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
The most senior individual contributor at the company. Not a manager. You set technical direction across teams without owning headcount, and the architecture documents you author are the ones other engineers will reference for years. The point of this role is to be the engineer that other senior engineers trust to think hard about something nobody has time for. You will spend a third of your time deep in the hardest production failures, a third writing the RFCs that bind multiple teams, and a third mentoring Staff-tier ICs into Principal candidates.
02 — The work
What you will own
- 01 Set cross-cutting technical direction across product, platform, and AI.
- 02 Author architecture RFCs that bind multiple teams for 12-24 month horizons.
- 03 Mentor Staff and Senior engineers; bring at least one Staff engineer to Principal-ready over 24 months.
- 04 Dive into the hardest production failures and fix them at root, then write the institutional learning.
- 05 Own one or two cross-cutting systems end-to-end (deploy infra, observability stack, secrets, etc.).
- 06 Be the second pair of eyes on every org-wide technical decision the CTO makes.
03 — The expertise
What we look for
04 — The bar
Who thrives here
- → You have been the senior-most IC at a company or org for at least 2 years.
- → You have authored an architecture document that bound multiple teams and survived contact with reality for at least 12 months.
- → You can describe an outage you root-caused that nobody else on your team could have.
- → You write internal essays without being asked to.
- → You have publicly disagreed with senior leadership in writing at least once, professionally, and survived 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.
