  • Experience with modern front-end tooling and build systems (e.g., Vite, Webpack) and state management libraries.
  • Experience with CI/CD tools (e.g., GitHub Actions), IaC (e.g., Terraform), and cloud platforms (Azure/AWS).
  • Leverage modern AI tools (e.g. GitHub Copilot, Claude Code, etc.) to improve productivity where appropriate.
  • Good problem-solving skills and understanding of scalable system design.
  • Nice to Have

  • Basic awareness of AI/LLM concepts or experience consuming AI APIs (e.g. simple integrations).
  • Familiarity with tools or platforms from providers like Anthropic.
  • Experience in developing, building, and deploying financial services grade applications and platforms.
  • Knowledge of core Azure services (Azure Functions, Azure API Management, Azure Service Bus, Azure Monitor, Application Insights, Azure Front Door, Azure CDN).
