Job Description

Job Purpose:
Our client is seeking a skilled and hands-on Hardware Design Engineer with embedded software support experience to join their agile R&D team. In this role, you'll be involved in the full product lifecycle -- from concept through to production -- designing custom hardware solutions and contributing to embedded development for smart, connected products used across a range of industries. This is an exciting opportunity for an engineer who enjoys creating reliable, high-performance systems and thrives in a hands-on, collaborative environment where both hardware and software intersect.
Key Responsibilities:

• Design, test, and refine electronic circuits and printed circuit boards (PCBs) for telemetry and IoT applications.
• Work on multi-layer board designs, ensuring performance, manufacturability, and compliance with product requirements.
• Contribute to low-level software development, assisting in firmware programming and embedded integration.
• Collaborate closely with software developers, testers, and product stakeholders to align hardware with broader system requirements.
• Take part in prototype testing, hardware debugging, and performance tuning.
• Support integration of devices with backend systems via communication protocols like sockets and REST APIs.
• Operate within a Linux-based engineering environment -- this is a hardware-centric role, but an appreciation for software and scripting is essential.
• Maintain clear documentation and ensure alignment with project goals and deadlines.

Required Skills & Experience:

• Proven experience in hardware design, especially mixed-signal (analog/digital) circuits.
• Strong skills in PCB layout using tools such as KiCAD, Seetrax, or similar.
• Familiarity with microcontrollers like Atmel (ARM Cortex-M0/M4) or ESP32.
• Hands-on exposure to embedded programming -- whether in C, Python, or Dart -- and the ability to assist in debugging software-hardware interactions.
• Understanding of communication protocols used in IoT systems (e.g., serial, TCP/IP, REST).
• Confident working on Linux-based systems -- this is a must.
• Good communication skills and the ability to work with cross-functional technical teams.
• Ability to take initiative and contribute to both structured projects and fast-moving prototypes.

Bonus Experience (Advantageous but not essential):

• Exposure to RF design, wireless communication technologies (e.g. WiFi, ISM bands).
• Experience with development platforms like Arduino, Raspberry Pi, or similar.
• Familiarity with manufacturing processes, DFM principles, and hardware testing tools like oscilloscopes and spectrum analyzers.
• Mobile or Flutter development experience.
