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.
Technologies used: arc42, req42, tpo42, docToolchain, PlantUML, ArchiMate, C4 model, ADR, C, C++ (GTest), CMake, Bare Metal (ARM Cortex-M3/M7), OCI containers, Jenkins, lefthook, Prometheus, Grafana, SBOM, CRA, OPC, SCADA, PLC integration, IPv6 migration, Zero Trust, Sociocracy 3.0, Cynefin

About the technology
What a Bill of Materials is
A Bill of Materials, commonly called a BOM, is the structured list of components, materials, quantities and specifications required to make or maintain a product. It can describe a finished assembly, a subassembly, packaging, consumables or service parts. A reliable BOM gives production, procurement, quality and service teams a shared product definition.
BOM structures and uses
BOMs appear across mechanical, electrical, electronics, automotive, industrial equipment, medical and consumer product environments. The right structure depends on how a company designs, sources, builds and services its products.
- Engineering BOMs for design intent and product configuration
- Manufacturing BOMs for production planning and assembly
- Service BOMs for maintenance, spare parts and field support
- Sales and configurable BOMs for variants and customer orders
Systems and tooling
BOM specialists work across product lifecycle management, enterprise resource planning and manufacturing execution systems. They may handle CAD structures, item masters, effectivity dates, change notices and document links. Common work includes integrating systems, cleaning duplicate items and mapping engineering data into manufacturing-ready structures.
When companies need specialists
Companies often bring in freelance BOM expertise during product launches, ERP or PLM migrations, acquisitions, compliance work and manufacturing scale-up. Support is also valuable when engineering and operations use conflicting structures or when product variants are difficult to control.
- Resolve missing, duplicated or incorrectly linked components
- Define revision, approval and change-control workflows
- Align engineering, manufacturing and service BOMs
- Prepare data for migration, sourcing or contract manufacturing
Skills that matter
Strong professionals understand product configuration, item numbering, revision control, units of measure and engineering change management. They can read technical documentation and communicate with design, procurement, production and quality teams. Useful adjacent skills include CAD and PLM administration, ERP data management, SQL, integration mapping and master-data governance.
What good delivery looks like
Quality work produces complete, traceable and usable product structures rather than a spreadsheet that only works once. A specialist validates quantities, alternatives, revisions, dependencies and ownership with the teams using the data. They also document rules, test integrations and leave behind a maintainable process that supports future product changes.
Frequently asked questions
Need clarity? These are the questions we hear most often about Bill of Materials.
A Bill of Materials defines the components, materials, quantities and relationships needed to build, sell or service a product. Companies use BOMs for planning, purchasing, production, costing, quality control, maintenance and product change management.
An engineering BOM reflects how a product is designed and organized from a technical perspective. A manufacturing BOM restructures that information around how the product is assembled, including production steps, consumables, packaging and shop-floor requirements.
A Bill of Materials is product structure data, while ERP and PLM systems manage broader business or product lifecycle processes around that data. A BOM may be created in PLM, transferred to ERP and then used by manufacturing or service applications.
A strong BOM specialist may also understand CAD structures, PLM, ERP, item master data, revision control and engineering change orders. Experience with data migration, SQL, integrations and manufacturing processes is useful when the work spans several systems.
The required Bill of Materials experience depends on the scope, product complexity and number of connected systems. A basic cleanup may need focused data expertise, while a migration or multi-level configuration project calls for someone who has led comparable product-data and change-control work.
Yes, much Bill of Materials work can be completed remotely through shared PLM, ERP, CAD and documentation environments. On-site collaboration can still help during factory validation, process observation, workshops or hardware-specific assembly reviews.
Ask how the BOM professional validates structures, handles revisions, resolves duplicates and tests transfers between systems. Good candidates explain their controls clearly and can show how they improved traceability, usability and ownership without relying on undocumented spreadsheet workarounds.
A Bill of Materials can fail when item names, units, revisions or quantities are inconsistent across teams. Other common issues include missing subassemblies, duplicate parts, unclear effectivity, unmanaged alternatives and weak links between engineering and manufacturing data.
The average hourly rate of freelancers who have used Bill of Materials in their recent projects is 92 €, which corresponds to a daily rate of about 732 € based on an 8-hour working day.
