Explore Backend Engineer, Core Experience jobs and discover a pivotal role at the heart of user-facing digital products. Professionals in this specialization focus on building the foundational server-side logic, data storage, and application programming interfaces (APIs) that power the core functionalities of an application. Unlike roles centered on infrastructure or pure data engineering, Core Experience engineers directly enable the features users interact with daily. Their work is critical in translating product vision into a robust, scalable, and performant technical reality, ensuring that the core user journey—be it streaming media, processing transactions, or managing content—is seamless and reliable. Typical responsibilities for a Backend Engineer in Core Experience are comprehensive and demand a high degree of ownership. They design, develop, and maintain backend services and microservices, prioritizing low latency and high availability to serve a global user base. A key part of the role involves architecting and defining data models and API contracts that serve various client applications, such as web and mobile apps, requiring close collaboration with frontend and full-stack engineers. These professionals are responsible for the entire lifecycle of their services, including writing clean, tested code, setting up monitoring and alerting, participating in on-call rotations, and continuously iterating to improve system performance and architecture. They leverage data and A/B testing to inform decisions and drive product quality. The common skill set and requirements for these jobs are both technical and collaborative. Proficiency in one or more backend languages like Java, Python, Go, or C# is standard, coupled with a strong grasp of data structures, algorithms, and distributed systems principles. Experience with cloud platforms (AWS, GCP, Azure), containerization (Docker, Kubernetes), and databases (SQL and NoSQL) is highly valued. Crucially, successful candidates demonstrate a mindset geared towards building for scale, reliability, and observability, using tools for logging, metrics, and continuous integration/deployment. Beyond technical prowess, soft skills are essential: the ability to work cross-functionally with product and design teams, a proactive approach to problem-solving, and a commitment to shared goals. For engineers passionate about creating the invisible engine that drives exceptional user experiences, Backend Engineer, Core Experience jobs offer a challenging and impactful career path at the intersection of technology and product.
