Job Description

About Trideca

Trideca is Australia's trusted strategy, AI, and digital transformation partner - helping some of the nation's largest enterprises (including NAB, Suncorp, Optus, Medibank, and AGL) drive meaningful business impact through technology.

With offices in Melbourne and Sydney and projects spanning multiple industries, we thrive on solving complex challenges, delivering cutting-edge solutions, and pushing the boundaries of what's possible.

About role

We are working exclusively with a major Australian health insurance organisation to find a sharp, performance-minded .NET engineer who can hit the ground running on a critical enterprise integration programme. This is a pure delivery role — you'll be building high-performance, fault-tolerant integration pipelines connecting enterprise platforms at scale, backed by a strong Engineering Lead and Senior Developer who own architecture so you can focus entirely on execution.

What makes this different

No architectural overhead. No admin. The lead team handles design decisions — your mandate is to pick up well-defined tasks and ship production-quality .NET code with precision and velocity. If you're a "gun developer" who thrives on clean execution, this was built for you.

What You'll Be Doing

• Building and optimising NET-based integration pipelines using RESTful APIs and asynchronous webhook architectures across a complex enterprise ecosystem
• Writing resource-efficient, enterprise-grade code — memory-conscious, CPU-optimised, and performant under high load
• Implementing concurrency and parallelism patterns (async/await, TPL, multi-threading) to safely handle large-batch data processing
• Building self-healing, fault-tolerant pipelines — retries, circuit breakers, exponential back-off — because there is no human operator in the loop
• Working with message brokers and event-driven architecture (Azure Service Bus, RabbitMQ, or Kafka) to decouple and scale processing
• Applying TDD and SOLID principles to keep the integration codebase modular, testable, and regression-free
• Connecting to enterprise platforms including Salesforce, Dynamics, SailPoint, and Entra ID (prior exposure helpful but not required)

Skills We're Looking For

Essential

• NET Core / C# — .NET Core / .NET 8+, C#, modern async patterns — 3+ years professional experience
• Concurrency & Parallelism — TPL, multi-threading, async/await — real production examples, no race conditions
• Fault Tolerance — circuit breakers, retries, exponential back-off, idempotent resumable pipelines
• Messaging / Event-Driven — Azure Service Bus, RabbitMQ, or Kafka — at least one in production
• API & Webhooks — RESTful API design, high-volume async webhooks, deduplication, failure handling
• TDD & SOLID — Test-Driven Development in practice — high coverage, modular, maintainable code

Desirable

• Enterprise Platform Experience — Salesforce, Dynamics, SailPoint, Entra ID — or any comparable CRM / IAM platform
• Cloud / DevOps — Azure (preferred), AWS or GCP — Docker, Kubernetes, Azure Functions, YAML config

The Team & Environment

• You'll sit alongside an Engineering Lead and a Senior Developer — architectural decisions are theirs, execution is yours
• Enterprise-scale engagement at a well-known Australian organisation — complex, modern, and technically challenging
• A team that is committed to zero-friction delivery — if you hit a blocker, the lead team steps in; your job is to ship

The Right Fit

• You have worked in complex, enterprise-scale environments — not just SMB or greenfield projects
• You can articulate your approach to concurrency and fault tolerance from first principles — not by citing AI or frameworks
• You raise concerns during planning; once a task is committed, you deliver without re-litigating
