Overview

The EOSDIS Evolution and Development (EED) program supports NASA's Earth Science Data and Information System (ESDIS) in enabling global, open access to critical Earth observation data. As part of its growing EED support team, STC is seeking a Senior Core System Operator/Developer to support the Consolidated Cumulus Core team.

The Senior Core System Operator/Developer is a senior technical implementer responsible for the foundational monitoring, operations, and infrastructure development of the Consolidated Cumulus system. This role combines active software development with hands-on operational responsibility — building scalable infrastructure, handling support requests, monitoring and improving system performance, and maintaining system health through CI/CD pipelines and proactive incident response. This role reports to the Consolidated Cumulus Core Product Owner.

Primary Responsibilities

• Design, develop, and continuously improve foundational Cumulus software to ensure scalable operations and throughput optimization.
• Develop and optimize Cumulus Core software, including internal libraries and APIs.
• Integrate advanced data backup and preservation technologies into the infrastructure, utilizing AWS S3 versioning, locking, and cross-region/cross-cloud strategies.
• Produce and manage comprehensive software documentation for all developed features.
• Integrate technical requirements and inputs from the Systems Architect, Systems Engineer, and Cloud-Infrastructure Engineer.
• Ensure all architectural and infrastructure designs maintain strict adherence to documented SLAs.
• Execute CI/CD, system testing, and performance testing for all Cumulus Core software updates.
• Maintain standards-driven CI/CD pipelines and provide automated testing support across the broader development effort.
• Maintain comprehensive software documentation and automated unit/integration tests for all new platform features.
• Perform system sustainment tasks, including security updates and Cumulus system health monitoring.
• Address bugs or issues in accordance with the SLA.
• Perform deep-dive root cause analysis (RCA) to prevent recurring technical failures.
• Proactively communicate system status and resolution progress to the Product Owner, Operations Manager, and Data Operations Team Leads.

In addition to the Core Developer duties above, the Senior Core System Operator/Developer is specifically responsible for:

• Monitoring system health, performance metrics, and operational status of the Cumulus Core environment.
• Handling operational support requests and driving timely resolution in accordance with SLA commitments.
• Developing and maintaining operational runbooks, monitoring dashboards, and automated alerting capabilities.

Job Requirements

• 6+ years' software engineering experience, including Agile development (preferably Scrum or SAFe), using the Atlassian tool suite (JIRA, Confluence, Bamboo), and developing on MacOS X and deploying to Red Hat Enterprise Linux
• Expert-level experience with AWS infrastructure, specifically S3 data management (versioning, locking, cross-region architectures), Lambda, Step Functions, and RDS
• Proven track record in developing and optimizing core libraries, APIs, and complex software systems
• Demonstrated commitment to automated testing, CI/CD integration, and rigorous documentation standards
• Proficiency in root cause analysis for high-level system errors and infrastructure bottlenecks
• Degree in Computer Science, Engineering, or a related technical field

Desired Skills and Experience

• Python and React
• Experience developing with AI/ML tools or frameworks
