Senior Electrical Engineer (m/f/x)

At atmio, we're building technology that helps the oil & gas industry drastically cut methane emissions. One of the most powerful levers we have in the fight against climate change. Our gas measurement devices make invisible emissions visible, so operators can act fast.

We are looking for a Senior Electrical Engineer to lead the electronic design of our sensor devices. You will focus on creating robust, ultra-low-power boards capable of operating in demanding industrial environments.

Key Responsibilities 🎯

• Design, test, and iterate on mixed-signal circuits and PCB layouts using KiCad
• Optimize hardware for ultra-low power consumption, battery operation, and industrial environments
• Build, debug, and iterate on prototypes hands-on
• Guide the product through external certifications (EMC, CE, ATEX) and collaborate with suppliers to transition prototypes into mass production
• Mentor junior engineers and actively contribute to shaping our hardware development processes from the ground up
• Take technical ownership of hardware modules from concept to production, working closely and collaboratively with our firmware and mechanical teams

This role is a perfect fit if you... ✨

• Are comfortable working with early-stage prototypes and refining them for reliable mass manufacturing
• Enjoy building hardware processes and lab infrastructure from scratch
• Value balancing technical perfection with economic and timeline constraints
• Want to make a tangible, positive impact on our planet 🌍

Skills & experience you will need 💪

• Proven track record of delivering industrial electronic products from idea to mass production

• Expertise in schematic capture, PCB layout, and mixed-signal design
• Strong knowledge of microcontrollers and communication interfaces (SPI, I2C, UART)
• Hands-on experience with debugging tools (oscilloscopes, logic analyzers), soldering, drilling
• Experience designing battery-operated devices and optimizing power management

Great to have ➕

• Experience with ATEX / Intrinsic Safety (Ex i) design constraints
• Experience with RF/IoT hardware integration (e.g., LoRaWAN, NB-IoT, LTE-M, BLE)
• Familiarity with mechanical CAD design (e.g., Fusion360, SolidWorks) to easily align with mechanical engineers
• Experience with gas measurement devices (methane, ethan, hydrogen)

• Hybrid Working: Work from our hub in Hamburg and from home

• Unlimited Vacation: Take as many holidays as you need — we trust you to recharge when it matters most
• Flexible Working Hours: Work during the hours that align with your peak performance and lifestyle
• Mental Health Matters: Access 1:1 psychologist sessions and workshops through our Bloom partnership
• Professional Growth: Use a dedicated development budget to enhance your skills and career
• Stock Option Plan: Receive virtual stocks as a reward for your trust, effort, and vision alignment
• Unite, Recharge, Celebrate: Join in-person team retreats to connect and have fun
• Explore Germany: Enjoy the Deutschlandticket for flexible public transportation access
