implementation, with the independence to build an approach as well as operate it.

Bonus Points For:

• Experience building abuse prevention systems at a startup or growing technology company.

• Experience handling fraud or abuse on a cloud infrastructure or self-service platform.
