This is a senior advisory role at the heart of how we create value for our clients — translating complex analytical work into strategic guidance that directly shapes our clients' investment decisions and growth trajectories.  You are a trusted advisor first and foremost — someone who builds genuine partnerships with senior client stakeholders, earns a seat at the table through deep expertise, and brings the intellectual curiosity and commercial instinct to identify where Gain Theory can make a meaningful difference.  You will bring 12+ years of experience in marketing effectiveness, analytics, or a related consulting discipline.  <h2>What you’ll be doing:</h2> <ul> <li data-leveltext="" data-font="Symbol" data-listid="14" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="1" data-aria-level="1">Acting as a Strategic Advisor to Senior Clients: You'll be the primary consultative voice for your clients — proactively shaping how they think about marketing investment, effectiveness measurement, and growth.
