💡 About the Company

We’re working with a leading software development partner that helps global organizations build and scale cutting-edge digital products.
This company specializes in end-to-end technology consulting — from cloud-native architecture and DevOps automation to high-performance applications and data-driven platforms.

They collaborate with clients from various industries — fintech, healthcare, data analytics, and more — designing solutions that are secure, scalable, and built for growth.

Here, engineering excellence truly matters. You’ll join a team where autonomy, curiosity, and technical mastery are valued, and where you can have a real impact on how complex systems are designed and delivered.

⚙️ The Role

As a Senior Site Reliability Engineer, you’ll play a key role in ensuring smooth and reliable operation of critical infrastructure and applications — both internally and for the company’s clients.

Your work will focus on Jenkins, Kubernetes, AWS, and Terraform, helping to design, maintain, and optimize cloud infrastructure and CI/CD processes.

This is a hands-on position where you’ll collaborate closely with development teams, advise on best practices, and drive automation at every level.

🔧 What You’ll Do

• Design and maintain CI/CD pipelines in Jenkins (Groovy/Jenkinsfiles, master/agent setup, pipeline optimization).

• Manage and troubleshoot Kubernetes environments – deployments, Helm/Kustomize, security, and networking.

• Build and operate AWS infrastructure, using best practices across core and advanced services (certification a plus).

• Implement and manage Infrastructure as Code with Terraform – including complex modules and state management.

• Automate workflows and processes using Python, Go, or Bash.

• Set up and maintain monitoring and alerting with Prometheus, Grafana, or Datadog.

• Investigate and resolve performance, scalability, and reliability issues.

• Collaborate with cross-functional teams to deliver robust, production-ready environments.

• Continuously improve system reliability, deployment speed, and operational visibility.

🧩 What We’re Looking For

• Advanced knowledge of Jenkins (CI/CD, Groovy scripting, agent management).

• Extensive experience with Kubernetes, including Helm/Kustomize, networking, and security.

• Strong understanding of AWS cloud services and best practices.

• Proven skills in Terraform (modular, complex configurations).

• Strong scripting abilities in Python, Go, or Bash.

• Solid experience with Linux and networking fundamentals (TCP/IP, DNS, HTTP/S).

• Hands-on experience with monitoring tools (Prometheus, Grafana, Datadog).

• Great communication skills and a proactive, problem-solving mindset.
