• Build and improve software components, services, APIs, and shared libraries as part of the engineering team.
• Create automated tests and contribute to reliable, secure, and maintainable software.
• Participate in code reviews, use feedback to improve code quality, and gradually develop the ability to review other engineers' work.
• Investigate bugs and production incidents, identify root causes, and implement fixes supported by appropriate testing.
• Work with relational databases, including Aurora PostgreSQL, and learn practices for data modelling, SQL queries, and schema changes.
• Contribute to software hosted on AWS, including Lambda-based and containerised services, object storage, and other managed cloud services.
• Support data-intensive applications that process substantial volumes of financial and index information.
• Use CI/CD pipelines and development tools to build, test, and deploy software safely.
• Learn and apply observability, logging, monitoring, and quality controls used to operate production systems.
• Collaborate with engineers, product colleagues, and other stakeholders to understand requirements and deliver useful solutions.
• Take part in design discussions and learn how technical options and trade-offs are evaluated.
• Develop an understanding of financial indices and how the team's software supports customers.
• Improve engineering skills through practical assignments, feedback, pairing, and knowledge sharing.

Required Skills

• A foundation in software development gained through professional work, internships, graduate programmes, university projects, open-source contributions, or substantial personal projects.
