We’re Trezor , a leading company in crypto security who pioneered the hardware wallet industry.
We’re looking for an Embedded Software Engineer to join our dynamic firmware team and play a key role in designing and implementing the kernel for our next-generation hardware wallet. If kernel development isn't your thing, don't worry - we have a variety of other exciting projects where your skills can make a big impact.
You'll be responsible for the low-level code of Trezor hardware wallets, working on both development boards and real devices. You’ll contribute to the decision-making process for developing new models . If there are any hardware-related issues, you will be able to address them.
This is an excellent opportunity for an engineer who is passionate about developing cutting-edge technology, to join us and be at the forefront of the cryptocurrency revolution.
👉 What will your duties be?
- You’ll work on Trezor Core - firmware for Trezor hardware devices
- Your day-to-day tasks will consist of:
- designing, prototyping, and testing high-quality embedded code
- ensuring the robustness of the code in the face of heavy-duty hardware use
- cooperating on the design of possible future hardware revisions
- maintaining and improving the performance of existing software
-
Since our work is open source, you can have a look at our Github to see what we’re currently working on
- Programming languages: C, Rust and MicroPython
- STM32, nRF52 microcontrollers
- I2C, SPI, UART, USB, Bluetooth and NFC communication protocols
-
Git & GitHub
- You have experience with embedded software development
- Proficiency in C programming language
- Knowledge of ARM TrustZone is a big plus
- Willingness to learn Rust
- Proven skills in writing code for microcontrollers
- You’re comfortable with Git
- You're familiar with low-level communication protocols
- We’ll also appreciate it if you have an understanding of the underlying electronics
-
You have a positive attitude and desire to learn new things
- Unique opportunity to be a part of a brand that has revolutionized the crypto industry more than once
- Ability to receive part of your compensation in bitcoin
- Autonomous development - We do not work in a clear assignment/delivery model. While we do have priorities and backlogs, no assignment is pixel-perfect and you are the person to figure out the last mile. We also encourage people to tell us what we should do next
- Flexible working hours as well as the possibility of working from home
- Budget for professional development (training programs, courses, and workshops of your choice)
- Renovated offices (including gym, football table, billiards, PlayStation and 3D printer)
- Other benefits such as a MultiSport card, company mobile phone tariff, etc.

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.
