Lead .NET Engineer (Platform Architecture)

ProdigiCardiff, United Kingdom9 months ago

We’re hiring a senior technical leader to shape the architecture of Prodigi’s core platform. You’ll work hands-on in C#/.NET while defining the structures, service boundaries and system patterns that support our next-generation product: an API-first unified product creation, management and publishing engine. Your work will directly influence how all merchants, integrations and AI agents interact with Prodigi. You’ll focus on correctness, robustness, data integrity and long-term simplicity across systems that underpin millions of orders. This is a role for someone who wants architectural responsibility, not just feature delivery.

What You’ll Do

You’ll be shaping the foundations of a platform used by thousands of merchants and numerous integrations. Your work will influence our shipping engine, global routing logic, product creation pipelines, image processing, migration away from legacy stacks and the evolution of our public API. This is an opportunity to define the technical blueprint for Prodigi’s next decade.

Lead the technical design of new versions of our public API: domain boundaries, event flows, versioning, service interactions
Shape internal service design: caching, messaging, error handling, consistency, observability

Build Core Backend Systems

Design and implement backend services in C#/.NET that handle product modelling, shipping logic, routing and image/asset flows
Improve the robustness, clarity and consistency of core data models

Enable the Product Vision

Translate strategic goals into clear architectural direction for engineering
Work closely with Product to ensure designs scale across product creation, publishing and multi-channel integrations
Mentor engineers and set technical standards for the wider team

Improve Quality and Resilience

Reduce complexity by refining and refactoring legacy components

What We’re Looking For

Strong Architectural Capability

Deep experience designing and building distributed systems in .NET
Ability to define domain models and service boundaries for complex transactional platforms
Experience modernising or consolidating systems into clean, long-lived architectures
Strong grasp of eventing, queues, async flows and API design

Hands-On Technical Depth

Expert-level C# and .NET
Strong understanding of cloud services (Azure preferred)
Solid SQL and data modelling
Comfortable building, testing and operating production services

Engineering Leadership

Ability to set direction and provide technical mentorship
Confidence to challenge assumptions and propose simpler architectures
Ownership mindset in complex environments

Nice to Have

Experience in e-commerce, fulfilment, logistics or multi-tenant platforms
Experience building image-driven or asset-driven products
Familiarity with event-sourcing, DDD or service-oriented design
