Leveraging your deep expertise in .NET technologies, you will contribute to the entire software development lifecycle, from architectural design to implementation and maintenance. This role offers a unique opportunity to work on complex, mission-critical projects within the financial services sector, collaborating with a global team of talented engineers and business stakeholders.
  • You will be responsible for designing, developing, and maintaining robust RESTful APIs and sophisticated backend services, primarily utilizing C# and the .NET / .NET Core framework. Your contributions will be crucial in building scalable and high-performance applications that meet the stringent demands of enterprise environments.
  • A significant aspect of your role will involve contributing to the enterprise application architecture. This includes designing and implementing microservices and distributed systems, ensuring they are resilient, maintainable, and performant. You will apply your knowledge of architectural patterns to create solutions that are both innovative and practical.
  • We expect you to champion and implement software engineering best practices. This means adhering to principles such as Clean Code, SOLID, and established Design Patterns. Your commitment to code quality, readability, and maintainability will be paramount in fostering a high-performing development environment.

  • Performance optimization is a key focus. You will be tasked with query optimization and performance tuning, particularly for large-scale data environments. Your ability to identify bottlenecks and implement effective solutions will directly impact the performance and scalability of our applications.
  • While your primary focus will be on the backend, you will also support frontend components as needed to ensure full-stack delivery. This involves working with HTML, CSS, and JavaScript, demonstrating a well-rounded understanding of web application development.
  • You will play a vital role in integrating internal and external enterprise systems and services. This requires a thorough understanding of various integration patterns and the ability to connect disparate systems seamlessly.
  • This position demands experience in mission-critical and high-availability enterprise environments. You will be working on systems where reliability and uptime are of utmost importance, requiring a meticulous approach to development and testing.
  • Collaboration is key. You will work closely with technical teams, including architects, developers, and QA engineers, as well as business stakeholders. Your ability to communicate effectively and understand business requirements within financial platforms and banking systems will be essential for project success.
  • You will be part of an AI-first global tech company with over 25 years of engineering leadership, working on projects for Fortune 500 clients.

  • Your work will directly influence the success of our clients' digital transformation initiatives, enabling them to build what's next in their respective industries. You will be empowered to make significant contributions and see the tangible impact of your engineering efforts.
  • We foster an environment where trust, respect, and purpose guide our actions.
