Job description
At Bolster, you'll be part of the team protecting major global brands from phishing, impersonation, and online fraud campaigns targeting their users and employees. You'll work in a highly dynamic environment investigating suspicious domains and websites, validating real-world threats, and pursuing takedown actions during active proof-of-concept (POC) evaluations. This role supports Sales and Solutions Engineering by uncovering and confirming malicious activity, performing threat hunting, and helping demonstrate platform effectiveness by supporting takedowns. It is a strong opportunity to join a small and nimble team and contribute to the continued growth of Bolster's protection platform

Responsibilities

  • Review and assess emerging phishing, impersonation, and online fraud threats targeting Bolster's prospects.
  • Identify and pursue takedowns for malicious content across web, social media platforms, and mobile application stores, including impersonation accounts, fraudulent applications, and related abuse.
  • Perform targeted threat hunting to identify malicious domains, credential harvesting sites, fake login portals, and related attacker infrastructure across multiple modules.
  • Use OSINT tools and investigative techniques (WHOIS, DNS records, certificate transparency, search-based discovery, and infrastructure pivoting) to enrich findings and uncover related malicious activity.
  • Analyze suspicious websites, hosting infrastructure, DNS records, redirects, and related artifacts to detect attack patterns and emerging abuse trends.
  • Pursue takedown actions during active proof-of-concept (POC) evaluations and track each case through successful remediation.
  • Coordinate with registrars, hosting providers, and relevant abuse contacts to drive timely enforcement actions.
  • Monitor previously reported malicious infrastructure to confirm suspension and identify re-registration, reactivation, or attacker evasion attempts.
  • Support the Sales team with technical validation and threat intelligence during active POCs and evaluations.
  • Generate periodic and ad-hoc reports highlighting threat activity, detection insights, and remediation outcomes.

    • Qualifications

  • 2 years of experience in trust & safety or brand protection, with a focus on Pre-Sales.
  • Well versed with phishing, impersonation, credential harvesting, and online fraud activity, including investigative and reporting workflows.
  • Experience supporting technical evaluations, proof-of-concepts (POCs), or internal presales efforts is strongly preferred.
  • Understanding of internet infrastructure, including domains, DNS, hosting providers, redirects, and attacker infrastructure.
  • Knowledge of security and fraud detection principles and common attacker tactics, techniques, and procedures.
  • Self-motivated and detail-oriented with the ability to work independently as well as collaboratively.
  • Strong analytical and investigative mindset, including problem-solving and hypothesis-driven investigation.
  • Strong written and verbal communication skills with the ability to clearly document findings and summarize technical information internally.
  • Security certifications (Security , GSEC, or similar) are a plus.
  • Willingness and openness to assist with time-sensitive investigations aligned with active presales evaluations or critical incidents.
