Job summary

Azora is building high-bandwidth space-ground networks linking space terminals, optical ground stations, and customer delivery points. You will own data, telemetry, and control flow across hybrid links with weather-dependent optical paths, covering routing, ARQ, DTN, and security considerations.

Responsibilities include designing ground segments, site diversity, and scheduling across satellite passes, with ICDs and requirements flowing to software, FPGA, and ground teams.

Qualifications

• BS/MS in Electrical Engineering, Computer Science, or related field.
• 7+ years in network architecture or space communications, with 2+ years on space programs.
• Deep knowledge of networking fundamentals and high-latency/lossy links.
• Experience with space link protocols (CCSDS) or equivalent stacks.
• Clear architecture documentation, ICDs, and requirements writing.

Responsibilities

• Architect the end-to-end space-to-ground network, including link-layer protocols and DTN considerations.
• Define protocol stacks for optical links over fading channels and ARQ strategies.
• Design site-diversity, handover, and network availability across ground stations.
• Develop scheduling and resource allocation across satellite passes and customer demand.
• Specify ground segment routing, VPNs, encryption, QoS, and cloud delivery interfaces.
• Define security architecture and key management for secure telemetry/command paths.
• Produce ICDs and requirements for software, FPGA, and ground systems teams.

Job description

Define the end-to-end network architecture connecting Azora's space terminals, optical ground stations, and customer delivery points. You will own how data, telemetry, and control flow across a hybrid space-ground network with intermittent, weather-dependent optical links – covering everything from link-layer protocols and ARQ schemes to ground network topology, routing, scheduling, and security.

Responsibilities

• Architect the end-to-end network: space-to-ground optical links, inter-site terrestrial backhaul, network operations center (NOC) integration, and customer data delivery.
• Define protocol stacks for optical links operating over fading atmospheric channels, including framing, FEC/interleaving strategy at the network layer, ARQ, and delay/disruption-tolerant networking (DTN) where appropriate.
• Design site-diversity and handover strategies that exploit multiple ground stations to maximize network availability under cloud cover.
• Develop network-level scheduling and resource allocation across satellite passes, ground stations, and customer demand.
• Specify ground segment IT/network infrastructure: routing, VPNs/encryption, QoS, monitoring, and integration with cloud delivery (AWS/Azure ground-station-style interfaces).
• Define security architecture across the network, including key management and encrypted command/telemetry paths.
• Produce ICDs and requirements that flow down to software, FPGA, and ground systems teams; support trade studies and customer technical engagements.

Required Qualifications

• BS/MS in Electrical Engineering, Computer Science, or related field.
• 7+ years in network architecture or space communications systems engineering, with at least 2 years on space or satellite programs.
• Deep knowledge of networking fundamentals: TCP/IP, routing, transport protocols over high-latency/lossy links, and performance-enhancing techniques.
• Experience with space link protocols (CCSDS suite – AOS/USLP, COP-1, CFDP – or equivalent proprietary stacks).
• Demonstrated ability to write clear architecture documents, ICDs, and requirements.

Preferred

• Direct experience with optical space-to-ground or inter-satellite links and their availability/fading characteristics.
• Familiarity with DTN (Bundle Protocol), QUIC, or custom reliable transport over intermittent links.
• Experience designing ground station networks, teleports, or satellite operations infrastructure.
• Working knowledge of crypto/key management for space systems (e.g., CCSDS SDLS) and relevant security accreditation processes.

Location

This is an onsite/hybrid role based in Tempe, AZ or the Bay Area, CA – hardware work that’s hard to do remotely. Some travel expected for field deployment and vendor/manufacturing visits.

Benefits:

• Generous equity
• Competitive healthcare (including options for vision and dental)
• 401(k)
• Unlimited PTO

About this Company

Azora is building high-bandwidth communications infrastructure for environments where fiber can’t reach. This work spans LEO spacecraft constellations, lunar exploration missions, GEO satcom, deployable optical ground for defense, and data centers both on- and off-world. To enable rapid global proliferation Azora is developing compact and modular optical terminals small enough to deploy from a backpack, and space terminals that support high speed optical links from LEO out to the Moon.
