Flexibility is reshaping the energy industry, and our client is developing an innovative digital platform that helps customers unlock the value of their flexible energy assets. With a clear product vision and proven commercial potential, we are seeking a Senior Engineer to play a key role in building the platform and establishing the foundations of a new digital business.

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.

Accountabilities:

• Lead the engineering delivery of a prototype, transforming it into a secure, scalable, and production-ready platform.

• Design, build, and deploy cloud-native solutions using modern development, DevOps, and AI-assisted engineering tools.

• Define and implement technical architecture, development standards, CI/CD pipelines, testing strategies, security controls, and operational processes.

• 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, TypeScript/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 DevOps practices, CI/CD pipelines, automated testing, security, and modern software engineering principles.

• Experience working in fast-paced, evolving environments where priorities can change quickly.

• Proactive, pragmatic, and solution-focused mindset with a passion for building innovative products.

• Excellent communication and stakeholder management skills, with the ability to collaborate effectively across technical and non-technical teams.
