We are looking for a Senior Systems Software engineer to join a team of highly skilled and motivated engineers who bring low-latency media streaming to the leanest of consumer devices. Our goal is to develop highly optimized QoS and routing algorithms for cloud-based streaming to achieve ultra-low latencies and smooth streaming. Now, are you passionate about driving streaming technology to its edge? Can you design state-of-art algorithms and solve complicated networking and routing issues? Are you interested in QoS, computer network emulation, packet scheduling, network KPIs and congestion control? Then, we are keen to hear from you.

What you’ll be doing:

• Collaborate with data center network/security architects and vendor partners to build the next generation of streaming technology for cloud-based ultra-low-latency applications.

• Research, develop, and innovate network routing and QoS algorithms for secure ultra-low streaming and improve user experience.

• Collaborate with our partners to build the next generation of networking gear optimized for low-latency streaming.

• Use data analytics to measure user experience and develop features to grow our satisfied user base.

• Define, implement, and improve industry-leading KPIs for networking, streaming quality, latency, and stutter.

• Generate networking models that simulate various real-life end-user networks.

What we need to see:

• PhD or Master’s degree or equivalent experience in Computer Science, EE, or a closely related field.

• 8+ years of experience in networking and software development.

• Fluent in L2, L3 networking stacks as well as IP routing, multicast, QoS, and transport layer protocols.

• Hands-on experience with networking protocols and concepts, including BGP, RTP, QUIC, SCTP, TLS, STUN, TURN, and ICE.

• Familiarity with congestion control, buffer bloat, active queue management methods, and concurrent traffic handling.

• Hands-on experience with programming in C++ and Python, socket programming, multi-threaded systems, and real-time media applications.

• Hardworking and self-motivated with excellent analytical and problem-solving skills.

Ways to stand out from the crowd:

• Experience with IPv4/IPv6 routing optimizations, BGP, OSPF/IS-IS, and knowledge of related protocols.

• Experience in working with global ISPs, internet peering, and network performance monitoring.

• Good understanding of multimedia streaming technologies such as WebRTC and WebTransport.

• Knowledge of Software-Defined Networking (SDN), Software-Defined WAN (SD-WAN), or network security protocols.

• Familiar with wireless communications standards such as 802.11a/b/g/n/ac, LTE, and/or 5G as well as experience in modeling multi-protocol networks using NS3, GNS3, EVE-NG, and/or Mininet.

With competitive salaries and a generous benefits package, we are widely considered to be one of the technology world’s most desirable employers. We have some of the most forward-thinking and hardworking people in the world working for us and, due to unprecedented growth, our exclusive engineering teams are rapidly growing. If you're a creative and autonomous engineer with a real passion for technology, we want to hear from you.

Your base salary will be determined based on your location, experience, and the pay of employees in similar positions. The base salary range is 184,000 USD - 287,500 USD.Applications for this job will be accepted at least until February 28, 2026.
