Senior Software Engineer, Systems 

As a Senior Systems Engineer at Aerospike, you will play a pivotal role in advancing our high-performance, low-latency platform by developing core systems software with a strong emphasis on performance, reliability, and efficiency. Experience with kernel modules or filesystems is a plus, though not a core focus of this role. You will collaborate with project managers, performance engineers, and quality engineers to align development with business needs and ensure quality.

Responsibilities

• Design and implement systems-level software, especially in areas related to networking, low-level I/O, and hardware interfaces.
• Develop high-performance, low-latency code for interacting with storage and network hardware.
• Debug and optimize OS-level issues across Linux-based environments.
• Ensure system quality through rigorous testing and benchmarking.
• Work with storage hardware to optimize performance.
• Participate in pair programming to improve code quality and knowledge sharing.

Minimum Qualifications

• Fluent in C with deep understanding of low-level programming and memory management.
• Strong understanding of OS internals – threading, concurrency, memory management, and I/O subsystems.
• 5+ years of experience in systems-level software development, such as networking, kernel, drivers, RTOS, embedded, or firmware.
• Experience shipping and deploying performance-critical systems in production environments.
• Proficiency in at least one other language: C#, Go, Java, Python, Rust, etc.
• Self-motivated problem solver – you know when to execute, when to ask for help, and how to drive projects to completion.

Preferred Qualifications

• Experience with large distributed systems software internals, such as Lustre or Ceph.
• Experience with pair programming or technical collaboration.
• Knowledge of the CAP theorem and/or distributed consensus protocols (Paxos, Raft, etc.).
• Familiarity with low-level performance optimization techniques for high-throughput data processing.
• Knowledge of ACID, consistency models, database internals, and indexing techniques.
• Experience with filesystems or Linux kernel development or tuning.
• Familiarity with PCIe, NVMe, DMA, RDMA, epoll, io_uring, or other low-level interfaces.
