## Description

You are a thoughtful, collaborative technology professional who turns complex challenges into practical, secure, and maintainable solutions. You work comfortably with engineers, product stakeholders, and federal partners; communicate clearly; and balance delivery speed with quality, traceability, and responsible use of AI. You are energized by mission-driven work and eager to contribute within an established team that values sound judgment and continuous improvement., Aretec is seeking a hands-on Principal Engineer / Technical Lead to guide the architecture and implementation of Greenfield AI Solution within the existing Enterprise Search team. This is not an architect-only position: the successful candidate will make critical design decisions, write production code, lead integrations, review code, and manage technical risk across the application and AI stack., * Own the overall technical architecture for AI Solution, including application, integration, data, and AI design decisions.

 * Provide hands-on technical leadership while designing, implementing, testing, and reviewing production code.
 * Lead complex integrations with Client, enterprise data platforms, authentication services, and supporting APIs.
 * Define scalable patterns for LLM integration, retrieval, agent orchestration, source traceability, evaluation, and guardrails.
 * Translate program objectives into an executable engineering roadmap, sequencing work according to value, complexity, cost, access, and risk.
 * Set engineering standards for security, reliability, maintainability, observability, documentation, and automated testing.
 * Identify architectural and delivery risks early; recommend mitigations and communicate tradeoffs to technical and program stakeholders.
 * Mentor engineers, facilitate design reviews, and resolve cross-stack technical issues without becoming detached from implementation.
 * Partner with federal stakeholders and the Client team to ensure outputs remain grounded in source material and support, not replace, human judgment., * Learn Aretec's mission, the AI Solution objectives, and the Client team's architecture, standards, security boundary, and delivery practices.
 * Build relationships with engineering, program, product, and federal stakeholders.

Day Thirty

 * Validate the target architecture and highest-priority technical risks.
 * Contribute production code and establish practical review, integration, and testing patterns.

Day Sixty

 * Lead major implementation and integration decisions across AI, backend, frontend, and data workstreams.
 * Operationalize evaluation, traceability, and guardrail strategies with measurable quality checks.

Day Ninety

 * Own the technical execution path for key AI Solution capabilities and drive them from design through validated delivery.
 * Mentor the engineering team and establish a sustainable approach to architecture decisions, technical debt, and continuous improvement.
