About The Position

Alloy is hiring a Senior IT Security Engineer to own workforce identity and access management, from access grants and automation through reviews and removal. The role is the primary technical expert for Okta, SaaS access, and identity automation, while also sharing responsibility for broader IT and Security work in a shared-SME and backup-coverage model. Alloy's customers are banks and fintechs, and its ISO 27001 and SOC 2 programs rely on access controls that withstand audits. The position is hybrid and requires in-person office attendance four days per week: Tuesday through Thursday, plus either Monday or Friday. The engineer participates in the IT and Security on-call rotation to respond to critical alerts and urgent after-hours support requests.

Strong troubleshooting, documentation, and communication skills in a shared-responsibility IT/Security team.
