UPSTARS is a product IT company where both people and brands take off 🚀 Our main focus is tech solutions and B2B services for international clients. We launch award-winning iGaming projects that shine bright in industry rankings ✨

And yes — supporting a transparent, legal Ukrainian market is a must. That’s why we became the third company in Ukraine to receive a B2B license for providing iGaming services.

In 2026, we’re scaling fast — both projects and our dream team. So now we’re looking for a Middle Office Manager to join our Workplace Experience crew and help make magic happen.


✅ Main tasks

  • build a centralized Security Operations operating model: define areas of responsibility, process owners, SLAs, and processes for alert handling, incident management, escalations, post-incident reviews, and reporting;
  • design and implement the foundation for SIEM / Log Management: centralized log collection, logging requirements, log parsing and normalization, retention policies, access controls, log delivery monitoring, and audit-ready logging coverage;
  • build a detection engineering process: develop, maintain, and regularly review detection rules for authentication, IAM, cloud infrastructure, Kubernetes, Git, CI/CD, databases, endpoints, and application-level events;
  • develop the incident response process: create response playbooks for common security incidents, perform initial analysis, containment, eradication, recovery, evidence collection, timeline analysis, and implement post-incident improvements;
  • automate routine SecOps processes: ticket creation, alert enrichment, context collection, stakeholder notifications, device isolation, account blocking, and other response actions;
  • collaborate with Service Desk and IT teams to implement baseline endpoint security controls: MDM, disk encryption, firewalls, OS patching, device compliance, remote wipe, EDR / XDR or antivirus coverage, and controls for high-risk and unmanaged devices;
  • collaborate with Engineering, Platform, IT, Access Management, Legal / Compliance, and management teams on logging, incident response, endpoint controls, vulnerability management, policies, procedures, and audit evidence preparation.

💪 Mandatory requirements

  • 5+ years of hands-on experience in Security Operations / Security Engineering, with a focus on building or developing SecOps processes in production environments;
  • hands-on experience implementing or administering SIEM and log management solutions: log collection, normalization, parsing, retention management, event correlation, alerting, and dashboarding; experience with Elastic Security, Wazuh, Splunk, Datadog Security, or similar solutions;
  • experience working with cloud and infrastructure activity logs: AWS CloudTrail, GuardDuty, Security Hub, EKS Audit Logs, VPC Flow Logs, WAF logs, VPN logs, and authentication logs;
  • experience developing detection rules, correlation rules, and alerting logic for real-world security scenarios rather than relying solely on predefined templates; practical understanding of MITRE ATT&CK, common attack techniques, detection coverage, and the difference between noisy alerts and actionable alerts;
  • understanding of the incident response lifecycle: preparation, detection, initial analysis, containment, eradication, recovery, and post-incident review;
  • experience with EDR / XDR / antivirus solutions such as Bitdefender, CrowdStrike, Microsoft Defender, SentinelOne, or similar tools;
  • experience with MDM and endpoint security across macOS, Windows, or Linux: disk encryption, firewalls, OS patching, device compliance, and remote wipe;
  • practical understanding of authentication, authorization, IAM events, network security, and common attacker behavior patterns;
  • strong automation and scripting skills in Python, Bash, or Go for log processing, alert enrichment, API integrations, reporting, and incident response workflows;
  • ability to work independently, build processes from scratch, prioritize effectively, collaborate across teams, and communicate incidents or logging requirements clearly to engineers, management, and compliance teams.

🤞 Nice to have

  • experience in gambling, fintech, or other regulated industries;
  • hands-on experience with PCI DSS, particularly Requirements 10 and 12, audit logging, and incident response evidence preparation;
  • experience building SecOps / SOC processes from scratch or significantly improving existing processes;
  • experience with SOAR solutions or security automation platforms;
  • experience with Cloudflare Access, Zero Trust approaches, VPN security, or device posture checks;
  • experience with basic digital forensics, phishing response, endpoint timeline analysis, evidence preservation, email security logs, and investigation of user-reported security incidents.
