About Celtic Renewables

Celtic Renewables are widely regarded as one of the most innovative Biotech companies in Europe, having developed technology patent(s) for the conversion of biological residues into sustainable green chemicals. The process is an inspirational reinvention of a century old process known as the Acetone-Butanol-Ethanol (ABE) fermentation, to bring this age-old fermentation back to the global scale. The green chemicals produced by this innovative process are highly sought after across a range of industries - from cosmetics, food flavourings, hygiene, pharmaceuticals through to use for biofuels. This pioneering company has completed construction of a state-of-the-art processing plant in Grangemouth, a historical exemplar plant for Scotland, and are operating at a commercial scale.

This first commercial plant is the launching pad for our ambitious international growth plans. The Grangemouth facility is the exemplar to building larger scale facilities across the UK and internationally. The recruitment of additional

into the business is part of our strategic growth plan to enhance our internal talent pool to help develop future project opportunities.

Key Duties & Responsibilities

As a Process Operator you will safely and efficiently operate the main process production areas, consisting of a multi-stage batch fermentation process and continuous distillation plant, as part of a shift rota (12 hour day and night shifts). You will have a process/manufacturing background and will naturally and strictly follow the instructions as outlined in site procedures, always ensuring compliance and quality. Work with the Production Manager to help develop procedures and risk assessments. You will coordinate and schedule the unit operations of the plant to ensure that the plant runs efficiently and continuously. You will always display safe and hygienic working practices and will ensure that the requirements of the Integrated Management System are strictly followed to ensure compliance with H&S, Environmental and other legal requirements to produce safe products and co-products which meet strict quality parameters. You will understand the requirements of REACH, SEPA, FEMAS and COSHH, and apply these in your role. You will operate, manage and continually contribute to the optimisation of the production processes, from raw material intake to outgoing product.

Skills, Experience & Qualifications

You will have previous solvent/chemical/distillation production experience or experience of operating a plant within a related manufacturing sector. The plant is highly automated, so you must be proficient in the use of Digital Control Systems (e.g. Siemens, Delta V, Honeywell, etc) and be familiar with associated automated plant, equipment and instrumentation. You will be comfortable operating in a dynamic role where processes change and you need to adapt quickly. This involves creation and updating site operating procedures and plant schedules, and communicating these with the wider operations team. Ideally you will have an understanding or have knowledge of hygienic/sterile manufacturing operations and environment. From your previous experience you will be able to demonstrate your knowledge and experience of working strictly within defined safety, environmental, quality and feed safety standards and procedures.
