As a

Senior

Software Engineer, you will design, build, deploy, and operate production systems that power IREN’s AI services and platform infrastructure. This full-lifecycle engineering role involves independently owning services from API definition and backend implementation through Kubernetes deployment, observability, and production operations. You will work across service boundaries—writing application code, improving platform tooling, and debugging live systems in production. This role is ideal for engineers comfortable operating across backend systems, distributed infrastructure, and cloud-native platforms, and who take responsibility for the reliability and performance of the systems they build. Job Requirements

End-to-End Software Ownership Design, implement, and operate production software systems from initial design through long-term maintenance. Own services across environments (local, pre-prod, and production), including deployment via GitOps workflows (e.g., ArgoCD). Make pragmatic architectural decisions that balance performance, reliability, and maintainability. Take responsibility for production health, on‑call participation, and continuous improvement of owned systems. Backend & Service Engineering Build high-performance backend services and APIs supporting multi-tenant, distributed workloads. Design and evolve API‑first interfaces (REST and/or gRPC), including schema design, versioning, and client integration. Implement reliable inter‑service communication patterns, including retries, backpressure, idempotency, and message processing. Integrate with data stores, message queues, and streaming systems as required by application workflows. Platform & Cloud-Native Deployment Deploy and operate services on Kubernetes using modern cloud-native practices. Define and maintain infrastructure using Infrastructure-as-Code (Terraform or equivalent). Work within CI/CD pipelines to enable safe, repeatable builds and deployments. Reliability, Performance & Observability Instrument services with metrics, logs, and tracing to ensure operational visibility. Diagnose and resolve issues across application, infrastructure, and networking layers. Participate in incident response, root‑cause analysis, and post‑incident improvements. Continuously improve system performance, scalability, and resource efficiency. Job Responsibilities

Technical Skills 5+ years of experience building and operating production software systems. Strong proficiency in at least one systems or backend language (Go, Python, Rust, Node). Solid understanding of distributed systems fundamentals (concurrency, consistency, fault tolerance). Experience building and operating API-driven services (REST, gRPC). Hands‑on experience deploying services to Kubernetes. Familiarity with Infrastructure-as-Code tools such as Terraform. Experience with cloud platforms (AWS, GCP) and core services (compute, networking, IAM). Working knowledge of observability practices and tooling (metrics, logging, tracing). Soft Skills & Engineering Mindset Comfortable owning problems end-to-end with minimal oversight. Clear communicator who works effectively across engineering, platform, and infrastructure teams. Pragmatic decision‑maker who values operational simplicity and reliability. Curious and adaptable, with a willingness to learn new technologies and domains. Strong sense of accountability for production systems. Bonus Qualifications Exposure to AI systems, LLM tooling, vector databases, or inference serving. Experience with Kusto-based storage and query layers. Jinja-based templating and generation workflows. Grafana visualization, Prometheus and experience with time‑series databases. Job Benefits
