Jens R.
Last position:
Platform Architect & Senior Developer at Direct client, industrial measurement technology, medium-sized company
- Technical leadership across hardware, firmware, and software teams; scope: hardware/firmware team (4 people) and leadership group (5 people)
- Consolidated and documented a product family that had grown over more than 15 years and aligned it with CRA compliance — from the bare-metal I/O module to the cloud interface.
- Provided the most important customer product with the essential requirements and architecture documentation within two months — for a firmware landscape that had grown over more than 15 years. It now supports the customer’s modernization strategy.
- Established a monthly reporting line to the supervisory board and executive board within three months: nine meetings since 12/2025. The report itself is versioned and built from the CI pipeline; it is based on automatically collected activity and release data instead of assessments.
- Built a container-based CI/CD infrastructure from scratch: cross-compilation, host tests, and documentation builds in one continuous pipeline.
- Introduced declarative QA gates for DevOps and development artifacts — from the start using lefthook instead of pre-commit, executed in a dedicated container image.

About the technology
What it is
A Bill of Materials is a structured record of the components, materials, quantities and production relationships that make up a product. Often called a BOM, it can describe a finished assembly, a subassembly, packaging or service parts. Accurate BOM data gives teams a shared product definition from design through manufacturing and support.
Where it is used
BOMs support product development, sourcing, manufacturing, maintenance and after-sales operations. Companies use them to control product variants, plan material requirements and keep technical and commercial data aligned.
- Engineering and manufacturing BOM structures
- Configurable products and variant management
- Spare-parts and service BOMs
- Change-controlled product releases
Ecosystem and tooling
BOM work often spans CAD and mechanical design systems, PLM, ERP and supply-chain applications. Specialists may work with multi-level structures, effectivity dates, units of measure, item revisions and approved manufacturer parts. They also connect BOM data with change management, document control and procurement processes.
Common delivery formats include structured exports, import templates, APIs and reports. The right approach depends on whether the company needs an engineering view, a manufacturing view or a service view of the same product.
When expertise matters
Freelance expertise is useful when product data is inconsistent, a new ERP or PLM system is being introduced, or an acquisition has created several item and component standards. It is also valuable before a product launch, a factory transition or a major redesign.
- Harmonising item numbers, units and naming conventions
- Mapping engineering BOMs to manufacturing BOMs
- Migrating structures between CAD, PLM and ERP systems
- Defining ownership, approvals and change workflows
What strong specialists deliver
Strong professionals start by clarifying the product model, source systems and decisions the BOM must support. They distinguish revisions from variants, preserve traceability and document rules that internal teams can maintain. Their deliverables may include cleansed structures, migration mappings, validation checks, governance guidance and practical user documentation.
They also test realistic assemblies instead of relying only on sample data. This exposes missing components, duplicate items, invalid relationships and workflow gaps before the information reaches purchasing or production.
Working in Cologne
Companies in Cologne and the surrounding region can need BOM expertise for industrial products, automotive supply chains, medical equipment, electronics or complex machinery. On-site workshops can help when teams must align engineering, production and procurement, while remote collaboration works well for data analysis, mapping and documentation. Clear English or German communication should be agreed at the start, especially when terminology is shared across locations.
Frequently asked questions
Curious about Bill of Materials? Here are the answers that come up again and again.
A Bill of Materials defines the components, materials, quantities and relationships required for a product or assembly. Companies use BOMs to support design, procurement, production, service and cost control while keeping product changes traceable.
A BOM is more than a simple parts list because it can include hierarchy, quantities, revisions, effectivity and approved alternatives. A product structure usually describes how items relate, while a BOM is often managed for a specific engineering, manufacturing or service purpose.
A strong Bill of Materials specialist usually understands PLM, ERP, CAD data, change control and item master governance. Experience with data migration, variant configuration, manufacturing processes and procurement makes the work more useful across departments.
The required BOM experience depends on the product complexity, source systems and quality of the existing data. A straightforward structure cleanup may need focused data expertise, while a global migration or configurable product model calls for a professional who has handled governance, integrations and adoption.
Yes, Bill of Materials work can often be done remotely through secure system access, workshops and structured data reviews. On-site sessions in Cologne may still help when engineering, manufacturing and procurement teams need to agree on ownership or validate physical assemblies.
Ask a BOM expert to explain how they would handle revisions, variants, duplicates, missing links and conflicting source data. Strong professionals can show a clear validation method, traceability approach and handover plan rather than focusing only on data loading.
An engineering BOM reflects how a product is designed and its functional components, while a manufacturing BOM describes what production needs to assemble it. A Bill of Materials professional should know how to relate both views without losing revisions, quantities or change history.
Before engaging a Bill of Materials freelancer, collect sample structures, system names, item and revision rules, known data problems and the intended business outcome. In Cologne-based projects, also clarify whether workshops require German, English or both and which activities must happen on-site.
