Responsibilities
The Opportunity
We’re hiring a Senior RF Embedded Systems Engineer to lead the design, development, and prototyping of our next-generation IoT tracking devices. You’ll be the first technical hire on the hardware engineering side—owning circuit design, firmware, integration, and RF performance in a tight feedback loop with product and manufacturing teams.
This is a high-impact, hands-on role where you’ll take a concept from napkin sketch to functional prototype, validate performance, and work closely with our GM of Hardware and contract manufacturers to scale it into production.
What You’ll Do
- Design and prototype embedded systems for low-power, RF-connected devices (LoRa, LTE-M, BLE, GNSS, etc.).
- Develop and debug firmware on microcontrollers using C/C++
- Design and test RF circuits, antennas, and matching networks for reliable comms in field environments.
- Build and validate custom PCBs (schematics, layout guidance, component selection).
- Conduct bench-level testing, including signal analysis, power profiling, and RF range validation.
- Implement FIPS 140-3 compliant encryption and secure boot mechanisms to meet DoD cybersecurity requirements.
- Create test plans and documentation for transitioning prototypes to manufacturing.
- Collaborate closely with contract manufacturers and hardware leads to support DFM, DFT, and QA workflows.
-
Support FCC, TAA, or MIL-STD pre-certification efforts as needed.
What We’re Looking For
- 5+ years of experience designing embedded systems with integrated RF components.
- Strong knowledge of RF fundamentals, modulation, and low-power wireless protocols.
- Experience with embedded firmware development and debugging in constrained environments.
- Proficient in lab testing with tools like oscilloscopes, spectrum/network analyzers, and signal generators.
- Familiarity with implementing FIPS-compliant cryptographic modules and secure key storage.
- Able to take full ownership of board bring-up, debug, and field validation.
-
S. Citizenship with the ability to obtain and maintain a government security clearance.
- Experience with LoRa, LTE-M/NB-IoT, GNSS, UWB, or BLE in constrained environments.
- Previous work in DoD, aerospace, industrial IoT, or high-reliability sectors.
- Familiarity with Altium, KiCad, or similar for schematic capture and layout review.
- Python, MATLAB, or similar for signal/data processing and RF analysis.
- Hands-on experience with environmental or EMI/EMC testing workflows.
-
Open-source hardware or firmware contributions.
You won’t just be coding firmware or simulating RF—you’ll be building the foundation of a new hardware product line that’s headed straight into real-world military use. You’ll see your designs go from bench to battlefield.

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.
