Preferred Qualifications: Infrastructure-as-Code experience using AWS CDK, Terraform, CloudFormation, or similar technologies GitLab CI/CD experience OpenTelemetry experience Experience supporting highly available or mission-critical systems Experience mentoring and developing engineers Experience incorporating AI-assisted development tools into engineering workflows

Compensation Salary Ranges by Career Level: Early-career: $95,600 - $147,200 Mid-career: $130,300 - $209,900 Late-career: $154,600 - $242,900

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
