Squarespace is looking for a Senior Software Engineer to join the Async Platforms team within the Building Blocks Platform Engineering group. The Async Platforms team provides Squarespace Engineers with scalable, reliable, secure, and flexible platform solutions for event streaming, job orchestration, and batch processing. The team is charting the path for migrations of custom legacy tooling and setting the standards for new open-source patterns to be adopted at scale. The processes we support are critical to the daily operation of Squarespace. We work with product, platform, and infrastructure teams across Squarespace to ensure we are building the right solutions. As a Senior Engineer on the team, you will lead complex migrations and support internal customers as Squarespace continues to grow. This is an opportunity to set the path and patterns to support the continued growth and scaling of the company as a whole. You will report to the Engineering Manager of the Async Platforms team in our NYC office. This is a hybrid opportunity with three days in the office per week.
