Job Description
This is not a maintenance role. This is a reinvention role located in Huntsville, AL.
We are looking for a Principal Software Engineer who doesn’t just build systems—but reshapes how they are conceived, delivered, and trusted. Someone who pairs deep technical credibility with architectural vision, and who has the conviction to challenge legacy approaches when the mission demands more.
In this role, you will be a technical provocateur and lead engineer, driving the design and delivery of AI-enabled, agentic, and intelligent software platforms that dramatically accelerate modernization and outcomes. You’ll operate at the highest altitude—setting technical direction, evaluating emerging technologies, and prototyping what’s next—while still diving deep to turn ideas into production-grade reality.
This is a role for builders who bias toward action, who believe disruption can coexist with rigor, and who want to apply cutting-edge AI to the problems that matter most.
Why This Role Matters
We are here to radically remake software systems that underpin the country’s most critical missions—aviation, healthcare, energy, and other safety-critical domains where failure is not an option. We are bringing agentic AI transformation not to trivial demos or disposable apps, but to the hardest, highest-stakes systems:
Systems with extreme safety, security, and resilience requirements
Systems constrained by regulation, legacy architecture, and operational risk
Systems where speed to outcome must increase without compromising trust
Our ambition is simple and audacious: move faster than ever before, while raising the bar on safety and reliability.
Key Responsibilities
Technical Leadership & Architecture
Provide Thought leadership in the future opportunities in AI and agentic-enabled tools, capabilities, and challenges
Serve as the architectural lead for AI- and agentic-enabled tooling, establishing patterns, reference implementations, and best practices.
Design scalable, secure, and resilient software systems that integrate LLMs, multi-agent workflows, code intelligence, and automation.
Own and drive the technical roadmap for next-generation software acceleration tools—including IDE extensions, code-analysis agents, refactoring engines, and developer-assistive AI.
Lead architecture reviews, evaluate new technologies, and set engineering standards for AI safety, quality, reliability, and observability.
Hands-On Engineering
Build high-quality software with modern languages and frameworks (e.g., Python, TypeScript, Go, Java).
Develop pipelines and services that enable AI reasoning, code analysis, static/dynamic analysis, and automated transformation of legacy systems.
Prototype early concepts rapidly and transition successful prototypes into robust, production systems.
Integrate AI/ML models (commercial, open-source, or custom) into enterprise environments and developer workflows.
AI & Agentic Systems Development
Design and build agentic orchestration, tool-use interfaces, embeddings systems, context windows, and retrieval-augmented workflows.
Implement “human-in-the-loop” safety and review patterns.
Develop mechanisms for grounding, guardrailing, and evaluating AI performance and correctness.
Leverage AI to analyze, modernize, and refactor large, complex codebases (e.g., Java, .NET, COBOL, C).
Collaboration & Influence
Partner with product, UX, and platform teams to define features, user journeys, and developer experience goals.
Act as a technical mentor to senior and mid-level engineers; cultivate a culture of excellence and continuous learning.
Collaborate closely with research, data, and cybersecurity teams to ensure solutions are safe, secure, and aligned with mission needs.
Represent the engineering team in internal and external forums, contributing to thought leadership in AI and software engineering modernization.
Required Qualifications
Bachelor's degree and 8 years experience in software engineering, including significant experience ... (truncated, view full listing at source)
