Your mission

The infrastructure processes millions of requests per day and is a mission-critical component of our customers' businesses. As an Engineer Manager, you will be empowering teams responsible for designing, building and running the fronted software which enables users to visually create connectors integrations and automations that can run reliably and at scale.

Our software is used by hundreds of different customers including world-class technology companies.

We’re looking for energetic, charismatic managers with a technical background to support and coach our engineers and help drive technical initiatives that improve our engineering practices. Software Engineers at work in interdisciplinary squad teams arranged around a mission, with clear responsibilities and objectives.

You will be working as part of a friendly, cross-discipline agile team who help each other solve problems on both server and client side. Ideally, you will be an experienced developer and technical leader who has shipped large-scale single page web apps in the past.
