About The Role We’re looking for a Principal Backend Engineer to take a key role in shaping the architecture and technical direction of our platform.

You’ll design systems that handle millions of transactions, improve performance across services, and ensure our technology can scale safely and efficiently as the business grows.

You’ll act as a technical leader and hands-on architect, guiding teams, raising the quality bar, and helping us make smart, sustainable engineering decisions.

What You’ll Be Doing

• Architect the future: design, implement, and evolve distributed systems that handle high throughput and millions of concurrent transactions. • Provide technical leadership: act as a go-to expert for backend and infrastructure topics, mentoring teams and raising the overall engineering bar. • Optimize performance: identify bottlenecks and design scalable solutions that improve availability, latency, and cost efficiency. • Drive reliability: establish solid standards for monitoring, alerting, and incident management, ensuring our systems are observable and resilient. • Collaborate across teams: partner with product and business leaders to translate ideas into clear technical strategies and execution plans. • Improve continuously: challenge existing solutions, propose better patterns, and keep us aligned with modern practices in distributed systems and DevOps. • Lead by example: write clean, maintainable code; review peers’ work; and ensure consistent engineering quality across services. • Be part of on-call rotations for critical systems, focusing on root-cause prevention, not firefighting.

Tech Stack You’ll work with a modern, cloud-native environment including:

• Languages & Frameworks: C#, .NET 8, .NET Core • Messaging & Streaming: Kafka, RabbitMQ, Azure Service Bus • Databases: SQL Server, MongoDB, CosmosDB, Redis • Infrastructure & Orchestration: Docker, Kubernetes (AKS), Azure Cloud • Monitoring & Observability: Grafana, Kibana, Application Insights

Experience with this exact stack is not mandatory, but deep technical curiosity, sound design principles, and adaptability are.
