After outages, Amazon to make senior engineers sign off on AI-assisted changes

Operational meeting and new sign‑off policy
Amazon has instructed staff to attend its weekly “TWiST” operations meeting, which is normally optional.
Junior and mid‑level engineers will now need senior engineers to sign off on any AI‑assisted changes, according to Treadwell.
Amazon said the review of website availability was “part of normal business” and that it aims for continual improvement.
“TWiST is our regular weekly operations meeting with a specific group of retail technology leaders and teams where we review operational performance across our store,” the company said.
AWS AI‑assistant incidents
Amazon Web Services (AWS) has experienced at least two incidents linked to the use of AI coding assistants that the company has been rolling out to staff.
- In mid‑December, AWS suffered a 13‑hour interruption to a cost calculator used by customers after engineers allowed the group’s Kiro AI coding tool to make certain changes. The AI tool chose to “delete and recreate the environment,” as reported by the FT.
- Amazon previously described the December incident as an “extremely limited event” affecting only a single service in parts of mainland China. The company added that the second incident did not impact a “customer‑facing AWS service.”
Layoffs and outage claims
The FT previously reported that multiple Amazon engineers said their business units had to handle a higher number of “Sev2s”—incidents requiring rapid response to avoid product outages—each day as a result of job cuts.
Amazon has undertaken several rounds of layoffs in recent years, most recently eliminating 16,000 corporate roles in January. The company disputes the claim that headcount cuts were responsible for an increase in recent outages.
