Staff ML Engineer - Production AI for Enterprise

Why Crucibl

Management consulting is a $400B industry built on selling intelligence-for-hire. The model is breaking - not slowly, but now. The biggest frontier in enterprise AI isn't better models. It's judgment at scale: taking the messy, ambiguous decisions that run 85% of the global economy and making them faster, crisper, and more defensible.

Crucibl is building that. We're profitable, growing fast, and delivering for Fortune 500 clients. We raised a $10M seed from Tier 1 VCs - then kept growing on revenue. The client pipeline is full. We're scaling to meet it.

What You'll Do

• Design and build the reasoning and modeling components at the core of our intelligence engine - retrieval, orchestration, evaluation, fine-tuning

• Take promising techniques from research and turn them into robust, production-grade systems

• Own the full loop: experiment, measure, ship, iterate on real client data

Make the Product Smarter

• Build and improve the models and pipelines that power judgment at scale for enterprise clients

• Instrument systems to catch failure modes early and turn them into concrete improvements

• Balance rigor with speed - our clients need answers now, not eventually

Partner with Founders

• Collaborate on roadmap, trade-offs, and technical vision

• Ship directly to enterprise clients - your work has immediate, measurable impact

Set the Bar

• Define what great applied science looks like in an AI-first organization

• Raise the bar for the team as it grows

Who You Are Must-Haves

• At least one undeniable signal of excellence - built and shipped ML systems at a top tech company, early applied scientist at a startup that built something real, notable open source work, or top-tier CS/ML program

• Strong fundamentals in ML/AI - you've taken models from prototype to production, not just notebook to paper

• Shipped meaningful ML-powered products end-to-end - not just features, but systems people rely on

• Comfortable with the full stack of applied work: data, modeling, evaluation, deployment

Strong Signal

• Experience building LLM-powered products, pipelines, or agentic systems in production

• Experience with enterprise data systems or analytics infrastructure

• Has operated in a high-growth, high-ambiguity environment

• Thinks like an owner - big picture, not just your part

We're Not Looking For

• Scientists who need a full spec before starting - ambiguity is the job

• Coasters from large tech - we want people who shipped things that mattered, not maintained things that existed

• Pure researchers without product instincts - we build for real clients, not benchmarks

Who You'll Work With

Our founders bring deep technology experience (Google-scale systems serving hundreds of millions of users) and domain expertise in high-stakes business decisions from top consulting and private equity firms. You'll be the connective tissue between these worlds, and between the company we are today and the company we're becoming.
