Extreme-Scale, Nano & Fundamental Engineering
/Individual contributor at the frontier
Senior Particle Physicist
Several analyses at once, and the statistical judgement applied to all of them.
Compensation
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
Own complex problems end-to-end. Set technical direction. Mentor mid and junior teammates.
Research classification
Computing quantities that cannot be obtained in closed form, from established physics. Reproducible calculations, convergence and error budgets, released code and datasets.
Computational research. Computed from established physics. A computed number is a prediction, and it is only as good as its convergence, its error budget, and whatever data it can be checked against.
Scale range 10^-18 m to 10^-12 m
This is the smallest scale anything has actually been measured at, and the measurement is statistical. Results here are distributions with uncertainties, not single numbers, and a result quoted without its uncertainty is not a result. We analyse public and collaboration datasets; we do not operate accelerator facilities and do not claim to. Scientific integrity is a condition of every role in this department. Assumptions are stated separately from conclusions. Uncertainty is reported. Negative and inconclusive results are written up, not discarded. Speculative work is labelled speculative, including when that makes it less impressive. Fabrication, falsification, and presenting a simulation as a measurement end an engagement here.
Scale bands are a research classification, not a claim of experimental reach. Most of this span cannot be probed by any apparatus that exists: nothing below about 10^-19 m has been measured directly, and anything at 10^26 m or beyond is inferred from observation rather than engineered. Every opportunity states the kind of work it actually is.
01 — The role
Why this role exists at EduRankAI
Department of Extreme-Scale, Nano & Fundamental Engineering, Division D02: Particle, High-Energy & Nuclear Systems. This division works where theory meets very large datasets. It builds simulation pipelines, analyses public and collaboration datasets, quantifies uncertainty honestly, and supports detector and materials research with computation. It does not operate an accelerator. This position: Several analyses at once, and the statistical judgement applied to all of them. Scale range for this work: 10^-18 m to 10^-12 m. Research classification: Computational. Computing quantities that cannot be obtained in closed form, from established physics. Evidential standing: Computational research. Computed from established physics. A computed number is a prediction, and it is only as good as its convergence, its error budget, and whatever data it can be checked against. This is the smallest scale anything has actually been measured at, and the measurement is statistical. Results here are distributions with uncertainties, not single numbers, and a result quoted without its uncertainty is not a result. We analyse public and collaboration datasets; we do not operate accelerator facilities and do not claim to. Scale bands are a research classification, not a claim of experimental reach. Most of this span cannot be probed by any apparatus that exists: nothing below about 10^-19 m has been measured directly, and anything at 10^26 m or beyond is inferred from observation rather than engineered. Every opportunity states the kind of work it actually is. Level 5 (Senior). Several related problems at once, and the technical judgement of less experienced colleagues.
02 — The work
What you will own
- 01 Model particle and nuclear interactions and compare the models against measured distributions.
- 02 Analyse public and collaboration datasets, with the selection criteria written down before the result is looked at.
- 03 Build and maintain simulation pipelines that run reproducibly at scale.
- 04 Quantify statistical and systematic uncertainty separately, and report both.
- 05 Validate computational results against known cases before trusting them on unknown ones.
- 06 Support detector and radiation-damage research with modelling other divisions can use.
- 07 Carry several related problems at once without losing the thread of any of them.
- 08 Raise the technical judgement of less experienced colleagues, in review and in person.
03 — The expertise
What we look for
04 — The bar
Who thrives here
- → Education: Doctorate or an equivalent research record.
- → Experience: 6 to 10 years, including work that other people have built on.
- → Scope of the role: Several related problems at once, and the technical judgement of less experienced colleagues.
- → Must have: Can state what a cross-section is, in what units, and how it relates to an event rate. Also: Has written a Monte Carlo simulation and can explain its variance and how it was reduced.
- → Portfolio: at least one piece of work — code, a written result, a thesis chapter, a preprint — that somebody outside your institution can read and assess. It does not need to be published.
Terms of Engagement
How working time works at this level
No counted hours. A five-day week with a four-hour overlap window so colleagues can reach you, and objectives agreed for the cycle.

Measured by
Objectives agreed for the cycle, the quality of the judgement calls, and the people the work makes better. Not attendance.
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.
05 — Hiring process
What to expect after you apply
- 01
Application review
Every application is read personally within five business days. We respond either way.
- 02
Take-home or live exercise
Role-specific. Time-boxed. Real problems we are actually working on, not invented puzzles.
- 03
Conversations
Deep technical and values conversations with the team you would join. No trick questions. No panel ambushes.
- 04
Offer or honest no
If yes: digital offer letter, signed in-portal, transparent terms. If no: written feedback if you want it.
The standard
What you deliver, and how it is judged
Deliverables
- Analysis code with a fixed environment, a recorded selection, and a seeded run.
- Distributions and fits reported with statistical and systematic uncertainties separated.
- Validation notes showing the pipeline reproducing a known result before it was used on a new one.
- Simulation configurations another division can run without asking how.
Evaluation criteria
- Whether the uncertainty budget is complete and defensible.
- Reproducibility of the analysis from a clean checkout.
- Validation against a known benchmark before any novel claim.
- Resistance to the temptation to tune a selection after seeing the result.
Preferred, not required
Nothing in this list is a bar to applying.

Our situation
EduRankAI is a small, independent organization building long-term capabilities in educational intelligence, advanced AI systems, and research infrastructure. We take no advertiser money, no donations with strings attached, and no investor pressure on hiring decisions. Applying is free, and every application is read by a human — recruitment, technical, academic and leadership teams. It buys us the right to be honest.
Ready to apply?
We read every application personally. If you are the right person for this role — regardless of pedigree, background, or where you are based — you will hear back from us within five business days.
Apply through this page. You will be asked for your education, your experience, and links to work we can actually read — a repository, a write-up, a thesis chapter, a preprint. Send the piece of work you would defend, not the one with the best title. If a result in it turned out to be wrong, say so; we would rather read that than not know. Every application is read by a person. We assess applications on evidence of the work. We do not filter on institution, on age, on gender, on caste, on religion, on disability, or on where you are from. If any part of this process is inaccessible to you, tell us and we will change it for you.
