Role Summary: Provide technical leadership for a delivery squad building and operating C#/.NET web services, Angular front-end applications, and event-driven services on Azure Kubernetes Service (AKS). Own the squad's technical direction while line-managing engineers, conducting code reviews, contributing hands-on to complex work, and ensuring the squad delivers reliably and sustainably. Drive adoption of AI-assisted development tools across the squad to accelerate delivery and raise engineering productivity.

Purpose: Provide technical leadership for a delivery squad, owning the squad's technical direction and ensuring delivery of high-quality, secure, and maintainable software solutions across the C#/.NET and Angular stack. This role contributes to the organisation's mission by translating technical direction into effective implementation, embedding build-run ownership, and enabling the squad to balance delivery speed with long-term sustainability. The role combines hands-on technical involvement — including code review, design guidance, and direct contribution to complex areas — with people management, delivery coordination, and team development. A core expectation of this role is driving the adoption of AI-assisted development tools (e.g. GitHub Copilot, Claude) across the squad, setting standards for their effective use, and ensuring AI tooling is embedded in engineering workflows to maximise team productivity.

Key Responsibilities:

• Own the technical direction and design decisions for the squad's C#/.NET web services and Angular front-end applications, ensuring alignment with organisational standards and principles.
• Provide technical leadership and guidance to developers and other engineering disciplines embedded within the squad.
• Conduct regular, thorough code reviews across the full stack, maintaining high standards for quality, security, and consistency while using reviews as a coaching tool.
• Contribute hands-on to critical or complex areas of the codebase — including API design, service integration, event-driven patterns, and front-end architecture — where direct involvement adds the most value.
• Define and evolve service design patterns for event-driven architectures, ensuring reliable messaging, idempotency, and appropriate use of event brokers (e.g. Azure Service Bus, Event Grid).
• Ensure all services deployed to AKS follow agreed standards for containerisation, health checks, resource management, and observability.
• Ensure all software delivered by the squad meets agreed standards for quality, security, performance, reliability, and maintainability.
• Own the operational health, performance, and reliability of squad-owned systems running on AKS.
• Lead and coordinate technical response to production incidents affecting squad-owned systems.
• Ensure operational considerations such as monitoring, resilience, supportability, and recovery are built into solution design from the outset.
• Identify, prioritise, and drive remediation of technical debt and continuous improvement initiatives across the C#, Angular, and infrastructure layers.
• Coordinate technical dependencies with other squads, platform teams, and shared services.
• Partner closely with the Engineering Manager to support delivery planning, prioritisation, and sustainable execution.
• Coordinate with Product Management to ensure technical delivery aligns with product priorities, translating product requirements into technical plans and providing visibility on technical constraints, trade-offs, and opportunities.
• Line-manage engineers within the squad, conducting regular one-to-ones, setting objectives, and providing continuous feedback.
• Coach and mentor developers and senior developers, developing technical capability within the squad across C#/.NET, Angular, Azure, and broader engineering practices.
• Contribute to hiring and onboarding activities, including technical interviews and probation reviews.
• Foster a culture of psychological safety, collaboration, and accountability within the squad.
• Drive adoption of AI-assisted development tools (e.g. GitHub Copilot, Claude) across the squad, defining standards for AI-assisted code generation, code review, test creation, and documentation to maximise team productivity.
• Contribute to the evolution of engineering standards, patterns, and best practices across the wider technology organisation.

Technology Stack:

• Back-end | C#, .NET (Web API / minimal API), Entity Framework
• Front-end | Angular, TypeScript, HTML, CSS/SCSS
• Messaging & Events | Azure Service Bus, Event Grid, event-driven patterns (pub/sub, CQRS)
• Container & Orchestration | Docker, Azure Kubernetes Service (AKS), Helm
• Cloud Platform | Microsoft Azure (App Services, Key Vault, Azure SQL, Storage, Monitor)
• CI/CD | Azure DevOps Pipelines or GitHub Actions
• Observability | Application Insights, Azure Monitor, structured logging
• Source Control | Git

Skills & Competencies:

• Required:
• Advanced software engineering expertise in C#/.NET with the ability to define and lead effective technical solutions across web services and event-driven architectures.
• Solid working knowledge of Angular application development with TypeScript.
• Experience designing and operating event-driven services, including messaging patterns, idempotency, and fault tolerance.
• Practical experience with AKS or Kubernetes in a production environment, including deployment, scaling, and troubleshooting.
• Strong understanding of system architecture, service design, and operational considerations.
• Demonstrated ability to conduct effective, constructive code reviews that raise quality and develop team members.
• Ability to lead technical outcomes through influence and collaboration rather than authority alone.
• Strong analytical and problem-solving skills, particularly in production environments.
• Clear communication skills, able to articulate technical direction and trade-offs to diverse stakeholders.
• Demonstrated ability to coach, mentor, and develop other engineers.
• Experience managing or leading an engineering team, including one-to-ones, objective setting, and performance conversations.
• Experience driving adoption of AI-assisted development tools (e.g. GitHub Copilot, Claude) across a team, including defining standards for AI-assisted code generation, code review, and test creation in C# and Angular workflows.

• Desirable:
• Experience with CQRS and event sourcing patterns.
• Familiarity with infrastructure-as-code (Terraform, Bicep) and GitOps practices.
• Experience with Azure DevOps or GitHub Actions CI/CD pipeline design and maintenance.
• Understanding of agile delivery practices and facilitation techniques.
• Experience contributing to hiring, onboarding, and performance management.
