-
Support production testing and field issue resolution.
- Define project plans, scope, milestones, and deliverables for the firmware team.
-
Ensure timely releases with high-quality and well-documented firmware.
Required Qualifications & Skills :
- 5- 8+ years in embedded firmware development.
- Experience in a leadership or principal role preferred.
- Programming Languages : Strong proficiency in C/C++ for embedded systems; exposure to ARM Cortex-M architecture.
- RTOS : Hands-on experience with FreeRTOS or similar RTOS platforms.
- Power Efficiency : Expertise in designing low-power firmware for battery-operated devices.
- Concurrency & IPC : Experience with dual-core processors, inter-core communication, semaphores, and synchronization.
- Low-Level Development : Familiarity with linker files, startup scripts, bootloaders, and system initialization.
- Communication Protocols : Proficient with BLE, NFC, UART, I2C, SPI, and other embedded interfaces.
- Debugging Tools : Skilled in using JTAG, SWD, oscilloscopes, logic analyzers, and other real-time debugging tools.
- Hardware Platforms : Prior experience with Cypress PSoC6 (preferably PSoC63) is highly desirable.
-
Team Skills : Strong communication, documentation, and leadership skills with a proven track record of mentoring engineers.
Senior Embedded Software Engineer
@ Embedd 
What we're looking for
At embedd.it, we power hardware-software integration in embedded devices. We turn fragmented semiconductor chip data into configurable digital twins, then deterministically generate code, tests, and documentation – making integration faster, cheaper, and resilient to supply chain shocks.
We’re looking for a true legend – someone with abstract thinking and deep expertise in low-level software development. You’ll build vendor-agnostic tooling for MCU and peripheral integration to solve hardware-software integration once and for all. We work at the intersection of embedded systems, code generation, compilers, and machine learning. It’s your chance to help redefine how low-level development is done.
Responsibilities
- Drive the architecture of the driver structures and system layout
- Define scalable patterns for cross-architectural integration across bare-metal, Zephyr, Linux, and other environments
- Deconstruct complex SoC device trees and translate hardware descriptions into structured internal models for automated reasoning
- Partner with the ML team to shape data and annotation models for AI-driven data-extraction tooling
Qualifications
- 5+ years of experience in embedded systems development, including bare-metal and RTOS-based systems
- Proficiency in C/C++
- Familiarity with firmware configuration, SoC bring-up, and system-level debugging
- Hands-on experience with code generation tools, or low-level compiler/decompiler/emulator technologies
- Strong background in embedded toolchains: compilers, linkers, debuggers, and build systems
- Python or scripting for automation and tooling is a plus
- Experience with functional-safety standards is a plus
Why embedd.it?
- Dynamic, venture-backed team of engineers challenging the status quo 🚀
- Work at the intersection of embedded systems, code generators, compilers, and ML 🤖
- Unusual challenges requiring out-of-the-box abstract thinking 🧠
- Competitive compensation: cash + equity 💰
- Remote work possible 🌍
About Us
embedd.it is a UK-based startup reinventing embedded development. Our platform transforms unstructured semiconductor data into structured digital twins, enabling automatic generation of drivers, tests, and documentation. We're building a single, traceable source of truth to make integration fast, vendor-agnostic, and future-proof.
