Senior Control Systems Engineer

Net Insight is a pioneering technology company within media networks, resource optimization and time synchronization. Their Zyntai

solution is used to distribute highly accurate time in critical 5G and network infrastructure — with nanosecond-level precision

and without relying on GNSS.

We are now looking for a senior engineer with deep knowledge of automatic control, estimation, signal processing and mathematical

modelling — combined with strong software engineering skills in modern C++ and Python.

This is not a general C++ role. It is a role for someone who wants to work close to the core algorithms, understand the underlying

control problem, and turn advanced theory into robust production software.

You will join a highly technical team working with a modern product, senior colleagues and complex real-world engineering

challenges.

Zyntai provides critical infrastructure, such as 5G base stations, with extremely accurate time synchronization. A Zyntai network

consists of hundreds or thousands of TimeNodes that continuously exchange time information and measurements.

The system uses this data to estimate network and oscillator behavior and to control the local clock in each node. This requires

advanced algorithms within control theory, estimation, filtering, signal processing and mathematical optimization.

You will work in the team responsible for the core synchronization functionality in Zyntai. The team develops the algorithms and

software used to process measurement data, estimate system behavior and control the oscillator in each TimeNode.

You will work with methods such as Kalman filtering, Model Predictive Control, PI/PID controllers, state estimation, signal

processing and mathematical optimization.

Most implementation is done in modern C++ in the TimeNodes. Python is used for modelling, analysis, tooling, testing and

development in Zyntai Director, Net Insight’s Kubernetes-based orchestration system for managing TimeNodes.

You need to be comfortable moving between theory and implementation: from mathematical reasoning and control system design to

production-quality software in a distributed system.

We are looking for a senior engineer who combines strong knowledge within control systems with the ability to build high-quality

software.

You probably enjoy understanding the underlying system — not just the codebase. You like mathematical and algorithmic challenges,

and you are comfortable discussing control loops, estimation, stability, filtering, optimization and real-world system behavior.

You do not need to have worked with time synchronization before, but you need strong experience from automatic control, applied

mathematics, signal processing, robotics, cybernetics, telecom, industrial systems or similar areas.
