What is a middleware developer?

Middleware Developers are IT professionals who design, develop, and maintain software that connects different applications, systems, or databases within an organization. They focus on creating middleware, which acts as a bridge to facilitate communication and data exchange between disparate systems. Their work ensures that applications can interact smoothly, improving efficiency, scalability, and integration in complex IT environments. Middleware Developers often work with technologies such as message brokers, APIs, and enterprise service buses.

What are the key skills and qualifications needed to thrive as a middleware developer?

To thrive as a Middleware Developer, you need strong programming skills in languages like Java or Python, a deep understanding of middleware platforms (such as WebLogic, IBM WebSphere, or Apache Kafka), and a relevant degree in computer science or related fields. Familiarity with integration tools, APIs, messaging systems, and often certifications in specific middleware technologies are commonly required. Excellent problem-solving, teamwork, and communication skills help developers collaborate effectively and respond to complex integration challenges. These skills are crucial for building reliable, scalable systems that enable seamless data exchange and application connectivity across an organization.

How does a middleware developer typically collaborate with other teams during a project lifecycle?

Middleware Developers play a crucial role in bridging the gap between front-end and back-end teams. They frequently collaborate with software engineers, database administrators, and system architects to ensure seamless data flow and integration between different applications. Effective communication and problem-solving skills are essential, as Middleware Developers often participate in cross-functional meetings to troubleshoot issues, align on technical specifications, and implement integration solutions that meet business needs. Their work ensures that applications can communicate efficiently, supporting overall system reliability and scalability.

This transformational initiative will deploy Oracle Fusion Cloud HCM as the unified human capital management platform for federal civilian employees across numerous agencies. In this role, you will design, build, and maintain the ETL pipelines and middleware that transform legacy HR data extracted from agency source systems into Oracle Fusion HCM Data Loader (HDL) and HCM Spreadsheet Data Loader (HSDL) formats for loading into the target platform.

You will process agency migrations ranging from small agencies with 10,000 employees to extra-large federal agencies, building scalable data transformation pipelines with robust error handling, data cleansing, and reconciliation capabilities. Your work will directly determine the data quality and migration success for every agency transitioning to the new Oracle Fusion Cloud HCM platform. This position is primarily remote; however, candidates may be required to report onsite in Reston as business needs arise.

Responsibilities: Design and develop ETL pipelines using Oracle Integration Cloud (OIC), Informatica, Talend, or equivalent middleware tools to transform extracted legacy HR data into Oracle Fusion HCM HDL and HSDL load file formats. Build data transformation rules that map legacy data values (codes, descriptions, hierarchies) to Oracle Fusion HCM reference data, value sets, and lookup values for each agency migration. Develop data cleansing pipelines that identify and remediate data quality issues including missing required fields, invalid date formats, duplicate records, and referential integrity violations before target system loading.

Design and implement batch processing frameworks capable of handling large-volume agency migrations ranging from small to very large agency employee populations with configurable parallelism and restart/recovery capabilities. Build comprehensive error handling and exception management within ETL pipelines including error categorization, automated retry logic, and error reporting dashboards for migration teams. Develop data reconciliation processes that compare source record counts, key data element values, and business rule validations between legacy extracts, transformation outputs, and target system loaded records.

Create and maintain data quality dashboards providing real-time visibility into migration pipeline status, error rates, data completeness metrics, and reconciliation results for each agency migration wave. Design reusable transformation templates and parameterized mapping configurations that accelerate successive agency migrations by leveraging patterns from completed migrations. Collaborate with legacy system export developers (PeopleSoft/EBS team) to define extraction file formats, handoff procedures, and data interface specifications.

Support iterative mock migration cycles (typically 3-4 per agency) and final cutover data loads, optimizing pipeline performance and resolving data quality issues identified in each cycle. Document ETL design specifications, transformation rules, data flow diagrams, and operational runbooks for each agency migration in accordance with SAFe Agile artifact standards. Operate with significant independence to analyze and resolve complex functional and technical issues, applying advanced techniques and serving as a go-to technical resource and mentor for less experienced team members across the program.

Lead small work efforts and technical initiatives within the assigned functional area, contributing to team strategy, conducting technical reviews of deliverables, and guiding junior consultants on Oracle Fusion Cloud HCM best practices and solution approaches. Qualifications: Required: Bachelor's degree and 7 years of relevant experience. Additional experience may be substituted for degree.

7+ years of experience in ETL development, middleware development, or data integration for enterprise system implementations. 5+ years of hands-on experience with ETL/middleware tools such as Oracle Integration Cloud (OIC), Informatica PowerCenter/Cloud, Talend, or equivalent data integration platforms. Strong SQL proficiency with experience writing complex transformation queries, data validation scripts, and reconciliation procedures.

Experience with batch data processing for large-volume datasets (100,000+ records) including performance optimization, error handling, and restart/recovery design patterns. Knowledge of data quality management principles including data profiling, cleansing, standardization, and validation. Experience with file-based data integration formats (CSV, XML, JSON) and enterprise data loader specifications.

Familiarity with Agile/SAFe development methodologies and iterative delivery practices. Must be able to obtain and maintain a Public Trust clearance (US Citizenship required). Desired: 8+ years of ETL/middleware development experience with specific experience on HCM or ERP data migration projects.
