At Vanta, our mission is to help businesses earn and prove trust. We believe that security should be monitored and verified continuously, and we empower companies to practice better security and prove it with ease. Vanta has a kind and talented team, and while some have prior security experience, many have been successful at Vanta without it. Vanta's Corporate Engineering team is the infrastructure layer that keeps 1,500+ people connected, secure, and moving fast. AI is now central to how that happens, and this role leads the team that owns the backbone underneath it. Corporate Engineering owns the shared AI platform for Vanta's internal systems: identity and access for AI tools, cost visibility and controls, sanctioned tooling and guardrails, and the enablement that helps people use those tools well. We do not own product AI, which stays with Engineering, and we do not replace the AI work happening inside individual departments. We build the engineering layer that makes all of it safer, cheaper, and better supported. The company has moved fast. AI assistant use is widespread across every function, MCP infrastructure is live and self-serve company-wide, internal apps ship on a hosted platform, and AI spend has grown to the point where attribution and guardrails genuinely matter. What does not exist yet is a single owner for that platform layer. That is this role. As Sr. Manager, AI Engineering, you will lead a small, senior team, write the charter for what Corporate Engineering owns versus enables, and build the platform that lets the rest of Vanta adopt AI quickly without accumulating cost, risk, or duplication. What you’ll do as a Senior Manager, AI Corporate Engineering at Vanta: Lead, coach, and grow a senior team spanning platform engineering and technical program management. Set clear direction, hold a high bar, and give the team explicit permission to push back with data. Own the AI access layer end to end: identity and authentication for AI tools, connector

Vanta has a kind and talented team, and while some have prior security experience, many have been successful at Vanta without it. We believe that security should be monitored and verified continuously, including the security of your supply chain. The Vendor Risk Management (VRM) product was designed to provide software buyers with tools to evaluate the security of their vendors by inventorying vendors, prioritizing risks, automating security reviews and remediating findings. VRM or Third party Risk Management (TPRM) presents a massive opportunity for Vanta - representing a market of $5-$10B in ARR and a CAGR of 10.8% driven by secular tailwinds in the industry that requires more focussed and deeper scrutiny of the company’s supply chain. As a Senior Software Engineer with full stack focus, you’ll be responsible for driving complex projects across our technical stack and mentor our talented engineering team. Your past experience will be leveraged to accelerate the evolution of our Vendor Risk Management product and help software buyers continuously and comprehensively monitor risks across their vendor supply chain. Our business has found incredible product-market fit and has monetized effectively since the day we signed our first customer. We’re growing at a blistering pace, which presents career-defining opportunities for engineers to accelerate their growth and to contribute to a rapidly-scaling company.

Vanta has a kind and talented team, and while some have prior security experience, many have been successful at Vanta without it. Customers increasingly use AI agents like Claude Code, Codex, Cursor, and internal Slack agents to run their business processes, and security and compliance work is no exception. For those agents to do that work, they need access to Vanta’s trust graph and intelligence layer. Vanta is building for that world: security and compliance products that customers can use through Vanta, through third-party agent platforms, and inside their own internal tools. As Senior Product Manager, Agent Ecosystem, you will own Vanta’s external agent surfaces: MCP, CLI, and plugins in marketplaces like Claude Code, Codex, and ChatGPT. Your job is to make Vanta the trusted compliance layer that agents rely on. You will define the strategy, ship the products, and own the outcomes. What you’ll do as a Senior Product Manager, Agent Ecosystem at Vanta: Own the strategy and roadmap for Vanta’s agent ecosystem products. Define how agents discover, access, and safely use Vanta capabilities, partnering with the platform teams that own APIs and authentication. Hold outcome parity as a product principle: work a customer can complete in Vanta should be possible through MCP, CLI, and plugin surfaces too. Lead marketplace and plugin launches, aligning product, engineering, legal, security, and go-to-market around each one. Partner with engineering and design to ship secure, reliable developer products. Build the developer-facing marketing motion: external agent documentation and customer stories that show what MCP and CLI users have unlocked. Partner with the product partnerships and alliances team on co-marketing with agent platforms like Anthropic and OpenAI,

You're the one who figures out what the plays should be—then makes sure they hit.

You'll own demand generation end-to-end: from the annual campaign strategy for your segment to the post-event debrief to the budget that makes it all move.

About the Role Supabase's Partnerships function is scaling fast - spanning Technology Partners, Solution Partners, Startups, and Cloud Partnerships.
