Role Overview

We’re hiring a Security Lead to own and drive our security function end-to-end, combining strategic direction with hands-on technical authority.

● Ensure appropriate logging and monitoring coverage

● Lead and coordinate security investigations when required

● Track remediation actions following incidents

● Continuously improve controls based on lessons learned

5. Penetration Testing & External Assessments

● Track findings to closure

● Strengthen internal controls based on test results

6. Regulatory Alignment (CIRO + SOC 2)

● Lead security readiness for CIRO requirements

● Drive SOC 2 preparation and evidence collection

● Maintain defensible documentation and policies

● Ensure implemented controls withstand audit scrutiny

● Partner with Engineering Directors to close compliance gaps

7. Third-Party & Vendor Risk Management

● Define and manage third-party risk assessment processes

● Evaluate the security posture of critical vendors

● Assess the security impact of new tools before adoption

● Define mitigation controls prior to integration

● Maintain vendor risk documentation aligned with regulatory expectations

8. Endpoint & Internal Controls

● Strengthen security controls on developer machines

● Define secure onboarding and off boarding processes

● Improve privileged access controls

● Ensure internal security practices align with regulatory expectations

Who you are:

● Understand IAM and least privilege principles

● Understand logging, monitoring, and alerting architecture

● Be comfortable reviewing infrastructure-as-code (Pulumi)

● Reason confidently about security architecture across infrastructure and application layers

● Be willing to deepen your technical capabilities where needed

● Have hands-on experience with SOC 2 or comparable audit processes

● Have experience in a regulated environment (fintech, financial services, or similar), ideally CIRO-regulated

● Have a strong understanding of risk management frameworks

● Influence and challenge cloud architecture decisions when needed

● Experience with AI tooling governance or AI-related security considerations is a strong plus
