ERP Process Engineer

Help Build Europe’s Hypersonic Capability

At Hypersonica , we’re redefining what’s possible in European defence technology. We exist to deliver speed, resilience, and technological independence at a pace that sets a new standard. We are a small, elite team working on problems that matter, and solving them fast.

By joining Hypersonica , you’re not stepping into a predefined role. You’re joining a talent dense environment where every individual shapes the direction of the company. Our philosophy is to hire a small number of exceptional people with broad, deep technical capability, strong judgement, and the ability to operate autonomously.

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.

What we offer

• A mission-driven environment with the opportunity to work on one of Europe’s most consequential defence challenges, with direct impact on sovereign capability and security.
• Daily collaboration with leading experts across engineering, operations, business development, and defence, with genuine opportunities to learn, contribute, and grow.
• Exposure to the full lifecycle of complex defence programmes, from customer requirements and commercial strategy through to engineering delivery and flight testing.
• High ownership and autonomy: no time tracking and no micromanagement, just clear objectives and accountability for outcomes.
• A fast-paced environment where good ideas are implemented quickly and feedback from testing and flight drives real decisions.
• A culture that values clarity, integrity, and excellence, and supports people who take initiative and push boundaries responsibly.
• Competitive compensation and real share options aligned with responsibility and impact, not tenure or hierarchy.
