Senior Engineer – Generative AI & Agentic Frameworks
NavitasPartnersNavitas Partners, LLC is a certified WBENC and one of the fastest-growing Technical / IT staffing firms in the US providing services to numerous clients. We offer the most competitive pay for every position. We understand this is a partnership. You will not be blindsided and your salary will be discussed upfront.
Role Description We are looking for a Senior Engineer to lead development of Generative AI and agentic frameworks supporting enterprise-scale AI transformation. - Architect and implement GenAI and agent-based solutions - Develop scalable AI pipelines integrated with cloud platforms - Ensure governance, reliability, and performance of AI systems - Collaborate across teams to deliver enterprise AI capabilities Qualifications - Strong experience in GenAI, AI/ML, and LLM technologies - Cloud platform expertise (AWS, Azure, GCP) - Proven hands-on development experience Requirements - Experience with Python, PyTorch, LangChain, and MLOps - Data Engineering exposure: Databricks, Snowflake, Synapse, BigQuery - Alignment with cloud/data platform architecture strategies - Knowledge of Responsible AI, governance, and compliance Company Description
• The Forward Deployed AI Engineer will work directly with clients and senior engineers to build AI-powered systems inside real enterprise environments. • Understand operational workflows and convert them into technical artifacts. • Connect to real enterprise systems and data sources. • Build context-aware AI agents, retrieval systems, and automation prototypes. • Help move the best prototypes toward reliable production deployments. • Help ingest, clean, structure, and connect data from enterprise systems into context graph. • Build AI pipelines and agent-based systems that can reason over enterprise context, identify patterns, surface workflow gaps, and suggest or trigger automations. • Integrate with client infrastructure such as databases, APIs, cloud storage, document repositories, analytics tools, ticketing systems, and internal applications. • Rapidly build proof-of-concepts that show how AI can improve a client's operations. • Work with senior engineers and business stakeholders to translate ambiguous operational problems into technical designs, data models, prompts, pipelines, and deployed applications. • Help build reliable, maintainable systems that can run in production environments, including client cloud environments when needed.
Role Description We're building a network of AI Engineers who can design, build, and integrate practical AI features into existing products. We're looking for people to collaborate with on a freelance basis - part-time or full-time, depending on project needs. This role is focused on delivery, not ML research - you don't need to be a data scientist. What matters most is your engineering foundation and your ability to use AI to solve real business problems.
