Job Description
Location: Bratislava, Slovakia
Employment: Full-time | Office-first with a flexible hybrid schedule
Language: Fluency in Ukrainian or Russian is required
Role profile: This is a hands-on platform engineering role with security ownership - not a pure compliance position and not a standalone penetration-testing role.
About the Role
We are building our own iGaming product for Tier-1 markets and are looking for a Platform Security Engineer / DevSecOps to join our engineering team in Bratislava.
We are a Ukrainian marketing group with more than four years of experience in iGaming. During this time, we have grown to a team of over 250 professionals and built a strong in-house ecosystem. We are now entering a new stage of growth: developing our own iGaming platform with a core team and technical roadmap already in place.
You will work alongside our DevOps/SRE and engineering teams. Your role combines hands-on AWS and Kubernetes platform work with cloud security, secure delivery, detection engineering, incident readiness, and ATT&CK-based adversary emulation. You will help us build security into the platform from the start instead of attaching it as a PDF shortly before launch.
Key Responsibilities
Platform Engineering & Reliability
- Design, build, and operate our AWS and Kubernetes platform together with the DevOps/SRE team.
- Maintain infrastructure as code, CI/CD pipelines, environments, secrets, and deployment workflows.
- Improve platform reliability, observability, scalability, backup, recovery, and production readiness.
- Participate in platform on-call, incident response, root-cause analysis, and continuous operational improvement.
- Create reusable platform standards that help engineering teams ship safely and consistently.
Security Engineering
- Own the cloud and Kubernetes security baseline, including IAM, network boundaries, secrets, audit logging, container security, and privileged access.
- Build security controls into the software delivery lifecycle using SAST, SCA, secret scanning, IaC scanning, container scanning, and policy gates.
- Lead threat modelling for critical areas such as authentication, wallet and ledger, payments, game-provider integrations, callbacks, and backoffice privileges.
- Use OWASP ASVS to define practical application-security requirements and verification criteria with Tech Leads and developers.
- Establish vulnerability-management processes, severity rules, remediation SLAs, evidence, and retesting.
- Develop security monitoring, detection logic, incident playbooks, and security exercises using available cloud, infrastructure, and application telemetry.
- Coordinate external penetration tests, define the scope and rules of engagement, triage findings, and drive remediation through formal retesting.
Purple Teaming & Security Automation
- Design ATT&CK-mapped adversary-emulation and purple-team scenarios based on real risks to our platform.
- Use or integrate tools such as MITRE CALDERA and Atomic Red Team for controlled security validation.
- Work with developers acting as Security Champions to turn findings into controls, tests, detections, and regression coverage.
- Help build a small AI-assisted internal platform for threat-model support, control mapping, scenario management, evidence collection, remediation tracking, and reporting.
- Ensure offensive testing is authorised, scoped, auditable, and safe for the target environment.

You Will Be a Great Fit If You Have
- Strong commercial experience in DevOps, Platform Engineering, SRE, Cloud Security, or DevSecOps.
- Hands-on experience with AWS, Kubernetes, Docker, Linux, networking, and infrastructure as code.
- Practical experience with CI/CD, observability, secrets management, IAM, and production incident response.
- A solid understanding of cloud, container, API, and application-security risks.
- Experience implementing security scanning and vulnerability-management processes in engineering workflows.
- The ability to read code, understand service architecture, and work directly with backend and frontend engineers.
- A pragmatic engineering mindset: you can balance security, reliability, delivery speed, and business risk.
- Good communication skills and the ability to explain risks and remediation clearly to both technical and non-technical stakeholders.
- Fluency in Ukrainian or Russian, plus working English.
Nice to Have
- Experience in iGaming, fintech, payments, high-risk platforms, or other regulated environments.
- Experience with wallet/ledger systems, payment providers, game providers, KYC/AML, or backoffice security.
- Hands-on knowledge of OWASP ASVS, threat modelling, MITRE ATT&CK, CALDERA, or Atomic Red Team.
- Experience leading purple-team exercises, detection engineering, security incident simulations, or external pentest remediation.
- Knowledge of Kafka or RabbitMQ, PostgreSQL, Redis, microservices, and Node.js/NestJS environments.
- Experience using modern AI-assisted engineering or security tools and the judgement to apply them safely.
- Relevant AWS, Kubernetes, security, or offensive-security certifications are welcome, but practical experience matters more.
What Success Looks Like in the First 90 Days
First 30 days
Understand the platform and threat model; complete the initial service/access inventory; identify crown jewels and critical launch risks; agree the security backlog and external pentest plan.
Days 31-60
Implement priority cloud/Kubernetes hardening and delivery-pipeline controls; establish ASVS-based requirements and threat models for critical services; validate security telemetry and incident paths.
Discover our full range of relocation jobs with comprehensive support packages to help you relocate and settle in your new location.
Days 61-90
Run the first focused purple-team campaign; coordinate the pre-launch pentest; drive remediation and retesting; publish launch-readiness evidence and the next-quarter roadmap.
