You

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.

What We are Looking For

Aretec is seeking a Senior AI / Backend Engineer to build the intelligent services behind a greenfield AI solution. You will develop Python services, LLM integrations, retrieval pipelines, agent workflows, APIs, guardrails, and automated evaluations that produce useful, well-grounded results with clear references to supporting source material.

Key Responsibilities

• Design and develop Python backend services and APIs for the greenfield AI solution.
• Integrate large language models and build retrieval-augmented generation pipelines over approved enterprise data sources.
• Implement agent orchestration and reusable prompt-framework components.
• Build retrieval, ranking, context-assembly, and citation mechanisms that tie summaries and findings to supporting documents.
• Develop guardrails that constrain unsupported assumptions, overly prescriptive outputs, legal determinations, and decisions that belong to human staff.
• Create deterministic and probabilistic evaluation automation that measures accuracy, completeness, consistency, grounding, and adherence to guardrails.
• Build automated unit, integration, regression, and AI-quality tests.
• Instrument services for troubleshooting, performance analysis, and continuous improvement.
• Work closely with the technical lead, data engineer, full-stack engineer, and enterprise-search stakeholders throughout design and delivery.

The Skills We are Looking For

Required Qualifications

• Strong Python software-development skills.
• Practical experience integrating LLMs into production or production-oriented applications.
• Experience designing RAG systems, retrieval pipelines, embeddings, context construction, or comparable information-retrieval workflows.
• Experience with RESTful APIs and backend service design.
• Understanding of agent orchestration, prompt design, AI guardrails, and model-output evaluation.
• Experience with automated testing and disciplined software-engineering practices.
• Strong analytical, debugging, documentation, and communication skills.

Preferred Skills

• Experience with source citation, document intelligence, enterprise search, or knowledge-retrieval systems.
• Experience with structured human feedback loops and AI evaluation frameworks.
• Experience delivering applications in federal, regulated, or security-conscious environments.
• Familiarity with identity, access control, observability, and secure API integration.

The Expectations of the Job

Day One

• Learn the greenfield AI solution use cases, enterprise-search environment, available data sources, security boundaries, and current AI components.
• Align with the technical lead on development standards and priority workflows.

Day Thirty

• Deliver initial Python/API contributions and prototype or improve a priority retrieval or LLM workflow.
• Add foundational tests and quality measurements for early AI capabilities.

Day Sixty

• Own significant RAG, agent, guardrail, or evaluation components and integrate them with the application.
• Use system tests and user feedback to improve grounding, accuracy, completeness, and appropriate scope.

Day Ninety

• Take end-to-end ownership of core AI/backend capabilities from design through production-ready validation.
• Help establish repeatable evaluation, monitoring, and improvement practices for the greenfield AI layer.
