Where the headcount is going

DepartmentOpen
Engineering12

Customer Success1

Hiring is engineering-led: 12 of 14 roles sit in Engineering, spread across platform, transport, abuse, developer tools and core backend, while sales and customer success have one role each.

Who they need

Seniority: 8 senior, 2 mid, 4 not stated.

Skills named most: AWS, TypeScript, Node.js, Postgres, queues, Go, Terraform, Datadog, APIs, email infrastructure, SPF, DKIM

Locations: Postings give Americas (8) and Europe (6) as locations; all 14 roles are marked remote, and no country is stated.

How to use this

If you're applying: Each of the six engineering role families (Platform, Security Platform, Trust & Safety, MTA, Developer Tools, Backend) has one opening in the Americas and one in Europe. Pick the family that matches your background and check that posting's own requirements before applying. For example, the MTA roles ask for SMTP, MTAs and DNS. The Americas Platform Engineer role asks for 8+ years. The Platform and Backend roles list AWS CDK and Terraform.

If you're selling or recruiting: Seven of 14 roles opened in the last 30 days, against 2 in the prior 30 days, and none closed; 12 of the 14 are in Engineering. A call makes most sense for the Platform, Trust & Safety and MTA hiring managers. The single Technical Account Executive role (Americas, 160,000 to 220,000 USD OTE) is the only sales opening. That posting says it will help build an early, repeatable sales motion with enterprise deals in scope.
