Role Purpose

As Senior Software Engineer, you will be accountable for the design, development, deployment and maintenance of the software solutions that meet the needs of our business and our customers. This is a hands-on engineering role: your impact is measured through the quality, reliability and timeliness of the software you deliver, and through the technical standard you set for the engineers around you.

You will work closely with product, project, DevOps and QA colleagues, aligning your work to delivery timescales and escalating risks and issues to the Engineering Manager as needed. You will provide technical expertise across design, development and system integration, coach associate and mid-level engineers, and support the embedding of AI-assisted development tools into daily practice.

• Contribute to estimation, sprint planning and scheduling in line with project commitments and SLAs.
• Support the technical release process and sprint retrospectives, driving continuous improvement in how the team works.
• Contribute to architectural and design decisions for your area, making well-reasoned trade-offs and documenting them clearly.
• Review the code of others and act on review feedback, upholding agreed coding standards, patterns and best practice.
• Investigate and resolve production and technical incidents affecting your area, carrying out root-cause analysis and follow-up improvements.
• Coach and mentor associate and mid-level engineers, advising on the correct procedures, policies and documentation requirements across projects.
• Ensure the software you deliver meets the required standards for privacy, security, compliance and regulation.
• Share knowledge across the team through code and architecture review, knowledge shares and continuous learning.
• Undertake any additional duties as reasonably required.

Skills, Knowledge & Experience

• Significant commercial software engineering experience, demonstratable track record of designing, building and maintaining production software at a senior level.
• Extensive full-stack development skills: front-end (JavaScript/TypeScript frameworks) and back-end (dotnet).
• Experience delivering low-latency, API-driven web services and responsive, cross-browser web applications.
• Experience of relational database design and development (SQL Server) and of cloud hosting and deployment (Azure).
• Able to make informed decisions and to demonstrate and communicate priorities across multifaceted projects while managing competing responsibilities.
• Able to communicate clearly, both verbal and written, with technical and non-technical audiences, presenting proposals and solutions, and to take end-to-end ownership of technical work.
• Experience mentoring and advising junior and mid-level engineers in best practice standards.
