Embedded Software Engineer

Since 2000, TrellisWare has been pushing the boundaries of wireless communications - building the advanced algorithms, waveforms, and communications systems that power everything from small form-factor radios to fully integrated defense solutions. It's a team that connects passion with purpose, where the work genuinely matters and no one does it alone.

The Radio Products Team is looking for a Platform Software Porting Engineer to design, develop, and test the porting foundation of our partner radio vendors' Software Defined Radio products. You'll work closely with vendor-specific embedded hardware, software architectures, platform peripheral/interface abstractions, and inter-processor communication - with strong bonus points for experience in software/system security or deep audio, video, and data network processing.

What you'll be doing:

• Designing, developing, and testing software platform execution environments
• Building and maintaining Linux and RTOS-based hardware abstraction layers, including inter-processor and inter-process communication
• Designing and extending hardware-specific software component variants
• Verifying performance with targeted code and running feasibility/performance analysis on new hardware and software runtime environments
• Working with common Linux services and protocols
• Documenting design alternatives and presenting to stakeholders
• Collaborating cross-functionally to measure, debug, and optimize radio system performance

What you'll bring:

• 4+ years developing embedded Linux and/or RTOS-based board support packages
• 2+ years with the Yocto Project
• Strong C/C++ and Python
• Experience with software debugging and lab test equipment
• Object-oriented design, data link layer, device drivers, and ARM-based processors

The kind of background that helps here:

RF Rx/Tx front-end configuration, embedded system security (secure boot, key management, encryption), high-throughput system design (DMA, minimum-copy, overload control), runtime diagnostics and BIT logging, and standard version control and dev tooling. You don't need to tick every box, a solid mix of these plus strong communication skills goes a long way.

Must-haves: EU resident, fluent in at least one European language besides English, and able to travel internationally as needed.
