Extreme-Scale, Nano & Fundamental Engineering
/Senior leadership
Principal Infrastructure Engineer
The division's technical direction and the hardest problems in resilient large-scale systems.
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
Set direction within your domain. Build and mentor a team. Own outcomes at the function level.
Research classification
Engineering to a specification, on established science, for something that has to work. Designs, analyses against requirements, test evidence, and maintainable engineering artefacts.
Established science. Rests on settled physics and engineering. The work applies it; it is not what is under test here.
Scale range 10^0 m to 10^6 m
Structural work touches public safety, and this division does not blur the line between research and practice. Nothing produced here is a design certification. Any structure that will be built is designed, checked and stamped under the applicable code by a licensed engineer, and our analyses are inputs to that process rather than a substitute for it. 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 D11: Civil, Structural & Macro-Scale Systems. This division applies advanced materials to infrastructure, models structural behaviour, builds infrastructure digital twins, develops resilient systems, and integrates sensing and analysis. Anything that could bear on public safety is treated as regulated engineering, not as research output. This position: The division's technical direction and the hardest problems in resilient large-scale systems. Scale range for this work: 10^0 m to 10^6 m. Research classification: Applied engineering. Engineering to a specification, on established science, for something that has to work. Evidential standing: Established science. Rests on settled physics and engineering. The work applies it; it is not what is under test here. Structural work touches public safety, and this division does not blur the line between research and practice.

Every opportunity states the kind of work it actually is. Level 7 (Principal). Technical direction across divisions, and the hardest open problems the department holds.
02 — The work
What you will own
- 01 Apply advanced materials from other divisions to infrastructure problems, with the durability question asked first.
- 02 Model structural behaviour, including the load cases that are not the design case.
- 03 Build infrastructure digital twins and state what each twin does not represent.
- 04 Develop resilient systems against stated hazards rather than against a general aspiration.
- 05 Integrate sensing and analysis into structures, including what the sensors cannot see.
- 06 Name the point at which a piece of work becomes regulated design, and hand it over.
- 07 Take on the hardest open problems the department holds, including the ones that may not resolve.
- 08 Set the technical standard that other people's work is measured against, and defend it.
- 09 Represent the department's scientific position accurately outside it.
03 — The expertise
What we look for
04 — The bar
Who thrives here
- → Education: Doctorate or an equivalent research record.
- → Experience: 10 or more years, with results that changed how a technical area is approached.
- → Scope of the role: Technical direction across divisions, and the hardest open problems the department holds.
- → Must have: Can analyse a statically indeterminate structure and check the result by an independent method. Also: Structural analysis: load paths, limit states, and why a code has both.
- → 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, plus responsibility for the coverage of your area — including who is on call and when.

Measured by
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.
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
- Structural analyses with load cases, code references, and an independent check.
- Digital twins with a written statement of scope and known blind spots.
- Monitoring designs including the failure modes the instrumentation would miss.
- Clear handover notes where work crosses into licensed design.
Evaluation criteria
- Whether the analysis was independently checked.
- Whether the load cases include the ones that are not convenient.
- Whether the regulatory boundary was respected without being asked.
- Usefulness of the twin to somebody operating the actual asset.
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.
