Global Markets Technology

We are looking for an experienced Senior Software Engineer to join our Global Markets Technology team, reporting directly to a Development Manager. This role covers the full software development lifecycle, including analysis, development, testing, and production support. We operate in true end-to-end teams – there are no separate support teams.

About the Project

As a Senior Software Engineer, you will be involved in all stages of application development. You will work in small, agile teams of 4–6 engineers with a dedicated Product Owner. While most teams are co-located, collaboration with geographically distributed teams is part of the role.

• Take business requirements, break them down into user stories, and deliver them iteratively into production

• Provide ongoing production support – “you build it, you support it”

• Identify areas of technical debt and ensure a healthy balance between new functionality and technical improvements

• Design solutions for new features in line with technology standards and constraints

• Pair program and collaborate closely with other team members

• Provide guidance and mentorship to junior engineers

Skills & Experience We Require

• 5+ years of strong experience with Python

• Solid hands-on experience with Pandas, NumPy, Flask and/or Django

• Good understanding of Agile development methodologies with a delivery-driven mindset

• Ability to work effectively with both local and global teams

• Leadership skills and experience supporting junior team members

• Flexible approach to ownership and delivery responsibility

• Open-minded, proactive, and eager to learn and grow

• Strong written and spoken English communication skills

Nice to Have

• Experience in Machine Learning, NLP, or AI

• Experience building FX or Rates pricing systems

• Experience with KDB or cloud-based solutions

• Knowledge of JavaScript and/or Vue.js
