Principal Engineer / Technical Executive Type

This is a remote position.

Our client is looking for a Principal Engineer / Technical Executive to take full ownership of their technical ecosystem — from architecture decisions to hands-on execution across the entire stack. They operate in a high-growth tech environment, having rapidly evolved their product capabilities and infrastructure over recent years while pushing forward in AI-driven innovation.

This is not a traditional leadership role. They need someone who builds, ships, fixes, and scales — all in real time. The ideal candidate combines the strategic thinking of a CTO with the execution speed of a senior engineer who still loves writing code daily.

• Deliver end-to-end features across frontend, backend, database, workflows, and AI systems without relying on handoffs
  
• Make and implement key architectural decisions including system design, data structures, caching, and infrastructure setup
  
• Own production systems, diagnosing and resolving issues across servers, APIs, queues, and databases
  
• Lead AI integration initiatives, from experimentation to production-ready deployment
  
• Build and optimize data pipelines, model inference systems, and GPU-based workflows
  
• Design and maintain payment systems, subscription logic, and financial workflows
  
• Develop across all layers including UI components, APIs, testing, and deployment scripts
  
• Set engineering standards through high-quality code, testing, and documentation
  
• Support and mentor engineers across different areas of the stack
  

• 8+ years of hands-on software engineering experience building production systems
  
• Strong full-stack expertise including frontend, backend, databases, and infrastructure
  
• Proven experience integrating AI/ML models into live production environments
  
• Experience building or managing systems that handle financial transactions
  
• Deep understanding of system reliability, debugging, and performance optimization
  
• Experience scaling systems under real user traffic and growth conditions
  
• Ability to move quickly across multiple layers of a system without dependency on specialists
  

• Advanced experience with modern JavaScript frameworks and backend technologies
  
• Strong knowledge of database design and optimization
  
• Experience with infrastructure management, including Linux environments and networking
  
• Familiarity with AI/ML frameworks and model deployment strategies
  
• Ability to evaluate tradeoffs and make pragmatic technical decisions
  
• Strong ownership mindset and problem-solving approach
