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
Required
What We're Looking For
- 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
- Familiarity with fraud detection models and transaction risk monitoring
- Experience in Product Security and CI/CD Security
- CISSP, CISM, CISA, or equivalent certifications
What We Offer
- Competitive salary and benefits package.
- Equity in a rapidly growing company.
- Opportunity to work in a fast-paced startup at the forefront of fintech innovation.
- Opportunity to make a significant impact on global financial infrastructure.
- Collaborative work culture with emphasis on personal and professional growth.
