As a Lead Software Engineer within the eCommerce Platform Delivery team, you will provide leadership and technical stewardship across a squad within the Booking Assurance Mission. Your role will involve guiding the squad towards technical excellence, fostering a culture of continuous improvement, and driving high performance across all aspects of software development.

Working closely with Technical Product Owner, Agile Delivery Manager and Principal Software Engineer, you will ensure engineering standards are upheld, guide complex technical solutions, and align strategy, approach, and principles within the squad. By championing best practices, modern architectures, and innovation, you will accelerate the delivery of customer-facing features, improve platform resilience, and ensure the platform remains robust, scalable, and future-ready.

What you’ll be doing

• Take accountability for executing the technical direction within the squad - ensuring engineering outcomes support the Mission’s defined technical vision and meet expectations for performance, security, and scalability.
• Strong expertise in .NET internals and architecture - including CLR, garbage collection, async/await, multithreading, thread safety, ASP.NET
• Core, dependency injection, EF Core optimisation, and performance tuning to build scalable, high-performance distributed systems.
• Experience applying Domain-Driven Design (DDD) principles and event-driven patterns - designing maintainable services with clear bounded contexts, secure integrations, and reliable communication across cloud-native applications.
• Work in partnership with the Technical Product Owner - defining outcomes, priorities, and scope while maintaining architectural integrity and long-term technical sustainability.
• Lead the design and implementation of solutions within the squad, ensuring alignment with established Mission architecture.
• Champion data integrity, performance, and operational resilience - ensuring all squad‑owned components are designed and implemented in alignment with Mission‑level architectural patterns.
• Collaborate closely with the Agile Delivery Lead and cross-functional partners - aligning technical direction, refining scope, and managing dependencies that impact squad delivery.
• Own the delivery of key product features - ensuring they meet functional requirements as well as performance, security, and availability standards.
• Ensure the quality of code produced within the squad - upholding engineering best practices, coding standards, and platform-aligned patterns.
• Lead and contribute to code reviews - providing constructive, actionable feedback to elevate engineering quality and develop team capability.
• Use engineering metrics and feedback loops to monitor squad performance - identifying improvement opportunities and supporting the evolution of a high-performing engineering squad.
• Mentor and guide engineers within the squad - supporting technical growth, skill development, and fostering a culture of continuous learning and improvement.
• Stay informed on relevant industry trends and emerging technologies - applying insights to strengthen engineering practices and enhance the squad’s technical capability.
  

What you’ll bring to the team

• Ability to execute squad‑level technical direction and architectural decisions - linking these to measurable outcomes including feature performance, system reliability, and customer impact.
• Experience using engineering measures such as DORA metrics, release frequency, incident response, and recovery times - applying these insights to drive continuous delivery improvements within the squad.
• Proven expertise in cloud and commerce technologies - including AWS, APIs, mobile platforms, and event-driven architecture (EDA) relevant to the squad’s product area.
• Extensive experience in observability practices - leveraging metrics, telemetry using OpenTelemetry, alerts, and logs to ensure the squad’s systems are reliable, performant, and easy to diagnose.
• Proven ability to embed robust security and compliance controls - working closely with Security Architects and InfoSec teams to ensure alignment with organisational standards and regulatory requirements.
• A strong understanding of data platforms and integration patterns - contributing to the modernisation and optimisation of systems while maintaining reliability and performance expectations.
• Experience designing and implementing event‑driven architectures (EDA) - supporting real‑time data flows and enhancing responsiveness within the squad’s services.
• Strong knowledge of infrastructure and networking principles - with experience designing and maintaining secure, high-performance components within distributed systems.
• Strong experience in CI/CD, automated testing, and DevSecOps practices - ensuring high-quality, reliable software releases from the squad.
• Ability to coordinate and lead the squad effectively - managing dependencies, supporting delivery flow, and enabling consistent, high‑quality execution.
• Proven ability to adopt innovative technologies and encourage platform reuse - ensuring the squad delivers solutions aligned with organisational engineering standards.

• Experience working within large‑scale eCommerce or high‑transaction environments - applying this background to strengthen the squad’s design, performance, and scalability considerations.
