Skills and experience

CRITERION

REQUIREMENT

ESSENTIAL / DESIRABLE

Experience

3 to 5 years of experience in OOH media planning, with demonstrated ownership of client campaigns

Essential

Technical skills

Strong working knowledge of audience and measurement tools (Geopath, Nielsen, Google Analytics, or similar); advanced spreadsheet skills; comfort in web-based planning platforms; exposure to campaign evaluation and attribution methodologies

Essential

Industry knowledge

Out-of-home media, retail media networks, ad tech / programmatic

Essential

Behaviours

Operates independently with sound judgment on priorities; confident presenting and defending a recommendation; invests in developing others; brings the builder’s mindset described below to everyday work

Essential

Value alignment

Onescreen hires and develops people with a builder's mindset: curiosity about how things actually work, a habit of pulling the thread past the first explanation to the structural cause, systems thinking that asks "what's the most efficient way to do this" before "how do I do this," and a discomfort with the status quo that shows up as extending the system instead of routing around it. We're services-led today, by design, but our enterprise value depends on proving a scalable platform model — which means every workaround, stale export, or side-doc this role creates or notices is a signal worth surfacing, not a convenience worth keeping quiet. This role is evaluated on the builder's mindset as directly as it's evaluated on its core responsibilities.


What this means for this role:

  • Builds the planning process, not just the plans: when a step is slow, manual, or inconsistent across planners (market selection, cost schedules, proposal build), documents a better way, tests it on live campaigns, and turns it into the team standard.
  • Works as a product partner, not just a product user: brings structured requirements to the Product team based on real campaign needs, pressure-tests new features on live plans, and treats every workaround, stale export, or side-doc as a product gap to close rather than a habit to keep.
  • Shapes client strategy from the data up: uses audience, market, and performance insights to challenge the brief when it doesn’t fit the objective, and brings a point of view on where OOH should play in the client’s broader mix rather than executing the request as given.
  • Connects what they learn across campaigns back into the system: patterns in what works for a vertical, recurring client objections, or vendor gaps feed into planning playbooks, platform improvements, and future recommendations instead of staying in one planner’s head.
