Associate Software Engineer (C#/.NET)

Role Overview

This is a graduate-level opportunity within Brokerage Technology to help build and maintain the back-end services and APIs that power Brokerage Pricing. Working alongside senior engineers, you will contribute .NET C# code on a cloud-based distributed architecture on AWS, learn to automate deployments through Infrastructure as Code, and make day-to-day use of AI-assisted development tools. You will collaborate with Business Analysts, QA engineers and Project Managers to turn business requirements into reliable software, and grow your skills across the stack as part of a modernising tech landscape.

Role Responsibilities

• Contribute to the design, development and maintenance of back-end services and APIs in .NET C# on a cloud-based distributed architecture, under the guidance of senior engineers.
• Write clean, well-tested code, with a focus on unit testing and consistent code quality.
• Help implement and maintain Infrastructure as Code using AWS CDK (Python preferred) to deploy and manage cloud resources.
• Make effective, responsible use of AI coding assistants to accelerate development, review and documentation tasks.
• Collaborate with Business Analysts, QA engineers and Project Managers to turn business requirements into working software.
• Participate in agile ceremonies and adopt an agile mindset.
• Investigate and help resolve issues promptly, escalating where appropriate to minimise disruption to business operations.
• Support the modernisation and simplification of the tech landscape.
• Keep documentation of code, processes and system configurations clear and up to date.
• Actively seek feedback and invest in learning across .NET, AWS and applied AI to grow into a well-rounded engineer.

Experience / Competences

Essential

• A degree in Computer Science, Software Engineering, Mathematics or a closely related STEM discipline is required; a Master’s degree is strongly preferred.
• Solid foundations in object-oriented programming, data structures and algorithms, demonstrated through academic work, internships, placements or personal projects.
• Working knowledge of a modern back-end language such as .NET C#, Java or similar, and a willingness to focus on .NET C#.
• Understanding of unit testing principles and the value of automated testing.
• Familiarity with cloud concepts, ideally AWS, and an interest in Infrastructure as Code (for example AWS CDK with Python).
• Comfortable using Git for version control.
• Clear written and verbal communication and an ability to collaborate effectively in a team.
• Curious, detail-oriented and able to stay focused when tasks get complex.

Desired

• Exposure to AI or machine learning through academic projects, coursework or dissertations, for example working with LLMs, Generative AI or classical ML techniques.
• Hands-on use of AI coding assistants (for example GitHub Copilot, Amazon Q Developer or similar).
• Awareness of AWS AI services such as Bedrock.
• Exposure to microservices architectures and API design.
• Experience with containerisation tools such as Docker.
• Familiarity with relational and/or NoSQL databases, and with ORMs such as Entity Framework.
