Staff ML Engineer — Applied

Applied ML & Agents

Lead Full-Time On-site — Kolkata, West Bengal, India Permanent

Compensation

INR 45 - 75 LPA

Engagement

Full-Time

Permanent role. Full-time commitment. This is an on-site role at Kolkata. It is not remote and not hybrid.

Scope of role

Set direction within your domain. Build and mentor a team. Own outcomes at the function level.

01 — The role

Why this role exists at EduRankAI

Take our foundation models and turn them into product. Agents, retrieval, tools, evals, structured output. You are the bridge between the research lab and what users actually see inside AquinTutor, the AI tutor, the proctoring assistant. The role exists because most "LLM features" fail in production not because the model is wrong, but because the surrounding system is sloppy — bad retrieval, fragile prompts, no evals, no fallback. You will fix that, and you will train the rest of the team in how to.

02 — The work

What you will own

  • 01 Build agents and tool-using systems on top of our LLMs.
  • 02 Design retrieval and grounding pipelines that actually work at production scale.
  • 03 Author the applied-ML eval harness; make it the place we discover regressions before users do.
  • 04 Ship LLM features inside AquinTutor, the AI tutor, the proctoring assistant.
  • 05 Lead the prompt engineering and system-prompt design practice.
  • 06 Mentor mid and senior ML engineers; bring at least one to Senior readiness over 18 months.

03 — The expertise

What we look for

LLM agents, function calling, tool useRAG architectures, embedding models, vector DBsStructured output (constrained decoding, JSON mode, grammars)PyTorch / transformers at production depthStrong product instinctsEval-driven development discipline

04 — The bar

Who thrives here

  • You have shipped at least two LLM-backed product features that survived contact with real users for 6+ months.
  • You can describe a specific LLM regression you caught with an eval that you wrote yourself.
  • You write better prompts than the people you work with — and you can teach them why.
  • You have read enough agent literature to have an opinion about what does and does not work.
  • You write code that you would be comfortable showing in a code review at Anthropic or DeepMind.

The outcomes of the area you lead, the reliability of its coverage, and the growth of the people in it.

Where this stands legally

Hours are not counted at this level. The statutory ceiling of 9 hours a day and 48 a week remains the limit the role is designed to fit inside: if the work cannot be done within a normal week, the scope is wrong, not the person.

The full per-level model is published at Working Hours by Level.
