Security Officer

Join Zeely as a Security Officer and help us strengthen and scale security across our products and infrastructure.
You'll work closely with our engineering team, including a Security Engineer, as a trusted partner with real authority over technical decisions from a security perspective. As the company grows, you'll have the opportunity to build and lead a dedicated security team.
About Us:
Zeely is the agentic AI platform for creating, launching, and scaling paid ads.
Simply put: we've made the best AI solutions and marketing tools available to small and medium businesses — tools that used to be reserved for big brands with expensive marketing teams.
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.
A few numbers that speak for themselves:
- 4 years on the market — a stable, profitable company backed by international investors;
- 6× growth over the past year;
- 2,000,000+ businesses already use Zeely;
- #1 in its category in the US market;
- 200+ specialists on the team;
- Markets: US + worldwide.
What You'll Do:
- Assess our infrastructure and product from a security perspective;
- Proactively identify, prevent, and help fix vulnerabilities across our product and infrastructure;
- Lead incident response and help defend against attacks in real time;
- Define and prioritize security initiatives and shape the security roadmap;
- Work hands-on: close security tickets yourself and collaborate closely with the DevOps and Platform teams on implementation;
- Integrate security into our development pipeline (SDLC / CI/CD);
- Drive compliance initiatives, mainly SOC 2 (Type 1) and CASA, and implement relevant ISO 27001 controls;
- Develop security policies, processes, and access management practices across our cloud infrastructure (AWS);
- Review architecture decisions and code from a security perspective;
- Support B2B clients with security-related questions, reviews, and due diligence.
What Do You Need to Join Us?

- Hands-on backend development background (Node.js / JavaScript / TypeScript, Java, or C#/.NET);
- Strong practical experience in DevOps and cloud infrastructure;
- Proven experience finding and fixing vulnerabilities and handling security incidents;
- AWS Professional-level certification (a security-focused Associate certification may also be considered);
- Hands-on experience implementing SOC 2 and/or ISO 27001 controls — owning the process end to end, not just maintaining existing policies;
- Experience with external security audits (Big Four experience is a plus);
- Upper-Intermediate (B2+) English or higher;
- Fluent Ukrainian.
Nice to Have:
- Experience with CASA assessments;
- Experience implementing GDPR and/or CCPA (CPRA) requirements;
