Senior Data Engineer

Senior Data Platform Engineer — Cloudera, AWS & Kubernetes  The mission  We are looking for a battle-tested Data Platform Engineer who can build, operate, troubleshoot, and evolve large-scale data platforms across on-premises Cloudera environments and cloud-native AWS/Kubernetes architectures.  This is not a dashboard or SQL-only role. You will work where distributed compute, storage, networking, Kubernetes, and production data pipelines meet. You must be comfortable tracing a failed workload from the application layer through Spark or Flink,  Kubernetes operators, HDFS/Hive, infrastructure, and AWS services.  The goal is to help us evolve safely from on-premises, VM, and EC2-based platforms into resilient, observable, cloud-native data systems.  What you'll do  - Build and operate production data platforms across Cloudera on premises, Cloudera cloud environments, AWS EMR, and Kubernetes.  - Design batch and streaming pipelines using Spark, Flink, Hive, and related technologies.  - Transform large datasets through filtering, sorting, joining, aggregation, partitioning, enrichment, and restructuring.  - Work with Parquet, Avro, JSON, CSV, and other delimited or semi-structured formats.  - Design storage, partitioning, compression, retention, and lifecycle strategies across HDFS, Hive, and object storage.  - Design and maintain Hive schemas, tables, partitions, metadata, and data models.  - Administer Cloudera clusters, including installation, upgrades, configuration, scaling, patching, security, backup, and recovery.  - Troubleshoot unhealthy services, failed jobs, resource contention, data skew, small-file problems, metadata issues, and storage bottlenecks.  - Tune Spark and Flink workloads for memory, CPU, parallelism, shuffle behavior, checkpointing, and recovery.  - Operate AWS services such as EMR, S3, IAM, EC2, EKS, CloudWatch, KMS, and supporting networking services.  - Deploy and operate data workloads on Kubernetes using operators, Helm, custom resources, and GitOps-based delivery.  - Help migrate workloads from physical or virtual machines and EC2 into AWS and Kubernetes-based platforms.  - Separate compute from storage where appropriate while accounting for performance, resilience, security, and cost.  - Build monitoring, alerting, capacity management, and operational runbooks for critical data services.  - Automate platform provisioning and configuration using Terraform, Ansible, scripting, and CI/CD.  - Support production incidents involving failed pipelines, delayed data, cluster degradation, storage pressure, or infrastructure failure.  - Work with data engineering, infrastructure, security, and application teams to resolve problems across ownership boundaries.  What we're looking for  - Strong hands-on experience administering Cloudera platforms in production.  - Experience with both on-premises Cloudera and cloud-based Cloudera deployments.  - Deep working knowledge of Hadoop, HDFS, Hive, YARN, Spark, and the wider distributed-data ecosystem.  - Experience building or operating production workloads using Apache Flink.  - Strong understanding of distributed data processing, including partitioning, shuffling, serialization, checkpointing, and failure recovery.  - Experience transforming large datasets using joins, aggregations, filtering, sorting, and schema evolution.  - Practical knowledge of Parquet, Avro, JSON, CSV, compression formats, and serialization tradeoffs.  - Experience designing data layouts for query performance, ingestion throughput, retention, and cost.  - Strong AWS experience, particularly with EMR, S3, EC2, EKS, IAM, CloudWatch, and KMS.  - Strong Kubernetes experience, including operators, controllers, Helm, scheduling, storage, networking, and workload troubleshooting.  - Experience migrating data platforms from on-premises or VM-based environments into AWS and Kubernetes.  - Ability to troubleshoot Linux, JVM, networking, storage, DNS, certificates, and resource-management issues.  - Experience with observability platforms and the ability to correlate infrastructure symptoms with data-pipeline failures.  - Ability to automate operational work using Python, Bash, Terraform, Ansible, or equivalent tools.  - Strong judgment around production changes, data integrity, access control, rollback, and recovery.  Production scenarios you should be able to handle  - A Spark job that ran in 40 minutes yesterday now takes four hours.  - A join creates severe data skew and repeatedly exhausts executor memory.  - HDFS is approaching capacity while NameNode health is degrading.  - Hive queries return incomplete results because partitions or metadata are inconsistent.  - A Flink job repeatedly fails after checkpoint recovery.  - An EMR workload is reliable but significantly more expensive than expected.  - A Kubernetes operator reports success while the underlying data workload is unhealthy.  - A migrated workload behaves differently on S3 than it did on HDFS.  - A certificate, Kerberos, IAM, DNS, or network problem presents as an application failure.  - A critical pipeline misses its SLA and ownership is unclear across platform and data teams.  Certifications  Relevant certifications are useful, particularly:  - Cloudera Certified Professional: Data Engineer  - Cloudera Administrator certification or equivalent production experience  - AWS data, analytics, or architecture certifications  - Kubernetes certifications such as CKA or CKAD    What success looks like  - Data pipelines meet their reliability and processing-time objectives.  - Platform failures are detected before downstream consumers report them.  - Incidents move quickly from symptoms to an evidence-backed root cause.  - Cloudera, AWS, and Kubernetes environments are operated through repeatable automation.  - Migrations preserve data correctness while improving scalability and operability.  - Storage and compute designs balance performance, resilience, and cost.  - Data engineers can ship workloads without becoming accidental platform administrators.  - Operational knowledge becomes monitoring, automation, and runbooks—not tribal memory.  The person we want  You understand that a data platform is a distributed production system, not a collection of product names.  You can move from a Hive execution plan to Spark executor logs, Kubernetes events, HDFS health, S3 behavior, IAM permissions, and network telemetry without losing the thread. You know the architectural differences between on-premises Hadoop and cloud-  native data platforms, including where a lift-and-shift approach will fail.  We need someone who can enter a degraded platform, establish the facts, protect data integrity, restore service, explain the failure chain, and make the system harder to break next time.
