About the Role This is a senior engineering role sitting at the intersection of Man Group's Discretionary (public markets) and Solutions technology teams in New York. You will be the primary NY-based engineer supporting portfolio managers, analysts and quants functions across both business lines. The role spans Python data pipelines and analytics platforms serving Discretionary investment teams — equities, credit, and alternatives — alongside Python systems powering Solutions' fund analytics, portfolio management, and reporting infrastructure. You'll work hands-on building and operating production systems while acting as the key technical liaison for NY-based stakeholders. What You'll Do Development & Delivery (70%) • Build, extend, and maintain Python data pipelines using Pandas, NumPy, and internal libraries • Develop and enhance portfolio analytics, risk reporting, and fund data platforms • Contribute to AI-powered tools for investment teams — research databases with vector search, AI integrations for portfolio managers and analysts • Build and maintain FastAPI and Flask backends and React/TypeScript frontends using our shared component libraries • Deploy services to Kubernetes; manage Airflow DAGs for scheduled data workloads • Collaborate with London and Sofia-based engineers on cross-team initiatives Stakeholder Engagement (20%) • Serve as the primary technical contact for NY-based Discretionary and Solutions stakeholders • Gather requirements, translate business needs into technical solutions, and manage expectations • Work directly with portfolio managers, analysts, and quants — understanding their workflows is as important as writing the code Production Operations (10%) • Own production stability for systems in your portfolio — investigate data quality issues, triage support requests, manage incident response • Maintain documentation and operational processes Our Tech Stack • Python (primary), TypeScript/React • Data: Pandas, NumPy, Kafka • Backend: FastAPI, Flask • Frontend: React, Streamlit dashboards, Tableau • Infrastructure: Kubernetes, Airflow • AI tooling: Claude Code, LLM agents, vector search, RAG — we actively build and ship AI tools for our investment teams Essential Skills & Experience • 5+ years of professional software engineering experience with a strong delivery track record • Strong Python: Well-tested, modular production code.

We're active early adopters of AI-assisted development and are building AI agents for our investment teams • Solid testing discipline: pytest, unit tests, integration tests — you write tests as a matter of course • Comfortable in a Linux environment with Git, virtual environments, and CLI tooling • Strong communicator: You can explain technical decisions to non-technical stakeholders concisely, and you view stakeholder interaction as integral to good engineering — not overhead • Self-directed: You manage your own priorities, flag blockers early, and drive work to completion with appropriate autonomy • Degree in a STEM subject or equivalent practical experience Highly Desirable We don't expect all of these — but they'll help you hit the ground faster: • React/TypeScript for frontend development • Experience with web APIs: Building and consuming RESTful services (FastAPI, Flask, or equivalent) • C#/.NET familiarity — some Solutions systems are built in .NET. You won't be the primary .NET engineer, but being able to read and navigate the codebase is valuable • Kubernetes & containerisation — deploying and troubleshooting services in k8s • Airflow — building and maintaining scheduled data pipelines • Distributed systems concepts — messaging architectures, event-driven design, caching strategies • Experience working with geographically distributed teams — London will be your primary collaboration hub The anticipated based salary range for this position is listed below.
