Security Software Engineer, Anti-Abuse/Trust & Safety (Global)

Accountabilities

• • Develop, implement, maintain, and improve security and anti-abuse capabilities within core product systems.
  • Partner closely with Trust & Safety engineering teams to define technical strategies, solve complex security challenges, and strengthen preventative controls.
  • Design systems that identify, mitigate, and prevent malicious, fraudulent, or abusive activity across the platform.
  • Participate in and lead code reviews for security-sensitive features, promoting strong engineering practices, maintainability, and code quality.
  • Support the development and refinement of machine learning models by helping collect, organize, and prepare high-quality training data.
  • Collaborate with engineering and other cross-functional teams to ensure new products and features are launched with appropriate security and anti-abuse protections.
  • Investigate security incidents, abuse reports, and emerging threats, identifying root causes and implementing effective remediation.
  • Monitor evolving security threats, fraud patterns, and anti-abuse techniques and translate relevant findings into practical platform improvements.
  • Implement and manage integrations with third-party security, fraud, identity, and anti-abuse products within production environments.
  • Contribute to threat intelligence and preventative security initiatives by anticipating potential attack vectors and designing controls before threats become widespread.
  • Adapt quickly across projects, technologies, and priorities while maintaining a strong balance between delivery speed, technical quality, and security.
  • Share knowledge with teammates and contribute constructively to a collaborative engineering culture through technical discussions and code reviews.

  Requirements

  • 5–8+ years of professional software engineering experience, with significant experience building and maintaining production software systems.
  • Experience with Ruby on Rails or a comparable MVC backend framework.
  • Strong understanding of full-stack web architectures and how applications and services behave in production environments.
  • Experience with modern testing frameworks such as Playwright, Cypress, Jest, Selenium, or RSpec.
  • Solid understanding of computer networking fundamentals, including subnetting, DNS, HTTP, and HTTPS protocols.
  • Practical experience with security and anti-abuse technologies such as WAF rules, Cloudflare, reCAPTCHA, and comparable protection systems.
  • Familiarity with threat intelligence feeds, fraud prevention, security platforms, KYC solutions, or enterprise security tools.
  • Strong analytical and problem-solving skills, with the ability to break complex security problems into manageable components and identify root causes.
  • A security-oriented or “hacker” mindset, with curiosity about how systems can be exploited and the ability to anticipate malicious behavior and attack vectors.
  • Demonstrated ability to think abstractly and creatively when addressing emerging or poorly defined security threats.
  • Strong technical judgment and a proven ability to take ownership of systems and projects over time.
  • Excellent written and verbal communication skills, including the ability to explain complex technical and security concepts to both technical and non-technical stakeholders.
  • Ability to collaborate effectively within a small, highly autonomous engineering team and contribute constructive feedback during technical discussions and code reviews.
  • Comfortable managing multiple priorities, switching contexts, and adapting to new technologies in a fast-moving environment.
  • A proactive, quality-focused approach with the resilience and persistence needed to solve difficult technical problems.
  • Ability to balance high engineering standards with pragmatism, speed, and delivery requirements.
