Product Reliability Engineer Hardware, Software, and Systems

A brilliant opportunity for a hands-on Product Reliability Engineer 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 (3–4 days per week in office)

Salary: Competitive + equity options + healthcare

Requirements for Product Reliability Engineer

• Proven experience within product reliability, systems testing, or validation—gained through academic study, personal projects, or commercial roles
• 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
