Technical Marketing Manager

Obsidian Security is a global leader in cyber security protecting the SaaS and non-human identity layer modern enterprises run on — from Salesforce and Snowflake to the AI agents now deployed inside them. The Obsidian Security platform gives unified visibility into every human and machine identity, app, and integration across their SaaS estate, detects identity-based and supply chain attacks in real time, and enforces least-privilege access before it's exploited. Trusted by major Fortune 500 companies T-Mobile, Workday, Snowflake, and S&P Global, Obsidian ranked No. 95 on the 2025 Deloitte Technology Fast 500™, growing nearly 1000% from 2021–2024 — helping CISOs turn an unmonitored attack surface into one they can govern with confidence. Obsidian has also been recognized by Forbes as America's Best Startup Employers in 2026.

In August 2026, Obsidian raised $85 million in Series D financing led by Crescent Cove Advisors, with participation from existing investors including Greylock Partners, Menlo Ventures, Norwest Venture Partners, IVP, Wing Ventures, and GV — pushing Obsidian's valuation to $1.1 billion, crossing into unicorn status. Obsidian is using the funding to deepen its R&D in agentic AI security and extend its platform as the standard for governing what AI agents can access and do inside third-party applications.

With global momentum, a growing partner ecosystem including SentinelOne, Databricks, and Google Cloud, and fresh capital from its Series D behind it, Obsidian is scaling rapidly toward long-term growth and IPO readiness.

We are hiring a Sr Technical Marketing Manager - Alliances & Competitive Strategy to own two of the highest-leverage narratives at Obsidian: why we are better together with our strategic partners, and why our architecture solves problems no one else can.

This role sits at the intersection of alliances marketing and technical product marketing, and it owns competitive intelligence for the company. You will define how Obsidian shows up alongside our strategic technology alliances, building the joint value propositions, launch narratives, and enablement that turn partnerships into pipeline and supporting the GTM models that bring those alliances to market. At the same time, you will go deep with Product and Engineering to understand how the platform works, from our knowledge graph to our data depth and detection architecture, and elevate that "how" into a durable "why": why Obsidian is uniquely positioned to secure third-party applications and AI agents where alternative architectures structurally fall short.

You will be the positioning authority the field, our partners, and our executives turn to for evidence-based answers on how we win, both in architecture and in direct competition.

This is a senior individual contributor role for someone who can think strategically, move quickly, and help shape how we scale both partner marketing and competitive positioning at Obsidian.
