Generative AI Application Engineers (US Cit / PR to pass security clearance)

We are seeking to hire several Generative AI Application Engineers to join our teams working on a new multi-year award we have within a Federal Gov’t Agency.  These roles are 100% remote.

Being a US Cit or Permanent Resident is required for passing the security clearance to work on this program.

This position pays a strong salary package with full benefits (including choice of healthcare plans, dental, vision, life insurance, 3 weeks PTO, 11 Paid Federal Holidays, and a matching 401k).

An option for working on an hourly rate is also available for those not needing a full benefits package.

Role Title: Generative AI Application Engineer (Mid-Level)

Experience Level: 2–5 years

Project Focus: Applied GenAI Development for Enterprise Applications

Role Summary:

The Generative AI Application Engineer builds and integrates AI-enabled capabilities into enterprise applications as part of the modernization program. This role focuses on applied AI development—prompt engineering, retrieval-augmented generation (RAG), vector search integration, and LLM orchestration—rather than research model development. The engineer works under the direction of a Senior GenAI Lead and collaborates closely with APEX developers, data integration teams, DevOps, and QA to deliver secure, reliable, production-ready AI features.

Key Responsibilities:

Applied GenAI Development

·        Implement components of RAG pipelines, including embeddings, vector search, and hybrid retrieval logic.

·        Develop prompt templates, grounding strategies, guardrails, and LLM orchestration flows based on patterns defined by the GenAI Lead.

·        Integrate GenAI services with enterprise applications (e.g., Oracle APEX) through REST APIs, backend microservices, or PL/SQL callouts.

·        Implement guardrails, validation logic, fallback behaviors, and secure error-handling for AI-driven workflows.

Integration & Data Enablement

·        Integrate applications with vector databases or vector search functionality (Oracle Database preferred).

·        Collaborate with data engineering teams to source structured data, understand schemas, and define access patterns for AI workloads.

·        Create and maintain evaluation datasets; support retrieval quality metrics and prompt regression testing.

DevOps, Testing & Governance

·        Work with DevOps and cloud engineering teams on deployment pipelines, secrets management, configuration, and monitoring for AI services.

·        Support QA engineers in developing automated tests for GenAI-enabled functionality.

·        Ensure AI components meet enterprise requirements for security, auditing, logging, and cost governance.

Collaboration & Delivery

·        Participate in Agile delivery processes, including sprint planning, demos, and refinement.

·        Partner with application developers, architects, QA testers, and business analysts to deliver cohesive end-to-end features.

·        Contribute to documentation, design patterns, and runbooks to support long-term operational readiness.

Required Qualifications:

·        2–5 years of software engineering experience in application or backend development.

·        Hands-on experience building applied GenAI solutions (RAG, prompt engineering, LLM orchestration).

·        Experience using LLM APIs (e.g., OCI Generative AI, OpenAI, Azure OpenAI, Anthropic).

·        Proficiency with Python or Node.js for backend and integration development.

·        Familiarity with structured data, SQL, and working with relational databases.

·        Experience integrating with vector databases or vector search functionality (Oracle Database preferred).

·        Understanding of evaluation methods such as retrieval precision/recall, grounding accuracy, or automated prompt testing.

·        Ability to work effectively with cross-functional teams (APEX developers, Data Engineers, DevOps, QA).

·        Strong communication and documentation skills.

Preferred Qualifications:

·        Experience with Oracle Cloud Infrastructure (OCI), Oracle APEX, or Autonomous Database.

·        Hands-on experience with vector search in Oracle Database 23c or Autonomous Database.

·        Familiarity with enterprise security practices, API gateways, and secrets management.

·        Exposure to guardrail frameworks, grounding techniques, or advanced RAG patterns.

·        Experience building user-facing AI features within enterprise environments.

If qualified and interested, please send an updated resume along with rate/salary requirement and we will follow up quickly to discuss further details and move forward with your interview process.
