What Is a Database Developer?

A database developer works in an Information Technology (IT) department creating and maintaining databases. You monitor and troubleshoot databases and run debugging processes. Responsibilities can include offering support to other departments or clients, updating systems, advising management on tech solutions and security, and managing machine data. You use computers, cloud data, applications, and programs to improve processes and streamline coding strategies. You may also have duties like presenting information to clients or upper management, and proposing and enacting system updates.

What does a database developer do?

A database developer designs, creates, and maintains databases to store and organize data efficiently. They write SQL queries, optimize database performance, and ensure data security, often working with database management systems like MySQL, Oracle, or SQL Server. Strong problem-solving skills and knowledge of data modeling are essential for this role.

What are some common challenges faced by Database Developers when working on large-scale projects?

Database Developers working on large-scale projects often encounter challenges such as optimizing query performance, ensuring data integrity, and managing database scalability. As databases grow, maintaining efficient indexing, handling concurrent access, and implementing robust backup and recovery strategies become increasingly complex. Collaboration with application developers and system administrators is essential to ensure smooth integration and to address issues related to data migration and security. Staying updated with the latest database technologies and best practices can help mitigate these challenges and contribute to project success.

The contract has a one-year base period with a potential of three option periods.


Tasks:

  1. Database and Applications Development: Bring together scientific and administrative data currently fragmented across various legacy platforms, file formats, and isolated silos as part of a critical enterprise data management initiative. Duties include (but are not limited to) building pipelines to centralize data from plankton and groundfish surveys; designing the database architecture to house the centralized survey data; and developing front-end applications that allow internal staff and external partners to securely manage and validate the data.


  1. Enterprise Data Ingestion and Migration (ETL)
  1. Analyze disparate data sources (flat files, .db3, Access databases, legacy SQL, APIs) and design automated workflows to extract, transform, and load (ETL) data into a centralized Oracle Enterprise environment.
  2. Develop parsing algorithms to handle inconsistent data formats and ensure data integrity during the migration process.
  3. Implement data validation rules to flag anomalies during ingestion.


  1. Database Architecture and Management
  1. Design and maintain normalized relational database schemas that support complex fishery survey and oceanographic data structures.
  2. Optimize database performance through indexing, partitioning, and query tuning.
  3. Ensure strict adherence to federal data security standards and PII protection protocols.


  1. Application Development (Internal and External)
  1. Internal interface: develop a user-friendly web application allowing internal NOAA staff to input, query, and edit live data records.
  2. External partner workflow: create a secure portal for external partners to view and input data and propose edits.
  3. Approval logic: engineer a "staging and commit" workflow where external edits are held in a review queue (edits do not affect the production database until reviewed and approved by the Database Manager or appropriate data steward).


  1. Support for Other Research Activities: Support other Trawl and Plankton Branch, PEMD, and SEFSC surveys, including but not limited to:


  1. Provide support for data analyses and prepare data summaries.
  2. Assist with the development of data reports, publications, and presentations, as needed; adhere to SEFSC publication procedures prior to publication of any abstracts or manuscripts.

  • MS Degree in Computer Science, Information Systems, Engineering, or a related field of study; or BS Degree in one of these disciplines, five (5) years of relevant experience.
  • Ability to translate real-world scientific processes into logical and physical data models (Entity-Relationship Diagrams).
  • Ability to write complex stored procedures, triggers, and packages (PL/SQL) to handle business logic and the "edit-approval" workflow.
  • Knowledge of implementing Role-Based Access Control (RBAC) to differentiate between different use and access requirements..
  • Skill in creating technical documentation, data dictionaries, and user manuals.
  • Software proficiency includes, but is not limited to:
    • Database Engines: Expert-level proficiency in Oracle RDBMS (12c/19c or later). Knowledge of PostgreSQL or SQL Server is a plus.
    • Development Frameworks: Proficiency in Oracle APEX (Application Express) is highly desired for rapid development of data-centric web apps. Alternatively: Java (Spring Boot), Python (Django/Flask), or .NET.
    • ETL & Scripting: Python (Pandas/NumPy), PL/SQL, Informatica, or FME.
    • Front End: HTML5, CSS3, JavaScript, and AJAX techniques for responsive user interfaces.
    • Version Control: Git/GitHub/GitLab.


LEVEL III Desirable:

  • Documented experience working with geospatial data (GIS, Oracle Spatial, ArcGIS).
  • Documented experience in database development and administration
  • Documented experience building workflows with approval gates/audit trails
  • Ability to communicate with fishery scientists to understand their data needs and translate them into technical specifications.
