Full-stack Engineer

• Productionize AI Workflows: Transform raw AI prompts and experimental logic into resilient production code using .NET 10/C# 14.
• Architect Agentic Systems: Design and build the "Agent Loops" (Planning → Execution → Observation) that allow our AI to interact reliably with our internal databases and external APIs.
• Build for Reliability: Implement "Evals" and Guardrails to manage the non-deterministic nature of LLMs, ensuring outputs are safe, accurate, and consistent for our users.
• Cloud Infrastructure: Partner with the Head of Tech to design and deploy the Azure/AWS infrastructure required to support high-concurrency AI workloads, focusing on latency and cost-per-token optimization.
• AI-First Tooling: Lead the team in adopting and optimizing AI-assisted development workflows (Claude Code, Cursor, etc.) to maintain our 10x velocity.
• Strategic Evolution: Collaborate on the long-term technical roadmap, identifying when to use fine-tuned Small Language Models (SLMs) vs. Frontier LLMs.

• - Support day-to-day supply chain operations across all group business units, including core fulfilment operations, contract packing operations, custom packaging, manufacturing, logistics, and packaging, ensuring orders, materials, and services flow efficiently across the group.
• - Coordinate contract packing operations by working closely with customers and internal planning teams to schedule jobs in line with capacity, timelines, and material availability, ensuring smooth execution from order confirmation through to completion. This includes raising, processing, and progressing production orders, managing job administration, and coordinating associated invoicing.
• - Act as the central point of coordination and customer contact for contract packing jobs, providing regular updates on order and job status, progress, and completion, responding to customer queries, and proactively managing issues, changes, or delays as they arise.
• - Manage the end-to-end administrative processing of contract packing and wider supply chain activities, including order entry and progressing, maintaining job and order documentation, supporting job costing, processing purchase orders, and generating, processing, and reconciling customer and supplier invoices to ensure accuracy against agreed specifications and pricing.
• - Monitor group-wide raw material requirements, including packaging and manufacturing inputs, and manage the replenishment process. This includes raising, tracking, and progressing purchase orders to ensure correct stock quantities are maintained in line with production plans, contract packing activities, and demand requirements, as well as coordinating deliveries to support manufacturing and distribution operations.
• - Support Vendor Managed Inventory (VMI) processes for packaging by monitoring usage across the group, coordinating replenishment with suppliers, maintaining accurate stock, order, and usage records, and supporting supplier performance, reconciliation, and invoicing activities.
• - Support custom packaging projects by acting as an intermediary during the discovery and early development stages, coordinating communication between customers, internal stakeholders, and production partners, and assisting the Head of Supply Chain with supplier engagement, pricing support, and the transition from concept to production.
• - Support logistics operations by arranging and booking transport for inbound and outbound shipments, preparing and issuing relevant shipping documentation, tracking and progressing deliveries, and proactively following up on delays, discrepancies, or service issues with logistics partners.
• - Liaise closely with customers, suppliers, transport providers and internal teams to ensure orders, materials, packaging, and services are delivered in line with operational requirements, service levels, and agreed timelines.
• - Maintain accurate and up-to-date supply chain, order, and financial data across systems, supporting reporting, audits, invoicing, financial reconciliation, and operational visibility across the group.
• - Provide general supply chain, customer service, and operational administration support to the Head of Supply Chain, contributing to continuous improvement initiatives and identifying opportunities to improve efficiency, accuracy, service levels, and customer experience across the group.
