The Company

MAS Zengrange (NZ) Limited (MASZ) designs and manufactures sophisticated, high-quality electronic engineering products for international clients and is proudly based in Wellington. Our team thrives on innovation, precision, and delivering world-class solutions.

The Role

We are looking for a Hardware Design Engineer who thrives on starting with requirements and creating complete solutions from the ground up. This role is not about configuring or reusing existing reference designs — we need someone who can architect, design, and deliver original hardware platforms from first principles.

You will be working on analogue interfaces, custom power supply circuits, and microcontroller systems, with a strong emphasis on battery-powered devices. Some experience in RF design is an advantage. You’ll take ownership across the full development cycle, from schematic to prototype validation, working as part of a structured and collaborative engineering team.

Your day-to-day work will include:

• Taking a set of requirements and translating them into a complete hardware architecture, without relying on pre-packaged designs.

• Developing circuits at component level — analogue, digital, and power systems — from concept through to validated design.

• Designing and validating custom SMPS and power supply circuits tailored to unique applications.

• Selecting and integrating microcontrollers (STM32/ARM) into bespoke systems.

• Applying disciplined design practices to ensure compliance and performance.

• Taking designs through schematic capture, PCB layout (Altium), prototype bring-up, and verification.

• Collaborating with colleagues to refine designs, improve processes, and ensure products can be reliably manufactured.

Skills and Experience

We are seeking someone with:

• 8+ years hands-on hardware design experience, with depth in one or more of the following:
  - Battery power & SMPS
  - RF circuits
  - Safety-critical energy/firing circuits

• Demonstrated system-level design and architecture ownership, end-to-end.

• Strong EMC/E3 grounding (shielding, filtering, zoning, stack-up) and mixed-signal layout best practices.

• Proven design-for-ruggedisation experience.

• Proficiency in Altium PCB CAD and confidence with oscilloscopes, power analysers, VNAs, and spectrum/network analysers.

• Ability to pass required security checks.

Nice to have:

• Functional safety product experience or adjacent safety-critical systems.

• Familiarity with IEC 61508 process and safety-case development.

• Exposure to common defence standards for planning/qualification.

Key Technical Focus Areas

• ARM processor integration (STM32/ARM Cortex)

• SMPS design (from scratch, not just integration)

• Analogue circuit design (original development)

• Power supply design and validation

• RF design (advantageous)

• PCB CAD and Altium

Why Join Us?

We offer an innovative work environment where your expertise will directly impact the development of safety-critical systems. You’ll have the opportunity to work alongside talented engineers and be a key contributor to projects that set industry standards.
