Senior Software Engineer - Email Channel
Build and scale end-to-end email channel infrastructure and customer-facing frontend for high-volume messaging. Requires 7+ years in Go, React experience, cloud environments, email deliverability expertise, and full-stack ownership.
About the job
What You'll Do
- Build and evolve the frontend experiences customers use to create, preview, and analyze email campaigns — template editors, sending configuration, deliverability dashboards
- Design and scale the backend systems that power high-volume email sending, including queue management, retry logic, and event processing (bounces, complaints, deferrals)
- Own deliverability-adjacent systems: bounce classification, suppression management, IP/domain reputation monitoring, and feedback loop processing
- Partner with our deliverability team to translate domain expertise into automated tooling — reputation scoring, warm-up schedules, sending throttles
- Instrument and monitor the health of the email channel: inbox placement signals, block detection, ESP feedback, and alerting
- 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
What We're Looking For
- 7+ years of experience building scalable, distributed systems in Go (or similar statically typed languages)
- Experience building product-facing frontend features in React or similar frameworks, with attention to UX quality and polish
- Comfort working in cloud-native environments (AWS, GCP)
- Familiarity with relational databases (MySQL primarily) and an understanding of performance tradeoffs
- Familiarity with high-volume email sending concepts: bounce handling, feedback loops, and delivery event processing
- Working knowledge of email authentication standards — SPF, DKIM, DMARC — and how they affect deliverability
- Comfortable reasoning about sender reputation, IP warm-up, and ISP behavior at scale
- Experience with observability tooling and operating production systems
- Experience building or consuming APIs that handle high-throughput async workloads
- A bias for action over perfection, and pride in owning technical decisions
