Job Title: Senior Python Developer
Location: London
Length: 6 months
PAYE only
Overall purpose of the role
We are looking for a highly skilled Python Engineer to join our Macro Flow Rates team for a 6 month period.
This isn't a role for someone looking to build complex new pricing models; instead, it is a mission-critical engineering and automation project.
You will be responsible for modernizing our tech stack, migrating us from legacy C++ environments and manual spreadsheets toward a streamlined, Python-centric ecosystem.
Key Accountabilities:
Legacy Migration: Lead the rebuild and migration of an established C++ strategy testing environment into a modern Python framework.
Tooling & Solutions: Transition a critical Cross-Currency Swaps desk spreadsheet into a robust, scalable Python-based solution.
Process Automation: Identify and automate repetitive reporting tasks currently sent to Senior EM Stakeholders, freeing up the team for higher-value activities.
System Integrity: Ensure the accuracy of "Flow" product calculations throughout the migration process.
Key Skills:
Polyglot Proficiency: A balanced 50/50 split in expertise between C++ and Python.
Macro Product Knowledge: Deep understanding of Rates and FX products (Flow). You should be comfortable explaining the nuances of these instruments and how they are deployed.
Proven Track Record: Experience building or migrating test environments for similar financial products in the past.
Automation Mindset: A desire to eliminate "tedious" manual calculations through elegant code.
Education: A degree in a STEM subject or Computer Science.
About Barclays

Diversity
Barclays aims to foster a culture where individuals of all backgrounds feel confident in bringing their whole selves to work, feel included and their talents are nurtured, empowering them to contribute fully to Barclays vision and goals.
Hybrid Working
Barclays is currently in the early stages of implementing a hybrid working environment, which means that many colleagues spend part of their working hours at home and part in the office, depending on the nature of the role they are in. Barclays is flexible on how this works and it may continue to change and evolve. Depending on your team, typically this means that colleagues spend a minimum of between 20% to 60% of their time in the office, which could be over a week, a month or a quarter. However, some colleagues may choose to spend more time in the office over a typical period than their role type requires. Barclays also has a flexible working process where, subject to business needs, all colleagues globally are able to request work patterns to reflect their personal circumstances
