Senior Control & Automation Engineer
Application Deadline: 12 July 2026
Department: Engineering
Employment Type: Permanent
Location: Bristol
Compensation: £49,410 - £71,370 / year
Description
Do you want to help build a company with the capacity to disrupt whole industries and take on environmental issues on a global scale?
Do you want to join a purpose-driven engineering team tackling some of the world’s most critical challenges?
Matter. is a VC backed Cleantech scale-up that develops industrial scale modular microplastic filtration systems. We have an opportunity for a Senior Control & Automation Engineer to establish and lead internal product development capability across industrial control systems and instrumentation, whilst leveraging data-driven insights from in-field products.
This is a senior, hands-on engineering role, combining technical leadership with practical delivery. The role is based in Bristol, UK, with occasional travel to industrial customer sites to gain in-field experience and gather insights during commissioning and reliability troubleshooting.
Job Title: Senior Control & Automation Engineer
Location: Central Bristol - hybrid
Salary Range: £49,410 - £71,370 per annum
Matter. are innovators in water filtration, developing pioneering filtration technology to capture microplastics and cut carbon emissions. You will be working on some of the biggest challenges of our time, removing micropollutants from the world’s waterways.
Through brilliant design thinking, powerful partners, and impatience to make what we do matter, our mission is to transform industries through technology that empowers customers and protects the planet.
We pride ourselves on our amazing technology and passion for wanting to change things, but fundamentally what we are most proud of is our people.
For us, people are everything. It’s what makes a company, not the mission written on the wall or the fancy building we work in. Our people represent us, our values and why we do what we do.
The Opportunity
In this role, you will play a key role in the development, delivery, and support of complex engineering systems. The role operates within a hybrid delivery model, where the engineer manages and directs external contractors and suppliers, while building and expanding internal capability.
From the outset, the expectation is to lead technical direction, own supplier engagement and outputs, and drive the transition toward greater in-house ownership. Over time, this balance will shift toward a strong internal capability, with external partners used in a targeted and scalable way.
This role sits at the intersection of internal engineering and external specialist suppliers, acting as the technical authority for industrial control systems.
You will coordinate and direct external contractors, inform and shape technical decisions with internal leadership and progressively build in-house capability.
Initially, you will focus on existing supplier-delivered control systems, supporting field deployments and establishing robust data acquisition and analysis to validate product performance, customer ROI, and enable predictive maintenance. Over time, you will take increasing ownership of control systems, architecture, supplier strategy, and next-generation product development.
