[8BE] Team Lead - Back End Engineering

Project - the aim you'll have

We are seeking a highly autonomous engineer with a "Platform Engineering" mindset to take broad ownership of system-wide improvement. This project focuses on strengthening the core systems of a sophisticated, AI-powered product. Rather than traditional feature-based development, this initiative sits at the critical intersection of AI systems, infrastructure, and platform reliability. The team operates in a fast-moving, "early-stage" style environment, leveraging cutting-edge AI development tools to solve cross-cutting technical challenges. The mission is to evolve a complex codebase by improving observability, enhancing the reliability of AI agents, and ensuring the system can scale to meet high-performance demands.

If you enjoy solving complex technical problems across multiple domains and improving entire systems, this opportunity is for you.

Expectations - the experience you need

• 8+ years of professional backend development, including at least 4 years in a technical lead or team lead role
• Strong proficiency in C# / .NET (ASP.NET Core Web API, .NET 8) and clean architecture principles (DDD, CQRS)
• Hands-on experience designing and building RESTful microservices at scale
• Solid understanding of multi-tenant SaaS architecture patterns
• Experience with AWS services: Lambda, SQS/EventBridge, S3, RDS/PostgreSQL or DynamoDB
• Familiarity with Identity & Auth patterns: JWT, OAuth 2.0, OIDC; experience with Keycloak or similar identity providers
• Experience working in brownfield environments — assessing and integrating with existing systems
• Experience with containerisation (Docker) and CI/CD pipeline management (Bitbucket Pipelines or equivalent)
• Strong team facilitation skills: sprint ceremonies, code reviews, cross-vendor alignment

Nice to have

• Excellent communication in English — written and spoken — for daily client interaction
• Experience in retail, e-commerce, or B2B commerce domains — understanding of order lifecycle, pricing models, inventory management, and multi-channel fulfilment
• Familiarity with headless or composable commerce architectures and front-end/backend API contract patterns
• Experience with marketplace integrations (Amazon SP-API, Walmart Marketplace API)
• Background in promotional products, print-on-demand, or B2B e-commerce
• Experience working in distributed, multi-vendor delivery models

What you will do

• Lead and mentor a team of backend engineers (3–6 engineers), setting technical direction and ensuring consistent delivery quality
• Own sprint planning, backlog refinement, and capacity management in Jira in close coordination with the client's Product and Delivery teams
• Drive architectural decisions across core backend services: Identity & Auth, Order Management, Pricing, Inventory, Catalog, and Notifications
• Define and enforce engineering standards: code reviews, branching strategy, CI/CD pipelines, and testing coverage (xUnit, BDD/Reqnroll)
• Partner with the client's Project Manager and architects to align technical scope with POC, MVP, and full-launch phase boundaries
• Coordinate with the Shopify/Hydrogen front-end team and third-party vendors to ensure clean API contracts and integration points
• Navigate brownfield complexity — assess existing legacy systems, support migration planning, and ensure backward compatibility where required
• Proactively identify, surface, and mitigate delivery risks, dependencies, and blockers
• Participate in client-facing stand-ups, sprint reviews, and technical design sessions
• Ensure environment parity and observability across Dev, QA, Integration, Staging, and Production (AWS-hosted)
