"Junior and mid-level engineers will now require more senior engineers to sign off any AI-assisted changes. AWS suffered a 13-hour interruption to a cost calculator used by customers in mid-December after engineers allowed the group's Kiro AI coding tool to make certain changes, and the AI tool opted to delete and recreate the environment."
"The FT previously reported multiple Amazon engineers said their business units had to deal with a higher number of Sev2s-incidents requiring a rapid response to avoid product outages-each day as a result of job cuts. Amazon has undertaken multiple rounds of lay-offs in recent years, most recently eliminating 16,000 corporate roles in January."
Amazon has tightened controls on AI-assisted coding following multiple service disruptions linked to its Kiro AI coding tool. Junior and mid-level engineers now require senior engineer sign-off for AI-assisted changes. AWS experienced a 13-hour outage in December when the AI tool deleted and recreated a cost calculator environment. A second incident also occurred but did not affect customer-facing services. Amazon characterized these as isolated events, though multiple engineers reported increased daily incidents requiring rapid response following recent workforce reductions. The company disputes claims that headcount cuts contributed to outage frequency.
