- Read / write models and optimised queries for high-volume mileage calculations.
Sensor & Telematics Integration
- Integrated telemetry and sensor processing pipelines.
- Snapshot and state-calculation logic for sensor systems.
- APIs and persistence models for wagon sensor data; data-quality improvements.
- Further development of a service using gRPC for intra-service communication.
Movement Segment Processing & Routing
- Migrated services to new movement-segment event streams.
- Built replay and rebuild tooling for segment correction.
- Optimised throughput and reliability for high-volume event processing.
Condition Monitoring & Wagon Analytics
- APIs and backend services for wagon condition monitoring.
- Brake-wear prediction processing and wagon analytics functionality.

About the technology
Pipeline automation
Concourse CI is an open-source automation system for continuous integration and delivery. It models work as pipelines made of jobs, resources and plans, making dependencies and execution steps visible in configuration. Companies use it to build, test, package and release software through repeatable workflows.
Core concepts
Concourse CI treats inputs and outputs as versioned resources. Jobs run tasks in isolated containers, while workers provide the execution capacity and teams control access through roles and targets. Strong specialists understand pipeline YAML, resource checks, task containers, credentials and the Fly command-line tool.
Ecosystem and tooling
Concourse CI connects with Git repositories, container registries, artifact stores, cloud services and deployment tools. Specialists often work with Docker or OCI images, Kubernetes, Terraform, Vault, Prometheus and cloud identity systems. They also structure shared task definitions, custom resource types and reusable pipeline patterns.
When expertise helps
Companies bring in freelance expertise when delivery workflows have become difficult to maintain, releases need stronger controls or a migration from another automation system is planned.
- Design pipelines for build, test and release stages
- Improve worker capacity, caching and resource management
- Connect secrets, registries, approvals and deployment targets
- Migrate pipelines while preserving traceability and access rules
Delivery in Germany
Teams in Germany use Concourse CI across software products, industrial systems, automotive supply chains and regulated environments. Freelance specialists can work remotely with repositories, runners and documentation, or collaborate on site when infrastructure access and close coordination require it. Clear communication in English or German should be agreed early.
Quality indicators
A strong Concourse CI professional makes pipelines readable, reproducible and easy to diagnose. They separate configuration from secrets, define reliable resource versions and keep tasks small enough to test independently. They also explain worker topology, failure handling, permissions and operational ownership instead of treating the pipeline as isolated YAML.
Frequently asked questions
Key details about Concourse CI, drawn from the questions we get asked most.
Concourse CI is used to automate software integration and delivery through declarative pipelines. Companies use it for source checkout, automated tests, container builds, artifact publication and controlled deployments.
Concourse CI emphasizes explicit pipelines, versioned resources and containerized tasks. Jenkins offers a broad plugin ecosystem, while GitHub Actions is closely tied to GitHub; the right choice depends on governance, hosting, integrations and the level of workflow transparency required.
A strong Concourse CI specialist usually understands Git, Docker or OCI images, Linux, YAML and test automation. Experience with Kubernetes, Terraform, Vault, cloud identity, container registries and observability is also valuable when pipelines operate across distributed environments.
The required depth depends on the scope. A simple pipeline may need focused configuration skills, while a shared platform requires expertise in worker pools, permissions, secrets, resource behavior, upgrades and incident diagnosis. Ask for examples that resemble your delivery model rather than relying on a generic career history.
Yes. Concourse CI is well suited to remote collaboration when repositories, infrastructure access, runbooks and communication channels are organized. On-site work can still help with protected environments, internal controls or workshops, and teams should agree on English or German as the working language.
Review whether the pipelines are reproducible, readable and easy to troubleshoot. A capable Concourse CI professional can explain resource versions, task isolation, worker placement, secret handling, failure recovery and how changes are tested safely.
In Concourse CI, resources represent versioned inputs or outputs such as Git repositories, images and artifacts. Jobs define work and dependencies, while tasks describe commands that run in isolated containers; together they form the pipeline's execution model.
Concourse CI fits teams that value declarative configuration, visible dependencies and consistent containerized execution. It is especially useful when pipelines must coordinate repositories, build outputs, approvals and deployments across environments, provided the team is ready to operate its workers and integrations.
