Ground every answer in facts on this page and the original listing. We never invent Glassdoor-style reviews or salaries that are not in our data.
Expect scenarios on log/signal quality, false-positive tradeoffs, and how detections protect checkout, shopper, and retailer systems. Practice clear writeups of investigation steps and rule changes; O*NET-style safety tasks (accident investigation, hazard controls) are a weak match for this title—focus on security detection craft.
Strong fit if you enjoy threat detection on large consumer platforms and can partner across security and product. Weak fit if you want pure industrial EHS work or a clearly remote-only setup—this posting is U.S.-based with remote flagged off.
As a Detection Engineer II at Instacart, a typical day centers on building and tuning detections for threats against a high-volume grocery marketplace and shopper/customer platforms: reviewing alerts, refining rules and signals, investigating suspicious activity with security and product partners, and documenting findings so response stays fast as retail partners and delivery volume scale.
