ByteDance's Foundational Technology team is looking to solve critical system challenges by developing high-availability, performant software components and foundational services, with a focus on low-level storage and network domains, including the development of in-house metadata storage engines for ByteDance's ultrascale Kubernetes clusters.
Requirements
- Strong programming skills in C++ or Go in Linux environments, with experience in writing clean, maintainable and testable code.
- Have a solid understanding of CS Fundamentals: basic data structures (lists, queues, stacks, trees, graphs, hash tables) and algorithms (binary search, quick sort, divide and conquer, backtracking), operating system (processes, threads, mutexes, semaphores, deadlock, paging, segmentation, file system), network (OSI models, TCP/UDP, IP addressing, HTTP, DNS).
- Have a basic understanding of distributed systems (e.g. CAP theorem), databases (e.g. relational vs nosql, transaction, isolation levels), and storage systems (e.g. replication, erasure encoding).
- Familiarity with advanced data structures (LSM trees, B+ trees) and algorithms (Paxos, Raft).
- Hands-on or research experience with distributed systems such as HDFS, Colossus, Spanner, Chubby, ZooKeeper, etcd.
- Familiarity with linux system programming (epoll, io uring) and high performance networking (RDMA, DPDK).
Responsibilities
- Assist in designing and developing ultra-performance metadata services, including distributed coordination, locking, key-value storage, and service discovery features.
- Support the creation of automated and disaster-tolerance deployment solutions for virtualized and bare-metal environments.
- Analyze service performance metrics, generate insights, and propose data-driven improvements to enhance reliability and efficiency.
- Participate in technical discussions and documentation efforts, ensuring alignment with team standards and best practices.
Other
- Currently pursuing a PhD degree in Computer Science or related fields in Computer Science, Electrical Engineering, or a related technical field.
- As an international team, we thrive on innovation and collaboration, working with both technical infrastructure teams (compute, storage, databases) and upper-layer business units (advertising, payments, AI) to solve critical system challenges.
- Please state your availability clearly in your resume (Start date, End date).
