Job description

We are seeking a Backend Software Engineer to lead our workflow orchestration, SDK modernization, and microservices initiatives. In this role, you will build automated workflows using Google Cloud Composer (Apache Airflow), construct high-performance services with FastAPI, and deploy cloud-native solutions across GCP (Cloud Run, Cloud Functions).

If you excel at building scalable data pipelines, writing custom Airflow operators, containerizing apps with Docker, and integrating BigQuery with Cloud Dataflow, we’d love to connect.

The Impact You’ll Make (Key Responsibilities)

• Workflow Orchestration & Pipelines: Serve as the core backend specialist leading the design, implementation, and optimization of end-to-end data pipelines and workflow orchestration using Google Cloud Composer (Apache Airflow).
• SDK & Application Modernization: Drive software engineering initiatives to facilitate the seamless transition, integration, and continuous upgrade of application SDKs and core microservices across client ecosystems.
• Python Engineering: Deep hands‑on experience architecting production‑grade Python applications, writing complex Airflow workflows/custom plugins, and building high-performance asynchronous microservices with FastAPI.
• Cloud Architecture (GCP): Proven experience building cloud-native architectures on Google Cloud Platform, with expertise in Cloud Composer, Cloud Functions, Cloud Run, and containerization via Docker.
• Data Integration: Interface backend microservices and orchestration workflows with BigQuery, Cloud Dataflow, and Pub/Sub to process, manage, and transform large-scale data sets.
• DevOps & Release Engineering: Maintain robust Git-based CI/CD workflows for automated pipeline deployment, zero‑downtime SDK releases, and seamless backend updates.

What You Bring to the Table (Requirements)

• 5+ years of experience in backend software engineering, data orchestration, and microservices architecture.
• Strong hands‑on expertise with Google Cloud Composer / Apache Airflow, including workflow authoring, dynamic task generation, custom operators, and pipeline management.
• Mastery of Python 3.x, asynchronous programming, and modern frameworks (e.g., FastAPI, AsyncIO).
• Strong GCP foundation with hands‑on experience across Cloud Composer, Cloud Run and Cloud Functions.
• Direct experience integrating microservices and orchestrated workflows with data pipelines, BigQuery, and Cloud Dataflow.
• Robust containerization skills using Docker for container creation, optimization, and deployment.
• Proven track record in SDK management, including API/SDK design, versioning, and seamless client integration.
• Proficiency in DevOps & CI/CD tools (Git, GitHub Actions, Cloud Build) for continuous deployment of code and orchestration workflows.
• Commitment to software quality through rigorous testing frameworks like pytest and automated integration tests.

The Market Advantage (Preferred Qualifications)

• Advanced Airflow/Composer Mastery: Experience managing enterprise‑grade Airflow clusters, performance tuning, and building modular workflow frameworks.
• GCP Certifications: Google Cloud Certified Professional Data Engineer, Cloud Developer, or Cloud Architect.
• SDK Publishing Experience: Practical experience publishing, versioning, and maintaining public or internal open‑source SDK packages (e.g., PyPI packages).
• Enterprise Modernization: Hands‑on experience modernizing legacy batch or monolithic systems into scalable, event‑driven, and orchestrated cloud microservices.
• Stream Processing: Deep familiarity with Apache Beam, Pub/Sub, or Kafka for real‑time and event‑driven data architectures.
• Security & Compliance: Familiarity with API and workflow security standards (OAuth2, OIDC, IAM, secret management, zero‑trust frameworks).
• Education: Bachelor’s or Master’s degree in Computer Science, Software Engineering, or a related field.

The Aviato Edge (Why Partner With Us?)

• Ex-Google Pedigree: Work side‑by‑side with engineers and founders who built their careers at Google, operating within a zero‑politics, high‑IQ environment.
• True Hybrid Autonomy: We trust you to \"make good choices\" regarding your workspace—collaborate seamlessly from your home in Victoria, checking in on‑site with clients in Melbourne when milestones demand.
