Conduct trade‑studies for modulation schemes, coding, frequency plans, ranging and link budgets.
Produce System Requirements, Interface Control (ICDs), and Description documents.
Perform requirement management and maintain bidirectional traceability throughout the project lifecycle.
Collaborate with cyber‑security to embed resilience and security by design.
Design & Development   Lead detailed design of hardware (TT&C transceiver, RF front‑ends, antenna‑pointing) and software (command sequencer, telemetry parser, health‑monitoring).
Perform link‑budget analysis, RF simulation (e.g., STK, Matlab), and error‑budget budgeting.
Verify compliance with CCSDS, ECSS, ITU, and regulatory standards.
Support Satellite Reference Database development and validation
Cross‑Functional Coordination, Stakeholder & Program Interaction   Present technical status, risk analyses, and trade‑study results to senior management.
Negotiate and maintain ICDs and interface agreements with internal & external suppliers.
Support B&P (Phase 0 & pre-Phase

A).
Integration & Verification (IVV)   Develop test plans, procedures, and verification matrices for unit, subsystem, and spacecraft‑level TT&C tests.
Execute RF link testing, BER, command latency, and telemetry integrity verification.
Manage anomaly investigation, root‑cause analysis, and corrective actions.
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 knowledge‑base, process enhancements, and standards.
Configuration, Documentation & Standards Management   Ensure all artefacts, analysis, software, deliverables and documentations are version controlled in PLM environment.
Support design reviews (SRR, PDR, CDR, MRR/TRR…etc.).
Support Technology Road‑Mapping & Innovation
On‑Orbit & Operations Support   Support launch‑pre‑launch and early‑orbit checkout – validate command uplink, telemetry acquisition, and on‑board software hand‑over.
Provide real‑time C&T support during nominal and contingency operations.
Maintain ground‑segment configuration…
