Build systems that manage thousands of time nodes in real-world 5G networks

Net Insight, are building building Zyntai — a distributed platform that keeps telecom networks precisely synchronized.

Today, the system supports roughly 2000 time nodes generating ~500,000 metric points per second, and the scale continues to grow. We’re looking for a Senior Cloud & Backend Engineer who wants to take ownership of complex systems and work close to both product and customers.

The role

You’ll join our Sync R&D organization (around 15 engineers) and be part of a team of 5 responsible for the backend platform behind Zyntai Director.

Your work will include:

• Building and extending backend services and APIs (Node.js / TypeScript)

• Designing systems that scale to larger distributed networks

• Improving performance and reliability in metrics-heavy systems

• Adding new capabilities such as IPv6 support

• Investigating customer-reported issues and production bugs

• Supporting customer PoCs together with Tech Sales

• Collaborating with product owners on upcoming features

Some days focus on feature development. Others on debugging real production issues. Both are core parts of the role.

Ownership and responsibilities

At Net Insight, there is no separate architecture department. Engineers are expected to take responsibility across the full lifecycle — from design and development to testing, troubleshooting, and continuous improvement.

You won’t just implement solutions — you’ll help define them.

Tech environment
You’ll work in a modern cloud-native environment including:

• Node.js / TypeScript

• Kubernetes

• AWS

• Distributed systems

• Observability and metrics-heavy platforms

• API and networking-related functionality

We are also investing heavily in AI-assisted development to improve both engineering workflows and future product capabilities.

How we work

We use Scrum/Kanban with daily standups and close collaboration across teams.

The Sync organization operates like a startup within the company, with tight cooperation between R&D, Product, Sales, and Tech Sales. Engineers are often close to customers, supporting PoCs and helping resolve real-world issues.

About you

You are likely a senior engineer who enjoys solving complex problems and taking ownership beyond your own code.

You probably have experience with:

• Backend development in production environments

• Distributed systems and scalability challenges

• Cloud platforms such as AWS, GCP, or Azure

• Designing reliable and maintainable systems

Experience with Kubernetes, networking concepts, or large-scale metrics systems is beneficial.

Why this role

This role offers:

• Real engineering challenges at scale

• Broad responsibility across design, development, and operations

• Close collaboration with customers and product teams

• A startup-like environment within an established company

• Small teams with meaningful ownership
