About The Role

We are developing a high-throughput, real-time production platform and are seeking a talented Backend Engineer. This role offers the opportunity to take ownership of significant components of our system, including backend services and mobile SDKs, with potential for growth into deeper architectural responsibilities.

What You'll Work On

• Develop and maintain Go services essential for core product functionalities, adhering to strict latency and reliability requirements.
• Build and maintain mobile SDKs for Android (Kotlin) and iOS (Swift), exposing core platform capabilities through stable and intuitive APIs.
• Facilitate cross-platform integration using React Native (TypeScript) and Flutter (Dart), ensuring a smooth adoption experience for developers using these frameworks.
• Contribute to the reduction of end-to-end latency across critical paths, both server-side and on-device, through advanced techniques like streaming, intelligent routing, and targeted optimizations.
• Integrate third-party providers seamlessly by creating clean abstractions, simplifying the process of adding or swapping vendors.
• Troubleshoot production issues spanning application logic, mobile clients, infrastructure, networking, and third-party services, with support from senior engineers.
• Deploy and manage services on Kubernetes across multiple cloud environments, focusing on the graceful handling of long-lived workloads.
• Implement system instrumentation, including latency breakdowns, quality metrics, and SLO tracking, to ensure rapid detection of regressions across both backend and SDK surfaces.
• Write Go and mobile code with a focus on robust concurrency management and comprehensive test coverage, including mocks and integration tests.
• Actively participate in code and design reviews, critically examining failure modes, edge cases, and trade-offs beyond just functional correctness.

What We're Looking For

• 2–4 years of backend development experience, with at least one year of production experience in Go, or strong fundamentals in another typed language and a proven ability to quickly learn Go.
• Hands-on experience developing mobile SDKs, with proficiency in native Android (Kotlin) and iOS (Swift) development.
• Working knowledge of cross-platform frameworks, including a foundational understanding of React Native (TypeScript) and Flutter (Dart), sufficient for building and maintaining bindings and debugging integration issues.
• Comfort working across our language stack: TypeScript, Go, Kotlin, Swift, and Dart. While expertise in all is not required, the ability to read, contribute, and learn quickly across them is essential.
• A genuine curiosity for distributed, real-time, or low-latency systems. Prior domain experience is not necessary, but enthusiasm for understanding how these systems function is key.
• Willingness to delve deeper into underlying technologies, including reading infrastructure configurations, networking documentation, or third-party SDK internals when troubleshooting.
• Strong written communication skills, demonstrated through clear design documents, effective problem scoping, and the ability to surface trade-offs early in the development process. This is a highly valued skill for this role.
