SR Engineer — SATCOM Networking & Software (C/C++/Python) at MTI Systems. Location Information: USA. We’re building and fielding SATCOM networking capabilities where software, RF realities, and operational constraints collide. If you’ve shipped networking software that had to perform under real link conditions (latency, fade, intermittent connectivity, limited compute) and you can lead others while still getting your hands dirty in code, we want to talk.. What you’ll own. Architect and implement . IP networking over SATCOM. (onboard and ground/gateway), including routing, tunneling, QoS, and security controls.. Build the . simulation → emulation → hardware-in-the-loop. test pipeline to validate performance, resilience, and failure modes before deployment.. Lead technical execution: make design calls, write and review production code, mentor engineers, and drive engineering rigor (docs, test, CI).. Partner with systems/RF teams to translate . link characteristics. (latency/jitter, Doppler, fade, throughput variability) into robust network behavior.. Produce engineering documentation suitable for customer delivery and (where applicable) government compliance.. Must-have. 5+ years building . production networking software. (not just configuring networks): packet processing, sockets, routing/tunneling, performance debugging.. Strong proficiency in . C/C++. and . Python. (systems programming and test automation).. Deep understanding of IP networking: . IPv4/IPv6, TCP/UDP, IPsec/TLS, tunneling (GRE/VXLAN/WireGuard/etc.), MPLS/BGP/OSPF. (as relevant).. Experience designing systems for . high-latency / intermittent / bandwidth-variable. links (SATCOM, RF, cellular, DTN-like environments).. Ability to lead: you’ve owned architecture decisions, driven execution, and raised the bar for peers.  . U.S. Citizenship Required. Nice to have . SATCOM-specific experience: link budgets, ACM/MODCOD, DVB-S2X, gateway/beam constraints, LEO handovers, crosslinks.. Space/data standards or disruption-tolerant patterns: . CCSDS, DTN/BP. , store-and-forward, resilient routing.. Network modeling tools: . ns-3, OMNeT++, OPNET/Riverbed Modeler. , Mininet, containerized emulation labs.. Embedded/edge: . embedded Linux. , constrained compute environments, NIC offloads/DPDK/eBPF (if relevant).. Government programs: RMF, STIGs, FIPS-aligned crypto, COMSEC exposure (as applicable). ​​​​​​​. ​​​​​​​Link16 or other MILSPEC radio experience. Active clearance or ability to obtain one . Why this role. You’ll be the person who ensures the system works not only on a whiteboard, but on real links, with real constraints and you'll get to solve critical problems.
