Communications Network Engineer
- Study, design, implement, and optimize IP-based networking protocol and communications. + Provide guidance for the upper-layer development using minimalist solutions whenever suitable (TUN, TAP, etc). + Architect and implement L3-L5 layers for next-generation in association with standardized simplex or, more generally, duplex links (ETSI/CCSDS standard families). + Define QoS and services (low-latency, high capacity) to manage routing and traffic prioritization, ensure efficient resource allocation, congestion control. + Perform system level simulations (NS-3 or similar) and profile system performance. + Accelerate time-to-market by leveraging, re-using and configuring existing opensource tools and software solutions over re-creating proven software.
- Lead the development, implementation and deployment of network architectures with an emphasis on operational efficiency and health monitoring. + Monitor network layer behavior including IP packet processing and TT&C data on specific channels, addressing and routing to ensure performance stability and level in accordance with system level requirements. + Monitor transport layer behavior including connection metrics, datagram metrics, throughput, latency, errors, and port usage.
- Develop and maintain Linux kernel network adapters. + Actively participate in cross-functional team meetings, collaborating with other departments to ensure cohesive communication and problem-solving approaches. + Configure system level networking, QoS and traffic prioritization (interference management, optimal bandwidth allocation, concurrent customer management and resource allocation) with additional features such as scheduling, timestamping, TUN client adaptation or telemetry handling.
- Collaborate closely with the L1-L2 team as well as with the FPGA engineers, contributing to seamless integration across all communication layers and cross-layer optimization.
- Actively participate in cross-functional team meetings, adopt problem-solving approaches., As a Communication Systems Network Research Engineer at Spire, you will help shape a cutting-edge network infrastructure for our expanding satellite constellation.
