Senior IT Platform Engineer Beast Industries · San Mateo, CA (on-site 4 days/week at Step) · Full-time · Reports to the Director of IT Identity & Application Lifecycle ABOUT THE ROLE Beast Industries is the company behind MrBeast, Feastables, Beast Games, and a growing family of businesses that now includes Step, the fintech platform helping the next generation build credit and manage money. We're unifying identity across that whole family. Hundreds of SaaS applications and hundreds of employees are converging onto a single Okta instance while regulated, compliance-sensitive systems stay properly isolated. You'll be the engineer working deep inside that platform. You'll know how users and applications get onboarded, provisioned, secured, and retired across every Beast company, and you'll run point for Step. That means the HRIS-driven provisioning that feeds it, the SSO and SCIM integrations for its app stack, and the dual-instance boundary that keeps its regulated systems separate from the rest of the business. This is a hands-on engineering role, not an administrator seat. You'll think in APIs, scripts, and pipelines, and you'll build automation so lifecycle events run themselves. You'll also anchor the West Coast for the Beast IT team, working from Step's San Mateo office about four days a week. The office runs on you being there. You're the face of IT for the region, the first call when something breaks, and the person who makes sure exec visits and events go off without a hitch. WHAT YOU'LL DO Identity platform engineering Run the user lifecycle end to end. Design and operate automated joiner, mover, and leaver flows for new hires, department changes, contractors, rehires, offboarding, and MFA enrollment, driven by HRIS events across multiple payroll and HR platforms. Drive the application lifecycle. Onboard, integrate, maintain, and decommission apps across an inventory of several hundred SaaS applications, dozens of them federated for SSO and SCIM coverage growing, including our multi-workspace Slack environment. SAML, SCIM, and SWA configurations are your daily work. Engineer identity automation. Manage groups, group rules, and sign-on and authentication policies, and build the automation that keeps them honest. Work fluently within the dual-instance architecture that isolates regulated fintech systems like KYC, brokerage, and banking integrations from the general business stack. Run point for Step. Be the go-to engineer for how Step connects to the central Beast stack. Scope new integrations, keep the production ones healthy, and take first swing when something between Step and Beast breaks. Document like an engineer. Maintain runbooks, architecture diagrams, and knowledge base articles, and keep the application inventory accurate enough to be a real system of record. Site support and operations Own the San Mateo queue. Triage, resolve, and escalate against SLAs in Serval, our Slack-native ITSM platform. The queue is yours, including the numbers behind it.
