Job description

About the Role

We are building our Singapore corporate technology function from the ground up. Our enterprise stack centers on Lark and Weaver OA, with an ambitious automation roadmap ahead. We are looking for a hands‑on Enterprise Systems & IT Manager to own this stack end to end — applications, integrations, identity, endpoints, network, and automation.

This is a builder role: you will architect, deploy, integrate, and run these systems yourself, bringing in vendors only where it makes sense. It is not a vendor‑management or pure helpdesk role.

What You'll Own

• Enterprise Applications & Integration
• Administer Lark as our core workspace: tenant administration, org structure, approval flows, and the Lark Open Platform (bots, apps, APIs)
• Own the Weaver OA platform: workflow and approval design, form building, and integration with surrounding systems
• Support and integrate Kingdee ERP: master-data sync, finance and HR workflow touchpoints
• Build and maintain API integrations across Lark, Kingdee, Weaver, and other company-selected internal enterprise system

Automation & AI

• Own and execute the internal automation roadmap
• Design and ship joiner‑mover‑leaver (JML) automation across identity, devices, and applications
• Automate workflows using the Lark and Weaver workflow engines, n8n / Power Automate, and scripting (Python or PowerShell)
• Evaluate and roll out AI productivity tooling with sensible governance

Identity & Endpoint

• SSO and access management across Lark, Kingdee, Weaver, and other core systems
• Full laptop lifecycle: procurement, provisioning, MDM, patching, secure offboarding
• IT asset inventory and management

Security & Operations

• Office network (firewall, Wi‑Fi, VPN) and endpoint security baseline
• Access control, audit logging, and support for ISO 27001 / SOC 2‑aligned practices
• Run day‑to‑day IT support for Singapore staff, hands‑on now, building the function as we scale

What We're Looking For

• 5+ years in enterprise IT, including at least one 0→1 build (or full rebuild) of a company's enterprise systems
• Hands‑on Lark administration in production, including the Lark Open Platform (bots, approval flows, APIs) — not just end‑user familiarity
• Real implementation or integration experience with Kingdee, Weaver, or comparable Chinese enterprise ERP / OA platforms
• A proven automation track record — be ready to walk us through three workflows you've automated, with the flows or scripts to show
• Practical API integration skills: comfortable reading API docs, testing in Postman, and writing glue code between systems

Bonus Points

• Microsoft 365 / Intune or Google Workspace administration experience
• ISO 27001 or SOC 2 implementation or audit‑support experience
• Internal AI tools or agents shipped to real users (beyond experimentation)
