Full job description

The Role

Are you a senior backend engineer who thrives on distributed systems, clean architecture, and complex data problems? At ONYX Insight, we're looking for a Senior Software Developer (Contractor) to make an immediate impact on our core platform, a sophisticated distributed system processing data from wind turbines around the world.

This is not a typical SaaS CRUD role. You'll work across a distributed architecture including asynchronous messaging, worker processes, and data ingestion pipelines.

Frontend exposure is a bonus, not a requirement.

Key Responsibilities:

Backend Delivery: Implement robust, well-tested C# .NET services following clean architecture principles — domain logic, data access, messaging, and background processing.

Distributed Systems: Contribute to service boundary design, asynchronous messaging flows, and worker processes within our modular monolith, with an eye on future decomposition.

Data Pipelines: Build and maintain backend ingestion flows that sanitise, standardise, and process high-volume sensor data reliably and at scale.

Code Quality: Write clean, well-tested code with strong unit and integration coverage. You care about correctness, not just delivery.

Collaboration & Deployment: Support frontend engineers with clean API contracts, and contribute to our CI/CD pipeline and artifact-based deployment process.

Ideally, you'll have/be:

Deep, commercial C# .NET experience (5+ years) — comfortable with clean architecture, SOLID principles, and building maintainable systems at scale.

Solid experience with distributed systems and async patterns — service buses, message queues, background workers, and event-driven architecture. You understand the tradeoffs, not just the tooling.

Experience building data ingestion or processing pipelines — handling high-volume, real-world data with a focus on reliability and fault tolerance.

Strong PostgreSQL skills — schema design, migrations, and efficient queries against complex data models.

A genuine testing culture — unit and integration tests written as standard, with an understanding of what makes a test suite valuable.

Familiarity with AWS and how backend services are deployed and monitored in production.

Experience with modular or service-oriented architectures — you appreciate well-defined boundaries and can work pragmatically within a monorepo.

A contractor mindset: self-directed, fast to ramp up, and able to deliver independently — while communicating clearly when things need to be challenged.

Some React or TypeScript exposure is useful, but frontend delivery is not an expectation of this role.
