3What this role really is

An Associate Firmware Engineer fixes small bugs and builds well-defined features in low-level embedded code.

4What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

C/C++ Programming Language Intermediate

Writing and debugging application-level firmware code, implementing bug fixes, and adding small features.

GCC/Clang Compiler Basic

Compiling your code using existing Makefiles or build scripts. You'll learn how to interpret basic compiler warnings and errors.

Python (for scripting) Basic

Running existing test scripts, automating small tasks, or potentially writing simple scripts to parse log files.

Git (Version Control) Intermediate

Cloning repositories, committing your changes, pushing to remote, creating pull requests, and resolving simple merge conflicts.

J-Link/ST-Link Debugger Basic

Connecting to target hardware, setting breakpoints, stepping through code, inspecting variables and memory in an IDE like VS Code or Eclipse.

Oscilloscope/Multimeter Basic

Verifying basic signal levels, checking clock frequencies, and confirming I/O behaviour under guidance from a senior engineer.

5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Code Changes All code changes, even minor bug fixes, require a thorough code review and approval from a more senior engineer before merging to the main branch. Routine code changes and new features within an existing module can be merged after peer review. Significant architectural changes or new module introductions require senior approval. Technical decisions within your owned subsystem or workstream. You'll make choices on implementation details, tool selection, and methodology, but consult on broader architectural impacts.
Debugging Approach Follow established debugging procedures. Escalate to your manager if a bug is complex, unreproducible, or takes more than a few hours to diagnose. Independently diagnose and fix most bugs within your area. Propose new debugging strategies for tricky issues. Define debugging strategies for complex system-level issues. Lead the effort to resolve 'heisenbugs' and intermittent failures across subsystems.
Hardware Interaction Perform basic hardware tests (e.g., verifying signal levels with a multimeter) under direct supervision. Do not modify hardware without explicit permission. Independently use oscilloscopes and logic analysers to diagnose hardware/firmware interface issues. Suggest minor hardware modifications to improve firmware performance. Collaborate closely with hardware engineers on PCB design reviews, influencing component selection and layout for optimal firmware performance and debuggability.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Task Completion Rate
How many of your assigned tasks (bugs, small features) you finish within the estimated time.
Target · Roughly 80-90% of assigned tasks completed on time.

If you're given 5 small bug fixes in a sprint, we'd expect you to get 4-5 of them done and properly tested.

Code Review Feedback Cycle Time
The average time it takes for your code to pass review and get merged, including any revisions you need to make.
Target · Aim for a 1-2 day turnaround for initial feedback and subsequent revisions.

You submit code on Monday, get feedback Tuesday, make changes Wednesday, and it's merged Thursday. That's a good cycle.

Number of Critical Bugs Introduced
How often your changes inadvertently cause a major, show-stopping bug.
Target · Ideally, zero critical bugs. If one pops up, it should be a rare occurrence.

Your code change should not cause the device to randomly reset or stop communicating entirely. If it does, we'll work together to understand why.

Learning & Application
How effectively you're absorbing new technical concepts and applying them in your work. We want to see you growing!
  • Asking thoughtful questions, showing initiative in learning new tools/protocols, successfully implementing new concepts after being taught, fewer repeat mistakes on similar problems, actively participating in team learning sessions.
Documentation Quality
How well you document your code, changes, and any new processes you learn or create.
  • Clear, concise comments in code, well-structured READMEs for new modules, updating existing documentation when you make changes, following our team's documentation standards, making it easy for others to understand your work.
Proactive Problem Solving (within scope)
Your willingness to try and figure things out for yourself before immediately asking for help, especially for routine issues.
  • Attempting to debug an issue using standard tools (debugger, oscilloscope) before escalating, clearly explaining what you've tried when asking for help, suggesting potential solutions, taking initiative to find relevant datasheets or existing code examples.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Building Tangible Things

You get a real kick out of seeing your code directly control a physical device – a blinking LED, a spinning motor, data appearing on a screen. The satisfaction comes from bringing hardware to life.

Successfully getting a new sensor to read data for the first time after hours of 'datasheet diving' and coding.

Mastering Complex Systems

You enjoy the intellectual challenge of understanding how microcontrollers, peripherals, and real-time operating systems all fit together. You want to peel back the layers and truly grasp the low-level details.

Spending extra time to understand why a specific interrupt priority level is chosen, rather than just copying the example code.

Continuous Learning

You're always looking to pick up new skills, whether it's a new communication protocol, a different microcontroller architecture, or a better way to debug. The idea of constantly expanding your knowledge base excites you.

Voluntarily reading up on the latest features of our chosen RTOS or exploring a new debugging technique mentioned by a colleague.

