Overview

AMERICAN SYSTEMS, a 100% employee-owned federal contractor, is seeking a Software Engineer to support the Mission Engineering and Integration Team in Arlington, VA. You will design, develop, integrate, test, and support software components and interfaces that enable secure integration of mission applications and data products across approved platforms.

Responsibilities

As a Software Engineer at AMERICAN SYSTEMS, you will:

Design, develop, and integrate software components, APIs, services, adapters, deployment artifacts, automation scripts, and application interfaces supporting mission integration.
Support application onboarding by documenting architecture, dependencies, runtime, compute, storage, network, identity, API specifications, and deployment approaches.
Develop technical documentation, including interface control documents, API specifications, schemas, message definitions, deployment manifests, test results, release notes, and runbook inputs.
Coordinate with data, cloud, platform, enterprise services, network, security, compliance, and operations teams to meet architecture, access, encryption, logging, monitoring, and authorization requirements.
Implement integration patterns using APIs, message brokers, streaming services, secure file transfer, containers, service endpoints, configuration management, and secrets management.
Apply DevSecOps practices, including backlog refinement, sprint planning, code reviews, CI/CD pipelines, automated testing, security scanning, release management, and change control.
Support attribute-based access control (ABAC) and identity integration through policy enforcement, service accounts, certificates, keys, secrets, and entitlements.
Test software integrations for functionality, data movement, error handling, performance, resilience, logging, auditability, failover, and operational readiness.
Troubleshoot production issues, including defects, dependency gaps, deployment failures, interface errors, service availability issues, and data-flow interruptions.
Improve reusable integration patterns, documentation, lessons learned, and automation to reduce onboarding time and improve mission reliability.

Qualifications

Active Top Secret clearance with SCI eligibility and ability to obtain and maintain SAP access.
Bachelor’s degree in computer science, software engineering, information technology, engineering, or a related discipline.
5 to 7 years of related experience in software engineering, software development, application integration, or a related technical field.
DoD 8140 IAT II level certification such as CompTIA Security+ or an equivalent security certification.
One relevant software development or cloud certification, such as AWS Certified Developer - Associate, Microsoft Azure Developer Associate, or equivalent.
Experience developing or integrating APIs, services, adapters, applications, message-based interfaces, streaming interfaces, secure file-transfer workflows, or containerized workloads.
Working knowledge of the software development lifecycle, CI/CD pipelines, automated testing, configuration management, change control, version control, security scanning, and release management.
Experience documenting application architecture, API specifications, schemas, message definitions, deployment manifests, dependencies, test results, release notes, and runbook inputs.
Familiarity with cloud or hybrid hosting, identity integration, ABAC concepts, encryption, PKI, certificates, secrets management, logging, monitoring, and audit requirements.
Experience supporting secure or mission-critical environments, including requirements traceability, authorization evidence, operational readiness, and production support.
Experience with modern software development using Java, Python, JavaScript/TypeScript, or C#; Git-based source control; automated testing; REST APIs; SQL; and Agile delivery tools.
Ability to work independently and collaboratively with technical, mission, and Government stakeholders.
