The role focuses on reliable execution, automation, governance, monitoring, and production support for large-scale enterprise data migration.\n________________________________________\nKey Responsibilities\nOwn the end-to-end migration workflow from OBSv2 source buckets to AWS S3 destination buckets.\nBuild and operate AWS-based orchestration using Step Functions, Lambda, Fargate, AWS Batch, DynamoDB, SQS, and rclone.\nSupport both manifest-based and dynamic migration approaches, including batching, sharding, task sizing, and retry handling.\nImplement governance for bandwidth allocation, queue management, prioritization, throttling, and job tracking.\nBuild observability through CloudWatch dashboards, logs, metrics, alerts, health checks, and progress reporting.\nSupport secure multi-account deployment, IAM controls, privacy safeguards, testing, performance tuning, and production cutover.\n________________________________________\nExpected Deliverables\nProduction-ready migration orchestration platform supporting both manifest and no-manifest paths.\nHub-side governance for bandwidth control, queue processing, throttling, and completion reporting.\nReusable rclone-based migration runtime with progress reporting and dynamic throttle support.\nDynamoDB-backed job, task, queue, bandwidth, and summary state management.\nCloudWatch dashboards, alarms, logs, runbooks, deployment automation, and operational documentation.\n________________________________________\nPreferred Experience\nExperience with Dell ECS, OBSv2, or other S3-compatible enterprise object storage platforms.\nExperience delivering enterprise-scale migrations in regulated, production environments.\nExperience with hub-and-spoke operating models across multiple AWS accounts.\nAbility to produce clear technical documentation and leadership-ready reporting.\n________________________________________\nMandatory Technical Skills\nSkill Area Mandatory Skill Requirement\nAWS Serverless Hands-on experience with AWS Lambda, Step Functions, SQS, SNS, EventBridge, API Gateway, SSM Parameter Store, and Secrets Manager.\nAWS Compute and Containers Strong working knowledge of ECS Fargate, AWS Batch, container task definitions, sidecar patterns, resource sizing, and runtime environment configuration.\nAWS Storage Deep understanding of Amazon S3, S3 Intelligent-Tiering, S3-compatible APIs, object metadata, prefix structures, large object transfers, and lifecycle considerations.\nObject Storage Migration Experience migrating large object datasets from on-premises or S3-compatible platforms such as Dell ECS/OBSv2 to AWS S3.\nrclone Hands-on experience configuring and operating rclone for high-volume transfers, including transfers, checkers, retries, checksum validation, no-traverse behavior, stats, logs, and bandwidth limiting.\nPython Development Strong Python skills for Lambda and Fargate services, including boto3, JSON processing, exception handling, logging, dataclasses, streaming files, and API integration.\nDynamoDB Ability to design and operate DynamoDB tables, keys, indexes, scans, updates, batch writes, Decimal handling, and state-management patterns.\nNetworking Understanding of AWS Direct Connect, Transit Gateway, VPCs, private subnets, routing, S3 Gateway Endpoints, NAT Gateway scoping, and high-throughput network design.\nIAM and Security Strong knowledge of IAM roles, cross-account access, STS assume-role, API keys, Secrets Manager, least-privilege design, and secure operational access.\nObservability Experience with CloudWatch metrics, logs, alarms, dashboards, structured logging, operational telemetry, and migration progress reporting.\nCI/CD and Deployment Experience with GitLab repositories, CI/CD pipelines, environment-specific configuration, infrastructure deployment, and safe teardown procedures.\n________________________________________\nKnow-How Skills and Domain Understanding\nUnderstand large-scale object storage migration patterns, including manifests, prefix-based partitioning, batching, and validation.\nBalance migration performance across data volume, object count, compute resources, network capacity, and rclone concurrency.\nDesign fair bandwidth allocation, throttling, queue handling, retry, and escalation models for production migrations.\nApply strong operational discipline across monitoring, runbooks, restart procedures, completion checks, and stakeholder reporting.\nMaintain clear technical documentation, architecture notes, input contracts, implementation details, and support procedures.","description_format":"text","description_chars":4728,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Data
