Quadratic is an AI-powered, spreadsheet-native analytics platform that connects to CSVs, Excel, PDFs, live databases, and popular services (Postgres, MySQL, Snowflake, BigQuery, QuickBooks, Google Analytics, Mixpanel, Plaid, etc. ) to unify data into live, auditable spreadsheets. Its AI writes formulas, Python, SQL, and charts from plain-English prompts, supports AI agents via the Model Context Protocol (MCP), and exposes an API to read/write cells and orchestrate analysis. Quadratic targets teams and enterprises with features for repeatable, shareable analysis, scheduled tasks, PDF/data extraction, security certifications (SOC 2, HIPAA), and integrations for finance and business intelligence workflows.

📋 Description

• Design and implement network and security infrastructure across multi-site environments: campus, branch, datacenter, and cloud-connected architectures. • Manage firewall platforms at scale: Palo Alto with Panorama, Fortinet with FortiManager, Cisco ASA/FTD, Juniper SRX, and Sophos XG/XGS. • Configure and maintain enterprise switching and routing (BGP, OSPF, HSRP/VRRP, VLANs, spanning tree, QoS) across Cisco Catalyst/Nexus, Juniper EX, Aruba, and Meraki platforms. • Implement and manage SD-WAN solutions, including failover design, policy routing, and carrier diversity. • Apply network segmentation, micro-segmentation, and zero-trust access controls in support of CMMC L2, NIST 800-171, and SOC 2 compliance requirements. • Conduct firewall policy audits, rule cleanup, and hardening reviews; produce documentation that satisfies compliance evidence requirements. • Support VPN and remote access infrastructure (IPsec, SSL/TLS, GlobalProtect, FortiClient) across client environments. • Respond to network security incidents, assist with forensic review, and implement corrective controls. • Integrate network security tooling: IDS/IPS, NAC (Cisco ISE, Aruba ClearPass), SIEM log forwarding, and event correlation. • Translate compliance requirements into network policy: map NIST 800-171 and CMMC L2 controls to firewall rules, segmentation boundaries, and access enforcement. • Produce network diagrams, runbooks, and change documentation that meet audit standards and enable other engineers to maintain what you build. • Travel to client sites up to 25% for major project-based deployments.

🎯 Requirements

• 6+ years network and security engineering in multi-site production environments • US-based work location and US-person status • Hands-on firewall depth on at least two major platforms, including policy management at scale • Routing and switching fluency at operational depth • VPN and remote access design and administration • Compliance audit support, including audit-ready network diagrams and access-control evidence • Ability to read and apply architecture standards set by others without constant design input

🏖️ Benefits

• Travel up to 25% for major client project deployments
