At least 11 years of relevant professional experience in software engineering, application and systems integration, API development, DevSecOps, cloud-native engineering, or mission systems development.
Demonstrated experience building, configuring, or integrating APIs, services, adapters, applications, message-based and streaming interfaces, secure file transfer workflows, or containerized workloads.
Proficiency with software development lifecycle and delivery practices, including CI/CD pipelines, automated testing, configuration and version control, change management, security scanning, and release processes.
Ability to produce and maintain technical documentation, such as application architecture diagrams, API specifications, schemas, message definitions, deployment manifests, dependency profiles, test results, release notes, and operational runbook content.
Working knowledge of cloud and hybrid hosting environments, identity integration, attribute-based access control concepts, encryption, PKI, certificates, secrets management, logging, monitoring, and audit requirements.
Strong cross-functional communication and coordination skills, with the ability to work effectively across software, data, cloud, platform, network, cybersecurity, compliance, operations, mission, and Government teams.
Background supporting secure or mission-critical systems, including requirements traceability, authorization documentation, operational readiness activities, and production support.

Responsibilities

Engineer secure integration solutions by designing, developing, configuring, testing, and supporting software components, APIs, services, deployment packages, automation, and mission application interfaces.
Accelerate mission application onboarding by partnering with software development IPTs, platform and compute teams, cloud architects, data teams, cybersecurity, network, enterprise services, operations, and Government stakeholders.
Create repeatable integration patterns that support DevSecOps alignment, application profiling, interface control, test evidence, monitoring integration, production handoff, and operational readiness.
Translate application requirements into integration plans by documenting architecture, dependencies, runtime and compute needs, storage, networking, identity requirements, API specifications, and deployment approaches.
Develop and maintain technical artifacts, including interface control documents, API specifications, schemas, message definitions, service dependency profiles, deployment manifests, test results, release notes, and operational runbook inputs.
Build and support modern integration solutions using APIs, message brokers, streaming services, secure file transfer, containerized workloads, service endpoints, configuration management, and secrets management.
Coordinate with cross-functional technical teams to ensure integrations meet approved architecture, access, encryption, logging, monitoring, authorization, and compliance requirements.
Apply DevSecOps practices throughout the software lifecycle, including backlog refinement, sprint planning, code reviews, CI/CD pipelines, automated testing, security scanning, release management, and change control.
Support identity and access integration by incorporating attribute-based access control, policy enforcement points, service accounts, certificates, keys, secrets, and entitlement requirements.
Evaluate integration performance and readiness through testing focused on functionality, data movement, error handling, resilience, failover, logging, auditability, monitoring, and operational support.
Resolve complex technical issues involving software defects, dependencies, deployment failures, interface errors, service availability, data flows, and production support incidents.
Strengthen mission reliability and delivery speed by developing reusable software patterns, improving technical documentation, capturing lessons learned, and contributing to continuous improvement initiatives.
