Job description

Senior Software Engineer – Python / Hardware Systems

Do you want to build real-world machines that handle complex tasks with speed and precision. This isn’t app or web dev, it’s embedded Python, hardware integration, and system-level thinking. We’re looking for someone who writes robust code, understands how systems behave in the wild, and knows how to push hardware and software to work together seamlessly.

What you’ll be doing :

Writing Python to interface with motors, sensors, relays, power systems, and I / O
Designing and maintaining services that run on embedded Linux (often headless)
Working with serial protocols (UART, I2C, SPI), MQTT, CANbus, Modbus etc.
Handling real-time constraints, task scheduling, and resource-limited environments
Debugging across layers : device logs, serial traces, signal timing, and hardware behaviour
Building automated test rigs and simulation tools to catch bugs early
Optimising code for performance, memory, and reliability at the edge

Tech you might use or encounter :

Python (asyncio, multiprocessing, struct, ctypes, pytest)

Linux (systemd, udev rules, shell scripting, device trees)

Microcontrollers and SBCs (Raspberry Pi, BeagleBone, STM32, ESP32)

Networking and messaging : ZeroMQ, MQTT, TCP / UDP sockets

ROS, FreeRTOS, or similar frameworks for real-time or robotics

Docker, CI pipelines, version control (Git), and hardware-in-the-loop testing

Occasional interaction with backend systems (Nest.js, Postgres) for telemetry and config

What we’re looking for :

Strong Python skills in embedded, automation, or device-heavy environments

Confident with low-level comms, device integration, and hardware abstraction

Knows how to debug flaky hardware, noisy signals, and time-sensitive code

Understands performance trade-offs, concurrency, and memory management

Bonus if you’ve worked on robotics, IoT, industrial control, or real-time systems

Comfortable owning problems end to end, from code to field deployment

Why join :

Small team, real impact, and problems that require actual engineering.
