Ready to shape the future of digital experiences
Want to lead the design and delivery of scalable, cloud-first applications that make a real difference to people's lives?
Excited by the challenge of modernising legacy systems while driving engineering excellence across Agile teams?
As our Lead Software Engineer, you'll play a pivotal role in evolving StepChange's digital capability, leading the design and delivery of robust, scalable, and high-quality software solutions. Acting as the technical authority for our NextJS-based web channels hosted on AWS, you'll drive front-end architecture decisions, build reusable components, and champion modern engineering practices that support our cloud-first strategy.
Working within a collaborative Agile environment, you'll combine hands-on development with technical leadership, helping to shape our engineering standards while delivering exceptional digital experiences for the clients who rely on our services every day.
What will you be doing?
As the technical lead for our front-end engineering capability, you'll define the standards, patterns, and practices that underpin the development of secure, scalable, and high-performing digital products. You'll provide architectural leadership across our TypeScript, React, and NextJS ecosystem, ensuring consistency, maintainability, and quality across our software landscape.
Remaining hands-on, you'll design, build, and maintain cloud-native applications using AWS technologies including Lambda, API Gateway, RDS, and Cognito. You'll develop reusable React components and shared libraries, contribute high-quality code, and help establish modern engineering approaches through CI/CD, automated testing, GitHub Actions, DevSecOps, and infrastructure-as-code practices.
