Backend Engineer

Backend Engineer (Node.js / AWS)
Remote - Ireland / Northern Ireland Only
€50,000 - €55,000

I'm working with an early-stage Irish company in the climate tech space, already live with customers and now pushing hard to scale their platform.

They sit on a huge volume of real-world energy data - and are now starting to layer in AI to unlock it.

We're talking:

• Natural language queries over complex datasets
• AI-driven insights for customers
• Longer term - using AI to break down and understand energy usage patterns at source

This isn't theory or "AI strategy decks" - it's being built into a live product.

The role
You'll come in as a dedicated Backend Engineer, taking ownership of how the platform is built, scaled, and run.

You'll be:

• Building and scaling Node.js services
• Working closely with AWS and production environments
• Moving the platform from manual → automated
• Designing systems around onboarding, access, and multi-tenant use
• Playing a key role in how AI features are integrated into the backend

Tech Stack

• Node.js
• AWS
• REST APIs / Microservices
• CI/CD and DevOps (deployments, production)

Who this suits
This isn't a big tech, narrowly defined role.

It's for someone who:

• Has worked in a startup, scale-up, or small team
• Is used to figuring things out without layers of process
• Enjoys ownership - not just tickets
• Can move fast, but still cares about building things properly

Why it's worth a look

• Proper ownership from day one
• Real product, real customers, real impact
• AI being applied in a meaningful way
• Small, collaborative team - no silos
• Clear growth as the company scales

If you're at that point where you want more ownership, more impact, and to actually build something that's going somewhere - this is a good one to look at. Apply today.
