Job Description

Job Summary
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 determine requirements for product components and incorporate feedback into future designs or solutions.
- Translate functional requirements into system designs and communicate component interactions, ensuring alignment with business needs and timelines.
- Design and develop product components, refine code plans, and lead design reviews to ensure completeness and adherence to requirements.
- Contribute to project estimation, considering delivery costs and escalating issues that may cause delays.
- Lead by example in creating, implementing, and maintaining extensible, reusable code, and drive code quality through metrics and best practices.
- Apply debugging tools to resolve moderately complex issues and identify opportunities for automation across products.
- Lead code reviews, ensuring adherence to coding standards and providing feedback to team members.
- Create complex test plans, identify test gaps, and proactively address defects to minimize customer impact.
- Leverage data analysis and monitoring standards to identify patterns and defects in all environments.
- Respond to incidents during on-call rotations, troubleshoot complex issues, and assist in incident response and resolution.
- Build, enhance, and identify new developer tools to support programs and applications.
- Proactively seek new knowledge and adapt to trends and technical solutions to improve product performance and recommend resources to other engineers.

This is a hybrid position. Expectation of days in office will be confirmed by your hiring manager.
