We are looking for a CISO to turn expertise, initiative, and bold thinking into real impact on the next generation of AI-driven financial crime detection.
As CISO, you will define and execute our global security strategy across both internal and product environments, serving as the primary security authority in front of customers, regulators, and auditors.
If you combine strong security leadership and cloud-native technical expertise with deep understanding of enterprise sales cycles and regulatory standards, and if you are motivated by directly influencing customer trust and enabling the world's largest financial institutions to adopt cutting-edge AI-driven solutions with confidence, we could be your next challenge.
Responsibilities:
Define and lead a comprehensive, business-aligned security program that supports growth while mitigating global risk.
Act as the primary interface with customer CISOs, auditors, and regulators, leading security discussions, due diligence processes, and enabling successful deal closures.
Partner with Engineering and DevOps to secure our cloud-native architecture across AWS, Azure, or GCP, including Kubernetes environments, ensuring enterprise-grade resilience.
Embed security-by-design across the development lifecycle, including AI and ML models and data pipelines.
Own and drive compliance with global standards including ISO 27001, SOC 2, NIST, GDPR, and DORA.
Oversee modern security tooling and practices across IAM, SIEM, DLP, CASB, CSPM, and emerging AI security domains.
Lead incident response, business continuity, and cyber resilience planning, including executive-level simulations and ransomware readiness.
Own vendor risk management and ensure end-to-end security resilience across the ecosystem.

We are looking for a hands-on Security Research Team Lead to own and scale our Security Research domain.
This is a foundational role in a small, highly technical team, focused on deep security research, algorithmic thinking, and leveraging AI to turn complex data into accurate, actionable security insights.
This role is not about people management by default - it is about technical leadership, ownership, and building scalable research capabilities that directly impact product and customer security.
Responsibilities:
Own and lead the Security Research domain through hands-on technical work.
Research security risks in SaaS and business applications, including permissions, identities, and access models.
Design and apply algorithmic approaches to analyze complex data structures and security risk surfaces.
Leverage AI-based techniques to work with large-scale data, improve accuracy, and automate research workflows.
Detect security flaws, misconfigurations, and systemic risks in SaaS environments.
Lead and support complex security investigations and customer-facing incident research.
Work closely with Product and Engineering to translate research findings into scalable product capabilities.
Technically mentor and support a small and growing research team.
Define research priorities and help shape how the team scales over time.

As a Security Operations & Automation, you'll be the hands-on architect of how Port detects, investigates, and responds to threats - built around AI agents and deep tooling integrations, not manual triage. You'll own incident response across corporate systems, workstations, and identity, unify alerts from every source - including cloud-originated signals that need a response - into a single SOAR/XDR fabric, and deploy AI agents to handle first-line investigation and response.

You'll work closely with IT and the Cloud Security team - taking the lead on investigation, triage, and response while they own the underlying cloud and SDLC architecture - and turn complex security signals into structured, AI-assisted, largely autonomous outcomes - fighting fire with fire.



Responsibilities

Architect and own Port's AI-driven detection and response stack, integrating SIEM, XDR, SOAR, EDR, and IAM into a single automated fabric rather than siloed tools.
Deploy and tune AI agents to handle first-line alert triage, enrichment, and investigation, with humans engaged only for true edge cases - manual L1 triage is the exception, not the default.
Build SOAR playbooks and integrations across the security and IT toolchain (endpoint, identity, ticketing, chat) so detection, enrichment, and remediation run automatically end to end - regardless of which system or platform an alert originates from.
Own the alert pipeline as a whole: unify signals from EDR, IAM, and other sources - including cloud and SaaS alerts surfaced by the Cloud Security team - into one triage and response workflow, so nothing falls through the cracks between tools.
Evaluate and integrate best-of-breed, AI-native security tools - SIEM, XDR, SOAR, EDR, email security, AI guardrails, ZTNA, and others - wiring each into the unified detection and response fabric rather than running them as siloed point solutions. Hands-on tool integration (APIs, connectors, log and telemetry ingestion) is a core skill for this role, not an occasional task.
Drive vulnerability and patch management across corporate systems and endpoints, automating prioritization and remediation workflows and coordinating with IT against strict SLAs.
Build and tune detection rules specific to Port's environment, treating detection as code and feeding AI-driven correlation across the XDR layer.
Maintain security dashboards (MTTD/MTTR, automation rate, % of alerts resolved without human touch) and report on how automation is cutting noise and response time.
