Instrument interfaces with correlation identifiers, health checks, structured logs, alerts, and dashboards for rapid fault isolation.
Coordinate network, identity, DNS, certificate, firewall, boundary, and partner-system changes before cutover.
Support interface migration, parallel operation, conformance, security, regression, operational acceptance, rollback, and retirement.

Education and Experience Required:

Bachelor's degree in computer science, engineering, information systems, or a related field; additional relevant experience may substitute for education.

Ability to communicate clearly with Government, technical, and business stakeholders and to maintain accurate work records in approved systems.
Ability to protect Controlled Unclassified Information and classified information, when assigned, and comply with required access, training, and handling procedures.

Education and Experience Desired:

Experience with Appian Integration Objects, Connected Systems, web APIs, plug-ins, or integration SDKs.
Experience with PIEE, GEX, GFEBS, SAM.gov, FPDS, VANTAGE, PDS/PRDS, or other acquisition interfaces.
