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.
Requirements:
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 career growth in a high-impact technical environment.
• Opportunities for publishing research and contributing to open-source communities.
