Associate Director @ Opus Recruitment Solutions | Shaping the Future of Tech firms across UK (JVM - Java, Scala & Kotlin)

I’ve partnered with a modern, eco-conscious energy company that’s shaking up the UK market. They supply gas and electricity to homes nationwide, with a strong focus on affordability, sustainability, and customer-first service. Think green energy—without the big energy baggage.

Customers can choose from a range of renewable energy options, giving them the power to decide how their homes are fuelled. It’s clean, flexible, and future-focused.

Following a series of major successes—including two large acquisitions—they’re now scaling rapidly. They’re currently looking for a Full-Stack Kotlin Engineer to help rebuild their contact centre technology, fully integrated with Amazon Connect.

This isn’t just another engineering role—you’ll be joining a team at the heart of their AI innovation efforts, working with cutting-edge tools and building brand-new features that directly impact the customer experience.

Their current stack includes Kotlin for backend microservices, TypeScript on the frontend, and a mix of GCP and AWS for cloud infrastructure. You don’t need to be an expert in everything—if you have solid experience in Kotlin, TypeScript, or Vue.js, you could be a great fit.

What’s on offer:

• 26 days holiday + bank holidays
• Health and wellbeing programmes
• A chance to work on meaningful, forward-thinking tech
