Senior Backend / Product Engineer (Elixir)
Dublin - Hybrid / Remote€90,000 - €110,000 + Equity + Benefits
About the Company
We're working with a fast-growing Irish start-up that has raised over €4M to date and is now scaling its engineering team.
They've built a strong product already in market, leveraging AI & automation heavily and are entering the next phase of growth, with more customers coming on board and a clear roadmap ahead.
It's a small, high-performing team where every engineer has real impact on both the product and the direction of the business.
The Opportunity
This isn't a role where you'll just pick up tickets and disappear into the codebase.
You'll be working closely with the Head of Engineering and wider team to build, shape, and improve a live product, with real ownership from day one.
If you enjoy working in a start-up environment where you can take initiative, contribute to decisions, and see the impact of your work quickly, this is the kind of role that will suit you.
What You'll Be Doing
You'll be building and scaling backend systems that support a real-world product used by customers today.
The role sits somewhere between backend and product engineering, so you'll be involved in everything from developing features and APIs through to thinking about how the product should evolve.
There's a strong emphasis on collaboration, problem-solving, and taking ownership rather than being handed tightly defined tasks.
Tech Stack
Elixir (Phoenix, LiveView)
Open to Ruby on Rails or Python backgrounds

What They're Looking For
Strong backend engineering experience (5+ years ideally)
Solid understanding of databases and data modelling

Actively using AI in your development workflow

Experience with Elixir, Phoenix or LiveView
Exposure to frontend technologies (React or similar)
Experience building or scaling early-stage products
Working Setup
Hybrid working - typically 3 days in the Dublin office but open for the right candidate depending on locality

Collaborative, flat team structure
Package
€90,000 - €110,000 salary (flex depending on experience)
Equity in a growing start-up
30 days annual leave
Pension and healthcare
Why Apply?
This is a great opportunity to join a start-up at the right time - early enough to have real impact, but established enough to have product, funding, and momentum behind it.
If you're looking for more ownership, more product exposure, and a role where your work genuinely matters, it's well worth a conversation.
