Overview

AMERICAN SYSTEMS is seeking our next Software Developer III!!!!

As a Software Developer III on the NISSC 3 program, you will serve as a senior technical contributor and leader across multiple focus areas: DevSecOps Support, PJM Scrum Master, and CMD Manager. You will design, develop, test, and maintain software components that support both cadence-managed and event-driven mission deliverables in a secure, mission-critical environment. You will lead or perform software integration, troubleshooting, and secure coding activities; collaborate closely with systems engineering and test teams; and ensure releases and processes comply with program and DoD standards. In the Scrum Master and CMD Manager variants, you will additionally provide leadership for agile teams and/or command-and-control–related development and coordination. These roles work in close coordination with the EDLM/UDLM (Emergency/Urgent Depot Level Maintenance) Manager.

Responsibilities

For all Software Developer III roles (core responsibilities):

• Design, develop, modify, test, and maintain software components for cadence-managed and event-managed program deliverables.
• Lead or perform software integration, troubleshooting, defect resolution, and performance tuning.
• Apply secure coding practices consistent with DevSecOps and DoD/NIST cybersecurity requirements.
• Use version control and configuration management tools to manage source code, branches, baselines, and releases.
• Collaborate with systems engineering and test teams to implement new features, address findings, and validate changes.
• Document software releases, including change descriptions, test results, known issues, and deployment notes.
• Provide technical input for incident reports, maintenance records, and user/operational documentation.
• Support continuous improvement of development processes, automation, and DevSecOps pipelines.
• Coordinate closely with the EDLM/UDLM Manager to ensure software changes supporting urgent/emergency depot-level maintenance are properly integrated and documented.

Additional focus-area responsibilities may include:

• DevSecOps Support (5 roles): Lead DevSecOps pipeline design and improvements (build, test, security scanning, deployment). Integrate security tools and checks into CI/CD workflows. Mentor junior developers on secure coding and DevSecOps best practices.
• PJM Scrum Master (2 roles): Serve as Scrum Master for one or more development teams, facilitating sprint planning, daily stand-ups, reviews, and retrospectives. Remove impediments, coordinate with Product Owners/Project Managers, and ensure alignment to program priorities. Track and report team delivery metrics (velocity, burndown, etc.) and drive continuous improvement.
• CMD Manager (1 role): Coordinate software activities supporting CMD-related functions (e.g., command-and-control or mission data management). Align CMD-related development schedules and resources with program milestones and stakeholder needs. Support CMD-focused risk/issue tracking and status reporting.

Qualifications

7–10 years of experience in software development, with increasing responsibility and leadership, preferably in secure or mission-critical DoD/defense environments.

Strong experience in software design, development, modification, testing, and maintenance using modern languages and frameworks.
