    We are seeking a mid‑level RF engineer to support the technical management, production readiness, and lifecycle sustainment of an UT Modem/RF module used for DVB operation within the Telesat Lightspeed LEO network.

    This role is hands‑on but product‑focused—ideal for an engineer who understands RF hardware deeply, but operates comfortably at the intersection of systems engineering, product and program management, manufacturing, test, and sustaining support. You will act as a technical anchor for the UT Modem/RF module as it transitions from development into qualification, volume production, deployment, and long‑term operational support.

    Main Responsibilities

    RF Module Technical Stewardship

  • Serve as a technical owner for an RF module supporting DVB‑S/S2/S2X and/or DVB‑RCS2 operation in a LEO satellite network.
  • Support RF architecture definition and performance budgets (gain, noise figure, linearity, phase noise, spurious emissions).
  • Ensure RF performance compliance across process, voltage, temperature, aging, and environmental corners.
  • Support system‑level trade studies and impact assessments when requirements or operating conditions evolve.

    • Design Review & Engineering Oversight

  • Review and approve RF schematics and PCB layouts produced by internal or external design teams.
  • Ensure adherence to best practices for:
  • RF grounding and isolation
  • EMI/EMC mitigation
  • Shielding and thermal management
  • Mixed‑signal partitioning
  • Participate in formal design and readiness reviews (PDR, CDR, MRR), identifying technical risks and proposing mitigation strategies.

    • Manufacturing & Production Support (Primary Emphasis)

  • Act as the engineering interface to contract manufacturers (CMs), ODMs, and key suppliers.
  • Lead or support DFM/DFT/DFS reviews, with focus on yield, repeatability, and long‑term producibility.
  • Define and maintain:
  • Manufacturing test strategies
  • Acceptance criteria
  • Golden units and correlation plans
  • Support EVT/DVT/PVT builds and production ramp‑up.
  • Analyze production data (yield, fallout, trends) and drive root‑cause analysis and corrective actions.
  • Own or support ECO/ECR processes, ensuring controlled and traceable changes throughout the product lifecycle.

    • Test, Verification & Interoperability

  • Develop, review, and maintain RF, functional, and system‑level test procedures.
  • Support validation and production testing including:
  • EVM / MER
  • ACLR
  • Phase noise
  • Harmonics and spurious emissions
  • DVB waveform compliance
  • Work closely with system and test teams to ensure requirements traceability and verification completeness.
  • Support environmental, thermal, and reliability testing aligned with high‑reliability or aerospace practices.

    • Embedded Control & Firmware Collaboration

  • Support embedded control architectures used to configure and monitor RF hardware.
  • Review and support interfaces such as SPI, I²C, and UART.
  • Collaborate with firmware teams on:
  • Board bring‑up
  • Calibration and compensation routines
  • Telemetry, health monitoring, and diagnostics
  • Ensure embedded control…
