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 - systems that process millions of events per second, orchestrate complex workflows at scale, and keep everything running reliably for thousands of customers worldwide. 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. This isn't just maintenance work - you'll shape the architecture of systems that need to be both highly available and constantly evolving. If you're someone who gets energized by the intersection of scale, reliability, and developer experience - and wants ownership over infrastructure that truly matters - we'd love to talk., You drive technical direction across systems and teams. You move with urgency, build with empathy, and think long-term. You've led large-scale infrastructure initiatives and know what it takes to get them over the line. Engineers with customer focus You think about how infrastructure unlocks customer value. You care about developer experience, system design, and how your work shapes the customer experience. A healthy disregard for "the way things are done" You bring rigor and creativity. Best practices matter, but never more than forward motion. What You'll Do * 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, * Hiring Manager Interview (60 mins) - Talk with one of our hiring managers about your working style and a project you've owned end-to-end, plus a short AI-assisted coding exercise. * System Design Interview (60 mins) - A collaborative system design conversation focused on scaling challenges. * Coding Interview (60 mins) - Pair with one of our engineers for an agentic live coding interview. All final candidates will be asked to complete a background check and employment verifications as part of our pre-employment process.
