Lead Security Engineer (DevSecOps & Compliance)

Join the company as a Lead Security Engineer and help us strengthen and scale security across our products and infrastructure.

This role combines high ownership with hands-on engineering. You’ll lead our security direction together with our DevSecOps / Security Engineer: securing our AWS environment, closing security tasks yourself, and owning our SOC 2 and ISO 27001 compliance. You’ll work closely with our Principal System Architect and the Platform, DevOps, and Backend teams as a trusted partner with real authority over technical decisions from a security perspective.

About Us

The company is the agentic AI platform for creating, launching, and scaling paid ads.

The next big step: a B2B solution for large marketing teams and enterprise clients — workflows, creative analytics, and full control over campaigns across the whole team. For companies where performance marketing already runs at scale and needs more efficiency and automation.

What You’ll Do

• Own compliance initiatives (SOC 2, ISO 27001, CASA): implement controls, prepare evidence, and work with auditors;

• Build security into CI/CD: SAST, DAST, SCA, secrets scanning, and infrastructure-as-code checks;

• Run incident response and set up monitoring and alerting;

• Define and prioritize security initiatives and own the security roadmap;

• Review architecture decisions and code from a security perspective;

• Support B2B clients with security questions, reviews, and due diligence.

• 7+ years of experience in DevOps, Platform, or infrastructure engineering, including at least 4 years focused on security (DevSecOps, Cloud Security, or Security Engineer);

• Hands-on experience with both SOC 2 and ISO 27001: preparing for, passing, or maintaining audits, understanding the requirements behind each control, and working with auditors;

• Strong hands-on experience with AWS and infrastructure as code using Terraform;

• Proven experience finding and fixing vulnerabilities and handling security incidents;

• Experience leading engineers or acting as a technical lead;

• AWS Professional-level certification (a security-focused Associate certification may also be considered);

• Upper-Intermediate (B2+) English or higher;

• Fluent Ukrainian.

Nice to Have

• Backend development background (Node.js / TypeScript, Java, C#/.NET, Go, or Python), or a career path from backend to DevOps/Platform to Security;

• Experience with CASA assessments;

• Experience implementing GDPR and/or CCPA (CPRA) requirements;

• Understanding of HIPAA or PCI DSS;

• Other security certifications (CISSP, OSCP, CKS) or GCP certifications.
