About the role You will join ZEISS Vision Cares global Disruptive Innovation team to develop embedded firmware and control algorithms for electro-active prescription eyewear. This senior role owns hands-on and product-facing, driving firmware quality, validation and manufacturability readiness while collaborating closely with electronics developers and system owners in Germany. You will Implement and optimize embedded firmware (C/C++) for ARM-based microcontroller systems controlling electro-optical components. Develop and refine control algorithms for precise actuation, sensing, stability and power management (wearable-grade performance). Build internal test platforms, diagnostics and automation tools for device characterization, calibration and regression testing (Python or similar). Create and maintain unit tests, component tests and system-level software tests; support software reliability testing and qualification. Integrate firmware with electronics hardware (bring-up support, debugging, interface validation). Work with cross-functional teams (optics, mechanics, electrochemistry, hardware, manufacturing) to integrate complete systems. Support design transfer to global manufacturing sites, including production test concepts and traceable documentation. Document firmware architecture, design decisions and validation results for long-term product development. Interface with global procurement and suppliers for component-level validation, firmware dependencies and robustness (e.g., MCU/PMIC variants). At least 5 years of experience in embedded firmware development in C/C++ on ARM-based microcontrollers (e.g., STM32, Nordic, Microchip or similar) and Python for automation or testing. Strong understanding of communication protocols such as I2C, SPI and UART; BLE/WiFi experience is a plus. Hands-on experience with hardware prototyping, debugging and system-level testing. Experience with product validation processes, including software reliability testing, qualification, software security protocols and safety integrity considerations. Ability to develop test tools and automation frameworks for device characterization and calibration. Exposure to battery-powered devices, electro-optical systems, wearable electronics or smart eyewear platforms is a strong advantage. Basic understanding of analog electronics and PCB-level integration, enabling effective collaboration with hardware engineers. Experience working with external suppliers, manufacturing partners and distributed global teams; strong English communication skills. Basic familiarity with Android/iOS ecosystems and companion app integration. A builder mindset with high ownership and curiosity, comfortable exploring new device concepts and contributing to disruptive innovation initiatives (e.g., sensor integration, connected device features and future smart eyewear capabilities).

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.
