Scored from the posting itself — how clearly the role is described, how much it says about pay and benefits, and how recently it was listed. Not a judgement of Customer.io as an employer.

What you need

  • Deep experience with distributed systems and large-scale backend architecture
  • Strong instincts around reliability, observability, and fault tolerance
  • Comfort reasoning about performance, capacity, and trade-offs at scale
  • Significant experience (typically 10+ years) building scalable, distributed systems in Go (or similar statically typed languages)
  • Deep experience with databases - relational (MySQL, Postgres) and non-relational (DynamoDB, BigTable)
  • Comfort working in cloud-native environments (AWS, GCP)

Nice to have

  • Experience with event-driven systems, message queues, or data pipelines is a plus
  • A collaborative mindset — you raise the team around you

What you get

  • Starting salary for this role is $150,000 - $200,000 USD depending on experience
  • 100% coverage of medical, dental, vision, mental health, and supplemental insurance premiums for you and your family
  • 16 weeks paid parental leave
  • Unlimited PTO
  • Stipends for remote work and wellness
  • Professional development budget

Worth weighing

  • No specific mention of the technology stack beyond Go and databases
  • The role requires significant experience, which may limit opportunities for less experienced candidates
  • Participation in an on-call rotation could imply potential for high-pressure situations
