This role focuses on designing, building, and operating large-scale distributed data platforms supporting petabyte-scale environments across hundreds of clusters. You will own complex technical initiatives end-to-end and play a key role in ensuring our data infrastructure remains reliable, scalable, secure, and highly automated.

Design, build, and operate highly available, scalable clusters supporting core data technologies including MongoDB, ElasticSearch, and Apache Kafka.

Own major platform components and deliver complex initiatives from design through to production.

Implement and enhance architectural patterns and platform standards for reliability, scalability, and performance.

Troubleshoot and resolve complex distributed systems issues across multi-cluster environments.

Build and maintain Infrastructure as Code and CI/CD pipelines to ensure repeatable, scalable deployments.

Contribute to observability, reliability, and operational excellence across the data platform estate.

Collaborate with engineering teams and Product Management to align platform capabilities with product needs.

Mentor junior engineers and contribute to knowledge sharing within the team.

Participate in on-call rotations to support platform reliability and continuous improvement.

We’re looking for an experienced Platform Engineer with strong expertise in cloud-native and DevOps practices. The ideal candidate will have:

5+ years of experience in platform engineering, SRE, or infrastructure-focused roles.
