About Redrob

Redrob is a Series A blitzscaling startup building the Android to ChatGPT's iPhone - creating accessible, application-layer LLMs that democratize AI for businesses and professionals worldwide. With $14M in funding from top-tier investors (including early backers of SpaceX and Lyft) and the South Korean government, we're on a mission to bridge the technology gap between developed and emerging markets.

Our global presence spans Seoul, New Delhi, Mumbai, and New York, positioning us at the forefront of making AI economically viable for every individual worldwide.

The Role

We're seeking a
data engineer who bridges software, MLOps, and infrastructure
, passionate about supporting real-world AI products. You should enjoy working hands-on with data pipelines, large-scale AWS services, and machine learning environments.

You'll be working directly with the
AI Engineering Team
driving the Redrob LLM roadmap, and together you'll shape the backbone that feeds our fine-tuned AI systems and deliver a production-ready model.

What You'll Do

• Design and implement scalable data pipelines
  on AWS to ingest, clean, and transform structured and unstructured HR/Sales datasets (e.g., CRM exports, chat logs, resumes, support tickets).
• Develop and manage data lake architecture
  using AWS S3, Glue Catalog, Athena, and Redshift to support model training, analytics, and evaluation workflows.
• Integrate directly with SageMaker
  — building preprocessing pipelines, training data manifests, and calibration datasets for distillation, quantization, and fine-tuning.
• Automate ETL and data validation
  with Glue, Lambda, or Step Functions to enforce schema integrity and ensure JSONL compliance for instruction-tuning datasets.
• Implement robust data governance and lineage tracking
  using SageMaker Lineage, Glue Data Catalog, and LakeFS or MLflow for reproducibility and auditability.
• Optimize data workflows for performance and cost
  through Spot usage, S3 Select, and Glue job tuning.
• Ensure security and compliance
  with enterprise-grade controls — IAM roles, KMS encryption, private VPC endpoints, and data access monitoring via CloudWatch.
• Collaborate cross-functionally
  with AI, backend, and DevOps teams to integrate high-quality datasets into LLM training pipelines and downstream APIs.

Requirements

• 1+ years of experience in
  data engineering
  or
  ML data infrastructure
  .
• Strong proficiency in
  Python
  (Pandas, PySpark, or Dask).
• Deep knowledge of
  AWS services
  like S3, Glue, Athena, Redshift, Step Functions, Lambda, IAM, and KMS.
• Experience designing
  ETL pipelines
  using Airflow, Glue Workflows, or Step Functions.
• Familiarity with
  SageMaker Processing and Training
  workflows (data ingestion, manifests, and job orchestration).
• Strong SQL and data modeling skills for analytical and ML workloads.
• Experience implementing
  data versioning and lineage tracking
  (LakeFS, DVC, MLflow, or similar).
• Solid understanding of
  data security, encryption, and access management
  within AWS environments.
• Must be authorized to work in the United States (we cannot sponsor work visas at this time)

What We Offer

• Base Compensation:
  $100,000 - $120,000 USD
• Benefits:
  Comprehensive health, dental, and vision insurance
