Operating on product integration with the main e-mail platform providers such Google and Microsoft, is an interesting challenge with significant technical complexity, especially when considering the scale of our traffic and our security guarantees.
Our standards around security, quality, and service availability can only be the highest, but at the same time we foster psychological safety, as we are comfortable with the unknowns and love to experiment to find the right solution, which get things done and keep the eyes on results.
We use data to validate our decisions, measuring our progress and success. Data informs our decision making, our goals, and our roadmap. We are sure you will love joining us if you share our focus on outcomes rather than outputs and leverage factual evidence to justify your arguments and influence the direction of the team.

We will consider experience working with data and infrastructure at scale as a bonus. If you are not sure that you exactly fit all the above criteria, please do get in touch anyway. We are always willing to speak to great candidates even if you do not feel you meet every criteria listed!
