You will build and fine‑tune Retrieval‑Augmented Generation (RAG) pipelines, Agentic AI pipelines, and large language model (LLM) solutions that solve concrete business problems. You will work closely with product owners, data scientists, and senior engineers to ship reliable, scalable AI services. Successful candidates will have demonstrated the ability to build AI solutions to solve customer problems. They will have a track record as an effective communicator and problem solver who is able to develop and maintain good working relationships with internal and external stakeholders. The selected candidates will work closely with AI engineers and business partners to accomplish the following:

• Work with customers to define, develop, and deliver AI solutions to meet mission and sector needs.

• Design, develop, document, test and debug applications software and systems that contain logical and mathematical solutions.

• Collaborate with cross-functional teams to deploy machine learning algorithms for testing and is in production systems.

• Maintain understanding of the cutting-edge technologies in AI/ML.

• Regularly demonstrate progress to customers.

• Rapid Prototyping & Delivery – Turn medium‑priority use‑case specifications into working AI prototypes within 2‑4 weeks and iterate to production quality.

• RAG, Agentic AI, and LLM Development – Design and implement retrieval‑augmented generation pipelines and agentic workflows integrating pretrained LLMs (e.g., GPT‑4/5/OSS, Llama) though APIs and self-hosted model deployments.

• Model Integration – Embed fine‑tuned models into existing micro‑service architectures (REST/GraphQL, gRPC) and expose them via APIs or internal SDKs.

• Performance & Reliability – Set up monitoring, logging, and automated testing (unit, integration, latency) for AI services; troubleshoot model drift and latency issues.

• Data Preparation – Collaborate with data engineers to curate, clean, and annotate domain‑specific datasets for fine‑tuning and evaluation.

• Documentation & Knowledge Sharing – Write clear technical documentation, create example notebooks, and mentor junior teammates on AI best practices.

• Continuous Improvement – Stay current with the latest LLM research, open‑source tools, and industry trends; propose upgrades to the AI stack.
