Senior DevOps Engineer

Ciklum is looking for a Senior DevOps Engineer to join our team full-time in Bulgaria.

We are a custom product engineering company that supports both multinational organizations and scaling startups to solve their most complex business challenges. With a global team of over 4,000 highly skilled developers, consultants, analysts and product owners, we engineer technology that redefines industries and shapes the way people live.

About the role:

As a Senior DevOps Engineer, become a part of a cross-functional development team engineering experiences of tomorrow.

Our client's infrastructure powers millions of live sports events worldwide - from raw video capture at remote venues to real-time stream delivery and ML-driven monetization. As a DevOps & Platform Engineer, you will be a core contributor to the reliability, scalability, and operational excellence of our cloud platform.
You'll work inside a self-service, pod-based engineering model where your job is to build the platforms, pipelines, and guardrails that let product teams ship independently - at high velocity and with full operational ownership. This is a high-autonomy, high-impact individual contributor role with a clear technical growth path.

Responsibilities:

• Build and maintain GitOps-based delivery pipelines (ArgoCD) so product pods deploy safely without DevOps intervention
• Design and evolve self-service tooling - golden paths, deployment templates, scaffolding - that reduce pod dependency on the platform team
• Implement deployment safety guardrails: config diffing, change ownership, rollout strategies, and audit trails
• Adopt industry-leading AI tools and agentic workflows to accelerate development, automation, and operational delivery

Requirements:

• 5+ years in infrastructure, DevOps, or platform engineering roles
• Production-grade Kubernetes experience: EKS/GKE, GitOps (ArgoCD/Flux), service mesh, multi-tenant cluster operations, resource management
• Deep hands-on GitOps and CI/CD: ArgoCD or Flux, Kustomize/Helm, rollout strategies, deployment safety, change ownership, audit trails
• AWS platform depth: EC2, EKS, S3, CloudFront, IAM/IRSA, VPC networking, RDS, cost optimization levers
• Platform engineering orientation - you think in platforms and self-service, not one-off scripts or manual runbooks
• AI-first approach - actively uses AI tools to accelerate development and operations; not just aware of them, but fluent
• Ownership mentality - own outcomes end-to-end, escalate only when truly blocked, and translate infrastructure complexity into business impact
• People leadership skills, including mentoring and developing engineers, as well as conducting technical interviews

Desirable:

• GCP experience (GKE, GCS, Cloud Run) or hybrid multi-cloud operations
• Video streaming infrastructure: HLS, RTMP, CDN optimization, live video pipelines
• FinOps / cost optimization: cost attribution, right-sizing, storage lifecycle policies
• Development background (Python, Go, Node.js, or similar)

What’s in it for you?

• Regular salary reviews based on performance
• Corporate events: webinars, offline parties, and meetups
• Internal Mobility Program
• Tailored education path (including full access to Udemy, certifications, etc.)
• 25 paid days off: 20 business days of vacation per calendar year + 5 undocumented sick leave days
• Additional health insurance
• 100% company-covered Multisport card, with discounts available for family members
