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.
A world leader in media networks, resource optimization and synchronization technology
Work with advanced control algorithms in a real-world, large-scale product
A highly technical environment with modern tools and senior colleagues
Open and flat organization with strong teamwork and knowledge sharing
Family-friendly company with flexible working hours
Unusually low turnover and high employee satisfaction
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.
The core challenge is to distribute time over complex networks with extremely high accuracy — without depending on GNSS.

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.
Deep knowledge of automatic control, control theory or cybernetics
Practical experience from designing, analysing, tuning or implementing control algorithms
Strong mathematical foundation within estimation, filtering, optimization, statistics, signal processing or dynamic systems
Experience from methods such as Kalman filtering, MPC, PI/PID, observers, state estimation or system identification
Strong software engineering skills in modern C++, preferably C++20/23
Good Python skills
Experience from Linux-based development
Ability to turn complex algorithms into robust, maintainable production code
Time synchronization, PTP, NTP, SyncE or GNSS-independent systems
Distributed or networked systems
TCP/IP and network communication
Kubernetes or cloud-native systems
Real-time or near-real-time systems
Graph theory, statistics or mathematical optimization
Telecom, 5G, industrial systems or robotics
This role is a great fit if you want to work where mathematics, control systems and software engineering meet.
