Lead Principal AI Engineer
Software Engineering, Data Science
United States
Role Overview
We are seeking a Lead Principal AI Engineer who brings a foundational, mathematically
grounded understanding of classical Machine Learning, combined with deep hands-on
expertise in modern Generative AI, Large Language Models (LLMs), and Agentic Frameworks.
In this role, you will serve as both a technical authority and a strategic leader. You will architect
end-to-end AI systems--from dataset curation and fine-tuning to building agentic workflows
and automated evaluation suites--while working directly with enterprise customers to translate
complex business problems into production-grade solutions.
At iBase-t We are building Frontier--the industry’s first true, purpose-built AI solution for
Aerospace & Defense (A&D) manufacturing. A&D manufacturing represents one of the most
complex, high-stakes engineering environments in the world, where precision, traceability, and
strict compliance are non-negotiable.
We are seeking a Lead Principal AI Engineer to pioneer this new vector. You will be a
foundational technical architect for Frontier, combining deep, mathematically grounded
Machine Learning with cutting-edge Generative AI, LLMs, and autonomous agentic
frameworks.
In this role, you will bridge the gap between advanced AI research and real-world industrial
impact--architecting agentic workflows, domain-specific fine-tuning pipelines, and evaluation
suites designed to solve complex manufacturing, quality engineering, and operational
challenges while interfacing directly with key customer leadership.
Key Responsibilities
AI Architecture & Agentic Frameworks
● Design, build, and deploy production-grade agentic frameworks and multi-agent
workflows from scratch using clean, scalable Python code.
● Architect custom tool-use protocols, memory systems, and planning mechanisms for
autonomous AI agents.
● Bridge classical ML approaches with generative paradigms to build hybrid, resilient
systems.
LLM Lifecycle, Fine-Tuning & Evals
● Drive dataset curation, data synthesis, instruction-tuning, and domain-specific dataset
generation pipelines.
● Fine-tune open-source and proprietary models using advanced techniques (e.g.,
LoRA/QLoRA, PEFT, DPO/RLHF).
● Build rigorous, repeatable evaluation frameworks (e.g., benchmark design,
LLM-as-a-judge, custom metric scoring) to ensure reliability, safety, and performance.
Technical Leadership & Problem Solving
● Serve as the principal technical lead across cross-functional engineering efforts, setting
coding standards, architecture patterns, and technical strategy.
● Break down complex, ambiguous business challenges into actionable, high-impact
machine learning architectures.
● Mentor senior and mid-level engineers in production ML best practices.
Customer Engagement & Technical Strategy
● Act as a primary technical lead in client-facing environments, presenting architectural
designs, articulating trade-offs, and driving integration with customer engineering teams.
● Gather requirement feedback from stakeholders to directly shape product roadmaps
and technical specs.
Required Qualifications
● Education: Master’s or Ph.D. in Computer Science, Machine Learning, Data Science,
Electrical Engineering, or a related quantitative discipline.
● US Experience: Minimum 5+ years of professional engineering experience either as
ML engineer or AI engineer.
● Core ML First: Strong, foundational understanding of core machine learning principles
(optimization, statistical modeling, feature engineering, classic supervised/unsupervised
learning, and deep learning architectures) prior to LLMs.
● LLM & Fine-Tuning Mastery: Hands-on experience with dataset curation,
parameter-efficient fine-tuning (PEFT), and developing comprehensive model evaluation
(evals) methodologies.
● Agentic AI Systems: Proven track record of designing, building, and deploying AI agent
architectures, autonomous workflows, and tool integration frameworks.
● Software Engineering: Advanced Python proficiency, with strong software engineering
practices (clean code, CI/CD, modular architecture, performance profiling).
● Client-Facing Leadership: Excellent communication and consultative skills with
experience interfacing directly with external clients, technical decision-makers, and
executive stakeholders.
Preferred Qualifications
● Prior exposure to manufacturing execution systems (MES), PLM/ERP systems, or
industrial operations context.
● Experience deploying AI models within secure, air-gapped, or highly compliant
environment constraints (e.g., FedRAMP, ITAR).
● Background in vector databases, hybrid search architectures, and complex graph-based
