Tuknik Government Services, LLC, Koniag Government Services (KGS) is seeking qualified candidates for this role supporting our U.S. Army customer on a large-scale Army contracting systems modernization and automation program. Designs, builds, secures, tests, and monitors the interfaces connecting current and migrated capabilities with DLA PIEE modules and external Army and Federal systems. The engineer preserves existing data standards while decoupling legacy components through versioned APIs and adapters. This is a contingent recruiting profile; the opening, employing subsidiary, compensation, work location, and staffing remain subject to final contract authorization.

Essential Functions, Responsibilities & Duties may include, but are not limited to:

Inventory inbound and outbound interfaces, owners, classifications, endpoints, authentication, schemas, dependencies, approval lead times, monitoring, and recovery requirements.
Develop and maintain interface decision matrices, Interface Control Documents, data mappings, record layouts, and operational procedures.
Design and implement secure REST, SOAP, message, file-transfer, and event-based integrations using approved Appian and conventional-code patterns.
Create API facades and adapters that preserve legacy contracts while capabilities and schemas transition into a new solution.
Support integrations involving GEX, GFEBS, FPDS/SAM, VANTAGE, EDA, Closeout, and other authorized PIEE or Army services.
Implement approved authentication, authorization, certificates, secrets, encryption, validation, error handling, retry, idempotency, and audit logging.
Develop automated contract, schema, transformation, negative-case, exception, performance, and recovery tests.
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.
Five or more years designing and supporting enterprise integrations and APIs.
Experience with REST, SOAP, JSON, XML, schemas, authentication, certificates, message/file transfer, API testing, and production monitoring.
Experience integrating workflow platforms, relational databases, conventional applications, and external systems under controlled change processes.
U.S. citizenship and the active security clearance or eligibility required for the assigned work by the start of performance, with ongoing eligibility thereafter.
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.
Experience supporting interfaces across IL-5 and IL-6 boundaries without assuming cross-domain data movement.

Required Skills and Competencies:

API and enterprise integration engineering
Interface security and identity
Schemas, transformations, and data standards
Monitoring, fault isolation, and recovery
ICDs, partner coordination, and controlled cutover

Work Environment and Travel:

Work may occur remotely when authorized, at Government facilities, or in controlled office and data-center environments. Work involving classified information or SIPRNet will be performed at a Government-approved secure location using authorized systems. The role generally supports Government business hours, with occasional release, incident-response, maintenance-window, or approved travel requirements. Reasonable accommodations may be made to enable qualified individuals with disabilities to perform the essential functions.
