• Work with large-scale financial datasets and contribute to systems that collect, process, validate, and serve data to users.

• Troubleshoot technical issues and contribute to the continuous reliability and improvement of production systems.

• Share technical knowledge, communicate complex concepts clearly to technical and non-technical stakeholders, and contribute to a culture of continuous learning.

• Support and contribute to CI/CD, infrastructure, and observability initiatives where appropriate.

Requirements:

• Strong professional experience designing, developing, testing, and operating production-grade software systems.

• Advanced proficiency in Golang, including experience building backend services and working with concurrent or distributed systems.

• Strong frontend development experience with React and TypeScript, including the ability to build reusable, component-based applications.

• Strong SQL skills and experience working with relational databases such as MariaDB or comparable technologies.

• Solid understanding of clean-code principles, software design practices, and idiomatic Go and TypeScript development.

• Experience with Docker and containerised application deployment.

• Ability to design and maintain performant, scalable, and reliable software systems.

• Strong problem-solving skills and the ability to understand and work effectively within complex technical and business domains.

• Excellent communication skills, with the ability to explain complex technical subjects to both technical and non-technical audiences.

• Ability to take ownership of features and deliver solutions from concept through production.

• Opportunity to contribute to a data-driven platform used by major global organisations and financial institutions.

• Exposure to modern technologies including Go, TypeScript, React, AWS, Docker, SQL, CI/CD, and observability tooling.

• Opportunity to influence technical direction, architecture, engineering standards, and development practices.

• Collaborative environment with a multidisciplinary technology team and opportunities for knowledge sharing.

• Meaningful technical ownership, with responsibility for features from conception through production.

• Opportunities to develop skills in large-scale financial data, distributed systems, cloud technologies, and AI-enabled engineering.

• Please note that the contractor arrangement does not include paid time off or sick pay.
