Cititec Talent is working with a global trading and investment firm that is looking for a Senior Python Developer to join its core technology team. This is a hands-on, full-stack engineering role that blends application development, data engineering, and tooling to directly support trading and commercial teams.

You’ll be involved in both front and middle office initiatives, with a focus on performance, scalability, and clean architecture. The role includes building tools for real-time decision-making and data processing, making it well-suited to developers with experience in risk, pricing, or market-facing systems.

While Python is the main language, candidates with strong object-oriented backgrounds (e.g., Java or C#) who have transitioned to Python are encouraged to apply.

Responsibilities:

• Design, build, and maintain performant and scalable Python applications used by trading and commercial users
• Develop robust data pipelines and workflows using modern Python tools and frameworks
• Work closely with front office and middle office stakeholders to deliver business-critical tools and systems
• Contribute across the entire SDLC – from requirement gathering and design to deployment and support
• Implement engineering best practices: automated testing, version control, code review, and CI/CD pipelines
• Collaborate with cross-functional teams in a fast-paced, delivery-focused environment

Key Skills & Experience:

• Strong Python development skills, including use of Pandas, NumPy, and similar libraries
• Proven experience building data engineering pipelines and working with relational databases (PostgreSQL, SQLAlchemy)
• Exposure to front office trading systems, risk tools, or other market-facing applications is a strong plus
• Solid understanding of object-oriented design principles
• Comfortable with modern Python web frameworks (e.g., FastAPI)
• Familiarity with async programming (asyncio, multithreading)
• Exposure to tools like Airflow for orchestration and Kafka for messaging/event-driven architecture
• Experience working in cloud-based environments, preferably AWS
• Docker/Kubernetes experience is a plus
• Excellent communication skills and ability to work closely with business teams
