About the role

Key responsibilities & impact

Design and build low-latency inter-process and inter-host transport in C++, including zero-copy data paths, shared-memory buffers, and lock-free queues
Measure and reduce end-to-end latency and jitter as message volume grows
Ensure transport resilience when processes crash or restart, hosts start out of order, and networks drop or delay packets
Investigate fleet and simulation issues to root cause and fix them in the design
Build pub/sub and RPC messaging APIs with required delivery, ordering, and latency guarantees
Evolve message schemas and the Protocol Buffers-based serialization layer, including schema evolution and compact encodings
Move existing users onto new formats without breaking compatibility
Set technical direction and lead designs spanning several teams
Own the roadmap and release commitments
Collaborate with firmware, product security, simulation, manufacturing, and IT

Requirements

What you’ll need

Bachelor's or Master's degree in computer science, electrical / computer engineering, or equivalent experience
7+ years of experience in software development
Strong modern C++ on Linux, in large codebases with performance-critical paths
Background in transport or networking software, such as messaging systems, network protocols, or communication between distributed systems
Experience building low-latency systems and reducing tail latency using zero-copy, shared memory, lock-free data structures, and cache-aware data layout
Solid systems fundamentals, including concurrency, memory management, process lifecycle, sockets, and the Linux networking stack
Hands-on experience with shared-memory IPC, pub/sub or RPC middleware such as DDS, ROS 2, or iceoryx (bonus)
Experience with serialization frameworks such as Protocol Buffers, nanopb, or FlatBuffers (bonus)
Experience with PTP (IEEE 1588), UDP multicast, MTU and fragmentation behavior, or time-sensitive networking (bonus)
Experience in robotics, automotive, aerospace, or another real-time or safety-relevant domain (bonus)
