DevOps Engineer

Overview

We are looking for a DevOps Engineer who is fluent in English to join our growing team. In this role, you will be responsible for the deployment, operation, and continuous improvement of our systems across both cloud and on-premises environments. If you are passionate about Linux systems, container orchestration, and automation- and thrive in hybrid infrastructure settings- this opportunity is for you.

Who are we

SESTEK is a global technology company developing AI-powered conversational solutions that empower organizations to be data-driven, enhance efficiency, and offer superior customer experiences. We are an R&D center, and our solutions are developed by a team of over 100 engineers specializing in text-to-speech, speech recognition, natural language processing, and voice biometrics technologies.

As of 2022, we are part of Unifonic, a leading Communications Platform as a Service (CPaaS) provider, and we have grown into an international organization with over 500 dynamic team members.

We have a customer base of 500 enterprises across 20 countries in the US, EU, and MENA regions.

What we expect

• Collaborate with Software Development teams, Product Managers, and Business Owners to ensure smooth deployment and reliable operation of systems in both cloud and on-premises environments.
• Design, develop, and maintain Infrastructure as Code (IaC) to automate provisioning and configuration.
• Administer and support Kubernetes clusters, whether deployed in the cloud or on-premises.
• Build and maintain internal tools and pipelines for deployment, monitoring, and operations.
• Ensure high availability, performance, and security of live systems across different environments.

Who we are looking for

• Fluency in English (written and spoken)
• At least 2 years of experience working in Linux-based environments.
• Solid understanding of networking fundamentals, including routing, load balancing, TCP/IP, HTTP, and DNS.
• Proven troubleshooting and incident response skills.
• Hands-on experience with container technologies (e.g., Docker, containerd) and orchestration tools like Kubernetes and Helm.
• Experience deploying and managing CI/CD tools such as Git, Jenkins, Nexus, and Vault.
• Familiarity with Infrastructure as Code (e.g., Ansible).
• Experience with monitoring tools, especially Prometheus and Grafana.
• Exposure to centralized logging platforms like the ELK Stack (Elasticsearch, Logstash, Kibana).

We're also looking for

• A strong can-do attitude and a hands-on, solution-oriented approach: you see what needs to be done and take action.
• A strong sense of ownership and accountability: you take responsibility, follow through, and don't wait to be told what to do.
• A flexible and collaborative mindset: you enjoy working across teams and are willing to contribute beyond your core responsibilities when needed.
• A willingness to roll up your sleeves, step in where needed, and help the team get things done, even when it falls outside your usual scope.

Nice to have

• Arabic language skills (not mandatory but would be a strong advantage).
• Experience with AWS or other major cloud providers.
• Experience with shell scripting.
• Experience with Terraform for cloud infrastructure provisioning.

What we can offer you

• A chance to be part of a company specializing in artificial intelligence, where you'll work on real products with real impact.
• Flat organizational structure and an energetic team that moves fast and values your voice, so you own outcomes, not just tasks.
• Freedom to try new ideas and build your own solutions, in a culture where failing fast is fine as long as we learn from it.
• Flexible/hybrid working style with the option to work from our İstanbul or Ankara office.
• Private health insurance, meal card, and transportation allowance.
• Incentive for graduate and postgraduate studies.
• Training opportunities for technical and personal development, and support for certificate programs related to the field, in a culture that encourages you to stay curious and keep learning.
• Budget for external activities with your colleagues, organized by the SESTEK Social Activity Committee.
• Birthday celebrations, parties, happy hours, and seasonal events.
• Breakfast and healthy snacks available all day long in the office.
• Exclusive discounts at our partner institutions.
