About Us
Concrete4Change (C4C) is building one of the most commercially viable CO₂ mineralisation platforms globally.
We are past the lab stage. The technology is already running at pilot scale (~3 tonnes/year). The next step is clear: scale to a demo plant (~300 tonnes/year) and make the process fully controllable, repeatable, and industrially robust.
Backed by major industrial partners (Holcim, Goldbeck), we are now solving the hardest problem: making chemistry behave in real systems, continuously, under real constraints.
The Role
This is a process analytics ownership role.
We are looking for a Process Analytical Chemist who can take our current set of analytical techniques and translate it into a fully instrumented, data‑driven, and controllable system at an industrial scale.
Build the analytical backbone that allows the process to run reliably at 300 t/year.
* Defining what to measure
* Measuring it properly (inline and online)
* Using that data to control and stabilise the process
If you are not obsessed with real data and real systems, this is not the role.
What You Will Actually Do
* Take existing pilot‑scale analytical methods and translate them into robust inline and online analytical systems
* Design and implement process analytical technology (PAT) frameworks across the plant
* Measure critical process variables:
o gas and liquid concentrations
o gas and liquid impurity profiles
o particle formation and evolution
* Build measurement systems that work in reality:
o not clean samples
o not ideal and varying conditions
* Work directly with engineers to integrate analytics into process control loops
o detect drift early
o ensure optimal and repeatable reaction and process conditions
o control impurities
* Identify what matters vs what is noise — and eliminate unnecessary measurement
o fouling of probes
o lag in measurements
o mismatch between lab and plant data
* Define and implement QC systems that hold at scale
* Support scale‐up from 3 t/year pilot → 300 t/year demo, ensuring analytical systems scale with the process
* Be on the plant floor when things fail — and fix them using data
PhD in Chemistry, Analytical Chemistry, Materials, or Chemical Engineering (or equivalent real‑world experience)
Strong experience in process analytical chemistry / PAT in industrial or pilot environments (TRL 5–8+)
Hands‑on experience with inline and online analytical techniques (not just offline lab work)
Proven ability to translate analytical methods from lab to real process environments
Strong understanding of:
* precipitation and crystallisation systems
* multiphase processes
* impurity tracking
Experience integrating analytics with process control and plant operation
You have solved real problems with sensors, data, and messy systems — not idealised ones
High ownership, speed, and ability to operate under pressure
Strong Signals (We Will Prioritise)
* You have built or deployed PAT systems in pilot or industrial plants
* You have worked on scaling analytical systems alongside process scale‑up
* You understand limitations of real sensors and how to work around them
* Experience turning poor/uncertain data into actionable process control
* Ownership of the analytical backbone of a system scaling from pilot → demo → industrial
* Equity in a company targeting large‑scale decarbonisation
* Direct work with industrial partners and real plant systems
* Fast progression based on output
* No bureaucracy — only execution
Final Note (Read Carefully)
This role is about making measurement real.
* clean samples
* perfect instruments
* delayed lab analysis
* or theoretical optimisation
this is not for you.
If you want to:
* build real‑time analytical systems
* control a process as it runs
* and see your work directly impact a 100x scale‑up
