Join to apply for the Principal Electronics Design Engineer role at Spectrum Control
Description:
In this role, you’ll own the full hardware development lifecycle—from requirements capture to circuit design, simulation, and product integration. You'll combine analogue and digital expertise with system-level thinking to create robust, certifiable solutions that operate in the harshest airborne environments.
Main responsibilities:
* Act as Design Authority for an airborne electronics product.
* Design and simulate analogue and mixed-signal circuits, including filtering, amplification, and power regulation.
* Use LTSpice (or equivalent) to simulate and verify circuit performance across conditions.
* Develop digital systems with FPGAs, SoCs, and high-speed serial interfaces.
* Produce schematics using Altium Designer and support PCB layout integration.
* Work with cross-functional teams—RF, software, mechanical—to ensure cohesive system development.
* Support system integration, bench testing, and troubleshooting of new designs.
* Contribute to and lead design reviews, documentation, and configuration management.
* Engage with system engineering activities, converting requirements into verified design solutions.
* Contribute to DO-254 / DO-160 certification activities and documentation.
Requirements:
* BEng/BSc in Electronic Engineering (or related discipline).
* 8+ years practical design experience in aerospace, defence, or high-reliability embedded systems.
* Strong background in analogue and mixed-signal circuit design for airborne or harsh environments.
* Proven experience with LTSpice, PSpice, or equivalent simulation tools.
* Working knowledge of digital logic, FPGA-based systems, and VHDL (Altera or Xilinx environments).
* Competence in serial interfaces such as RS-422, RS-485, SPI, I2C, and MLVDS.
* Experience with multi-layer PCB design, component selection for aerospace, and high-reliability design principles.
* Experience with hardware integration, commissioning, and troubleshooting at both board and system level.
* Clear understanding of system engineering principles, traceability, and configuration management.
Highly desirable:
* Familiarity with DO-254, DO-160, or equivalent airborne certification standards is a strong advantage.
* Knowledge of STANAG 3910, MIL-STD-1553, or other avionics data bus standards.
* Experience working in certified aerospace environments or on flight hardware projects.
Security Clearance:
* You must be eligible for full security clearance.
