Hi, I'm Brian, Senior Director of Engineering at Customer.io. We're looking for experienced engineers who want to own a channel end to end — from the infrastructure that delivers billions of messages reliably, to the product surfaces our customers use to build, send, and analyze their campaigns.
Responsibilities
- Build and evolve the frontend experiences customers use to create, preview, and analyze campaigns — editors, configuration, and analytics dashboards
- Design and scale backend systems that process high volumes of messages and events: queue management, retry logic, rate limiting, and real-time event pipelines
- Build automated systems that respond intelligently to feedback signals from external providers — classification, suppression, throttling, and health scoring
- Partner with in-house domain experts to turn their knowledge into automated tooling — you bring the systems skills, they bring the email depth
- Instrument and monitor channel health end to end: signal detection, anomaly alerting, and observability
- Own problems end to end — from architecture and schema design to testing, deployment, and monitoring
- Share knowledge and raise the bar through 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
