Senior Full-stack Engineer

Galway (Hybrid) Remote in Ireland considered

Want to build systems that truly matter, not just another dashboard for tracking office coffee consumption?

Our client, a leading technology company, is building a next-generation platform used in law enforcement, finance and intelligence. Think data fusion, serious search, visualisations and smart LLM integration. Real-world impact. Real technical depth. No fluff.

They're looking for a Senior Full-Stack Engineer who can genuinely own systems end-to-end.

What You'll Be Doing

• Build production-grade Python systems (FastAPI or similar)
• Design clean, robust APIs that don't fall over under pressure
• Handle async, streaming, background tasks and real-world performance issues
• Create rich React + TypeScript frontends with complex, data-heavy UIs
• Think about failure modes, scaling and long-term operability
• Ship systems that last, not demo-ware that dies in 3 months

You'll be working on search, analytics, and data-heavy workflows, so if databases, indexing strategies, or high-scale systems excite you you'll be in your element.

What We're Looking For

You're someone who:

• Has strong Python in production
• Is genuinely comfortable across React + TypeScript
• Understands architecture trade-offs (and can explain them)
• Has shipped systems that survived real users
• Can review code written by humans and LLMs (yes, that's part of the job) Doesn't need a 40-page spec to function

Bonus points if you've worked with:

• OpenSearch / Elasticsearch
• ClickHouse or large-scale OLAP systems
• Kubernetes, Docker, and cloud deployments

You don't need to be an SRE. But if a pod breaks, you shouldn't stare at it like it's a philosophical puzzle.

What This Is Not

• Not a pure frontend role
• Not a pure backend role
• Not a "we built a demo once" environment
• Not micromanaged

They want engineers with opinions. Engineers who can say:

"That won't scale."

"That's risky."

"Here's a better way."

And then back it up.

Why This Role Is Interesting

• Serious technical challenges
• Real ownership from day one
• High-trust environment
• Smart, opinionated team
• Hybrid working available
• Salary based on ability, coupled with stock options, so you have skin in the game

You'll build systems that are used in high-stakes environments. That's not something you get to say every day.

If you're a genuine end-to end engineer who enjoys building production systems that live longer than your average SaaS trend, this could be a great move.
