• State management experience (ideally Redux.NET)
  
• Workflow/state machine experience (ideally Stateless)
  
• Comfortable reading/debugging C++ when issues cross boundaries
  
• Experience in complex systems (device integration, multi-service environments)
  

• 
  
• Stronger C++ beyond debugging
  
• Docker / self-hosted deployments
  
• Device comms: MQTT, USB/Serial, CAN
  
• Regulated development exposure (e.g. IEC 62304 / ISO 13485), testing/traceability
  

Hybrid: 4 days onsite (Limerick) — Not negotiable.

Contract: 6 months, extension likely if delivery stays on track.

Interview process: typically 1‑2 stages (screen + technical).

• Strong proficiency in .NET frameworks and C#
  
• Minimum 10 years’ experience in embedded systems
  
• System integration
