Hardware Engineer

Location: Hutt Valley, Wellington

Employment Type: Permanent, Full Time

Hours: 40 hours per week, Monday to Friday

Salary: $105,000 + Benefits

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 Engineerwho 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.
