JOB DESCRIPTION

At eBay, we're more than a global ecommerce leader — we’re changing the way the world shops and sells. Our platform empowers millions of buyers and sellers in more than 190 markets around the world. We’re committed to pushing boundaries and leaving our mark as we reinvent the future of ecommerce for enthusiasts.

Our customers are our compass, authenticity thrives, bold ideas are welcome, and everyone can bring their unique selves to work — every day. We're in this together, sustaining the future of our customers, our company, and our planet.

Join a team of passionate thinkers, innovators, and dreamers — and help us connect people and build communities to create economic opportunity for all.

About the team and the role

At eBay, we build systems that protect customers from cybercrime and abuse. This team turns cybercrime research into production-grade signals, automations, services, and protections. The work spans off-platform cybercrime discovery and on-platform prevention, with a strong emphasis on engineering systems that move quickly from insight to action.

We are hiring a Full Stack Cybercrime Engineer to build and deploy the systems that help identify, investigate, and disrupt cybercrime targeting eBay and its customers.

This is an engineering-led role. We are looking for a strong software engineer who can build production systems in Python, Java, and SQL, operate effectively in the cloud, and ship reliable capabilities at speed.

At the same time, this role requires a critical security research mindset. You need to think like an attacker, understand how cybercrime campaigns work, and apply that mindset to the design of better signals, automations, workflows, and protections. This is not a pure research role, but strong security research instincts are essential.

We also expect Agentic Engineering and AI capability to be a core strength. You should be able to design and build agentic systems, AI-enabled workflows, and autonomous or semi-autonomous tooling that improves the speed, scale, and quality of cybercrime protections.

What you will do

Build production systems in Python, Java, and SQL that detect, investigate, and respond to cybercrime and abuse.
Design and deploy agentic systems, AI-powered workflows, and automation tooling for cybercrime research, enrichment, and protection.
Build services, APIs, pipelines, and internal tools that convert cybercrime intelligence into scalable customer protections.
Investigate phishing, brand abuse, digital identity crime, and related cybercrime patterns, then translate findings into durable engineering solutions.
Develop and improve signals, decisioning logic, and protection workflows that measurably reduce abuse and improve response speed.
Work with cloud technologies and distributed systems to deploy reliable, secure, and scalable capabilities.
Partner with security, product, and engineering teams to move from cybercime identification to shipped protection with minimal handoffs.
Own systems end to end: design, build, test, deploy, monitor, and improve.
Maintain a high quality bar, including rapid response to production issues and strong operational discipline.

What you will accomplish:

You build systems that shorten the time from cybercime discovery to deployed protection.
You deliver engineering solutions that improve prevention, identification, disruption, or remediation at scale.
You apply a security research mindset to uncover attacker behavior and convert those insights into production capabilities.
You build AI-native and agentic capabilities that reduce manual effort and improve speed, coverage, and consistency.
You ship reliable systems with strong security, quality, and operational ownership.

What you will bring:

Bachelor’s degree in Computer Science, Engineering, Security, or a related technical field, or equivalent practical experience.
Strong software engineering experience building and operating production systems.
Strong coding skills in Python and Java.
Strong SQL skills.
Hands-on experience with cloud technologies and modern distributed systems.
Experience building APIs, backend services, pipelines, automation tooling, or data-driven applications in production.
Experience debugging, monitoring, and improving systems in production.
Ability to translate ambiguous problems into concrete technical solutions.

Experience in security engineering, cybercrime investigations, intelligence, trust and safety, fraud, abuse prevention, or adversarial research.
A strong security research / hacker mindset: curiosity, technical depth, and the ability to understand attacker behavior, test assumptions, and identify practical weaknesses or opportunities for disruption.
Experience investigating phishing, impersonation, credential theft, brand abuse, or digital identity attacks.
Experience designing and building agentic systems, AI workflows, LLM-enabled tooling, or autonomous research and response capabilities.
Experience building detection systems, enrichment pipelines, or automated investigative workflows.
Experience working in fast-moving environments where engineers own delivery from concept through production.
