Employee Type: Regular

Percentage of Travel Required: None

Type of Travel: None

The Opportunity:

Join our team as a Senior Software Engineer supporting Department of War (DoW) PPBE (Planning, Programming, Budgeting, and Execution) applications. You'll help build and sustain mission-critical defense financial and planning systems that modernize how the DoW plans, programs, budgets, and executes operations. End-to-end software architecture is yours to own, from traditional full-stack development to integrating agentic AI capabilities such as LLM-enabled features and intelligent document processing, and more. Strong engineering fundamentals and federal-sector experience are essential, because this position helps balance a growing team by setting the standard for design, testing, code review, and ownership. Work is performed in both unclassified and classified environments.

Responsibilities:

Design, build, and maintain full-stack applications using modern technologies such as React, TypeScript, NodeJS, Python, and .NET
Lead by example in sound software design, automated testing, code review, and ownership of delivered work
Mentor and support junior developers through code reviews, pairing, and technical guidance
Integrate AI-enabled features into production systems, including LLM/GenAI APIs (OpenAI, Anthropic, Bedrock), RAG pipelines, and agentic workflows, alongside the team's established patterns
Architect reliable API integrations with strong error handling and graceful degradation
Troubleshoot and resolve system defects
Address security vulnerabilities and ensure compliance with DoW cybersecurity standards
Participate in CI/CD pipelines (GitLab) and collaborative development workflows
Document technical implementations and stay current with relevant technology developments

Qualifications:

Required:

Active Secret or Top Secret clearance
Security+ certification
Bachelor's degree in Computer Science, Data Science, Mathematics, or a related STEM field
10+ years of professional software development experience across the full SDLC
Direct, recent experience delivering software in the federal sector (DoD/DoW or other federal agencies), with an understanding of the constraints of federal environments
Direct experience with our technology stack: Python and JavaScript/TypeScript, plus React, NodeJS, and/or .NET
Demonstrated engineering discipline: sound design, testing, code review, and ownership
Experience with RESTful APIs and system integration
Proficiency with Git version control and CI/CD pipelines
Experience with containerization (Docker, Kubernetes) and at least one major cloud platform (AWS, Azure, or GCP)
Strong written and verbal communication skills

Desired:

Interest in or exposure to AI-enabled software engineering, including
LLM APIs, prompt engineering, RAG architectures, agentic patterns, vector databases (Chroma, Weaviate, pgvector), orchestration frameworks (LangGraph, Agno, CrewAI), LLM observability (Phoenix, LangFuse, LangSmith)
Knowledge of DoD PPBE processes, defense budget formulation (POM, BES, J-Books, FYDP), or DoD financial systems (e.g., NGRMS, GFEBS, DAI, DEAMS)
Experience with AWS GovCloud, AWS Bedrock, or Azure OpenAI Service
Working knowledge of Kubernetes, Terraform or other IaC tools
Familiarity with ATO processes, NIST frameworks, or FedRAMP
Familiarity with Agile methodologies (Jira)
