ERP Process Engineer

What you'll do

• Own the company-wide implementation and operation of SAP S/4HANA Cloud, Public Edition, from fit-to-standard design and configuration through testing, migration, deployment, adoption, and continuous improvement. 

• Define the future-state business processes that will underpin Hypersonica’s operations across finance, procurement, supplier management, inventory, warehousing, manufacturing, quality, maintenance, sales, and logistics. 

• Act as the single point of accountability for the SAP programme, owning the roadmap, delivery plan, implementation partners, critical decisions, dependencies, risks, and business readiness. 

• Translate complex and often incomplete operational requirements into scalable, standardised SAP processes that support speed, traceability, and production readiness. 

• Build the master data, governance, access, approval, and reporting structures required to make SAP the company’s operational source of truth. 

• Own the implementation of serial and batch traceability, production orders, inventory control, quality records, procurement workflows, and other controls required for high-consequence hardware manufacturing. 

• Lead system integration between SAP and Hypersonica’s wider technology environment, including engineering, manufacturing, HR, CRM, reporting, identity, document management, and other business-critical platforms. 

• Own the rollout and optimisation of associated SAP products, including SAP Sales Cloud and SAP SuccessFactors, where they support the wider business systems architecture. 

• Establish the SAP operating model, including process owners, super users, training, support, release management, regression testing, issue escalation, and continuous improvement. 

• Drive adoption across the business, ensuring teams use the system correctly and that parallel spreadsheets, disconnected workflows, and unofficial sources of truth are removed. 

• Build clear programme and systems reporting for leadership, including implementation progress, adoption, data quality, risks, control gaps, and business outcomes. 

• Select and manage implementation partners and software vendors, ensuring they deliver against Hypersonica’s pace, quality bar, and operational requirements. 

• Ensure business systems remain secure, controlled, audit-ready, and aligned with relevant quality, financial, security, and regulatory expectations. 

Who you are

• A senior SAP or enterprise systems leader with a proven record of implementing SAP S/4HANA Cloud, Public Edition across a complex physical-product business. 

• You have led a major ERP implementation end to end, not simply supported one module or maintained an already mature system. 

• Experienced across multiple operational domains, ideally including manufacturing, procurement, inventory, warehousing, finance, quality, maintenance, and supply chain. 

• Strong in business process design and able to turn fragmented company practices into coherent, scalable operating processes. 

• Deeply familiar with fit-to-standard implementation and confident challenging executives and functional leaders when unnecessary customisation creates long-term risk. 

• Comfortable owning implementation partners, programme plans, budgets, dependencies, data migration, testing, training, cutover, and business adoption. 

• Able to operate credibly with both senior leadership and functional users, translating between operational needs, system architecture, and implementation reality. 

• Technically literate across integrations, APIs, identity and access, master data, permissions, reporting, and business application architecture.
