Sr. Product Manager (AI Platform and Generative Models)

We're a fast-growing and profitable startup building the defining company at the intersection of AI, apparel, and culture. We move at a blinding pace, operate in one-week release cycles, and are looking for a builder with a founder's mentality to join our core team. We are not iterating; we are inventing. If you're tired of big-tech bureaucracy and want to build a rocketship from the ground up, this is your call.

This is not a typical Product Manager role. We are looking for a deeply technical product leader to architect the core intelligence of our company. You will own the vision, strategy, and execution of our foundational AI platform, encompassing everything from proprietary large-scale models to the APIs that expose their capabilities to our consumer products and developer ecosystem.

Your mission is to build the brain and the nervous system of our entire product suite. You will guide the development of our in-house Large Language Models (LLMs) and imaging models, define the roadmap for agentic AI systems, and create a world-class platform that unlocks capabilities our users haven't even imagined yet. You are not managing a product; you are building the future of our company's technological moat.

Basic Qualifications

Bachelors Degree Required in Computer Science or related field.

6+ years experience in product management

Hands-on AI / ML Background : You have a past life as an ML Engineer, AI Researcher, or Data Scientist. You have hands-on experience building and shipping machine learning models. You must be able to command the respect of our senior AI engineers through your deep technical credibility.

Full-Stack Model Expertise : You understand the entire lifecycle of large-scale models (LLMs, Diffusion Models, etc.) from a first-principles level. This includes :

Training & Data : You can strategically guide decisions on data acquisition, pre-training vs. fine-tuning, and novel training methodologies.

Inference & Optimization : You deeply understand the trade-offs between latency, cost, and performance, and can drive the roadmap for model quantization, distillation, and efficient serving.

Mastery of Applied AI Craft : You know how to turn a powerful but raw model into a magical, reliable product. You are an expert in :

Evals : Designing and implementing robust, multi-modal evaluation frameworks (both automated and human-in-the-loop) to rigorously measure and improve model quality.

Agentic Systems : Architecting and building AI agents that can reason, plan, and use tools to accomplish complex tasks.

Advanced Prompting : You are a master of prompt engineering, including sophisticated techniques like meta-prompting and Chain of Thought to elicit the best possible performance from models.

Platform & API Architecture : You are a true platform builder. You know how to design clean, scalable, and intuitive APIs that developers love. You obsess over developer experience (DX), documentation, and building a platform that accelerates the entire organization.

Proven AI Shipping Experience : You have a track record of shipping V1 AI-powered products, from consumer-facing features to developer-level platform services.

Strategic & Systems Thinking : You can reason from first principles about the long-term trajectory of AI. You can connect advancements in research to concrete product opportunities and build a coherent technical strategy that spans multiple years.

Exceptional Technical Communication : You can effortlessly translate the most complex AI concepts to any audience. You can debate RLHF implementation details with the research team and then explain the business impact of a new model to the executive team in the same day.

MLOps Acumen : You understand the infrastructure that underpins modern AI and can contribute to the strategy for our tooling, deployment, and model monitoring systems.

A "Wartime" Owner Mentality : You are an independent, relentlessly resourceful operator. You have an obsessive bias for action and run through walls to get the job done. You see a technical frontier, you chart a path, you rally a team, and you conquer it.

Preferred Qualifications

Startup DNA : You've worked at a seed or Series A startup or have tried to build your own thing.

Research Contributions : You have published papers at top AI conferences (e.g., NeurIPS, ICML) or have made significant contributions to major open-source AI projects.

AI Ethics & Safety : You have a strong and nuanced understanding of the risks and ethical considerations of building powerful AI systems.

Hardware Knowledge : You understand the underlying hardware (GPUs, TPUs, interconnects) and how it impacts model architecture and performance.

This Role Is Not a Fit For You If...

You see product management as just writing tickets. Your job is to be the technical and strategic visionary for our core AI.

You are a "glorified project manager job is to define the what and the why with extreme technical clarity, not just track the how.

You are afraid to get your hands dirty with technical details. You must be able to read a research paper and immediately grasp its product implications.

You feel your job is to "manage" engineers. Your job is to empower our world-class AI team with a compelling vision and deep technical partnership.

You want to wait for the technology to be perfect. We ship and iterate in one-week cycles, even on the bleeding edge of AI.
