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.

ABOUT THE ROLE We are seeking a hands-on, technically fluent engineer to drive the adoption of AI across our entire development organization - someone who finds the friction in how teams work and turns it into automated, AI-powered solutions. As our AI Enablement Engineer, you will embed with engineering and product teams to identify where AI can remove repetitive, manual work, then build and ship the solutions that make it happen. You will work closely with our AI Efficiency Architects and AI Evangelist to turn high-level AI strategy into concrete, measurable wins on the ground. This role is ideal for someone who enjoys variety, moves fast, and gets real satisfaction from seeing their work adopted and relied upon by teams across the company. Your Mission Accelerate how the entire development organization works by finding high-impact use cases for AI, building the solutions that automate them, and spreading those wins so they scale across teams. YOU WILL BE RESPONSIBLE FOR: Use Case Discovery: work directly with engineering and product teams to map their workflows, spot repetitive or slow processes, and identify the highest-impact opportunities for AI-driven automation across the development organization. Rapid Prototyping & Delivery: act as a builder - lead the technical design and implementation of working solutions such as prompt workflows, lightweight agents, scripts, and integrations that prove value fast, then partnering with the AI Efficiency Architects to harden anything that needs to run in production. Reusable Enablement Assets: create templates, playbooks, and repeatable patterns so a proven AI win can spread from one team to many without bespoke work each time. Adoption & Measurement: drive genuine adoption of AI tooling across teams and tie every solution back to concrete outcomes - time saved, throughput, and delivery speed - so impact is visible and quantifiable to leadership. Feedback to the Platform: surface recurring needs and friction back to the AI Efficiency Architects, so the internal AI gateway and tooling evolve toward what teams actually need. Technical Mentorship & Influence: mentor senior engineers on AI best practices and influence engineering roadmaps. OUR SUCCESSFUL CANDIDATE WILL HAVE THE FOLLOWING: ESSENTIAL SKILLS Staff-Level Engineering Foundations: 8+ years of professional software engineering experience (Java, Python, Go, or TypeScript) with a proven track record of delivering complex, distributed systems in a production environment. Production-Ready AI Expertise: Deep, hands-on experience moving AI from a cool prototype to a real-world tool. You don’t just write basic prompts - you know how to build reliable agents and RAG workflows, and you understand the practical side of LLMs, like managing costs, speed, and context limits to make tools actually work for production. Strategic Problem-Solving: You have a strong bias for action and can take a vague problem and turn it into a working solution fast. While you focus on delivering value quickly rather than chasing perfection, you always think big - building smart, reusable tools that fix root problems for hundreds of developers, not just one team. Collaboration & Communication: excellent interpersonal skills and the ability to work alongside many different teams, understand their needs, and bring them along on the adoption journey. SDLC/DevOps Familiarity: working knowledge of the tools that underpin the software delivery lifecycle (e.g., GitLab/GitHub, CI/CD pipelines, source control) so that solutions fit naturally into how teams already work. Self-Direction: capacity to manage a varied portfolio of work across multiple teams, prioritize for impact, and deliver with minimal supervision.
