Senior Software Engineer - Backend Platform
Overview
We're looking for experienced backend engineers who want to build and own the infrastructure that powers one of the most data-intensive platforms in marketing automation.
Job Description
You'll work on the Platform team, tackling hard distributed systems problems: designing for fault tolerance, scaling services under real production pressure, and building the foundational layers that every other team at Customer.io depends on.
Responsibilities
- - Design and evolve distributed systems in Go to handle billions of daily events and messages and store and index petabytes of data
- - Lead architectural decisions around performance, reliability, and real-time event processing
- - Improve service-to-service communication through better APIs, messaging systems, and event-driven patterns
- - Work across teams to uncover bottlenecks and system issues, and lead initiatives to resolve them for a smoother customer experience
- - Tackle high-throughput challenges across data pipelines, queues, and scheduling infrastructure
- - Able to debug production systems at scale using effective instrumentation, and resolve issues quickly and confidently
- - Share knowledge and raise the bar through sharing your progress publicly with short videos, thoughtful writing, and mentorship
- - Leverage AI tools to prototype, move faster, and make better decisions
Required Skills
- - 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
- - Experience with event-driven systems, message queues, or data pipelines is a plus
- - A collaborative mindset — you raise the team around you
- - 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) - and how to make them fast
- - Comfort working in cloud-native environments (AWS, GCP)
- - Familiarity with APIs, observability, 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
