Break down complex projects into clear, actionable tasks and drive them through to completion. Mentor and support team members with code reviews, technical guidance, and sharing best practices. Collaborate cross-functionally with product managers, designers, and engineers to deliver impactful features. Continuously improve engineering processes, tools, and practices within an agile environment. What you'll bring: 5–8 years of professional software engineering experience with strong Golang proficiency, ideally in product-driven companies. Solid programming fundamentals, excellent problem-solving skills, and expertise in system design. Deep understanding of concurrency, multi-threading, and distributed computing concepts. Experience building microservice architectures and developing RESTful APIs. Demonstrated analytical and reasoning skills, with the ability to visualize and simplify complex systems. Experience working with high-throughput, low-latency systems is highly desirable. Familiarity with cloud platforms (AWS/GCP), NoSQL databases, big data analytics, or machine learning services is a plus. A growth mindset and a genuine desire to learn, improve, and help build leading-edge backend systems.
