About Technology.

Technology at Huge is powered by a global practice of creative technologists—spanning Engineers, QA specialists, Business Analysts, Data Scientists, and ML Architects—we look beyond standard patterns to build resilient, enterprise-grade systems. We combine deep engineering rigor with innovation at the edge of agentic AI, modern data stacks, and cloud infrastructure. We don't wait for industry standards to set themselves; we engineer the intelligent systems that turn audacious strategic vision into production-ready reality.

The role.

Huge is looking for a Senior Software Engineer who loves building scalable distributed platforms. You will join a team of skilled engineers working on microservices, event integration patterns and data orchestration across hybrid cloud and on-premise environments. The projects are diverse, the clients are global and the work ships.

What you'll be doing.

Build high-throughput services with .NET 8+, C# and ASP.NET Core Minimal APIs across a distributed microservices architecture designed for mobile clients.
Design and implement scalable, asynchronous pipelines using message-bus patterns and distributed pub/sub frameworks to move real-time data between decoupled services.
Architect and own secure integration endpoints, including webhooks, event ingestion pipelines and third-party data feeds.
Shape data strategy across modern cloud storage and on-premise databases. You will own data modeling, query optimization, synchronization patterns and data integrity across NoSQL and SQL platforms.
Build and deploy in containerized environments such as Azure Container Apps and Kubernetes. Treat infrastructure as code as a core part of development and use application performance monitoring (APM) to keep services healthy and fast.
Spot architectural roadblocks and capability gaps in the hybrid ecosystem early. Offer alternatives such as caching strategies or API gateway optimizations to keep projects on schedule.
Partner with Strategy, Creative and Client leads to turn complex business requirements into clear, executable technical solutions for mobile apps.
Mentor the engineering team and set the standard for backend and platform best practices.
Stay current on the .NET and cloud-native ecosystem and advocate for tools and frameworks that improve system quality, scale and developer productivity.

What we'd like to see.

5+ years of hands-on experience with C#, .NET (Core/.NET 8+) and ASP.NET Core, building backend and distributed systems for high-concurrency applications.
Proven experience designing decoupled systems with event-driven communication patterns, including managing event flow, state and consistency in complex distributed environments.
Proven experience building production webhook systems, including signature verification, idempotency and retry logic, so third-party data flows stay fault-tolerant.
Proven experience with Entity Framework Core, Dapper, Azure SQL Server and Azure Cosmos DB.
Hands-on experience with container-first architecture and Azure services such as Event Hubs, Key Vault, Blob Storage and Managed Identity, plus the ability to manage the infrastructure-as-code deployment lifecycle.
Familiarity with APM platforms (Dynatrace, New Relic, Datadog) to diagnose bottlenecks, plus structured logging with Serilog and health check endpoints for service readiness.
Experience with defensive coding patterns and libraries like Polly, designing systems for graceful degradation and automatic recovery.
Skill with xUnit testing (e.g., Moq or NSubstitute and FluentAssertions). Experience with integration testing via WebApplicationFactory and security scanning tools (e.g., StackHawk, CodeQL) is a plus.
A strong appreciation for clean API design, with experience in OpenAPI and code generation tools (TypeSpec or similar) for consistent contracts across services.
The ability to explain complex technical trade-offs to non-technical stakeholders clearly, so technical constraints never get in the way of a great user experience.
