About SlotCatalog
 

SlotCatalog is a leading intelligence and data platform in the online casino industry. We serve both players and industry stakeholders by tracking slot games, providing performance insights, and managing large-scale structured data. The business is profitable and growing, with strong traction across both SEO and direct industry relationships. We are now expanding into regulated markets, direct media sales, and AI-powered tools.

What We’re Looking For
 

We’re hiring a Senior DevOps Engineer to take full ownership of SlotCatalog’s infrastructure, reliability, and DevOps practices at a critical stage of growth.
 

Until now, infrastructure and operational decisions have been largely founder-led and handled in an ad-hoc manner. This role will become the primary technical owner of production reliability and platform stability, responsible for building a mature, scalable, and well-documented DevOps function.
 

You will lead the transition from a founder-managed setup to a structured, production-grade DevOps organization, defining standards, processes, and long-term architecture. This is a hands-on leadership role: you will both design and implement solutions, while setting the direction for how infrastructure, CI/CD, security, and observability are built and maintained.
 

You will act as the key bridge between Engineering, Product, and Leadership, ensuring that delivery speed, system reliability, and security are balanced in a sustainable way. The role requires strong technical depth, ownership mindset, and the ability to make architectural decisions that will support the company’s growth over the next years.

Responsibilities
 

Infrastructure & Reliability Ownership:

• Own the full lifecycle of production infrastructure and environments.
• Define and maintain standards for availability, scalability, and disaster recovery.
• Lead the migration and stabilization of infrastructure from DigitalOcean/Hetzner to AWS.

CI/CD & Automation:

• Architect and own CI/CD pipelines (GitlabCI) and deployment strategies.
• Design and implement automation for provisioning, deployment, scaling, and recovery using Terraform, Helm, ArgoCD.

Kubernetes & Platform Engineering:

• Own Kubernetes clusters (EKS): architecture, security, networking, scaling, and upgrades.
• Define best practices for deployments, ingress, secrets management, and service reliability.

Observability & Incident Management:

• Own monitoring, logging, and alerting stack (Prometheus, Grafana, Loki).
• Define SLOs/SLAs, alerting policies, and incident response processes.
• Lead post-incident reviews and reliability improvements.

Security & Access Management:

• Own access control, IAM, secrets, network security, SSL/TLS, and compliance basics.
• Ensure secure-by-design infrastructure and CI/CD pipelines.

Collaboration & Technical Leadership:

• Act as DevOps authority for backend, data, and product teams.
• Participate in architecture discussions and release planning.
• Mentor engineers in infrastructure and reliability best practices.
• Establish documentation, runbooks, and operational standards.

Requirements & Skills

• 5+ years of DevOps / Platform Engineering experience, including:
• At least 2+ years owning AWS production environments.
• Strong System Administration background (Linux, networking, access control).
• Deep expertise in Kubernetes (EKS, networking, autoscaling, security, ingress, secrets).
• Hands-on experience with:
• Docker
• GitlabCI
• Terraform, Helm, ArgoCD
• Strong knowledge of:
• Prometheus, Grafana, Loki
• High-availability and fault-tolerant architectures
• Solid understanding of:
• Networking, security, IAM, VPN, firewalls, SSL/TLS
• Experience operating and tuning MySQL/MariaDB in cloud environments.
• Understanding of backend stacks (PHP) to support environment design and deployment optimization.
• Proven ownership mindset: ability to take responsibility for uptime, performance, and delivery quality.

Nice to Have

• Experience designing multi-region, high-availability architectures.
• Blue-Green / Canary deployment strategies.
• AWS Certifications (Solutions Architect, DevOps Engineer).
• Experience with performance tuning of databases and message queues.
• Experience building platform standards in fast-growing product companies.

Technology Stack

• Infrastructure: DigitalOcean/Hetzner Linux servers.
• Cloud: AWS (EKS, EC2, S3).
• Containers & Orchestration: Docker, Kubernetes.
• Monitoring: Prometheus, Grafana, Loki.
• Databases: MariaDB/MySQL.
• IaC / CI/CD: Terraform, Helm, ArgoCD, GitlabCI.
• Language: The product is written in PHP.
• Additional Systems: RabbitMQ, Valkey/Redis.

What Success Looks Like

• Production stability and incident rate visibly improved.
• Fully automated, reproducible infrastructure and deployments.
• Clear DevOps standards, documentation, and runbooks.
• Predictable release process with strong observability and rollback.
• Leadership and engineering trust in the DevOps function as a system owner, not just a support role.
