The Role

We're seeking a Staff Python Engineer to provide technical leadership across our technology organisation, working on high-impact challenges spanning systematic trading, quantitative research, our petabyte-scale data platform, and AI solutions.

This is a senior individual-contributor role for an engineer who sets technical direction, not just delivers against it. You will shape architecture across team boundaries, raise the engineering bar through hands-on mentorship and review, and act as a trusted technical partner to engineering leadership, researchers, and traders. You'll be given significant autonomy to identify and drive the highest-leverage technical initiatives, while remaining deeply hands-on in design and code.

Role Responsibilities

Own architectural direction for critical systems, making build-vs-buy and long-term design decisions that span multiple teams and years, not just sprints
Design and build scalable backend systems, APIs, and distributed compute applications that underpin trading and research infrastructure, with a focus on performance, resilience, and observability at scale
Build and evolve high-performance data pipelines for petabyte-scale financial datasets, working across timeseries, SQL, and NoSQL databases
Act as a technical escalation point and thought partner for engineers, researchers, and platform teams, translating ambiguous or conflicting requirements into coherent technical strategy
Lead by example on engineering craft: set standards for testing, code review, and production readiness, and raise the bar through mentorship of engineers at all levels
Drive cross-team technical initiatives from proposal through delivery, including proofs of concept, migrations, and platform-wide improvements
Participate in production support rotations and contribute to incident response and postmortems for the most critical systems
Champion the adoption of AI-assisted development tools and agentic engineering practices across the team, and help define how the organisation uses them responsibly at scale

Our Technology

You'll work in a modern, Linux-based infrastructure where Python is the primary development language, utilising the full scientific stack including pandas, numpy, scipy, and scikit-learn. A key component of our data infrastructure is ArcticDB (https://arcticdb.io/), our internally developed DataFrame database that you'll use and help evolve. We maintain a dynamic technology landscape, continuously evaluating and adopting new tools and libraries that enhance our capabilities. man.com/technology

Our Sofia Office

This role sits within our growing Sofia office, one of Man Technology's fastest-expanding engineering hubs outside London. We recently moved into a newly built, purpose-designed office in the city as part of our long-term investment in the team here. Beyond day-to-day delivery, our Sofia engineers help raise Man Group's profile as a technology employer locally - engaging with the Bulgarian tech community through university partnerships, hackathons, and local meetups.
