Senior Python Application Developer (Backend & Data-Focused)

Be Part Of a High-Performing Technology Team

This role supports a global financial services organization operating in a highly regulated, enterprise-scale environment. The technology team focuses on building and modernizing core platforms that support data-driven decision-making, internal applications, and business-critical workflows. The environment is fast-paced, delivery-oriented, and emphasizes strong engineering fundamentals, clean architecture, and hands-on problem solving.

Teams work closely with business and technical stakeholders to design scalable systems that balance performance, reliability, and long-term maintainability. Engineers are expected to think beyond code delivery and contribute to system design decisions, architectural rationalization, and technical clarity across the organization.

What s In Store For You

This is a senior, hands-on engineering role with direct ownership of application development from design through deployment. The engagement offers exposure to enterprise-grade systems, complex data integrations, and architecture-level decision-making. The hybrid model provides on-site collaboration while still allowing flexibility for focused development work.
