Senior Software Engineer

QA Automation Engineer

• Work on the design, development, and deployment of AI-powered automation solutions that enhance and free Hackeronies from the endless stream of routine, manual, splinter-pulling tasks, e.g. writing meeting notes or updating spreadsheets, the ones that feel satisfying to check off simply because they relieve pain, not because they create strategic or transformative value. Once these tasks are automated, human capacity is unlocked to focus on strategic direction, creativity, and edge-case governance.
