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 Switzerland.

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.
