The user asked whether Citadel has a hybrid model. The JD is silent:
grepping the verbatim posting for hybrid, remote, onsite, in-office and
days per week returns zero matches. Phase 0 scored practical constraints
5/5 on an unexamined assumption that Zurich was workable. Withdrawn.
Ken Griffin is on record that Citadel returned to the office five days a
week, early and deliberately, and calls it his most important leadership
decision of the past seven years - framed as core apprenticeship culture
rather than a policy setting. The only contrary evidence is an anonymous
2022 Fishbowl post about Operations claiming three days minimum: four
years stale, wrong division, contradicted by the founder on record. No
official Citadel Securities Zurich policy statement could be found.
If five-day onsite holds for Zurich, it means roughly 2 to 2.5 hours of
commuting per day from Bern, or relocating - which breaks both the
Bern-based, 2-3 day hybrid bar in user_comp_bar and the "keep a Swiss
home base" constraint in user_international_mobility.
Practical constraints 5/5 -> 2/5 (language and authorization stay clean:
English working language, EU citizen, Swiss B permit). Evidence Fit
74 -> 71, still Adjacent but mid-band rather than a point below Core.
More consequential than the number: critique_framework.md treats an
unresolved location or relocation constraint as a NO-GO trigger, so the
qualifications gate passes while the practical gate does not. Phase 2 is
blocked pending an answer.
This has to be asked, not researched - the same class of question as the
SBB Anforderungsniveau K band. Recording the sequencing explicitly,
because SBB was submitted with its equivalent question still open and
that question is now a live screening topic instead of a settled fact.
Repeating it here should be a deliberate choice, not an oversight.
The Phase 1 bullet plan is written and unaffected: 11 recommended, 14
with options, budget PASS. Two items still open - the Vizrt VZ-1
C++/distributed bullet the user previously skipped on Snowflake, and
adding a Projects section for PP-1.

Evidence Fit 74/100, Adjacent at the top of the band, hard gate PASS
with one flagged risk. Phase 1 not started - user asked for Phase 0 only.
The stack alignment is the best in the log: zero Gaps across all seven
minimum qualifications, and all five preferred technologies (Kafka,
Kubernetes, Spark, Airflow, distributed databases) are Direct and
production-current.
What holds it at 74 is that the title-defining function splits. R2 -
ingestion, transformation, storage and lifecycle management of large
datasets - is Direct and describes SW-1/SW-7 almost word for word. R1 -
design and build the distributed research platform itself - is Adjacent,
the same authoring-vs-building shape as Aker BP, and it cannot be
written around: Scope Discipline forbids pairing a full-ownership verb
with an org-scale object, so it can only be honestly bridged.
Recorded the classification conflict rather than hiding it.
application_strategy.md says a defining responsibility that is only
Adjacent makes the role Stretch; that strict reading applies to R1. It
is filed as Adjacent because R2 is equally title-defining and is Direct,
and because Aker BP set that precedent at 79. Both cohort slots are free
either way, so the label changes nothing operationally.
Corrections the user was right about, now recorded so a later run does
not repeat them: Go is NOT a gap, because Q3 is disjunctive and Python
satisfies it outright; and a production Kafka/K8s/Spark/Airflow estate
IS a distributed system, so Q4 is Direct rather than a stretch.
Two traps written down explicitly. The $175,000-350,000 base range is a
US pay-transparency disclosure under NY law and says nothing about the
Zurich figure - it must be asked, not assumed. And the sibling reqs that
web search surfaces as closer title matches (Research Platform - Data
Platform Engineer, Research Platform Infrastructure Engineer) are dead:
404 and Cloudflare-blocked, absent from the live board. Those Built In
listings are stale.
JD saved verbatim via Playwright; WebFetch returns 403 on this host.
