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.

• 
  
• 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.

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.

• 
  
• 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.

• 
  
• 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. xcfaprz
