Staff Software Engineer – Full Stack, .NET, API

Role Overview

• We're embarking on an engineering transformation with a key focus across full stack full cycle experience including: .NET, AWS and AI powered services.
• Together we will build tomorrow’s bank today, using world-leading engineering, technology, and innovation.
• This is high-impact, high-complexity engineering at its core, shaping how businesses enter and interact with the bank from day one.
• As a Staff Software Engineer, you don’t just contribute, you lead from the front with full-cycle ownership: investigating problems, designing solutions, building, testing, running, and continuously improving critical platforms.
• Grounded in .NET backend engineering with a full-stack mindset, you operate at scale while driving strategic direction, uplifting engineering standards, and mentoring those around you.
• This is a team pushing boundaries, leveraging cutting-edge cloud services, evolving ways of working, and harnessing AI-powered agents and platforms to simplify complexity and accelerate outcomes.

Requirements

• Act as a technical SME and engineering leader, shaping long-term architecture and platform strategy while remaining deeply hands-on in building scalable, cloud-native solutions using .NET/.NET Core, C#, and AWS
• Design, build, and optimise backend systems (APIs, microservices, data access layers, event-driven services) with a strong focus on performance, resilience, and clean architecture patterns
• Drive end-to-end solution delivery across the full stack, with primary depth in backend engineering and sufficient front-end capability (React, Next.js, TypeScript) to deliver cohesive user experiences
• Lead platform architecture evolution, influencing microservices design, event-driven integrations, and cloud-native deployment patterns while setting engineering standards and best practices
• Champion high-quality engineering through CI/CD (GitHub Actions, Artifactory), automated testing (TDD/BDD), observability (CloudWatch, Grafana, Splunk), and DevSecOps practices
• Collaborate closely with stakeholders to translate business requirements into scalable technical solutions, contributing to design decisions and driving measurable business value
• Continuously innovate and improve engineering workflows through automation (Python, PowerShell), deep troubleshooting, and optimisation of cloud infrastructure and delivery pipelines
• Apply an AI-first engineering mindset, leveraging AI-assisted development tools, cloud AI services, and intelligent automation to accelerate delivery and enhance system capabilities
• Develop and scale AI-enabled solutions, including LLM integrations and emerging agent-based workflows, while mentoring engineers and uplifting team capability in modern engineering and AI practice.
