Job Description
A brilliant opportunity for a hands-on Test Engineer (Hardware, Software, and Systems) to join a pioneering tech start-up working on innovative connected devices that blend hardware, software, and intelligent cloud systems. You’ll be joining a small, talented team at an early stage, helping to shape and test next-generation products designed to perform flawlessly in real-world environments.
Location: London (Ideally 5 days in the office)
Salary: £50k - £90k per annum + equity options + healthcare
Requirements for Product Reliability Engineer
* Strong experience as a Test Engineer testing hardware and software products
* This company values a strong academic history so is looking for someone who achieved a 2.1 or 1st class degree and at least AAB at A Level (or international equivalent)
* Comfortable working with both hardware and software systems, ideally including embedded or IoT-based products
* Practical ability to build or modify simple test setups using microcontrollers, sensors, or similar platforms
* Strong scripting or automation ability, ideally in Python (other languages such as Bash or Go are also welcome)
* Curious and analytical approach to investigating how systems work and identifying edge cases or weaknesses
* Strong communication and collaboration skills, comfortable working closely with cross-functional teams
* Interest in modern technology stacks and emerging product architectures (e.g. cloud-based or AI-assisted systems)
* Desirable: exposure to networking, sensors, or multimedia systems such as audio or video streaming
Responsibilities for Product Reliability Engineer
* Plan and carry out comprehensive system-level testing across connectivity, performance, and environmental conditions
* Proactively identify faults and bottlenecks to improve reliability, robustness, and scalability
* Design and maintain hardware test environments, integrating automation to streamline testing and data capture
* Write lightweight scripts or tools to coordinate, analyse, and visualise test outcomes
* Replicate realistic usage conditions—such as changes in temperature, motion, or signal quality—to evaluate performance
* Collaborate with hardware, firmware, and software engineers to validate complete system functionality
* Play a key role in evolving testing frameworks and ensuring reliability is built into designs from the outset
What the role offers
* Join a well-backed start-up at a formative stage, where your input genuinely shapes the direction of the product
* Work in a supportive, low-ego environment alongside experienced engineers and product specialists
* Access to cutting-edge technology and a culture that actively encourages experimentation and growth
