(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.
