【Who we are】 At Aillio, we create innovative low-energy coffee roasters for homes and small businesses, with one mission - to make roasting accessible to all coffee afficionados around the globe. We are an international company with a European-style work culture and employees from all over the world. Over the past few years we've built up a global following within the coffee industry, and are now poised to expand into new market segments. Designed in Denmark. Made in Taiwan. For the love of coffee. 【About the role】 We are looking for a Firmware Engineer to expand our embedded engineering capacity, bridging physical roaster hardware with our digital ecosystem. Operating from our Bangkok office, you will write robust code, bring up enhanced PCB prototypes, and refine real-time control systems. You will collaborate closely with another Firmware Engineer as well as our electrical, mechanical and software engineering teams to ensure high product reliability. 【Your key responsibilities】 1. Embedded Development & Control Systems (60%) Design and optimize real-time C/C++ firmware for ARM Cortex-M microcontrollers. Implement and calibrate drivers for ADC, PWM, I2C, SPI, UART, and thermal sensors to enable high-precision data capture, in collaboration with Electrical Engineers. Design efficient firmware architectures that minimize latency and ensure ultra-reliable thermal safety. 2. Integration & Safety Testing (40%) Develop robust communication protocols (USB/Bluetooth/Serial) to sync roaster telemetry seamlessly with web / cloud apps. Define hardware-to-software API contracts with web/desktop teams and maintain Git version control releases. Troubleshoot physical circuits and firmware using oscilloscopes, logic analyzers, and JTAG/SWD debuggers. Conduct code reviews, implement fail-safe procedures, and fix hardware edge-case bugs to maintain bulletproof reliability. Work closely with mechanical, electrical, and software engineers to bring new roaster hardware concepts from prototype to production, or resolve any product issues. 【Your qualifications】 3-5 years in embedded systems and firmware development. C/C++ proficiency for embedded processors. Experience or understanding of firmware design tools and languages. Understanding of basic testing, coding, and debugging procedures. Business-level English communication and excellent interpersonal communication skills. Robust analytical and problem-solving skills.

Here's how to pick the right one and stand out in your application.
144.883Jobs

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
