Compensation

At Zipline, we're committed to paying our team fairly, transparently, and in a way that supports growth. This role is targeting an annual salary within the United Kingdom of £79,424 to £97,074.

The broad salary ranges reflect the growth someone will experience in the role—from developing skills to reaching expertise within their career level. We've found that hiring team members with the expectation of being accomplished in the role sets them up for success, which for this position on the United Kingdom band is £79,424. Salaries below this point typically reflect someone with potential but still building the necessary skills, while salaries above are for individuals already excelling in the role, with a deep understanding of Zipline's impact on customers, product, and company.

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.
