About the job
We're hiring: Software Engineer - Energy Systems
Location: London, UK
Employment Type: Full Time
Annual Salary: £40,000–£50,000 depending on experience
Working Pattern: 5 days in Office
Closing Date: 5pm, 30 June 2026
About Us
At AEON, we design and install solar, battery, offshore and hybrid renewable energy systems across the UK, Maldives and Fiji.
Through this work, we see many of the practical challenges that slow down the adoption and operation of clean energy systems: monitoring assets across multiple sites, maintaining grid stability, coordinating generation and storage, controlling costs and turning large amounts of operational data into useful decisions.
To address these challenges, we are developing our own software platform. The tools we build are used both by our own teams and by the customers we support, creating a close feedback loop between operators, users and developers.
Our goal is simple: make clean energy systems easier to understand, operate and get value from, whether you're a homeowner, a business, an energy operator or a utility.
We are looking for a software engineer to help design and build this platform alongside our electrical, mechanical and operations teams.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What you'll work on
You will help build AEON's energy software and control platform: EOS (Energy Operating System).
The platform is delivered through two closely connected views:
EOS Enterprise, used by operators, engineers and energy managers.
- Whole-island grid management tools to integrate more renewable energy while maintaining grid stability
- Diesel generator monitoring and optimisation to reduce fuel consumption and operational costs
- Energy asset analytics, forecasting, diagnostics and financial tools
Homie, used by homeowners and businesses.
- Tariff insights, reporting and billing tools
- Energy management assistance, recommendations and reminders
- Helping users understand, adopt and get more value from solar, batteries and other renewable energy technologies
Both are built on the same underlying platform and data.
This role sits at the intersection of software, data, control systems and energy infrastructure.
You'll work closely with electrical, mechanical and operations teams, building software to address existing challenges in the operation of energy systems.
What we're looking for
We expect this role to suit someone with 1-5 years of professional software development experience who is looking to take on greater ownership and responsibility.
