Firmware Developer
Summary
The Firmware Developer will design and maintain embedded software for wireless lighting control products using Nordic Semiconductor platforms. The role involves working with BLE, mesh networking, and AI-powered development tools to deliver scalable, secure firmware solutions.
Build the intelligence inside connected devices.
We are looking for an experienced Firmware Developer to join our engineering team and help develop the next generation of Casambi-enabled products.
Your primary focus will be embedded software development for wireless devices built on Nordic Semiconductor platforms. You will work with Bluetooth Low Energy (BLE), mesh networking, device communication protocols, and system-level firmware that powers reliable, secure, and scalable lighting control solutions.
This role is ideal for someone who enjoys working close to hardware while also understanding complete system architectures, from embedded devices to mobile applications, gateways, and cloud services. We're looking for an engineer who is curious, continuously learns new technologies, and actively uses AI-powered tools to improve development efficiency and software quality.
What you'll do
Design, develop, and maintain embedded firmware for wireless products based on Nordic Semiconductor SoCs
Develop software using Nordic SDKs, including nRF Connect SDK and Zephyr-based solutions
Implement and maintain Bluetooth Low Energy (BLE), Bluetooth Mesh, and other wireless communication technologies
Develop and optimize communication protocols between embedded devices, mobile applications, gateways, and cloud services
Participate in architecture, design reviews, code reviews, testing, and debugging activities
Investigate and resolve complex issues across hardware, firmware, wireless communication, and system integrations
Contribute to device provisioning, security, diagnostics, and over-the-air (OTA) firmware update solutions
Collaborate closely with hardware, mobile, cloud, backend, QA, and product teams
Use AI-powered development tools to improve productivity, code quality, troubleshooting, and learning
Participate throughout the entire product lifecycle, from concept and development to deployment, maintenance, and continuous improvement
Contribute to multiple products and technology initiatives as priorities evolve
What we're looking for
Essential
5+ years of professional embedded software or firmware development experience
Strong C/C++ programming skills
Experience developing software for ARM Cortex-M based microcontrollers
Experience with Nordic Semiconductor development platforms and SDKs
Solid understanding of Bluetooth Low Energy (BLE) and wireless communication principles
Experience debugging embedded systems using modern development and test tools
Understanding of RTOS concepts and embedded software architecture
Experience with communication protocols and device interoperability
Strong problem-solving and analytical skills
Ability and willingness to learn new technologies and domains
Experience using AI-assisted development tools to improve productivity and software quality
Strong communication and collaboration skills
Highly appreciated
Experience with nRF Connect SDK, Zephyr RTOS, or Nordic SoftDevice architectures
Experience with Bluetooth Mesh networking
Experience implementing secure boot, device security, and firmware update mechanisms
Experience with Linux-based embedded systems or gateway devices
Experience with automated testing, CI/CD, and firmware release processes
Understanding of RF technologies and wireless performance optimization
Experience bringing products from concept to mass production and customer deployment
Product-oriented mindset and customer focus
Why join us?
You'll work on products that combine embedded systems, wireless communication, cloud connectivity, mobile applications, and real-world customer deployments. This role offers the opportunity to solve challenging technical problems while developing technology used in hundredths of thousands of installations worldwide.
We value engineers who care not only about writing firmware, but also about delivering successful products that solve real customer problems and continue to provide value long after their initial release.
We are looking for product builders, not just firmware developers. Candidates with experience bringing connected products from idea to customer deployment are particularly encouraged to apply.
