About the role

Data Labeling Specialist (Machine Learning)

We are looking for a detail-oriented and methodical Data Labeling Specialist to support the development of machine learning models.

You will play a crucial role in preparing high-quality, accurately labeled datasets that train and validate our AI systems used for interpreting engineering diagrams, process data, and industrial information models.

This position is ideal for someone with strong attention to detail, patience, and a passion for working with structured and visual data.

Responsibilities:

• Accurately label and annotate visual and textual data (e.g., symbols, equipment, lines, and relationships) used to train ML models.
• Work closely with ML engineers to understand labeling guidelines, edge cases, and model requirements.
• Follow established labeling protocols and ontology structures to maintain consistency across datasets.
• Review, validate, and perform quality control on labeled datasets to ensure accuracy and completeness.
• Identify and report data quality issues or ambiguities in source data and propose improvements.
• Use internal or third-party annotation tools (e.g., CVAT, Label Studio, SuperAnnotate) to perform labeling tasks.
• Maintain detailed documentation of labeling processes and contribute to continuous improvement of annotation standards.
• Maintain detailed documentation of labeling decisions, conventions, and exceptions to ensure reproducibility and consistency
• Contribute to continuous improvement of labelling accuracy, tooling, and overall dataset quality

Required Skills

• Hands-on experience interpreting P&ID diagrams either through previous roles in data labeling, engineering support, drafting, or technical documentation.
• Familiarity with ISA/ISO P&ID standards (e.g., ISA-5.1, ISO 14617).
• Ability to identify and categorize P&ID components consistently, including instrument loops, signal lines, and control systems.
• Understanding of process flow and interconnections can infer functional relationships between components.

Preferred Skills

Deep familiarity with P&ID structures and industrial system logic.

• Can help define and refine labeling guidelines and ontologies used for ML training.
• Experience working with engineering data standards or digital twin systems.
• Comfortable liaising with ML engineers and process engineers to ensure annotations reflect real-world process semantics.

Additionally required abilities:

• Strong attention to detail ability to spot small inconsistencies or edge cases.
• Discipline and patience can perform repetitive tasks with accuracy.
• Clear communication able to describe ambiguities or propose annotation improvements.
• Collaborative mindset works effectively with ML engineers and domain experts.
• Process-oriented thinking appreciates guidelines, consistency, and versioning of labeled data.
