This is a hands-on role where you’ll be responsible for implementing new features, resolving issues, and improving the quality of our specification workflows. You’ll work closely with experienced engineers and specification authors, contributing to the efficiency and reliability of a growing platform
Responsibilities
- Develop and improve Python tools for working with YAML/XML/JSON based specifications.
- Implement and test software components that validate or transform architectural specification data.
- Contribute to improving the authoring experience and consistency of specifications.
- Collaborate with partners across IP development and tooling teams to understand requirements.
-
Participate in code reviews and help maintain a high standard of code quality and documentation.
- Proficiency in Python or a similar programming language..
- Strong problem-solving skills.
- Experience using Git for version control and collaborative development.
- High attention to detail and a commitment to writing clean, maintainable code.
- Ability to work independently while knowing when to seek guidance.
- Effective written and verbal communication skills in English.
- Awareness of coding standards, testing, version control, and automation best practices.
-
Ability to use Bash or other shell environments for scripting and development workflows.
- Understanding of build systems, testing frameworks, and CI environments (e.g., Jenkins CI).
- Proficiency in manipulating structured data formats such as XML, JSON, and YAML.
- Basic understanding of Makefiles and build automation.
- Familiarity with schema validation techniques (e.g., XSD, JSON Schema).
- Experience writing or maintaining user documentation using Sphinx or similar tool.
-
Interest in hardware design concepts (e.g., registers, memory maps, interrupts, clocks, resets).

Hybrid Working at Arm
Arm’s approach to hybrid working is designed to create a working environment that supports both high performance and personal wellbeing. We believe in bringing people together face to face to enable us to work at pace, whilst recognizing the value of flexibility. Within that framework, we empower groups/teams to determine their own hybrid working patterns, depending on the work and the team’s needs. Details of what this means for each role will be shared upon application. In some cases, the flexibility we can offer is limited by local legal, regulatory, tax, or other considerations, and where this is the case, we will collaborate with you to find the best solution.

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.
