Job description

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior SRE Engineer based in Spain.

This is a high-impact SRE role focused on building reliable, scalable infrastructure for an international gaming platform.
You’ll help shape DevOps and SRE practices while contributing to technical strategy and a strong engineering culture.
The role combines hands-on infrastructure engineering with observability, automation, cloud architecture, and incident management.
You’ll work closely with development teams to improve reliability, scalability, deployment processes, and CI/CD practices.
As a senior engineer, you’ll also mentor teammates and promote Kubernetes-native approaches across the engineering organization.
The environment values autonomy, proactive problem-solving, continuous improvement, and practical automation over bureaucracy.
It’s an opportunity to take meaningful ownership of reliability engineering while working with modern cloud-native technologies.

Accountabilities

• Build and evolve DevOps and SRE practices, helping establish scalable approaches to reliability, infrastructure management, and operational excellence.

• Contribute to the team’s technical strategy and engineering culture, promoting robust, maintainable, and automation-first practices.

• Develop, maintain, and continuously improve the gaming platform infrastructure, with a strong focus on availability, scalability, and resilience.

• Design, operate, and enhance monitoring and observability systems, including metrics, dashboards, exporters, alerting, and reliability indicators.

• Participate in paid on-call rotations, strengthening incident response processes and helping ensure fast, effective resolution of production issues.

• Automate infrastructure operations and repetitive workflows to improve engineering efficiency and reduce manual intervention.

• Partner closely with development teams to improve system reliability, scalability, CI/CD, and change delivery processes.

• Mentor engineers and share Kubernetes-native practices, helping raise technical standards across the wider engineering community.

• Contribute to architectural decisions and cloud infrastructure evolution, balancing performance, reliability, scalability, and operational simplicity.

• Investigate incidents and technical issues systematically, focusing on root-cause analysis and long-term prevention rather than short-term fixes.

Requirements:

• 3+ years of professional experience in DevOps, SRE, or a closely related infrastructure engineering role.

• Deep hands-on expertise with Kubernetes and container orchestration, including operating and scaling production environments.

• Strong experience with Terraform and Infrastructure as Code, with an emphasis on reproducible and maintainable infrastructure.

• Proven experience designing and supporting high-availability infrastructure and production systems.

• Practical experience working with both SQL databases, particularly PostgreSQL, and NoSQL technologies.

• Strong knowledge of observability stacks, including Prometheus, Grafana, exporters, and alerting systems.

• Confident scripting and automation skills using Python and Bash.

• Solid understanding of CI/CD, GitOps, and platform engineering principles and practices.

• Strong systems thinking, with the ability to identify root causes, anticipate reliability risks, and develop sustainable solutions.

• A proactive approach to improving processes, automation, infrastructure, and overall reliability engineering practices.

• Strong communication and collaboration skills, with experience working closely with software engineering teams.

• Experience with Oracle Cloud is a plus.

• Certified Kubernetes Administrator (CKA) certification is desirable.

• Experience with AWS or GCP is beneficial.

• Ability to read and understand JavaScript/TypeScript or Ruby code is an advantage.

Benefits:

• Fully remote working model, with the option to work from dedicated hubs in Kyiv or Warsaw.

• 20 paid working days off, public holidays, and paid sick leave to support sustainable work-life balance.

• Medical insurance with access to leading healthcare providers.

• Coverage for psychological support through the Pleso platform.

• Monthly Benefit Café allowance that can be used toward hobbies, sports, and personal interests.

• Access to team events, workshops, team-building activities, and company celebrations.

• Individual learning and development budget for courses and professional growth.

• Corporate English-language training, workshops, and access to an online learning library.

• Clear career development and performance review framework, alongside mentoring and training programs.

• High level of autonomy and freedom of action, with a culture designed to minimize unnecessary bureaucracy.

• Opportunity to work on technology solutions built from the ground up and contribute to modern cloud-native engineering practices.

• Collaborative, open, and proactive environment where technical ideas, feedback, and continuous improvement are encouraged.
