My client, a clean-tech company, is transforming how the UK manages energy efficiency, with 60,000+ devices already deployed and a fleet that's growing fast.

• Vue.js framework experience (essential - React/Angular background considered but Vue.js strongly preferred)
• Strong Python backend development skills
• Database design and schema modeling experience with high-volume datasets
• JavaScript proficiency
• Project ownership experience - leading medium-sized projects or major components from concept to release
• SaaS product development background preferred

What's on offer:

• Salary up to 70,000 depending on experience + great benefits including:
• 25 days holiday + bank holidays
• 5% pension contribution
• 1500 annual training budget + 12 paid training days

• Exposure to cutting-edge data practices and machine learning concepts

The Role:

Working on the analytics platform, you'll be handling large-scale data processing and building features that directly impact heat network efficiency across the UK. With upcoming government regulations expected to drive significant client growth (from 40% to 60%+ uptake), you'll be scaling critical infrastructure that's making a real difference to carbon efficiency.
