Senior Backend Engineer - Mobile

-THIS POSITION IS REMOTE-

We are building a category-defining platform that brings structure, credibility, and scale to a space that has long lacked all three.

• Implement secure and reliable network communication using REST and real-time channels (WebSockets, Firebase where applicable).
• Participate in architecture and design discussions to ensure mobile requirements are represented in microservices and Azure deployments.
• Build and maintain CI/CD pipelines for mobile builds, automated testing, and release processes to App Store and internal distribution.
• Work to create and run automated and manual tests; drive improvements in code quality through code reviews, unit and integration testing.
• Monitor mobile app performance, crash analytics, and user metrics; triage, debug, and resolve production issues.
• Ensure security, privacy, and compliance requirements are met (including HIPAA considerations when applicable).
• Share knowledge across the team and contribute to the continuous improvement of development practices and documentation.

Qualifications

• Strong understanding of cloud platforms, especially Microsoft Azure, and experience integrating mobile apps with cloud-hosted services.
• Hands-on experience working with microservices architectures; familiarity with Golang-based services.
• Experience integrating with event-driven systems and message brokers (Kafka/RabbitMQ/NATS).
• Solid knowledge of networking patterns for mobile apps, including REST APIs and real-time protocols (WebSockets) preferred.
• Proven track record of delivering production-grade apps to the App Store and supporting CI/CD workflows preferred.
• Strong debugging and performance optimization skills for mobile platforms preferred.
• Excellent communication and collaboration skills; experience working in cross-functional agile teams.
