Senior API/Connector Engineer

Job Description

Everforth ECS is seeking a Senior API/Connector Engineer to work in the National Capital Region covering the Pentagon, Falls Church, and Fairfax . Please Note: This position is contingent upon contract award.

The War Data Platform (WDP) is a key initiative within the U.S. Department of War's (DoW) AI-First strategy introduced in early 2026. The WDP focuses on operational warfighting data and aims to accelerate the deployment of artificial intelligence (AI) on the battlefield. The WDP extends to Unclassified, Secret, and Top Secret environments, and supports collaboration between Combatant Commands, Joint Staff directorates, Senior Executive Service leaders, and operational analysts.

This role designs, engineers, and sustains reusable connector patterns that enable secure and reliable integration of AI and machine-learning model-serving capabilities across all WDP classification enclaves, delivering consistent, scalable, and Zero Trust-aligned access pathways for production AI model services across NIPRNet, SIPRNet, and JWICS.

Designs, engineers, and sustains reusable connector patterns that enable secure and reliable integration of artificial intelligence and machine-learning model-serving capabilities across Unclassified, Secret, and Top Secret enclaves within the War Data Platform (WDP) Core Integration enterprise.
Develops authentication workflows, throttling mechanisms, protocol translation modules, and routing rules that external model providers, serving proxies, and deployment pipelines depend on to operationalize production-ready models.
Implements API gateway configurations, cross-domain interface controls, encryption policies, and identity enforcement mechanisms aligned with DoW Zero Trust architectures, NIST security controls, and multi-enclave interoperability constraints.
Maintains connector architectures used to support integrations with platforms such as Amazon Bedrock and other model-delivery systems, validating protocol compatibility, performance behavior, and enterprise security posture across NIPRNet, SIPRNet, and JWICS environments.
Collaborates with serving engineers, pipeline specialists, backend developers, and cybersecurity teams to align connector behavior with scanning pipelines, packaging workflows, test-and-evaluation gates, and deployment processes governing model readiness and mission assurance.
Diagnoses integration bottlenecks, resolves service-level defects, and optimizes connector throughput, latency, and reliability using observability tools, API analytics, and performance tuning frameworks.
Produces connector specifications, operational runbooks, architecture diagrams, and release artifacts supporting enterprise promotion cycles and enclave-specific deployments.
Strengthens War Data Platform (WDP) Core Integration mission value by enabling consistent, secure, and scalable access pathways for production AI and machine-learning model services across all domains.
Performs other duties as assigned.

Required Skills

Current Secret security clearance with the ability to obtain and maintain a Top Secret (TS) security clearance with Sensitive Compartmented Information (SCI).
CompTIA A+ certification.
Minimum 10 years of experience designing, engineering, and maintaining enterprise API and connector architectures within classified or federal multi-enclave environments.
Proven track record of defining enterprise-wide API governance strategies, lifecycle management policies, and data-validation contracts that ensure backward compatibility and interoperability across modernized federal systems.
Demonstrated hands-on experience implementing API gateway configurations, authentication and authorization workflows, protocol translation modules, and throttling mechanisms across multi-domain federal networks.
Proven ability to align connector and integration designs with DoW Zero Trust architecture principles, NIST security controls, and cross-domain interoperability constraints, including experience integrating with external model providers such as Amazon Bedrock via secure APIs.
Strong problem-solving and decision-making capabilities, with a proven ability to weigh the relative costs and benefits of potential actions and identify the most appropriate solution.
Highly developed interpersonal and oral/written communication skills, with the ability to effectively and professionally interact with a diverse set of stakeholders (from peers to end-users to executive management).

Desired Skills

Active Top Secret (TS) security clearance with Sensitive Compartmented Information (SCI) eligibility.
Experience integrating observability and API analytics platforms-such as Prometheus, Grafana, or Elastic Stack-into connector architectures to enable real-time performance monitoring, latency optimization, and anomaly detection across multi-enclave AI/ML serving environments.
Demonstrated experience designing resilient, fail-safe integration strategies for low-bandwidth, disconnected, intermittent, or limited-latency (DIL) tactical environments within secure federal networks.
Prior experience working within Platform One or Cloud One environments, including familiarity with hardened artifact packaging, enclave-parity pipeline standards, and DevSecOps automation thresholds relevant to connector and API integration governance.
Familiarity with semantic service and contract layer design concepts-including versioned contracts and authorized use-case frameworks-supporting human users, automated systems, and AI agent consumers across the WDP enterprise.
Track record of producing high-quality connector specifications, architecture diagrams, and operational runbooks that accelerate enterprise promotion cycles and ensure deployment consistency across all classification enclaves.
