Senior Software Developer (Back-end Focus)

About Evie Networks
At Evie, we are powering the future of transport by building and operating Australia's largest public EV fast-charging network. Our digital ecosystem connects hardware, cloud infrastructure, energy management systems, and partner networks to give electric vehicle drivers total confidence on the road.
As our network grows rapidly, we are looking for a Senior Software Developer (Back-end Focus) who brings a blend of hands-on technical excellence, architectural oversight, and technology leadership to anchor our core back-end engineering function.
The Opportunity
This is more than a standard engineering position - it is a critical leadership role within our digital ecosystem.
Reporting directly to the Chief Product Officer, you will be responsible for the architectural integrity, scalability, and 99.9% high-availability uptime of the back-end services, APIs, and cloud infrastructure that underpin our charging network.
What You'll Do (Key Responsibilities)

• Back-end Architecture & Engineering: Design, build, and scale critical back-end microservices and event-driven architectures using Node.js and TypeScript.
• API & Roaming Orchestration: Build secure, high-performance public/private APIs and integrations with key charging partners.
• Data & Cloud Infrastructure: Own MongoDB schema design, indexing, and query optimization, while deploying resilient services on Kubernetes and Google Cloud Platform (GCP).
• Hardware-Software Integration: Bridge cloud back-ends with embedded IoT hardware and charging station firmware.
• High-Availability Operations: Ensure 99.9% uptime across production environments, managing automated failover protocols, release integrity, and observability (logging, metrics, alerting).
• People Leadership & Mentorship: Conduct 1:1s, performance reviews, goal setting, and technical code reviews to upskill direct reports and mid-level developers.
• Security & Governance: Implement advanced security protocols aligned with ISO 27001, Australian Privacy Principles, PCI DSS, and industry standards (OCPP/OCPI).

• 5+ Years' Software Experience: Substantial time dedicated to back-end development in production environments.
• Core Tech Stack: Proven expertise in Node.js, TypeScript, and distributed, event-driven microservices architectures.
• Data & Cloud Mastery: Deep experience with MongoDB (or NoSQL alternatives), Kubernetes, containerization, CI/CD pipelines, and GCP (or equivalent cloud provider).
• High Availability: Demonstrated success maintaining 99.9%+ system uptime and managing production release integrity.
• People Management: Direct experience managing at least 1-3 engineers, including performance reviews, 1:1s, and technical mentorship.
• Modern Developer Workflow: Confident user of AI-assisted tools (e.g., Claude Code, GitHub Copilot) as a core part of your daily workflow.
• Security & Privacy: Solid understanding of API security, data privacy, and governance principles.

• Working knowledge of OCPP 1.6/2.0.1 and OCPI EV standards.
• Prior exposure to EV charging systems, IoT hardware integration, or energy management systems.
• Experience with Infrastructure-as-Code (Terraform/Pulumi) and contract testing.
• Hands-on experience with observability stacks (e.g., Datadog, Grafana, OpenTelemetry).

• Meaningful Impact: Help accelerate Australia's transition to sustainable energy and build infrastructure that directly reduces carbon emissions.
• Technical Ownership: Own critical back-end services end-to-end-from initial architecture to production deployment and operational monitoring.
• Flexible & Inclusive Culture: We support hybrid working arrangements and assess every candidate purely on merit in an open, inclusive environment.
