About the Role

Our Intelligent Messaging (IM) team is the unified home for all of Attentive’s messaging products. We’re bringing together everything related to messaging — infrastructure, delivery systems, content intelligence, and personalization.

Why? Because we believe the future of marketing communication is intelligent, unified, and channel-agnostic. Whether it’s SMS, email, or the next big channel, marketers should have one powerful system that delivers seamless, data-driven conversations with their customers.

We’re looking for a Software Engineer II who’s excited to help build the future of Attentive’s omni-channel messaging platform. You’ll design and develop the backend systems that enable our customers to deliver communications at massive scale.

This is a hands-on role where you’ll collaborate with engineers across AI, personalization, and product delivery teams to bring new messaging experiences to life. You’ll help unify our messaging stack, strengthen the foundations of our platform, and ensure that new capabilities benefit every channel we support.

This role follows a hybrid schedule, with engineers working from our New York office Tuesday–Thursday each week.

• Build and scale backend services and APIs that power Attentive’s messaging products across SMS, email, and emerging channels
• Work closely with AI and personalization teams to bring intelligent content and automation into the messaging experience
• Design for performance, reliability, and scalability — our systems handle billions of messages, so efficiency matters
• Contribute to architectural decisions and help shape how our unified messaging systems evolve
• Collaborate across product, data, and infrastructure teams to deliver a cohesive omni-channel platform
• Mentor peers, review code, and help drive engineering best practices across the team

• 3+ years of backend development experience using languages like Java, Kotlin, Go, or Python
• Strong understanding of distributed systems and microservices architecture
• Experience with cloud technologies (AWS, GCP, or Azure) and containerization (Docker, Kubernetes)
• Comfortable working with data stores, queues, and streaming systems like PostgreSQL, Redis, and Kafka
• You care about writing clean, maintainable, and well-tested code
• You’re collaborative, curious, and love solving complex system problems
