We are seeking an exceptional Senior Software Engineer who combines strong backend expertise in Go (Golang) with good React.js capabilities and, most importantly, a product-builder mindset. This is a high-impact role for an engineer who goes beyond simply implementing requirements. You will identify problems, understand customer needs, shape solutions, and own outcomes end-to-end from technical design and implementation to rollout and iteration. While this is a full-stack position, the primary focus will be on building and evolving our high-throughput Go microservices ecosystem, powering millions of critical daily interactions, while contributing to intuitive React experiences where needed. We are looking for someone who thinks like a builder and acts like an owner, proactively identifying opportunities, challenging assumptions, making pragmatic decisions, and partnering closely with Product, Design, and Engineering to turn ambiguous problems into simple, scalable solutions.
