SeniorGoBackendEngineer

ABOUT THE ROLE SourceFuse is looking for a Senior Go Backend Engineer to join the team building the execution layer of a telecom-grade data platform. This is a high-impact, technically demanding role where you will own the core streaming and data processing infrastructure — from Kafka-based ingestion through windowed aggregation, KPI computation, and time-series storage. You will work on systems that process millions of data points every 15 minutes, where performance, reliability, and correctness are non-negotiable. The ideal candidate brings deep Go expertise, hands-on Kafka experience in high-throughput environments, and the distributed systems mindset to deliver production-grade pipelines independently — with zero REST API surface. Everything here is event-driven, internal, and pipeline-first. In the first 3–6 months, success means: - Own and deliver high-performance Kafka consumers/producers in Go, meeting throughput and latency requirements - Implement windowed aggregation, state handling, and idempotent writes to TSDB without requiring daily oversight - Build out adapters for DB/API/SFTP ingestion with clean retry and DLQ strategies - Contribute to observability infrastructure and establish profiling baselines - Deliver against project milestones in a fast-paced Silicon Valley startup environment - Integrate smoothly with a cross-functional, globally distributed team (US + Asia time zones) Key Responsibilities - Build high-performance Kafka consumers and producers in Go for a telecom-grade data platform - Implement windowed aggregation and state handling for real-time streaming pipelines - Design and implement retry logic and dead letter queue (DLQ) strategies to ensure data reliability - Ensure idempotent writes to time-series databases (TSDB — cloud-native, e.g. ADX, Snowflake) - Build adapters for DB, API, and SFTP-based data ingestion - Implement dynamic configuration management using CRD watcher patterns - Write production-grade, secure code following per
