About the Role

We are seeking a Senior Database Developer / Database Engineer to support the development and modernization of an enterprise-scale federal data platform.

This is a hands-on database engineering role focused on PostgreSQL, Amazon Aurora PostgreSQL, AWS S3, database design, performance optimization, data modeling, and cloud-based data platforms. The ideal candidate will have strong database development and engineering experience rather than a traditional DBA/operations-only background.

You will work closely with application, cloud, data engineering, and architecture teams to design scalable database solutions, optimize performance, support data migrations, and build reliable cloud-native data platforms.

Key Responsibilities

Design, develop, and maintain scalable database solutions using PostgreSQL and Amazon Aurora PostgreSQL.
Develop and maintain logical and physical database models, schemas, tables, indexes, constraints, and storage structures.
Perform database performance analysis, including query optimization, execution-plan analysis, indexing, partitioning, and workload tuning.
Develop and maintain SQL, PL/pgSQL, stored procedures, functions, and database objects.
Design and implement database schema changes and migration strategies across development, test, and production environments.
Work with AWS S3 for data storage, ingestion, loading, and integration with database/data-platform workflows.
Support cloud-native data architectures using AWS services such as Aurora, S3, DynamoDB, Glue, and related data services.
Develop efficient data-loading and migration patterns for large datasets.
Troubleshoot database performance, scalability, availability, and application/database integration issues.
Analyze and improve database structures for high-volume transactional and analytical workloads.
Collaborate with Data Engineers, Cloud Engineers, Software Developers, Solution Architects, and other technical stakeholders.
Implement database security and access-control practices in accordance with federal requirements.
Support schema evolution, database modernization, and migration from legacy platforms to AWS.
Contribute to technical documentation, architecture decisions, and development standards.

Required Qualifications

7+ years of professional database development/engineering experience.
Strong hands-on experience with PostgreSQL.
Hands-on production experience with Amazon Aurora PostgreSQL.
Strong experience with AWS, particularly Amazon S3.
Experience with logical and physical database design and data modeling.
Strong SQL development and database performance-tuning experience.
Experience with indexing, partitioning, query optimization, and execution-plan analysis.
Experience developing stored procedures, functions, and PL/pgSQL.
Experience with database schema migrations and modernization.
Experience working with cloud-based database platforms and data pipelines.
Bachelor's degree in Computer Science, Information Technology, Engineering, or a related field.
Ability to obtain a Public Trust.
