Full Stack Cybercime Operator

Location: Dublin Ireland
Employment Type: Full Time In Office
Company: eBay

About the team

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 cybercime discovery and on-platform prevention with a strong emphasis on engineering systems that move quickly from insight to action.

The role

We are hiring a Full Stack Cybercrime Operator 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 success looks like

Success in this role is defined by concrete outcomes:

• 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.

Minimum qualifications

• Bachelors 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.

Preferred qualifications

• 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.

What we are looking for

• A strong engineer first.

• Someone with a real security research mindset not just surface-level security interest.

• Someone who can think like a hacker and build like a product engineer.

• Someone comfortable using AI and agentic engineering as core tools not side experiments.

• Someone who takes ownership moves with urgency and ships high-quality systems.

Why join eBay

This is an opportunity to build high-impact security capabilities in a domain where the landscape changes constantly. You will work on systems that combine engineering cybercime research cloud infrastructure and AI-native automation to protect customers at scale. The direction of the team is toward building a cybercrime capability where automated systems continuously improve how cybercime is identified and protections are deployed.
