Laufzeit: 01.03.2026 - 31.12.2026
Volumen: 600 Std. remote / 200 Std. onsite/ 20 Std. travel
Einsatzort: Remote / München

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

Project Description

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

Tasks

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

• 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
  and repeatable.
  
• Design and evolve the Ansible‑based infrastructure as code (roles, inventories, group variables) for OS base, container runtime,
  orchestration tooling, backend application(s) and databases across
  environments (DEV, TEST and PROD).
  
• Define and implement the setup for running the backend application and
  additional infrastructure components in a small on‑prem cluster,
  including job definitions, basic health checks and placement concepts
  supporting 1 Hz device read/write requirements.
  
• Design and operate secure configuration and secrets management using tools such as Ansible Vault, TLS and PKI concepts,
  ensuring credentials and keys for services and databases are handled
  safely.
  
• Set up and operate core data stores (e.g. InfluxDB v3, Postgres)
  for the lab/PoC and follow‑on environments, including backup/restore
  procedures and disaster recovery readiness.
  
• Integrate and operate the observability stack (e.g. Prometheus, Grafana, Alertmanager), ensuring visibility into the backend
  application, infrastructure components and 1 Hz read/write behavior.
  
• Collaborate with the Full‑Stack Developer and Solution
  Architect to align health endpoints, logging formats, metrics and
  deployment patterns.
  
• Contribute to the definition and implementation of CI/CD pipelines and operational processes with a clear governance model based on
  version -controlled automation.
  
• Produce and maintain infrastructure -level documentation (deployment guides, operations runbooks, backup/restore procedures,
  incident handling guidelines).
  

Required Skills &
Competencies

• Strong hands‑on experience as DevOps/Platform Engineer in on‑prem
  environments, ideally with data platforms or industrial/OT
  integrations.
  
• Solid skills in Ansible (or similar) for infrastructure as
  code: roles, inventories, group variables and automated provisioning.
  
• Practical experience with container orchestration tooling such as Nomad (or similar) for on‑prem deployments, including job specifications and
  rolling updates.
  
• Experience building and running containerised services using Docker,
  including multi‑stage builds and non‑root containers.
  
• Experience integrating observability stacks: Prometheus, Grafana, Alertmanager and centralised logging.
  
• Familiarity with time‑series and relational databases:
  e.g. InfluxDB and Postgres, including configuration and
  backup/restore.
  
• Experience implementing security and secrets management: Ansible
  Vault, TLS configuration and PKI concepts; familiarity
  with Keycloak or LDAP is a plus.
  
• Comfortable working in isolated on‑prem environments with
  limited or no direct internet connectivity.
  
• Ability to write clear technical documentation and runbooks.
  
• At least 3 years of experience in DevOps, platform engineering
  or infrastructure automation roles.
  
• Language: English (required), German (is a plus).