What frustrates people
  • The 'hardware/software blame game' – where everyone thinks the other side's at fault for a bug.
  • Spending hours 'datasheet diving' to understand a single register setting that's poorly documented.
  • Chasing 'heisenbugs' that only appear intermittently or under very specific, hard-to-reproduce conditions.
  • Toolchain issues – compilers, linkers, or debuggers that just refuse to cooperate, wasting a whole morning.
  • The physical world is messy – voltage fluctuations, EMI, or a dodgy solder joint messing up your perfectly written code.
  • Having to wait weeks for a new 'board spin' to fix a hardware issue that's blocking your software development.
What this role does not give you
  • Lots of independent decision-making – you'll be guided closely.
  • High-level strategic work – that comes later in your career.
  • A perfectly clean, greenfield codebase – you'll be working with existing systems.
  • Instant gratification – debugging can be a slow, methodical process.

8Who you work with

Your work, even at this early stage, directly contributes to the stability and functionality of our core products. Getting small features right means fewer bugs later on for the senior folk. You're building the foundations, ensuring the underlying tech is solid. Frankly, if the firmware doesn't work, the product doesn't work, full stop. You're a crucial part of getting our innovations from concept to customer's hands.

Inside the business
  • Your direct manager (Firmware Engineer/Senior Firmware Engineer)
  • Other Firmware Engineers (for code reviews and learning)
  • Hardware Engineers (to understand schematics and board layouts)
  • Test Engineers (to help them test your code)
Outside the business
  • Component Vendors (you'll use their datasheets, but won't directly interact)

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • A degree in Electronic Engineering, Computer Science, or a related field (or equivalent practical experience).
  • Some practical experience with embedded systems, perhaps from university projects, internships, or personal hobbies (e.g., Arduino, Raspberry Pi, custom PCB projects).
  • A solid grasp of C/C++ programming fundamentals, including pointers, memory allocation, and data structures.
  • Familiarity with version control systems, particularly Git.
  • A genuine curiosity for how hardware and software interact at a low level.

10What to practise next

Where the job is going, and what to do about it starting this week.

Advanced Debugging & System Analysis

As devices get more complex, bugs become harder to find. Relying solely on breakpoints won't cut it. You'll need to master more sophisticated techniques.

Real-time tracing (ETM/ITM) · Logic analyser mastery · Crash dump analysis · Power profiling

  • This week: Ask a senior engineer to show you how they use the logic analyser.
  • This month: Try to diagnose an intermittent bug using a combination of software and hardware tools.
  • Month 2: Read application notes on advanced debugging features of our microcontrollers.
  • Month 3: Propose a new debugging technique for a recurring issue.

Quick win: Get comfortable with all the features of your IDE's debugger beyond just breakpoints. Explore watchpoints and memory views.

11Staying current once you are in

What people here do to keep up
  • Actively participate in online embedded systems communities (e.g., EEVblog forums, Stack Overflow).
  • Follow industry blogs and publications to stay up-to-date on new microcontrollers and tools.
  • Take online courses (Coursera, Udemy) on specific protocols (e.g., CAN, USB) or RTOS concepts.
  • Build personal projects using microcontrollers to experiment with new hardware and software techniques.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, firmware development can be a bit of a grind sometimes. Reading endless datasheets, writing boilerplate code, and trying to decipher cryptic error messages. What if you could cut down on some of that tedious stuff? Our team is embracing AI to make us all more productive, giving you more time to focus on the truly interesting challenges.

We're not talking about AI writing your entire firmware (not yet, anyway!). We're talking about smart tools that act like a super-powered assistant, helping you with the repetitive, time-consuming parts of the job. This means you can get more done, learn faster, and spend less time fighting with documentation.

Smart Snippet & Driver Generation

Imagine typing a comment like 'Generate an I2C read function for the BME280 sensor' and having GitHub Copilot (or similar) spit out the boilerplate code for you. It's fantastic for ISRs, HAL functions, and common communication protocol handlers. You'll still need to understand it and tweak it, but it saves loads of typing.

AI-Powered Datasheet Assistant

Forget endlessly scrolling through 1,000-page PDFs. Use an LLM to 'chat' with a microcontroller reference manual. Ask direct questions like, 'What are the exact register settings to configure Timer B for 100Hz PWM?' and get an instant, summarised answer. It's a game-changer for 'datasheet diving'.

Automated Documentation & Release Notes

Point an AI tool at your Git commits and have it automatically draft Doxygen comments for your code or summarise your bug fixes for release notes. It won't be perfect, but it's a brilliant starting point, saving you from staring at a blank page.

Code Explanation & Refactoring Suggestions

Stuck trying to understand a complex piece of legacy code? Feed it to an AI and ask it to explain what it does, step-by-step. You can also get suggestions for how to refactor messy functions into cleaner, more readable code. It's like having a senior engineer on call 24/7.
