HIKINEX

We are seeking a Satellite Bus System Engineer to design structural, thermal, power distribution, attitude control, propulsion, CD&H, TT&C/PDT, FSW and interface architecture that supports payloads and mission-operations for current and next-generation remote sensing and communications satellites. The role leads the definition, design, integration, verification and on-orbit support of the platform subsystems, ensuring compliance to mission requirements and company best-practice processes.

Architecture Concept & Requirements

• Translate mission‑level requirements (CONOPs, mass, volume, power, envelope, pointing, lifetime, redundancy, reliability…etc.) into system requirements and allocate them to platform subsystems (structures, TCS, EPS, GNC, PROP, C&DH, TT&C/PDT, FSW).

• Develop the Platform Architecture Description Document, Interface Control Documents (ICD) and Design Description.

• Perform requirement management and maintain bidirectional traceability throughout the program life cycle.

Concept Trade & Feasibility

• Lead trade studies for structural approach, thermal control concepts (MLI, heat pipes, radiators…etc.), power generation options (e.g. solar array & battery technologies).

Detailed Design

• Oversee detailed design of all major subsystems (structures, TCS, EPS, PROP, C&DH, C&T, GNC, payload interfaces).

• Conduct failure‑mode‑effects‑analysis (FMEA) in support to FDIR, fault‑tree analysis and reliability & availability predictions.

• Ensure compliance with mission requirement and payload specifics.

• Maintain platform level performance budgets

• Support FSW and Satellite Reference Database developments

Cross‑Functional Coordination, Stakeholder & Program Interaction

• Present technical status, risk analyses, and trade‑study results to senior management.

• Negotiate and maintain ICDs with payload and all platform subsystems.

• Support to DC & RF harness design, Platform and Payload layout.

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

Integration & Verification (IVV)

• Author verification plans, test matrices, and validation procedures for unit, subsystem, and platform level tests.

• Coordinate, supervise or support:

o  Structural vibration, acoustic & shock testing

o TCT & Thermal vacuum testing

o  Power distribution functional test

o  Closed‑loop test on avionic testbed

• Support FSW integration

Technical Leadership & Mentorship

• Mentor, guide, lead a multidisciplinary team of junior or intermediate system engineers & interns

• Act as technical liaison with customers, partners and external vendors

• Act as Continuous Improvement stakeholder

• Contribute to company's knowledge‑base, process enhancements, and standards development.

Configuration, Documentation & Standards Management

• Maintain platform‑wide standards (structural margin, thermal‑control, power‑bus architecture, redundancy philosophy…etc.).

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

• Support design reviews (SRR, PDR, CDR, MRR/TRR…etc.).

• Support Technology Road‑Mapping & Innovation

Launch‑Site, On‑Orbit & Operations Support

• Support launch‑site interface checklists with LVI responsible engineer, pre‑launch checkout procedures, and early‑orbit checkout scripts.

• Provide real‑time platform engineering support during launch, on‑orbit commissioning, anomaly investigations and contingency operations.

• Support SOOH development and associated operator training.
