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 supports both manufacturing test and in‑service operation.

Product Lifecycle & Sustaining Engineering

Provide ongoing engineering support for deployed hardware, including:

Field issues

Performance anomalies

Failure analysis and returns

Manage component lifecycle risks, including obsolescence and second‑source qualification.

Maintain configuration control, technical documentation, and manufacturing records in PLM systems.

Support long‑term product roadmap considerations, including upgrades and end‑of‑life planning

Education and Experience

• B.Sc. in Electrical Engineering or related discipline (M.Sc. preferred).
• 3–6 years of experience supporting RF hardware in production or operational environments.
• Strong understanding of RF components and subsystems (LNAs, mixers, PLLs, PAs, filters).
• Experience reviewing RF schematics and PCB layouts, rather than performing layout work.
• Familiarity with DVB physical‑layer concepts and performance metrics.
• Hands‑on experience supporting test development and automation (e.g., Python/SCPI, LabVIEW).
• Demonstrated experience working with manufacturing partners and supporting production issues.
• Strong documentation, change management, and cross‑team communication skills.

Specialized Knowledge, Skills and Abilities

• Experience with LEO satellite systems or user terminals.
• Exposure to systems engineering practices (requirements decomposition, verification planning).
• Experience working with ODMs or high‑volume CMs.
• Familiarity with embedded Linux, Yocto, or board‑level bring‑up support.
• Exposure to EMI/EMC compliance or aerospace qualification testing.
• Experience sustaining products post‑deployment.
• Experience in working with external vendors and Product Management organization
• Comfortable owning hardware beyond initial design.
• Manufacturing Empathy: Designs and decisions informed by production realities.
• Systems Thinking: Understands how RF modules fit into larger communication systems.
• Execution Focus: Drives issues to closure across organizational boundaries.
• Clear Communicator: Effectively interfaces with RF, systems, firmware, test, and suppliers.

Working Conditions

• This position will be based out of the Ottawa, ON office
• Full-time office or hybrid 4 days office/1 day remote, subject to work needs
• Working conditions are generally comfortable typical of an office environment.
• Combination of lab, manufacturing, and office work.
• On‑site presence required for debug, FA, and production support activities.
• Occasional travel to manufacturing and UT development partners and test facilities (≈10–15%).
• Candidate must be able to obtain relevant security clearance for Canada
