About The Position

This is an 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.

Requirements

2+ years of professional software engineering experience with a strong delivery track record
Strong Python: Well-tested, modular production code. Comfortable with dataclasses, type hints, OOP, design patterns
Financial services experience — particularly portfolio management, risk, or investment operations
Pandas/NumPy proficiency: Building efficient data pipelines and transformations at scale
AI/LLM tooling — experience building with or integrating LLM-based tools. 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

Nice To Haves

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

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
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
Own production stability for systems in your portfolio — investigate data quality issues, triage support requests, manage incident response
Maintain documentation and operational processes
