Role overview
Customer.io is looking for experienced backend engineers to design, build, and evolve distributed systems that power automated communication at massive scale for over 9,000 companies. The role involves using Go, React, Ember, and AI to help customers send smarter, more relevant messages using real-time behavioral data. The company values ownership, product taste, and a healthy skepticism for "the way things are done," seeking engineers who can move fast in ambiguity and balance best practices with forward motion.
Responsibilities
- Design and build distributed systems in Go that help customers send timely, relevant messages at scale
- Collaborate across teams to debug issues and deliver reliable solutions
- Own problems end to end - from architecture and schema design to testing, deployment, and monitoring
- Participate in an on-call rotation as required, supporting the reliability of the systems you build
- Share knowledge and raise the bar through sharing your progress publicly with short videos, thoughtful writing, and mentorship
- Use AI agents to make multi-file changes by scoping the work, writing the prompt, and verifying the output
Requirements
- 7+ years of experience building scalable, distributed systems in Go (or similar statically typed languages)
- Comfort working in cloud-native environments (AWS, GCP)
- Familiarity with relational databases (we use MySQL) and an understanding of performance tradeoffs
- Experience with observability tooling and operating production systems
- A bias for action over perfection, and pride in owning technical decisions
Benefits
- 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
- A professional development budget
Additional details
- Starting salary for this role is $150,000 - $200,000 USD (or equivalent in local currency) depending on experience and subject to market rate adjustment.

- The company believes in empathy, transparency, responsibility, and a little awkwardness.
