Job Description:

My client is on a mission to simplify complex delivery infrastructure—and they’ve built a next-generation SaaS platform that’s now scaling internationally. With UK launch already complete and a US rollout underway, they’re tackling big engineering challenges and delivering powerful tech at serious scale.

They’re now looking for a highly skilled server-side C# engineer to join their lean, senior-led engineering team—working on a platform that’s pushing boundaries in event-driven architecture, distributed systems, and customer-first delivery.

What You’ll Work On:

• A greenfield microservices platform (24+ services) built around CQRS, Event Sourcing, and DDD
• High throughput transactional systems processing tens of thousands of requests per hour
• Real-time tracking and customer self-service layers designed to minimise support tickets
• A technically mature, agile team where every developer contributes to architectural direction

Tech Snapshot (and What You Must Know Cold):

• C#/.NET: ~8 years commercial server-side experience, ideally across multiple codebases and domains
• → You’ll also mentor and train other engineers—this is a hands-on leadership opportunity
• Event Sourcing & DDD: Not just academic—you must have commercial experience implementing, supporting, and evolving these patterns in production
• Messaging Tech: Proficiency in at least one asynchronous message-based system (e.g., RabbitMQ, Azure Service Bus, Kafka, etc.)

What You'll Bring:

• A test-first, craft-focused engineering mindset
• Strong architectural instincts with a collaborative, debate-positive attitude
• Comfort with modern engineering workflows and continuous delivery

Why You’ll Love It:

• Interesting problems: This isn’t CRUD—think event sourcing at scale, complex routing logic, and fast data decisions
• Input into architecture: Every engineer is involved in shaping how the system evolves
• Relaxed, mature setup: No clock-watching—just flexible hours and a team of adults who love great code
• Modern stack: Real-world use of cutting-edge tools—not just theory
