- Debug critical firmware issues impacting performance, stability, and throughput.
- Collaborate with hardware, RF, and systems teams to ensure optimal firmware operation across layers.
- Develop and optimize firmware for real-time embedded environments, ensuring compliance with timing constraints and system KPIs.
- Participate in code reviews, bring-up, and delivery of firmware to production hardware.
-
Support regulatory (FCC, ETSI etc.,) and feature compliance (e.g., DFS, CCA, Spectral Scan, etc.).
- Be part of a Firmware Innovation Group under experienced leadership.
- Work on next-generation wireless technologies with cross-functional teams in a global environment.
- Work on bleeding-edge platforms and direct engagement with chipset vendors.
-
A growth-oriented, fast-paced R&D culture where firmware leads the product innovation
- 5–8 years of embedded software development focused on Wi-Fi or Cellular firmware.
- Strong knowledge of IEEE 802.11 protocols, especially Wi-Fi 6 and Wi-Fi 7 (MAC/PHY level) or similar technologies in Cellular(LTE/5G)
- Experience in real-time embedded systems and RTOS environments.
- Solid debugging skills for firmware bottlenecks, stability issues, and low-level Wi-Fi/Cellular stack problems.
- Hands-on experience with Qualcomm and/or Broadcom or MediaTek or Intel (or any other chipsets)
-
Experience with Debugging tools: Wireshark, GDB, iperf, Sniffer
- Experience with Qualcomm Wifi/Cellular chipsets
- Basic experience in host-side driver development (cfg80211/nl80211, netlink communication).
- Familiarity with Linux wireless applications (e.g., hostapd, wpa_supplicant).
- Knowledge of OpenWRT, Yocto, QSDK, and user-space tools for embedded Wi-Fi platforms.
- Knowhow about TDD/TDMA, FDD/FDMA
- Basic understanding of bootloaders, BSP bring-up, and U-Boot configuration.
- Familiarity with RF-related features such as:
- DFS
- Spectral Scan

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.
