Job description

Link4 helps businesses exchange and process financial and business documents through eInvoicing and AP automation. The Pre-Sales Engineer provides technical expertise during discovery, solution design, and sales stages. The role is focused on connecting customer requirements with deliverable Link4 solutions. A strong background in software development, systems integration, or technical software delivery is essential. The role supports growth in the Philippines and other markets through accurate technical advice and effective implementation handovers.

Key Responsibilities

• Lead technical discovery with customers and partners: identify ERP versions, AP/AR workflows, document the customer requirements, integration interfaces, security requirements, regulatory needs and implementation constraints.
• Document the proposed integration method using supported Link4 APIs, SFTP and/or file-based interfaces. Define data flows, field mappings, attachments, business rules & validations, error handling and reconciliation requirements.
• Interpret API documentation and sample JSON, XML and CSV payloads; investigate routine technical questions and validate assumptions using approved test environments and tools during sales stages.
• Assess integration options for Oracle NetSuite, Microsoft Dynamics 365 (including Business Central), SAP and Oracle ERP / Fusion Cloud ERP. Identify required ERP configurations, customer access and implementation-partner dependencies.
• Conduct technical demonstrations and solution presentations tailored to customer needs. Explain integration options, limitations and responsibilities clearly to business and IT stakeholders.
• Prepare technical RFP, RFQ and tender responses, architecture diagrams and questionnaires. Verify statements against current product capabilities and supporting evidence before submission.
• Distinguish supported functionality, configuration and new development. Identify gaps, assumptions, risks and effort dependencies early, obtaining Product, Engineering or Project Delivery validation before commitments are made.
• Coordinate technical reviews within agreed sales and tender deadlines; track unresolved questions, accountable owners and decision dates, and **escalate blockers early.**
• Prepare a structured handover to Project Delivery covering agreed scope, systems, interfaces, mappings, testing and acceptance criteria, responsibilities, dependencies, risks and outstanding decisions.
• Develop knowledge of Link4 eInvoicing, Peppol and digital trade solutions and market-specific requirements. Maintain reusable technical knowledge and undertake related duties reasonably required for the role.

Key Performance Indicators

• Technical response timeliness: complete responses and reviews by agreed deadlines; elevate blocked items before those deadlines.
• Technical accuracy: track corrections and delivery rework caused by inaccurate or unvalidated pre-sales statements.
• Handover quality: obtain Project Delivery acceptance of required technical scope, dependencies and unresolved decisions before implementation starts.
• Risk identification and resolution: document material integration risks and capability gaps before proposals are committed.
• Technical contribution to sales: review outcomes of supported opportunities and demonstrations, alongside feedback from Sales, customers and Project Delivery. Targets are agreed with the manager.
