Systems & Applications Engineer

A European leader in B2B connectivity. From 0G to 5G, we're not just in the game, we're reinventing it. With our roots deep in B2B, Citymesh offers top-tier 4G/5G networks and innovative WiFi-as-a-service solutions. Are you ready to elevate your career within a telecom pioneer that's reshaping the industry?

Here’s what you’ll dive into:

For our Solutions Engineering & Development team we’re looking for a Systems and Applications Engineer. Joining this development engine of the company, you will engage in full stack development from bare metal to application layer, and in particular, anything in between. You will help design and build a scalable edge application framework, define deployment strategies, and drive lifecycle management across every layer of the solution. Beyond the platform itself, you will play a pivotal role in bringing mission critical applications to our customers on top of this scalable and automated platform (e.g., push to talk systems at ports and airports, where uptime and security are non-negotiable).

This is a hands‑on engineering role with a strong architectural flavor. If you love the challenge of turning complex infrastructure into clean, automated, and reproducible platforms - capable of running in the most demanding operational environments - this role is for you.

Your job in a nutshell:

Design and build a scalable edge-application framework, including deployment strategies and end-to-end lifecycle management at server, hypervisor, orchestration, and application level.

Define and implement infrastructure automation: provisioning, configuration management, orchestration and continuous delivery pipelines for edge deployments.

Evaluate and select hypervisor and container orchestration technologies to support multi‑tenant, high‑availability workloads in constrained environments.

Define and implement the approach to deliver (mission‑critical) applications on this edge application framework in a scalable and secure manner.

Collaborate closely with the rest of the multidisciplinary engineering and development team, as well as the solution managers, to translate operational requirements into neatly integrated end‑to‑end solutions. In the case of Citymesh, our applications will run on mission critical networks, so affinity with network engineering, and speaking the same language as our network architects will be a major plus.

Define hardening, patching, and security policies for the stack you own.

Contribute to the Citymesh product portfolio by identifying new use-cases and evaluating emerging technologies in edge computing and application orchestration.

These are your talents:

You hold a master’s degree in Computer Science or a related field. Recent graduates are also encouraged to apply.

A good understanding of system architecture is important. This includes bare-metal servers, system sizing, hypervisors and container runtimes. Experience with Kubernetes, Docker or similar tools is an asset.

Infrastructure automation interests you. CI/CD pipelines and configuration management tools, such as Ansible, are familiar territory.

Experience with observability and monitoring tools, such as Prometheus and Grafana, is a plus. Knowledge of edge computing platforms is also considered an asset.

You understand the fundamentals of networking or are eager to further develop your knowledge in this area. Familiarity with real‑time application stacks, such as push‑to‑talk and VoIP, is a strong advantage.

An entrepreneurial, proactive and independent mindset comes naturally to you. Technical challenges are handled with ownership and followed through from start to finish.

Fluency in Dutch and English is required. Knowledge of French is a plus.

What do we offer?

At Citymesh you will be part of an enthusiastic and ambitious team in which we greatly value your own input and believe in the growth of each of our employees.
