A note about AI/Agentic Coding… At Hoodie Analytics, we are transitioning to using LLMs for more and more of our software development - from planning changes/features, adding code and unit tests, to reviewing PRs. Any candidate must be keen to work with AI tools in order to dramatically improve their efficiency/throughput. We are not ‘married’ to any particular system, although currently we all use Cursor AI with Cursor Pro subscriptions
