Job summary

Infinite Orbits is seeking a DHS Architect to define, design, and validate the onboard data handling architecture for GEO missions. You will specify functional and performance requirements for DHS, interfacing with software and avionics teams, and ensure full integration and verification through AIT.

The role involves coordinating with AIT for TM/TC validation campaigns, developing FDIR strategies, and reviewing supplier deliverables to ensure end-to-end TM/TC data flows are validated in

Qualifications

• Master's degree in Aerospace Engineering, Avionics, Embedded Electronics, or related field.
• 5+ years of professional experience in satellite avionics or onboard data systems.
• Deep understanding of ECSS-E-ST-70-41 (PUS), CCSDS TM/TC protocols, and avionics redundancy concepts.
• Proven experience testing DHS at unit and system level during AIT campaigns.
• Familiarity with SCOS-2000, EGS-CC, or equivalent checkout systems.
• Demonstrated ability to lead technical reviews, produce interface documentation, and support AIT test phases.
• Clear written and verbal communication skills in English for technical documentation and collaboration.

Responsibilities

• Define onboard DHS architecture, including central OBC, mass memory, TM/TC interfaces, and data buses (RS-422, Ethernet, CAN).
• Specify redundancy logic and autonomous switching mechanisms; maintain functional ICDs with onboard and external systems.
• Develop FDIR strategies and implement software monitoring capabilities for DHS.
• Coordinate with AIT teams to define and review DHS functional test procedures, TM/TC validation campaigns using EGSE/CCS, and interface verification (electrical, software, protocol).
• Support development and automation of test scripts for PUS service verification; lead DHS-related test readiness reviews and resolve anomalies during integration.
• Review supplier deliverables, test reports, and integration plans for DHS equipment.
• Validate end-to-end TM/TC data flows in simulations, hardware-in-the-loop setups, and the final spacecraft configuration.
• Interface with Ground Segment teams to validate SCOS MIBs and operational TM/TC logic.
