RESEARCH DATA ENGINEER (INDIA) — SMALLEST.AI http://Smallest.ai

ABOUT THE ROLE

This is not a typical data engineering role. You won’t be building dashboards. You won’t be maintaining pipelines no one touches.

You will take messy, noisy, real-world data — and turn it into something models can learn from. Think of this as running a gold mine - you take dust and convert it to gold.

We work on speech, language, and real-time systems across 50+ languages. The difference between a good model and a great one is almost always data quality + data systems. That’s where you come in.

WHAT YOU’LL WORK ON

  • Data Pipelines (Real-time + Batch)
  • Build high-throughput pipelines for audio, text, and multimodal data
  • Streaming + offline processing at scale
  • Data Quality & Curation
  • Cleaning, filtering, deduplication, normalization (numbers, emails, code-mix, etc.)
  • Designing heuristics + ML-based data filtering systems
  • Multilingual Data Systems
  • Handling 50+ languages, accents, and code-mixed inputs
  • Language-aware normalization and segmentation
  • Training Data Engine
  • Build pipelines that continuously generate better training data from production
  • Active learning loops, data selection, sampling strategies
  • Evaluation & Benchmarking Pipelines
  • Create scalable eval datasets across languages and domains
  • Automate quality tracking for ASR, TTS, and conversational systems
  • Data Infra for Research
  • Work closely with research team to unblock experiments fast
  • Build systems that reduce iteration time from weeks → hours

WHAT THIS ROLE IS NOT

  • Not a dashboard/reporting role
  • Not a “move data from A to B” role
  • Not a maintenance-heavy legacy pipeline role

WHAT WE’RE LOOKING FOR

  • Strong fundamentals in data structures, systems, and pipelines
  • Experience with large-scale data processing (audio/text preferred)
  • Comfortable with messy, unstructured, real-world data
  • Strong coding skills (Python required; systems experience is a plus)
  • Understanding of ML/data pipelines (training, eval, data curation)

BONUS (NOT MANDATORY)

  • Experience with speech/audio data (ASR/TTS)
  • Familiarity with multilingual datasets
  • Experience with streaming systems (Kafka, etc.)
  • Exposure to data-centric AI / data quality frameworks

HOW WE WORK

  • Speed over perfection
  • Production over papers
  • Systems that scale, not scripts that barely work
  • Tight loop between data → model → eval → improvement

WHO THIS IS FOR

  • You enjoy working with raw, chaotic data
  • You care about data quality more than tooling hype
  • You like building systems that directly impact model performance
  • You get excited by turning unusable data into competitive advantage

WHY JOIN US

We’re building real-time, multilingual voice AI systems.

At this level, models are only as good as the data behind them.

If you want to work on the layer that actually moves the needle - this is it.
