(Data & ML Platform) - Technical Interviewer

Intetics Inc. is a leading American technology company providing custom software application development, distributed professional teams creation, software product quality assessment, and “all-things-digital” solutions, is looking for Technical Interviewers.

Expert Profile Overview

The technical expert should have hands-on experience designing and operating large-scale data / ML platforms, ideally in medical imaging or regulated environments. They must be able to evaluate both implementation-level skills and system-level decision-making, with a strong focus on traceability, compliance, and production readiness.

Areas of Expertise Required

Data & ML Platform Architecture

• Experience building end-to-end data platforms spanning on-prem infrastructure and AWS.

• Ability to assess architectural decisions related to scalability, fault tolerance, cost optimization, and data lineage.

• Understanding of how to design systems that are FDA-ready by design, not retrofitted.

Medical Imaging & Ingestion Pipelines

• Strong familiarity with DICOM, PACS workflows, and tools such as Orthanc.

• Ability to assess ingestion and QC strategies for:

• CT imaging

• Video and C-Arm data

• Radiology reports

• Understanding of data validation, normalization, and failure handling in clinical pipelines.

Distributed Processing & AWS

• Hands-on experience with AWS Batch, preferably with Spot instances.

• Ability to evaluate candidate knowledge of:

• Job orchestration

• Cost-aware scaling

• Idempotency and retries

• Large-scale batch QC and inference workloads

• General AWS proficiency (S3, IAM, networking concepts).

Dataset Versioning & Experiment Tracking

• Practical experience with ClearML or comparable tools.

• Ability to assess:

• Dataset lineage and provenance

• Experiment reproducibility

• Artifact and metric tracking

• Understanding of how these capabilities support regulatory audits.

Training Data Access & Storage Optimization

• Experience with Lance or equivalent high-performance data access layers.

• Ability to evaluate candidate approaches to:

• Fast data loading for training

• Incremental dataset updates

• Decoupling raw media from derived data

Metadata, Labels & Search

• Strong understanding of PostgreSQL-based services for metadata, labels, and predictions.

• Ability to assess database schema design for traceability and auditability.

• Familiarity with OpenSearch (text/vector) as a plus.

Labeling Workflows

• Experience integrating labeling platforms (Encord preferred).

• Ability to evaluate candidate understanding of:

• RBAC and access control

• QC and review workflows

• Audit trails

• Algorithmic label ingestion and updates

Regulated Environments & Compliance

• Solid understanding of 21 CFR Part 11 expectations:

• Access control

• Audit trails

• WORM storage

• Data provenance

• Experience working with HIPAA / PHI-regulated data.

• Ability to identify compliance gaps in proposed architectures.

Interview Responsibilities

The technical expert will be expected to:

• Participate in technical interviews (system design + deep dive).

• Ask scenario-based questions focused on real production and regulatory challenges.

• Evaluate candidate answers for:

• Practical experience vs. theoretical knowledge

• Trade-off awareness

• Risk identification and mitigation

• Review take-home tasks or architectural diagrams if applicable.

• Provide clear, structured written feedback with a hire / no-hire recommendation.

Ideal Background of the Expert

• Senior / Principal Data Engineer, ML Platform Engineer, or MLOps Engineer.

• Prior experience in healthcare, medical imaging, or regulated ML systems is strongly preferred.

• Comfortable challenging candidates and defending technical decisions in front of stakeholders.
