Job Description As COO, you'll sit on the executive team reporting to the CEO, working closely with peers across product, commercial and finance. Your remit is to build and lead the central operating functions that support the development, readiness and day-to-day execution of the Constellation ecosystem, ensuring the business scales in a coordinated and repeatable way. That means bringing together hardware and consumable manufacturing, supply chain, quality and business operations into a coherent, data-led operating model. This is a role for a proven ‘mountain climber’. We plan to move from early pilot deployments to commercial scale installations, and the organisational capability behind that transition needs to be designed, built and run with real rigour. You’ll recruit and mentor senior leaders across Manufacturing, Supply Chain, Quality and Business Operations, and establish the operating rhythm that ensures the business runs in a coordinated, disciplined and repeatable way as it scales. Our growth requires us to widen our operational capability, with this role sitting alongside our current COO who will narrow their role to one of Chief Delivery Officer, overseeing Product Development teams and all customer-facing delivery. What you'll do You'll get to define what operations looks like at Cellular Origins, from the first pilot builds to coordinated multi system, multi-geography scale. You'll get to design the operating model that takes Constellation systems reliably from engineering handover through manufacturing, build and test, and into readiness for deployment. You'll lead the build-out of teams, processes and performance measures that keep pace as production volumes and organisational complexity grow. You’ll ensure the organisation consistently produces systems that are built, tested and consistently ready for deployment, with installation and commissioning in customer facilities owned by our delivery function. You'll help embed a culture that holds safety, quality and accountability as genuinely non-negotiable, while staying open to learning as the business evolves. You'll lead senior hires across the operations function, mentoring leaders who can each own their domain as the business scales internationally. You'll explore how digital systems, ERP, QMS and operational data can drive better visibility and decision making across the whole operating model. You'll help shape how Cellular Origins plans and allocates resources across manufacturing, supply chain and business operations, so that every function moves in step with the others.
