Job description
The Backend/API Engineer is responsible for designing, building, and sustaining the backend services and API infrastructure that enable secure, scalable access to AI and machine learning models across WDP Core Integration's mission environments. This role sits at the intersection of software engineering, AI/ML operationalization, and DevSecOps delivery, ensuring that production model endpoints, service meshes, and deployment automation pipelines meet the performance, security, and mission assurance standards required across WDP's enterprise application ecosystem.
- Designs, builds, and maintains backend services and application programming interfaces that operationalize artificial intelligence and machine learning model access across War Data Platform (WDP) Core Integration mission environments.
- Implements automated workflows for configuring API endpoints, proxy layers, routing patterns, and service registration logic that provide consistent and secure access to production model artifacts within Unclassified networks.
- Develops scalable serving frameworks using Kubernetes services, API gateways, service meshes, containerized runtime environments, and model-hosting orchestration patterns to support five to ten new endpoints or services per Program Increment while sustaining ten to thirty active production models.
- Implements automated configuration pipelines that bind model artifacts to endpoint specifications, integrate with cross-domain promotion workflows, and align deployment logic with WDP Core Integration's security architecture, enclave requirements, and model evaluation gates.
- Develops reusable backend components, authentication modules, logging interfaces, and monitoring instrumentation using tools such as Flask, FastAPI, NGINX, Envoy, Prometheus, and distributed tracing platforms to strengthen operational visibility and reliability.
- Coordinates with model-serving engineering, cyber engineering, and platform operations teams to establish routing rules, proxy behaviors, and security controls supporting mission assurance standards across the DoW.
- Conducts performance tuning, scalability analysis, and defect remediation to maintain consistent responsiveness and fault tolerance across enterprise workloads.
- Produces service specifications, interface definitions, architecture diagrams, runbooks, and operational metrics that advance WDP Core Integration program value by increasing model accessibility, deployment velocity, and integration consistency across enterprise applications.
- Performs other duties as assigned.
Requirements
Do you have experience in XML?, * Current Secret security clearance.
- A minimum of 3 years of experience in backend software engineering, API development, or a closely related discipline within a federal, defense, or enterprise technology environment, with demonstrated proficiency designing and operating scalable, production-grade backend services and API infrastructure in support of AI/ML model deployment or data platform programs.
- Active IAT Level II certification, satisfied by one of the following: CompTIA Security+ CE, CompTIA CySA+, CompTIA Cloud+, Cisco CCNA Security, GIAC GSEC, GIAC GCED, or ISC² SSCP.
- Demonstrated hands-on experience building and consuming diverse API architectures, including REST and SOAP (via WSDL/XML); deep understanding of API lifecycle management, payload optimization, data serialization formats (JSON, XML), and interface contract definition.
- 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).
