Halian Technology Limited
Charing Cross, London
£100,000 - 100,000
Requirements
Must:
We are looking for candidates with strong C#/.NET development experience (preferably .NET 8) in production environments. Proficiency in Python, particularly in analytics, data workflows, or system integration contexts, is essential. Experience with Azure services, including Functions, App Services, Batch, and Blob/Table/Queue Storage is necessary, with exposure to ASP.NET Web API and Cosmos DB being a plus. You should have a solid grasp of software engineering fundamentals such as testing strategies, version control (e.g., Git), clean architecture, and CI/CD pipelines. A background in mentoring or technical leadership, with the ability to review code and support team growth, is important. Strong communication skills are required to clearly explain technical topics to both technical and non-technical stakeholders, along with a problem-solving mindset and a keen eye for performance and user experience. We value curiosity about the non-life (general) insurance analytics domain, although you do not need to be an actuary. Experience working with large datasets and real-time analytics pipelines, as well as familiarity with Agile development practices emphasizing flexibility, collaboration, and end-user impact, is also desired.
Responsibilities
As a backend software engineer, you will lead feature development on a high-impact analytics platform, focusing on performance, scalability, and long-term maintainability. You will bridge and optimize the integration between C# (.NET 8) and Python codebases, refactoring and enhancing them as necessary to reduce inefficiencies and improve modularity. You will improve the performance of complex data pipelines and real-time calculation engines, working with large datasets (4GB) to deliver rapid, reliable results. Reviewing code and mentoring peers will be a key part of your role, as you provide feedback and foster skill development within a growing, collaborative team. You will promote engineering excellence by championing best practices in clean code, CI/CD, automated testing, version control, and modern architectural principles (e.g., SOLID). Additionally, you will collaborate cross-functionally with actuaries, analysts, and data scientists to translate technical solutions into real-world insurance value. Exploring and prototyping emerging technologies to enhance platform capabilities or operational efficiency will be part of your contributions towards a positive engineering culture grounded in curiosity, innovation, and continuous improvement.
Description
This is a hybrid working role with two days on-site and three days remote, based in central London. We have a 2-3 stage interview process, with interview slots immediately available. Apply now to be considered.
