Project Description

o Implementation engagement to build the first on-prem installation based on the refined architecture and stepwise plan defined by the Solution Architect.

o Build a running single-node PoC on an on-prem server using containerised workloads, deployed and managed via infrastructure as code (e.g. using tools such as Docker and Ansible), with the option to introduce lightweight orchestration tooling (e.g. Nomad or a similar scheduler) as appropriate.

o Establish a reproducible, automated infrastructure and deployment model (IaC) for the backend application(s) and data stores, aligned with the architecture and on-prem constraints described in the use-case documentation.

o Implement secure secrets handling and TLS setups for external and internal traffic using tools such as Ansible Vault, in line with the platform’s security requirements.

o Integrate and configure the observability stack (e.g. Prometheus, Grafana, Alertmanager and a logging stack) so that the backend application, platform components and databases can be monitored and operated reliably.

o Support the evolution from the initial single-node PoC towards a small multi-node setup for the backend application and databases, keeping the system stable, maintainable and ready for future extension if additional components are introduced.

Job Description

The external consultant takes on the following tasks within the project, which are carried out independently:

o Take overall responsibility for the implementation of the on-prem infrastructure and deployment model (IaC) for the backend application, ensuring that all provisioning and deployments are automated, repeatable and aligned with a stepwise implementation plan.

o Design and evolve the Ansible-based infrastructure as code (roles, inventories, group variables) for OS base, container runtime, orchestration tooling (e.g. Nomad or a similar scheduler), the backend application(s) and databases across environments (DEV, TEST and later PROD), so that environment differences are expressed via code and configuration, not manual changes.

o Define and implement the setup for running the backend application and, where needed, additional infrastructure components in a small on-prem cluster (for example, from a single-node PoC evolving towards a small multi-node setup), including job definitions or deployment descriptors, basic health checks and placement concepts that support the platform’s 1 Hz device read/write requirements.

o Design and operate secure configuration and secrets management using tools such as Ansible Vault, TLS and PKI concepts, ensuring that credentials and keys for services, databases and device access are handled safely and in line with the architecture’s security assumptions.

o Set up and operate the core data stores (e.g. InfluxDB v3 or a comparable time-series database, and Postgres or a similar relational database) for the lab/PoC and follow-on environments, including backup/restore procedures, basic RPO/RTO targets and regular, documented restore tests to support disaster recovery readiness.

o Integrate and operate the observability stack (e.g. Prometheus, Grafana, Alertmanager and a logging solution), ensuring that metrics, logs and alerts provide sufficient visibility into the backend application(s), infrastructure components, databases and especially the continuous 1 Hz read/write behaviour of devices.

o Collaborate closely with the Full-Stack Developer and Solution Architect to align health endpoints, logging formats, metrics and deployment patterns so that the backend application(s) and frontend can be built, deployed and operated reliably in the target on-prem environment.

o Contribute to the definition and implementation of CI/CD pipelines and operational processes, with a clear governance model that routes all infrastructure and deployment changes through version-controlled automation (e.g. Ansible playbooks and related tooling).

o Produce and maintain infrastructure-level documentation (deployment guides, operations runbooks, backup/restore and disaster-recovery procedures, incident handling guidelines) and feed operational experience back into the evolution of the overall architecture and any future multi-site blueprint.

Conditions The consultant should be based within 100km of Essen and be available to work onsite at the client on request.

Skills

o Strong hands-on experience as DevOps/Platform Engineer in on-prem environments, ideally with data platforms or industrial/OT integrations.

o Solid skills in Ansible (or a similar configuration management tool) for infrastructure as code: roles, inventories, group variables and automating provisioning and application deployments on on-prem servers.

o Practical experience with container orchestration tooling such as Nomad (or a similar scheduler) for on-prem deployments, including job specifications, basic health checks and rolling updates.

o Experience building and running containerised services using Docker (or a comparable container runtime), including multi-stage builds, non-root containers and health checks.

o Experience integrating and using observability stacks: for example Prometheus (metrics), Grafana (dashboards), Alertmanager (alerts) and centralised logging.

o Familiarity with time-series and relational databases: e.g. InfluxDB (or an equivalent time-series store) and Postgres (or a similar relational database), including provisioning, configuration, backup/restore and basic performance considerations in on-prem setups.

o Experience implementing security and secrets management in on-prem environments: e.g. Ansible Vault (or a similar secrets management approach) for secrets, TLS configuration and PKI concepts; familiarity with identity providers such as Keycloak and LDAP/OpenLDAP integration is a plus.

o Comfortable working in isolated on-prem environments with limited or no direct internet connectivity and with lean local DevOps capacity.

o Ability to write clear technical documentation, runbooks and to collaborate effectively with architects, developers and internal operations teams.

o At least 3 years of experience in DevOps, platform engineering or infrastructure automation roles.

o Experience with on-premise deployments.

o Language: English, German is a plus.
