From the employer
Join Zeely 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:

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:

We’re not a startup searching for product-market fit — we’re a business with proven results and a clear understanding of what works.
What You’ll Do:
Secure our AWS-first cloud environment hands-on: IAM and access management, secrets, hardening, and network security;
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;
Find, prioritize, and fix vulnerabilities across our product and infrastructure, closing critical security tasks yourself;
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;
Set up security policies and processes, and guide the DevOps and Platform teams on implementation;
Support B2B clients with security questions, reviews, and due diligence.
What Do You Need to Join Us?
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.
Why It’s Worth Joining Us:
Security ownership at one of the world’s leading AI companies: Zeely is #22 in a16z’s Top 50 consumer AI apps by monthly revenue;
Security is a strategic priority for the company: a direct line to the C-level co-founders, real authority over technical decisions, and a strong voice in how the product is built;

A remote-first setup with offices in Warsaw and Kyiv;
