Meet the Team
Core to the health and growth of our business, Millennium’s Information Technology organization develops the flexible, scalable technology and advanced proprietary systems that support the firm’s active, multi-manager platform, including next-generation analytical and trading capabilities. Our Central AI team has a broad mandate: bring AI to every function that runs the firm. That includes business development, alpha capture, execution services, risk management, finance, operations and middle office, legal, compliance, recruiting, and beyond. If a team here has a problem AI can solve, we figure out the right approach and ship the solution.
Our Israel office is located in the Bursa area of Ramat Gan.
This role is on-site.
As a global firm, proficiency in English is required.
About the Role
We're hiring Rapid Application Developers: forward deployed AI engineers who embed with a business team, learn how the work gets done, and build the system themselves. Most of what we ship is one of two things. The first is agentic systems that execute multi-step business processes end to end. The second is supervised machine learning over years of the firm's own labeled data. This is not a chatbot role. Sometimes the right answer is a simple script, and you'll say so.
Problems arrive as "this takes my team 20 hours a week," or "we have ten years of this data and no idea what's in it." You own everything from that conversation through architecture, deployment, evaluation, and iteration, then turn what works into reusable capabilities for the whole firm.
Who thrives here: builders who run their own lives on agents they made, track model releases because the deltas change what they can ship, and treat an AI system without an eval as a demo. Equally welcome are engineers with deep classical ML and algorithm backgrounds (perception, ranking, forecasting, optimization) now applying that rigor to agentic systems. The best people on this team hold both.
What you get: frontier model access across every major provider with real budget, years of proprietary labeled data as eval and training fuel, ship cycles measured in days rather than quarters, demanding users who will actually run your systems, and no platform team between you and production.
What You'll Do
What You Bring
Stack: Python-first, major cloud, frontier model APIs, modern agent tooling.
No finance background required. You'd rather say "it's at 70% accuracy and here's the failure analysis" than demo a cherry-picked success.
WHAT THIS ROLE IS NOT
Not pure research. Not prompt-only. Not wrapping a model API and calling it AI. Not dashboards-only. Not a role where requirements arrive fully specified, and not one where you hand off designs for someone else to build.
