Senior Cloud Network Engineer

Context & Mission

Vizzia is rapidly accelerating its growth and strengthening its network and cloud infrastructure to ensure a reliable, secure, and scalable platform. In this context, you will play a key role: ensuring the continuity and resilience critical network infrastructures, and taking automation to the next level.

The Challenge

20+ Terabytes per month. Thousands of concurrent VPN data streams. Exponential IoT fleet growth. Vizzia's IoT platform is scaling faster than our infrastructure We need someone who gets excited about solving problems at this scale. Not maintaining networks. Not just configuring routers. Building and automating the network infrastructure that powers a massive, high-growth IoT ecosystem.

What You'll Build & LearnInfrastructure Automation (Your Primary Focus)

• Automate everything: Build the IaC (Terraform/CDK) that turns network provisioning from hours into minutes

• Design network APIs: Create self-service automation that lets teams deploy infrastructure without manual intervention

• Scale with confidence: Build monitoring, alerting, and observability (Datadog) that catches issues before they become incidents

• Security from the ground up: Implement DevSecOps best practices, network hardening, and remediation at scale

Network Infrastructure at Scale

• Own the VPN architecture supporting thousands of concurrent device connections

• Design and evolve cloud network infrastructure (VPCs, routing, site-to-site connectivity) across AWS & GCP

• Bridge hardware and software: Work with Teltonika 5G routers, ensuring seamless integration with our platform

• Build for sovereign cloud: Navigate the unique challenges of secure, compliant cloud infrastructure (S3NS/GCP)

What Makes This Different

This isn't traditional network engineering. You'll spend more time writing Terraform and Python than touching router configs. More time building automation pipelines than troubleshooting VLANs. More time designing systems for scale than firefighting.

You will join a team that's a little obsessed with automating everything (and proud of it)

Your Profile

• Automation mindset: You think in code (Python/TypeScript) and IaC (Terraform/CDK). If you can't automate it, you're not done.

• Cloud networking fundamentals: Strong understanding of VPCs, subnets, routing, firewalls, site-to-site connectivity

• CI/CD experience: GitHub Actions or similar—automation includes your own deployment pipelines

• Ownership mentality: You don't wait for someone to tell you what to fix. You identify problems and solve them.

• Linux/Bash comfort: You're comfortable in terminal environments and shell scripting

• Docker proficiency: Containerization is second nature

• Professional proficiency in English

Bonus points (nice-to-have)

• Cloud certifications (AWS, GCP, or equivalent).

• Hands-on experience with VPN setup and management (OpenVPN / Netmaker)

• You've tamed container orchestration (Kubernetes or equivalent))

• Experience with observability tools beyond basic monitoring

• Background in high-scale network operations

What Will Make the Difference

• Strong autonomy: You own outcomes, not just tasks

• Clear communication: You can explain complex technical decisions to non-technical stakeholders

• Rigor and reliability: In a high-growth environment, details matter

• Problem-solving orientation: You navigate complexity and propose improvements proactively

• Documentation mindset: You share knowledge and build systems others can understand

Who This Role Is For

• Cloud/Platform engineers who want to specialize in network infrastructure automation

• DevOps engineers who love the networking domain and want to own it

What matters most: Automation mindset + systems thinking + ownership mentality. We'll invest in developing the rest.
