While working with us you’ll get to work on complex distributed systems and solve massive scale problems centered on new payment flows, business and data solutions, cyber security, and B2C platforms.

The Opportunity:

The successful candidate will possess strong troubleshooting and debugging skills. Other responsibilities include effective root cause analysis of major production incidents and the development of learning documentation. The person will identify and implement high-availability solutions for services with a single point of failure.

This includes automating repetitive tasks to reduce manual effort and prevent human errors. The successful candidate will tune alerting and set up observability to proactively identify issues and performance problems. They will also work closely with Level-3 teams in reviewing new use cases and cluster hardening techniques to build robust and reliable platforms. The role involves creating standard operating procedure documents and guidelines on effectively managing and utilizing the platforms. The person will leverage DevOps tools, disciplines (Incident, problem, and change management), and standards in day-to-day operations. The individual will ensure that the Hadoop platform can effectively meet performance and service level agreement requirements. They will also perform security remediation, automation, and self-healing as per the requirement. The individual will concentrate on developing automations and reports to minimize manual effort. This can be achieved through various automation tools such as Shell scripting, Ansible, or Python scripting, or by using any other programming language.

Learner : Constant drive to learn new technologies such as cloud technologies, Kubernetes, MLOPS. Partnership : Experience collaborating with Engineering, Application and Other functional teams.
