• Supporting a strong engineering culture focused on quality, automation, and continuous improvement

What you’ll bring

• Proven experience as a Senior Software Engineer in a SaaS or product-led environment

• Strong backend capability in C# / .NET

• Deep experience with modern frontend development, ideally React

• Experience building and operating in cloud-based environments

• A strong advocate for automated testing, DevSecOps, and CI/CD practices

• Experience working within Agile frameworks (Scrum, Kanban, or similar)

• Ability to influence technically and culturally — mentoring others and raising engineering standards

What you can expect from us: 

• Structured onboarding, induction, ongoing training and transparent performance driven professional development 

• Rewarding salary packages including lucrative incentive schemes for all 

• Continuous L&D (both internal and externally) 

• Great tech kit

• Hybrid working with a great office space to collaborate - including a gym and roof top terrace!
