Extreme-Scale, Nano & Fundamental Engineering
/Trusted operator
Precision Engineering Engineer
Where tolerance, thermal drift and metrology decide whether a mechanism works at all.
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
Drive specific initiatives with minimal supervision. Deepen craft. Begin mentoring others.
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^-6 m to 10^0 m
A finite element result is only as good as its mesh, its material model and its boundary conditions, and all three are choices. This division reports a mesh convergence study with every structural result, states the material model used, and distinguishes a simulated part from a built one and a built one from a tested one. 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 D10: Mechanical, Robotics & Multi-Scale Systems. This division develops models across scales, translates material properties into system performance, runs engineering simulations, builds prototypes, and integrates advanced materials into working hardware. It is where the department's small-scale work becomes something a person can hold. This position: Where tolerance, thermal drift and metrology decide whether a mechanism works at all. Scale range for this work: 10^-6 m to 10^0 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.

Every opportunity states the kind of work it actually is. Level 4 (Specialist). The deep technical authority on a specific method or subsystem that other people depend on.
02 — The work
What you will own
- 01 Develop models that carry behaviour across scales, from a material property to a system response.
- 02 Translate material properties into system performance, and state where the translation loses accuracy.
- 03 Run engineering simulations with mesh convergence and material models recorded.
- 04 Build prototypes and test them against the specification they were designed to.
- 05 Integrate advanced materials from other divisions into working hardware.
- 06 Report the difference between what the model predicted and what the part did.
- 07 Hold the deep technical authority on a specific method or subsystem that other people depend on.
- 08 Make that method usable by others: documented, tested, and with its regime of validity written down.
03 — The expertise
What we look for
04 — The bar
Who thrives here
- → Education: Doctorate, or equivalent depth demonstrated through published or shipped work.
- → Experience: 4 to 7 years concentrated in one technical area, with demonstrable depth in it.
- → Scope of the role: The deep technical authority on a specific method or subsystem that other people depend on.
- → Must have: Can draw a free-body diagram for a real assembly and derive its governing equations. Also: Solid mechanics: stress, strain, failure criteria, and which criterion applies to which material.
- → 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.

Measured by
Objectives agreed at the start of each cycle. Hours recorded for compliance are never used as a performance score.
Where this stands legally
Within the 9-hour day and 48-hour week ceiling of the applicable state Shops and Establishments Act, with at least 24 consecutive hours of weekly rest and a break of at least 30 minutes after five hours of continuous work. Hours are recorded for statutory compliance only. Work beyond the scheduled week is agreed in advance and compensated with time off in lieu.

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
- Analyses with mesh convergence, material model and boundary conditions documented.
- Manufacturable designs with tolerances and a drawing that a shop can work from.
- Test reports comparing measured performance against predicted performance.
- A maturity statement per design: simulated, prototyped, or tested.
Evaluation criteria
- Whether mesh convergence was actually demonstrated.
- Whether the material model suits the loading regime.
- Whether the prototype was tested against its own specification.
- Honesty about the gap between prediction and measurement.
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.
