Jack is Experimentation Lead at CharlieHR, a role he's held since 2022, having spent over eight years at the company in total. He first joined as a Content Marketer in 2018, spending three and a half years building CharlieHR's content before moving into experimentation, where he now focuses on testing and optimising what actually drives growth. Jack's career began in marketing and copywriting — starting as Marketing Manager at Tailfin, before moving into a Copywriter role at Sigma Sports. He's since returned to Tailfin on a freelance basis as a Brand Consultant, bringing an outside perspective to brand strategy alongside his day-to-day work at CharlieHR. Across every role, Jack has combined sharp copywriting instincts with a curious, test-and-learn mindset — the same approach that now shapes how CharlieHR experiments its way to better marketing results.
