Role overview: Our clientis seeking a Satellite C&DH; System Engineer to support and/or design, integrate, verify, and support the onboard command, control and data management functions for current and nextgeneration remote sensing & communications satellite programs.

The role will own the C&DH; functional architecture, drive tradestudies, and may provide technical authority throughout the spacecraft lifecycle.

Tasks summary: Architecture Concept & Requirements Translate missionlevel requirements into C&DH; functional and nonfunctional specifications.

Produce System Requirements, Interface Control (ICDs), and Description documents.

Perform requirement management and maintain bidirectional traceability throughout the project lifecycle.

Collaborate with cybersecurity to embed resilience and security by design, ECU.

Design & Development Lead detailed design of onboard processors, databuses (Space

Wire, MIL1553, CAN, Ethernet), memory subsystems, and I/O interfaces.

Support software architecture: command sequencing, telemetry packetization, healthmonitoring, services, faultdetectionisolationrecovery (FDIR).

Support Satellite Reference Database development and validation Cross

Functional Coordination, Stakeholder & Program Interaction Communicate technical status, risk assessments and tradestudy results to senior management and/or customers or partners.

Work with FSW teams to define RTOS, APIs, task scheduling, realtime operating system configuration, services usage.

Define uplink command formatting, downlink telemetry packet structures, and groundsegment datahandling interfaces (missioncontrol servers, dataarchiving pipelines).

Coordinate with the TT&C;/PDT engineering and Ground Segment ICDs to ensure endtoend data integrity.

Support B&P; (Phase 0 & pre-phase A).

Integration & Verification (IVV) Develop verification plans, test matrices, and validation procedures for unit, subsystem, and spacecraft level C&DH; tests.

Execute functional tests,



busprotocol compliance, SIL and HIL campaigns.

Manage anomaly investigations, rootcause analysis, and correctiveaction implementation.

Technical Leadership & Mentorship Mentor, guide junior engineers and interns.

Act as technical liaison with customers, partners and external vendors Act as Continuous Improvement stakeholder Contribute to our client''s knowledgebase, process enhancements, and standards.

Configuration, Documentation & Standards Management Author and maintain C&DH; standards (bus protocols, dataformat conventions, redundancy policies).

Ensure all artefacts, analysis and documentations are version controlled in PLM environment.

Support design reviews (SRR, PDR, CDR, MRR/TRRetc.).

Support Technology Road
