Senior Software Engineer, Systems

Job Description

Aerospike is seeking a Senior Systems Engineer to contribute to its high-performance, low-latency platform. The successful candidate will develop core systems software, focusing on performance, reliability, and efficiency. This role involves collaborating with project managers, performance engineers, and quality engineers to align development with business needs and ensure system quality.Aerospike is the uncontested leader in next-generation, always-on, hyperscale data solutions. Unlike legacy NoSQL systems, their patented Hybrid Memory Architecture unlocks today’s hardware to deliver unimaginable performance and value for the most demanding data workloads—from the edge, to the core, to the cloud.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.

Aerospike offers:

• Opportunity to shape the future of data management.
