Role

In this role you will design systems to enable deployment and management of critical high-volume, low-latency financial systems into public and private cloud environments.

Collaborate cross-functionally with R&D teams to design scalable systems, troubleshoot complex issues, and support new product initiatives.
Champion Infrastructure as Code principles using tools like Terraform and CloudFormation.
Drive observability and reliability through monitoring, logging, and alerting systems (Prometheus, Grafana, Druid, Splunk etc.).
Foster innovation and continuous improvement, adopting new tools and practices to increase efficiency, scalability, and cost optimization.
Contribute to hands-on coding and automation efforts when needed — lead by example.
Partner with stakeholders to align DevOps initiatives with business objectives, including uptime, deployment velocity, and cost efficiency.

Strong understanding of CI/CD pipelines (GitHub Actions, Jenkins, XLR etc.).
Proficient in scripting and programming (Bash, Python, Java).
Experience with monitoring and observability platforms (Prometheus, Grafana, Druid, Splunk, Loki).
Excellent communication skills and the ability to work effectively with Developers, QE, Operations and support teams.
Experience with FinOps or cost optimization in cloud environments
Demonstrated ownership mindset, prioritization skills, and ability to thrive in a fast-paced, multi-tasking environment.
