• Collaborate with development, infrastructure, and security teams to design, build, and maintain reliable and scalable systems; • Participate in planning and executing load, chaos, and failover tests, focusing on risk mitigation and identification of bottlenecks; • Develop and maintain automation tools for monitoring, deployment, rollback, and incident response; • Monitor and respond to critical incidents, conducting root cause analysis (RCA) and proposing preventive actions; • Support the evolution of CI/CD processes, infrastructure as code (IaC), and security; • Lead automation, observability, and performance initiatives for critical systems; • Design, implement, and evolve monitoring, metrics, distributed tracing, and logging solutions; • Conduct incident reviews (postmortems) with root cause analysis and structured action plans; • Identify and apply continuous improvements to SLOs, SLIs, and SLAs; • Act as a focal point for failure mitigation, recovery, and continuity plans; • Drive a culture of reliability and resilience across the organization; • Mentor junior and mid-level professionals, promoting technical training and best practices.

• Establish the DevSecOps function at Playson, defining best practices and security standards across the Platform Tribe. • Integrate security into CI/CD pipelines (SAST, DAST, dependency scanning, container scanning). • Harden infrastructure and runtime environments (Linux, Docker, Kubernetes/EKS, RBAC). • Design and enforce cloud security controls in AWS (IAM least-privilege, GuardDuty, Security Hub, encryption at rest/in transit). • Define and maintain IaC security policies (Terraform/Terragrunt, drift detection, policy-as-code). • Implement and manage secrets management solutions (Vault, AWS Secrets Manager). • Build centralized security monitoring & alerting (Datadog, ELK, CloudWatch, SIEM/SOAR). • Lead vulnerability management and threat modeling practices. • Automate workflows through scripting (Python, Bash). • Partner with backend, infrastructure, and platform engineers to embed security in design & delivery. • Contribute to compliance readiness (ISO 27001, GDPR, PCI-DSS). • Act as a security subject-matter expert, mentoring engineers and raising awareness. • Continuously evaluate and implement new security tools and approaches.

• Redefine how public funds reach the people who need them. • Serve as the primary architect of security posture. • Own the critical intersection of security and compliance. • Drive the continuous hardening and evolution of systems at every layer. • Ensure platform remains a fortress, maintaining the highest levels of trust with government partners. • Collaborate closely with DevOps, Engineering teams, and CISO.

• Ensure reliability, availability and performance of compute nodes running VMs • Analyze and debug Linux systems across user space and kernel space, understanding capabilities, limitations and trade-offs at each layer • Troubleshoot complex production issues involving CPU, memory, NUMA, cgroups and scheduling • Work hands-on with virtualization and containerization, primarily using QEMU/KVM and Linux-native technologies • Design and evolve observability as a core capability of the node layer: metrics, logs, traces, alerts, SLIs and SLOs • Lead incident response, root-cause analysis, and postmortems, driving long-term reliability improvements • Collaborate closely with platform, kernel/hypervisor, GPU and infrastructure teams to improve system design and operability.
