What we'd like to see from you:

  • Proven backend development expertise, with experience delivering complex, high-scale systems
  • Ability to mentor, guide, and upskill engineers within the team
  • Familiarity with or eagerness to advance in:

o Model Context Protocol for managing context and tool interfaces for agents

o LLM integration patterns including prompt orchestration, multi-agent planning and tool calling

o Retrieval-Augmented Generation (RAG) for dynamic context injection

o Model selection / A/B testing / observability

What will success look like:

  • Delivers high-quality, maintainable code that meets business needs
  • Takes ownership of complex problems end-to-end, from design through deployment
  • Rapidly learns, applies, and advocates for emerging AI-native engineering patterns
  • Raises the bar for technical excellence, system simplicity, and agent-readiness
