Job Summary

 At Qvantel, railway projects across Europe are on the rise, and our integration team needs to grow to keep up. The Qvantel Europe region is looking for a Railway Integration Engineer who thrives in a fast-moving environment, loves a complex challenge, and is hungry to learn new things. If that sounds like you, this is your chance to help deliver critical rail communication infrastructure. Due to the sensitivity of these projects, you must reside lawfully in an EU or NATO country. 

Railway operators are modernizing their communications and platforms: moving from traditional Bare Metal and appliance-based installations to containerized, cloud-native and hybrid deployments, while keeping GSM-R services dependable today and preparing for the transition towards FRMCS. If you are an experienced integration engineer who enjoys getting complex telecom solutions running reliably in real customer environments, whether on-premises or in a private cloud this role is for you. 

You will be someone who analyses problems methodically, communicates clearly with technical and non-technical stakeholders, stays calm under deadline pressure, and makes sound decisions with incomplete information. You will join a global telecommunications team delivering integration for complex BSS architectures. 

Key Responsibilities: 

• Deploy, integrate and test complex BSS architectures, on-site and remotely, across cloud-native (Kubernetes / OpenShift), hybrid and traditional VM or bare-metal environments, including internal products and the wider ecosystem of new or already installed applications 

• Configure the platform and GSM-R-specific services, and configure and validate interfaces to surrounding systems (e.g. SIGTRAN/SS7, REST/HTTP APIs) 

• Build and maintain deployment automation: container images and Helm charts, infrastructure as code, and CI/CD or GitOps pipelines to promote releases consistently across test, pre-production and production 

• Plan and execute migrations and cut-overs from legacy installations to cloud-native or hybrid platforms, including rollback planning and data migration 

• Be co-accountable for the operational launch of the solution, including observability (monitoring, logging, alerting), runbooks, and handover to customer operations 

• Be co-accountable for functional and non-functional testing of the deployed solution, including performance, high-availability, failover and disaster-recovery testing, supported by test automation 

• Troubleshoot across the full stack (application, container, platform, network and cloud infrastructure), and work with third parties, cloud providers and customer IT and security teams to resolve issues and ensure compliance with requirements 

• Contribute to technical documentation, deployment standards and knowledge sharing within the team 

Required Experience: 

• 5+ years of work experience with telco products and services 

• Hands-on experience with Red Hat Enterprise Linux and scripting (Bash and Python; Perl is a plus for maintaining legacy tooling) 

• Practical experience deploying and operating containerized applications with Docker and Kubernetes (OpenShift preferred), including Helm 

• Working knowledge of at least one cloud platform (AWS, Azure, Google Cloud or an equivalent private cloud) and of cloud networking, storage and security basics 

• Experience with CI/CD tooling and infrastructure-as-code (e.g. GitLab CI, Jenkins, Argo CD, Ansible, Terraform) 

• Understanding of the systems integration business, with experience in one or more aspects of telecom BSS solution deployment and integration 

• Ability to work proactively with minimal supervision, with excellent organizational skills 

• Strong customer and business focus, with a sound understanding of operator business drivers and technology 

• Strong analytical, critical-thinking and problem-solving skills 

• Excellent written and spoken English, including presentation skills 

Nice to Have: 

• Experience with Red Hat OpenShift operators, GitOps and service mesh or ingress configuration 

• Knowledge of mobile telecom networks (GSM) and of core networking and signaling technologies, including TCP/IP, SS7/SIGTRAN, Diameter, HTTP(S), TLS and REST/SOAP web services 

• Experience with observability stacks such as Prometheus, Grafana and the Elastic stack 

• Knowledge of cloud security practices: secrets management, IAM, certificate management, mTLS and network policies 

• Experience designing for resilience on cloud platforms (multi-zone or multi-site deployment, backup and disaster recovery) 

• Ability to write SQL queries to retrieve complex information from databases, and familiarity with cloud-native data stores 

• Test automation experience, including performance and resilience testing in containerized environments 

• Knowledge of Optiva Railway or OCE products 

• Knowledge of GSM-R fundamentals and standards (e.g. EIRENE, group and broadcast calls, eMLPP, functional addressing), and awareness of the evolution towards FRMCS 

• Experience configuring network elements such as switches, routers and load balancers 

• Right to work in the EU/EEA or UK 

Other Requirements: 

• Approx. 10-20% travel throughout the year can be expected, for customer sites and cut-over windows 

• Willingness to work flexibly around planned maintenance windows and go-live events, within agreed working-time rules 

• Maturity to adapt to different corporate and cultural environments 

• Fluent spoken and written English
