Senior Software Engineer - Email Channel

Overview

Job Description

Responsibilities

• - 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

Required Skills

• - 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 (we use 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

• - 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
