Rock‐Solid Reliability: Analyze metrics, identify latency or failover gaps, and deliver code‐level optimizations to keep every request fast and reliable.
Minimum Qualifications
Bachelor’s degree or above in Computer Science, Engineering, or a related field.
5+ years of back‐end development experience, building large‐scale, high‐throughput services.
Proficient in Java, Go, Python, or similar languages, with strong software design and system‐thinking skills.
Experience collaborating with product, platform, and security teams and the ability to explain complex ideas clearly.
Preferred Qualifications
3+ years designing and operating distributed, low‐latency systems (API gateway, cache, etc.) or security‐focused development.
Experience using data to identify performance or reliability bottlenecks and delivering targeted, code‐level improvements.
Thrives in a fast‐paced environment, takes ownership, and iterates based on feedback.
