Job Description

Junior Power Supply Design Engineer

Location: Dublin, Ireland (Hybrid / On-site)

The Role

Our client is looking for a Junior Power Supply Design Engineer to join their growing engineering team working on the design and development of AC/DC and DC/DC power supplies. This is an excellent opportunity for an early-career engineer to gain hands-on experience across the full power-electronics development lifecycle, supported by senior engineers and technical mentors.

You will contribute to the design, simulation, prototyping, and testing of efficient, reliable power solutions used in a range of industrial, medical, automotive, or consumer applications.

Key Responsibilities

• Support the design and development of AC/DC and DC/DC power supplies
• Assist with schematic capture, component selection, and basic magnetics design
• Perform circuit simulation using tools such as SPICE, LTspice, or PLECS
• Support PCB layout reviews in collaboration with layout engineers
• Help with prototype bring-up, testing, and debugging in the lab
• Carry out electrical measurements including efficiency, thermal, EMI, and transient testing
• Assist with documentation, test reports, and design reviews
• Work closely with senior engineers to improve design robustness, efficiency, and reliability
• Comply with relevant safety and regulatory standards (e.g. IEC, UL, CE)

Required Skills & Experience

• Degree in Electrical / Electronic Engineering or a related discipline
• Basic understanding of power electronics fundamentals (SMPS topologies, MOSFETs, diodes, magnetics)
• Familiarity with AC/DC or DC/DC converter concepts
• Exposure to simulation tools (SPICE-based tools preferred)
• Basic lab experience with oscilloscopes, power analysers, and electronic loads
• Willingness to learn and develop within a hands-on engineering environment
• Good communication skills and a collaborative mindset

Desirable (Not Essential)

• Internship, placement year, or thesis focused on power electronics or power supplies
• Exposure to EMI/EMC testing or thermal design
• Familiarity with PCB design tools (Altium, OrCAD, KiCad, etc.)
• Knowledge of wide-bandgap devices (SiC or GaN)

What’s On Offer

• Competitive graduate / junior-level salary
• Structured training and mentorship from experienced power-electronics engineers
• Hands-on exposure to real-world power supply designs
• Clear progression path into Power Electronics Design Engineer roles
