Software Development Engineers are expert problem-solvers and builders who design, implement, and improve software applications and systems. In this role, engineers spend approximately 60–75% of their time coding, working hands-on with code, data, and modern tools (including AI-assisted development, cloud services, and automation frameworks) to deliver secure, scalable, and high-quality technology solutions that drive business outcomes in the fintech sector. They collaborate with cross-functional teams – product managers, designers, data scientists, QA, operations, and compliance – to translate business requirements into robust technical solutions, all while adhering to best practices, security standards, and regulatory requirements.

All roles require digital fluency, including the ability to work with emerging technologies such as Generative AI tools (e.g. ChatGPT, Microsoft Copilot) to support everyday work.
Key Responsibilities:

• Collaborate with stakeholders to interpret requirements for project components and incorporate feedback into future designs or solution fixes.

• Participate in system design and architecture, refining code plans and contributing to design documentation.
• Contribute to project estimation and escalate issues that may cause delays.
• Develop, implement, and maintain code for products, services, or components, applying coding patterns, guidelines, and best practices.
• Apply debugging tools to verify assumptions and proactively flag issues before they occur.
• Participate in code reviews to ensure coding standards are followed and address routine pull requests.
• Create test plans and configure testing procedures to identify and resolve defects for multiple features.
• Respond to support requests during on-call rotations, troubleshooting issues and deploying fixes under guidance.
• Leverage and build knowledge of software developer tools to create, debug, and maintain code for components.
• Remain current in skills by investing time in training resources to improve product availability, reliability, efficiency, observability, and performance.
