About the role

Security-focused engineer protecting a fast-moving fintech environment by turning production signals into detections, response, and hardening initiatives; collaborates with Product, Platform, and Engineering teams to detect, respond to, and prevent security incidents.

Responsibilities

  • Build and tune detections, alerts, and monitoring workflows across cloud, application, identity, and edge environments.
  • Review traffic patterns across APIs, authentication flows, and WAF telemetry to identify malicious activity, abuse patterns, and anomalous behavior.
  • Use AI responsibly as a force multiplier for triage, analysis, and workflow automation, while helping define guardrails for AI-enabled systems.
  • Help operate OnePay's vulnerability management program by triaging, prioritizing, and driving remediation for findings from Wiz, vulnerability scanning, and related workflows.
  • Develop Python-based tooling and automation to improve investigations, enrichment, response, and operational scale.
  • Partner with Product Security to translate threat models, security reviews, and product risks into production detections and response playbooks.
  • Investigate security events end to end, including triage, scoping, containment support, and follow-through on remediation.
  • Support vulnerability management and operational security practices in ways that align with PCI and SOC 2 expectations.
  • Participate in proactive threat hunting, detection improvement, and a 24x7 security incident response on-call rotation.

Qualifications

  • 5+ years of experience in information security, threat detection, security operations, detection engineering, or incident response, ideally in a cloud-native or product-focused environment.
  • Strong experience investigating suspicious activity in web, API, authentication, and infrastructure telemetry, with the ability to distinguish attacker behavior from normal production noise.
  • Demonstrated ability to review traffic and event patterns for signs of malicious activity, fraud, account abuse, credential attacks, reconnaissance, and exploitation attempts.
  • Strong Python programming skills and the ability to write maintainable code for automation, enrichment, analysis, and security operations tooling.
  • Experience building and tuning detections in a SIEM or detection platform and working with observability and logging systems such as CloudWatch, Datadog, or similar platforms.
  • Experience operating or supporting a vulnerability management program, including triage, prioritization, remediation tracking, and stakeholder coordination.
  • Familiarity with cloud and application security findings from platforms such as Wiz, including CNAPP, runtime, code, and vulnerability scanning use cases.
  • Experience with at least one major cloud provider, preferably AWS.
  • Working knowledge of identity and access systems, modern authentication flows, and the security implications of internet-facing applications and APIs.
  • Strong understanding of threat modeling, risk prioritization, and practical security controls across applications, infrastructure, and cloud environments.
  • Practical experience using AI tools in security workflows, along with sound judgment about AI-specific risks such as prompt injection, data leakage, excessive tool access, and weak auditability.
  • Excellent analytical, communication, and cross-functional collaboration skills, especially in environments where security needs to move quickly with product and engineering teams.
  • Drive and proactivity - everyone here is a builder and executor.
