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.

Key Competencies

Essential

8+ years' professional software development experience, with deep expertise in Python or another object-oriented language and demonstrated ability to become an expert-level Python engineer quickly

Track record of owning architecture and technical direction for systems used in production at scale, beyond the scope of a single team

Strong academic record with coursework focused on mathematical and computing content, e.g. Computer Science, Mathematics, Engineering, or Physics

Deep experience with best practices for testing, monitoring, deployment, and operating mission-critical production systems

Experience with distributed systems, orchestration, and large-scale performance optimisation

Proficient on Linux platforms with strong command of Git and modern engineering workflows

Deep knowledge of one or more relevant database technologies, spanning relational (e.g. Oracle, PostgreSQL, SQL Server, MySQL), NoSQL/document (e.g. MongoDB), or timeseries (e.g. ArcticDB) systems

Demonstrated experience designing for and working with large, complex data sets, both structured and unstructured

Proven ability to influence technical direction without formal authority, and to align stakeholders across teams with differing priorities

Experience mentoring engineers and elevating the technical capability of a team

Experience integrating tools like Claude Code, Cursor, or custom agentic workflows into a team's SDLC

Advantageous

Deep understanding of the Python scientific stack (pandas, numpy, scipy, scikit-learn)

Familiarity with related data platforms such as monitoring and metrics (e.g. Prometheus, InfluxDB), search and analytics (e.g. Elasticsearch), streaming (e.g. Kafka), or big data and distributed compute (e.g. Hadoop, Spark)

Knowledge of modern data engineering practices including ETL tooling, distributed storage and processing, and data warehousing

Significant contributions to open-source projects

Experience working with Large Language Models (LLMs), including applying them to engineering workflows or products

Experience in financial services, trading, or quantitative research environments

Experience defining or influencing engineering standards, guilds, or communities of practice across an organisation

Why Man Group?

Set technical direction on problems at the true cutting edge of technology and finance

Work alongside world-class engineers, researchers, and investment professionals - and shape how they work

Entrepreneurial, innovation-driven culture with small, agile teams and high autonomy
