About the role

Key responsibilities & impact

Construct infrastructure as code using tools such as Terraform; develop and enforce best practices across configurations while preventing drift between code and deployed infrastructure.
Design and operate infrastructure that enables Engineering, Data Science, and Analytics teams to efficiently perform software development and data processing workloads (including Hadoop-based systems).
Implement monitoring tools, dashboards, and functionalities for a variety of services and operations across SentiLink’s infrastructure and software platform.
Design, implement, and maintain scalable DevOps and CI/CD pipelines to automate application deployment and infrastructure provisioning, supporting reliable production operations.
Participate in Level 2 operational support, root cause analysis, and infrastructure improvements following incidents.
Formulate strategies and execute solutions for cloud identity and access management.
Collaborate with SRE and security teams to maintain secure, up-to-date infrastructure in the cloud environment.
Supervise and monitor platform costs, working cross-functionally to maintain cost awareness (cost optimization experience is a plus, not a core requirement).
Oversee, develop, and operate Kubernetes infrastructure, including deployment workflows using tools such as Argo CD and Kargo.
Investigate operational alerts, identify root causes, and produce comprehensive root cause analysis reports; ensure follow-up actions are completed thoroughly.
Conduct in-depth examinations of database operational issues, contributing to improvements in database architecture, configuration, and reliability.
Support and operate Airflow workflows and related infrastructure.
Write and maintain Python automation scripts, along with Bash and shell scripting, to support infrastructure operations.
