Job Description

Salary: $150,000 - 250,000 per year Requirements:

• We require strong C/C++ programming skills and experience developing high-performance, production-quality software.
• We require a solid understanding of computer networking, including TCP/IP, UDP, Ethernet, routing, switching, and socket programming.
• We require experience designing and implementing network protocols, congestion control, flow control, and error-recovery mechanisms.
• We require strong knowledge of multithreaded programming, concurrency, synchronization, and thread-safe software design.
• We require experience with parallel processing and performance optimization for multicore CPUs.
• We require proficiency in Linux software development, debugging, testing, and performance profiling.
• We require familiarity with data structures, algorithms, and memory management for systems-level software.
• We require experience with Git and modern software development practices.
• We prefer experience with high-speed networking technologies such as 10/25/100/400GbE.
• We prefer knowledge of forward error correction, data compression, packet processing, or distributed systems.
• We prefer familiarity with cloud computing, virtualization, microservices, or container technologies such as Docker or Kubernetes.
• We prefer experience with network performance and debugging tools such as Wireshark, tcpdump, perf, or gdb.
• We value strong analytical, problem-solving, and debugging abilities, along with excellent communication and collaborative skills.
• Applicants should submit a solution package with source code and any README files needed to build, install, test, and use it.
• Candidates should be able to explain and maintain all parts of their submitted code, including code developed with open-source components or AI tools.

• We are seeking engineers to design and implement a fast data transport product for ML/AI infrastructure systems.
• Design and implement a simple, efficient C/C++ program that reliably transfers files between Linux machines on the same or different networks.
• Support both daemon operation and a simple command-line workflow similar to scp, with an architecture that can be adapted for streaming applications.
• Use UDP for data transfer and implement BBR (V3) congestion control in source code rather than enabling the kernels BBR flag.
• Enable transfers without requiring changes to either machines router or firewall configuration; the task assumes SSH is running and port 22 is open on both networks.
• Keep the solution simple and elegant while prioritizing transfer performance, and be prepared to make or explain modifications and improvements.

More:

We are a Silicon Valley stealth startup hiring several engineers. These roles are remote and available either full time, with an annual salary of $150,000–$250,000 and benefits, or part time/contract, at $100–$250 per hour. Before applying, we ask candidates to complete a mini-project to assess fit with the work; it serves as a starting point for related systems development. Candidates may use open-source components or AI tools, but should understand and be able to explain their final code. The requested solution should avoid complicated packages such as QUIC.
