At Zipline, you'll continue to have career development conversations with your manager to ensure your compensation grows as you advance. Our salary ranges are determined by market, factoring in our revenue and employee size and paying competitively. In higher cost of living markets, we apply 5-10% multipliers on our ranges, depending on the location, to maintain competitive compensation and reflective of the increased expenses our team members face in those areas. While we primarily hire in Canada and the USA, we are a global employer, and all hiring regions will use the same methodology to determine fair and transparent pay. Transparency is key to building trust in our compensation process. To better understand how this range is determined, we encourage you to ask as many questions as you'd like about compensation during the interview process to ensure clarity and confidence.
