This is an exciting opportunity for someone who thrives in a start-up-style environment, enjoys solving complex challenges, and is passionate about creating products from the ground up.

Leverage AI-powered development tools to accelerate delivery while maintaining high levels of quality, reliability, and maintainability.

Deliver integrations with CRM platforms, public data services, pricing engines, and future partner ecosystems. Rapidly convert product concepts into working software, enabling continuous testing, learning, and iteration. Support the development of the future engineering function, technical roadmap, and operating model.

Skills:

Strong hands-on experience with React, Type Script/JavaScript, APIs, Azure, and cloud-native application architectures. Proven track record of delivering products from concept, prototype, or MVP through to live production environments. Strong understanding of Dev Ops practices, CI/CD pipelines, automated testing, security, and modern software engineering principles.
