High Speed Electronic Design Engineer

MBRYONICS is at the forefront of free space optical communications. Our product portfolio covers a wide range of emerging technologies from photonic integrated circuits to advanced optical systems and embedded software solutions. Our optical communications systems are integrated and deployed in satellite communications systems. The work is exciting and challenging and is at the forefront of the technology domains. As part of our expansion, we are currently looking for a suitably motivated - High-Speed Electronic Design Engineer - to join our group.

• →Design wideband optical signal chain architectures and capture schematics for components including ultra-low-noise Transimpedance Amplifiers (TIAs), high-speed laser/modulator drivers (EAM/Mach-Zehnder), high-sampling-rate ADCs/DACs, and optical phase/bias control circuitry.
• →Define multilayer PCB stackups, route controlled-impedance lines, specify differential microstrip/stripline geometries, balance skew matching, and apply back-drilling to maintain signal propagation integrity into the tens of gigahertz regime.
• →Conduct thorough pre- and post-layout Signal Integrity and Power Integrity analyses—encompassing eye diagrams, jitter decomposition, S-parameter extraction, frequency-domain PDN profiling, and link loss budgets.
• →Develop end-to-end electro-optical noise models, calculate Bit Error Rates , and establish channel link budgets across electro-optical interfaces.
• →Collaborate closely with photonic integrated circuit (PIC) specialists, optical physicists, thermal engineers, and mechanical teams to co-package sensitive RF/optical die and refine board-level interconnects.
• →Validate and characterize high-speed optical transceivers using Bit Error Rate Testers (BERTs), Vector Network Analyzers , spectrum analyzers, and high-bandwidth real-time/sampling oscilloscopes.
• →Mature systems from initial high-speed benchtop prototypes through to space-qualified flight hardware adhering to ECSS/AS9100, MIL-STD, and relevant JEDEC standards.
• →Generate comprehensive technical documentation, including simulation reports, hardware qualification test procedures, interface control documents (ICDs), and design review materials.

• Degree (Bachelor’s or Master’s) in Electronic Engineering, Electrical Engineering, RF/Microwave Engineering, or a related discipline.
• At least 5 years of practical hardware engineering experience, focusing on high-speed digital, RF, or wideband analogue systems.
• Strong expertise in key PCB CAD tools such as Altium Designer, Cadence Allegro/OrCAD, or Mentor Xpedition.
• In-depth understanding of high-speed termination strategies, transmission line theory, return path control, cross-talk reduction, reference plane discontinuities, and via stub resonance.
• Demonstrated background in developing wideband analogue front-ends (including TIAs, differential amplifiers, and high-speed op-amps) and executing SPICE time/frequency-domain simulations.
• Practical, hands-on experience utilizing high-speed and RF test benches.
• Skill in routing high-speed serial links and integrating them alongside primary control buses.

• Proficiency with 3D full-wave electromagnetic and channel modeling suites (such as ANSYS HFSS, Cadence, or Keysight ADS).
• Experience with space-flight electronic equipment, AS9100 quality systems, component derating standards, and radiation-hardening techniques.
• Knowledge of packaging electrical interconnects for photonic integrated circuits (PICs), optical sub-assemblies (OSAs), flip-chip devices, and RF wire bonding.
• Direct experience integrating HDLs (VHDL/Verilog) with FPGA multi-gigabit transceivers (MGTs/GTH/GTY).
• Familiarity using mechanical CAD software (e.g., SolidWorks, Fusion 360) for thermal management of high-power-density RF/optical systems.
