Security Operations Center(SOC) Engineer

About Us

OpenFX is on a mission to move money as freely as data, unrestricted by time zones, banking hours, or legacy systems. We are building the infrastructure that will power the next generation of cross-border payment systems for institutions. The team's execution has been exceptional, and we're scaling at a remarkable pace. Our stellar early team comes with experience in companies like J.P. Morgan, Goldman Sachs, FalconX, Paypal, Affirm, Polygon, Kraken, Nium & others. We're backed by Accel, Faction, NfX, Accomplice, and other top-tier investors.

Role Overview

OpenFX processes billions of dollars in transaction volume every month across global corridors, connecting banks, liquidity providers, and third-party systems in real time. As transaction volume and geographic footprint scale, so does our threat surface. We need a SOC Engineer who can build and own a high-performance security operations function—one that detects early, responds decisively, reduces systemic risk, and scales ahead of growth. In fintech, a delayed alert is money lost and a missed signal is reputational damage. Security must be operational, measurable, and deeply integrated into how we ship and scale.

Key Responsibilities

• Build and operationalize a fintech-grade SOC function with monitoring across cloud, infrastructure, identity, endpoints, and transaction systems
• Establish detection coverage aligned to MITRE ATT&CK and fraud threat models
• Lead incident response end-to-end: containment, eradication, recovery, and post-incident reviews with clear root cause analysis
• Minimize blast radius and reduce mean time to detect (MTTD) and respond (MTTR)
• Design high-signal alerting strategy to reduce noise and improve SIEM use cases, telemetry coverage, and correlation rules
• Define and track security KPIs and KRIs including detection coverage, false positive rate, and incident severity trends
• Integrate security review into new feature launches and ensure logging, telemetry, and auditability are designed upfront
• Align security monitoring with transaction flows, reconciliation pipelines, and money movement controls
• Detect abnormal patterns in account behavior, API misuse, and privilege escalation
• Hire, mentor, and level up analysts and detection engineers; define escalation paths and on-call processes
• Ensure SOC processes support ISO 27001, PCI DSS, NIST, and regulatory requirements with defensible evidence for audits

What We're Looking For

Required

• 8 to 12+ years in cybersecurity operations
• Proven experience building or maturing a SOC in a complex environment
• Deep experience in incident response and security investigations
• Hands-on experience with SIEM platforms and detection rule engineering
• Strong knowledge of cloud security (AWS/GCP/Azure), identity systems, and SaaS telemetry
• Experience defining KPIs, dashboards, and operational metrics
• Strong leadership and team management experience
• Ability to communicate risk clearly to executives and non-technical stakeholders

Preferred

• Experience in fintech, payments, or high-transaction financial systems
• Knowledge of SOC 2, ISO 27001, NIST, CIS
• Experience with EDR, SOAR, DLP, CASB, MDM, Email Security
