Team

Payward, the parent company behind Kraken, Ninja Trader, x Stocks, Breakout, and a growing portfolio of businesses, is scaling fast through active M&A.

Every acquisition brings its own collaboration stack, its own Google Workspace tenant or Slack instance, its own domains, its own archiving obligations.

Someone has to bring all of that into one secure, compliant, well‑run environment.

That someone is you.

Role Overview

This role owns the productivity and collaboration platforms, Google Workspace, Slack, and Zoom across the Payward family of brands, with a focus on M&A integration.

When we buy a company, you are the person who scopes the migration, moves the users, channels, files, and configurations, untangles the acquired environment, and lands it cleanly inside Payward’s security and identity stack.

You’ll work across Legal, Compliance, IT, Security, Corporate Development, and the acquired companies themselves, often as the most knowledgeable person in the room on how these platforms actually connect.

This is a build‑and‑own role, not a keep‑the‑lights‑on role.

Responsibilities

• M&A Integration (Core Focus)
• Drive collaboration‑platform integration end‑to‑end for each acquisition, scoping, planning, executing, and closing out migrations of users, Slack channels, Google Workspace Drive, mailboxes, and configurations from acquired companies into the Payward environment.
• Assess acquired‑company collaboration stacks during and after diligence: what they run, how it is configured, what the security and compliance gaps are, and what it takes to consolidate.
• Rationalize overlapping tools across brands, decide what migrates, what sunsets, and what stays, and see those calls through.
• Build repeatable playbooks, tooling, and automation so each successive integration is faster and cleaner than the last.
• Coordinate cutover timelines and TSA‑driven dependencies with Corporate Development, Legal, and the acquired teams.
• Collaboration Platforms
• Own Google Workspace, Slack, and Zoom at multi‑entity enterprise scale, architecture, governance, licensing, configuration, and day‑to‑day operations across the brand portfolio.
• Build and maintain integrations between collaboration tools and the broader identity and security stack (Okta, Global Relay, e Discovery tooling, archiving platforms).
• Define and enforce cross‑brand platform governance standards; build automation that makes the secure path the easy path.
• Collaborate with HRIS and IAM teams to manage clean onboarding and offboarding across platforms and entities.
• Email & Domain Security
• Own email security infrastructure across brands, filtering, quarantine, impersonation defenses, and DMARC/SPF/DKIM hygiene, and raise the bar as new entities and threats arrive.
• Manage a large, multi‑registrar, multi‑brand domain portfolio (Cloudflare, Mark Monitor, and others); lead DNS migrations, audits, and consolidation as brands come in.
• Respond to phishing campaigns, insider threat signals, and anomalous domain activity with speed and precision.
• Compliance & Legal Support
• Lead legal hold management, e Discovery queries, and data productions across email, Slack, and Google Drive, across multiple entities.
• Architect and maintain compliant archiving infrastructure (Global Relay, Smarsh, Virtru) as new businesses are onboarded and legacy ones sunset.
• Produce and defend evidence for regulatory and audit obligations (17a‑4, ISO, external auditors), working directly with Legal and Compliance.
• Security & Access Control
• Design and maintain DLP rules, group access controls, and data access policies across collaboration platforms and entities.
• Lead insider threat reduction initiatives, access revocation, high‑risk extension management, public channel governance, during and after integrations, when risk is highest.
• Own platform‑level incident response: investigation, containment, and post‑incident improvement.
• Tooling & Vendor Management
• Evaluate, onboard, consolidate, and sunset Saa S tools across the collaboration and security stack as the portfolio grows.
• Lead vendor relationships, procurement, and renewals; make build‑vs‑buy‑vs‑sunset calls and see them through.
• Build automation that reduces manual toil and improves governance at scale.

Qualifications

• 4‑6 years of hands‑on experience administering Google Workspace and Slack at companies with 1,000+ users, including complex migrations and governance work.
• Demonstrated experience owning or leading a technology migration in an M&A or systems‑consolidation context, ideally more than one.
• Solid email security experience: filtering, quarantine.
