New York, NY
Full-time
Onsite
Mid LevelPercepta is a company focused on transforming critical institutions with applied AI. They are seeking Machine Learning Engineers to work directly within customer teams to define and deliver high-impact AI systems, designing and shipping production-grade AI agents and workflows.
Computer Software
Responsibilities
Engineer and optimize AI/ML systems: Build end-to-end ML pipelines for data ingestion, training, evaluation, and deployment. Adapt and extend LLM models with fine-tuning, distillation, retrieval systems, and tool-use to solve domain-specific problems
Evaluate AI systems rigorously: Develop custom evaluations to ensure models succeed in real-world environments
Bring frontier methods into practice: Track the latest techniques in areas like RAG, tool use, multi-step agent orchestration, fine-tuning methods, and evaluation frameworks - and apply them to specific customer challenges
Collaborate across product and research: Partner with research and product teams to turn frontier techniques into production-ready features and workflows
Advance our core product: Encode the lessons from our customer engagements in our Mosaic product, consistently contributing reusable ML components, infrastructure abstractions, and performance improvements
Qualification
Required
AI-nativeness: You're excited about the potential for AI to transform businesses and want to play a hands-on role in bringing frontier technology into critical institutions
Strong ML foundations with hands-on experience building and deploying production models / AI systems
Being generative and collaborative: You love constantly jamming on new “what if” ideas with teammates and partners to bridge applied engineering, product, and research efforts
Extreme ownership: You're willing to jump in and love being the one on the hook. You aren't going to wait to be pointed at a task—you're going to identify what you think we should do next, and then do it
Execution excellence and speed: You can build stuff in messy environments and know how to get code written and shipped quickly. You can hold the balance of speed and quality and know when to push the pace vs. when to slow down
Customer-obsession and respect: You're motivated by understanding customer pain points and iterating directly with end users to deliver wins quickly
Preferred
Hands-on experience with LLM tooling (e.g., LangGraph, Mastra, Agents SDK)
Experience fine-tuning, distilling, and deploying LLMs or other foundation models in production
Background in retrieval, RAG pipelines, or multi-step agent design (including tool use and human-in-the-loop systems)
Strong engineering foundations in Python/TypeScript, cloud deployment (AWS/GCP/Azure), and modern MLOps/DevOps tooling
Prior startup or founding engineer experience, balancing craft, ownership, and speed
