Product Manager (AI Platforms)

Lexsi Labs is one of the leading frontier labs focusing on building aligned, interpretable, and safe Superintelligence. Most of our work involves creating new methodologies for efficient alignment, interpretability-led strategies, and foundational model research across enterprise and tabular data. Our mission is to build AI systems that are powerful, transparent, and trustworthy by design.

Our team thrives on deep technical rigor, hands-on ownership, and a strong bias toward building systems that actually work in production. At Lexsi.ai, we operate with a flat structure, fast feedback loops, and an expectation that everyone deeply understands what they ship.

Product Manager

strong AI/ML background

Responsibilities

• Own product requirements and execution for AI/ML and platform-heavy features from problem definition to production rollout.
• Translate complex AI behavior into precise, testable product specifications and acceptance criteria.
• Work deeply with AI Researchers to collect the details of the components created and AI engineers and SDEs to ensure implementations match intended algorithms, assumptions, and constraints.
• Define what “correct” means for each feature, including metrics, evaluation logic, edge cases, and failure modes.
• Work with QA and testing teams to design meaningful test strategies that reflect real ML behavior, not just happy paths.
• Break down ambiguous product roadmaps or experimental ideas into shippable, scalable product increments.
• Prioritize features and technical debt based on user impact, system risk, and long-term platform scalability.
• Act as the quality bar-raiser by catching conceptual gaps early and preventing flawed features from shipping.

Requirements

• Prior experience as an ML engineer, data scientist, or research engineer.
• Experience building developer platforms, ML tooling, or infra-heavy products.
• Strong foundation in Deep Learning, LLMs, machine learning or data science with hands-on experience building or deploying AI systems.
• Familiarity with testing strategies for ML systems, including offline evaluation, simulation, and monitoring.
• Experience working closely with AI engineers on model behavior, evaluation, and performance trade-offs for multiple modalities - LLMs, Tabular, Text and Agentic systems
• Ability to reason about ML correctness, limitations, and failure modes, not just UX or timelines.
• Experience owning product features end-to-end, either formally as a PM or informally as a technical lead.
• Comfortable writing precise specs, acceptance criteria, and evaluation plans that engineers and testers can execute against.
• Strong communication skills across research, engineering, QA, and leadership without dilution of technical meaning.

Nice to Have

• Exposure to interpretability, alignment, model observability, or AI safety work.
• Ex Founder or Startup experience where product ambiguity and technical depth coexist.

What Success Looks Like

• Features ship with clear intent, correct behavior, and well-defined evaluation criteria.
• QA and testing teams understand what they are testing and why it matters.
• Engineering rework drops because specs capture real constraints upfront.
• Product velocity increases without sacrificing correctness or trust.

PS: AI Background is a must for this role.
