Position Summary

Unison Software is seeking a Senior Integration Consultant to serve as the senior technical authority for system integration across federal programs, connecting Unison's acquisition, grants management, and contract lifecycle solutions with client enterprise systems.

This is a hands-on senior delivery role. Senior Integration Consultants own integration architecture across a program, set and enforce integration standards, serve as the escalation point for the most difficult interface problems, and provide direction, review, and mentorship to other technical consultants while personally delivering the most complex interfaces.

Program assignment, interface portfolio, and team size scale with the engagement and are defined in the specific job posting.

Key Responsibilities

• Own integration architecture across the program, including interface inventory, integration patterns, data contracts, and end-to-end data flow design across interfacing systems
• Establish, document, and enforce technical standards for development, configuration management, deployment, and technical documentation
• Provide technical direction to other technical consultants, including task assignment, design guidance, and review of their work products
• Conduct design and code reviews and hold the quality bar for maintainability, performance, and security across the technical team
• Serve as the technical escalation point for complex interface failures and data exchange issues, leading root cause analysis and durable resolution
• Mentor and develop technical consultants, building depth on the team through knowledge transfer, pairing, and structured feedback
• Design, build, and deliver the most complex integrations personally, including high-volume, real-time, and multi-system interfaces
• Partner with clients, functional consultants, project managers, and third‑party system owners to translate business requirements into scalable integration designs and realistic delivery approaches
• Provide technical input into estimates, level of effort, staffing plans, and proposal and capture activities for new and follow‑on work
• Assess integration risk across the program, including dependencies, environment readiness, security posture, and interface performance, and communicate it to project and program leadership
• Lead integration planning for implementation, upgrade, cutover, and post‑production activities, including interface validation and production support
• Serve as a trusted technical advisor in client‑facing meetings, design sessions, and technical governance forums

Qualifications

Preferred Experience

• Professional experience designing, developing, and supporting system integrations, with depth of experience commensurate with the level of the position
• Prior software development experience is highly preferred
• Experience owning solution architecture and technical design decisions across multiple workstreams
• Experience providing technical direction, design and code review, and mentorship to other technical staff
• Experience building interfaces between enterprise systems such as ERP, financial management, procurement, or personnel systems
• Experience supporting enterprise software or large‑scale system implementations
• Experience in client‑facing technical roles supporting federal government agencies or government contractors

Technical Skills and Exposure

• Strong SQL skills and hands‑on experience with relational databases
• REST and SOAP web services, API design, and API management concepts
• Common integration patterns, including message routing, transformation, orchestration, and error handling
• Integration and ETL platforms such as Talend Data Services or comparable tools
• Java and integration frameworks such as Apache Camel and Apache CXF
• Message queuing, file transfer protocols, and scheduled batch processing
• Interface monitoring, logging, alerting, and error handling design
• Cloud‑based integration architectures and hybrid on‑premises integration
• Integration security concepts, including authentication, authorization, certificate management, and data protection

Federal Delivery and Data Environment

Familiarity with one or more of the following is preferred:

• Federal acquisition, contract, grants, and financial data structures and the systems that produce them
• Interfaces with federal financial, procurement, personnel, and reporting systems
• Handling of sensitive federal data, including personally identifiable information (PII) and controlled unclassified information (CUI)
• Federal security and compliance requirements, including FISMA, authority to operate (ATO), and Section 508 accessibility
• Working with government technical points of contact, information system security officers, and system owners

Core Skills and Abilities

• Strong analytical and problem‑solving skills, including with ambiguous or poorly documented systems and data
• Ability to explain technical decisions, risks, and tradeoffs clearly to non‑technical client stakeholders and program leadership
• Sound technical judgment under delivery pressure, balancing speed against maintainability
• Ability to manage multiple priorities and workstreams in a collaborative, client‑facing environment
• Ability to adapt quickly to new technologies and evolving client requirements

Education and Certifications

• Bachelor’s degree (BA or BS) in Computer Science, Information Systems, Software Engineering, or a related technical field, or equivalent professional experience
