We are seeking a highly skilled System Programmer who excels in building low-level, high-performance systems under constrained compute environments. In this role, you will design and optimize realtime voice processing pipelines, architect efficient system-level solutions, and collaborate closely with ML teams to enable cutting-edge voice AI performance. This position requires deep technical ownership, exceptional problem-solving abilities, and a passion for pushing the limits of realtime audio technology.
Key Responsibilities
Architect and implement low-latency, high-performance voice processing systems using C/C++/Rust.
Build and optimize realtime audio streaming pipelines with strict sub-100ms latency requirements.
Develop custom memory management and threading frameworks tailored for voice AI workloads.
Design efficient data structures and algorithms for realtime signal and audio processing.
Integrate and optimize voice model inference using hardware accelerators (GPU/TPU).
Optimize compute resources across CPU, memory, and network layers for intensive streaming workloads.
Build robust failure recovery, fault tolerance, and error-handling mechanisms for production systems.
Partner with ML engineers to integrate voice models into realtime system architectures.
Diagnose complex system-level issues across the entire processing stack.
Research and prototype innovative approaches to performance constraints and edge-compute challenges.
Required Qualifications
Bachelor's/Master's degree in CS, ECE,



or equivalent practical expertise.
3–5 years of hands-on systems programming experience in C/C++ or Rust.
Experience in audio processing, DSP, multimedia, or low-latency application development.
Proven experience delivering high-throughput, low-latency system architectures.
Strong understanding of Linux internals, system calls, kernel-level behavior, and performance tuning.
Proficiency in real-time systems, concurrency models, and multithreaded programming.
Experience working with network programming and realtime streaming protocols (WebRTC, RTP/RTCP).
Solid understanding of memory management, cache optimization, and SIMD/vectorization techniques.
Hands-on experience with GPU programming frameworks (CUDA, OpenCL) or hardware acceleration.
Strong debugging and profiling skills using tools such as gdb, perf, or valgrind.
Ability to take full ownership of complex challenges and independently drive solutions.
Benefits & Perks
Competitive compensation along with meaningful equity.
Delivery-focused work culture with Saturday WFH flexibility.
Food allowance and comprehensive health insurance.
Accelerated learning and mentorship from senior engineering leadership.
Direct influence on system architecture and product decisions.
Opportunity to work with advanced voice AI technology and research initiatives.
Rapid growth opportunities in a high-impact technical environment.
Opportunities for publishing research and contributing to open-source communities.
