Customer Success Engineer (Founding)

Opsin secures how enterprises adopt GenAI — Microsoft Copilot, Google Gemini, and custom agents — by finding and fixing the data access and oversharing risk underneath them. Our buyers are security teams and our deployments are technical.

This is our first customer success hire, and it is a hybrid of implementation engineer and account manager. You will become the front face of Opsin across your accounts, own the full customer journey from onboarding through expansion, and help build the CS function from scratch. This is a senior, founding role working directly with the founders.

Must-haves

• 3–5+ years in a customer-facing post-sales role — Customer Success Engineer, Technical Account Manager, or Solutions/Implementation Engineer
• Cybersecurity experience. You understand how security teams buy, deploy, and measure, and you can hold your own with a CISO or a security engineer
• Startup experience. You have operated at a startup, with minimal process and structure
• Hands-on with automation and workflow tooling — Power Automate, Torq, Tines, and building skills in Claude or ChatGPT
• Track record of owning enterprise accounts end to end — onboarding through renewal and expansion, not support tickets
• Commercial instinct — can get into the technical weeds and then step back to see where an account should grow

Preferred

• Data security, identity, or cloud security background — DSPM, DLP, IAM/IGA, permissions, SSPM, and adjacent
• Experience with Microsoft 365 / Entra ID, Copilot, or GenAI and agent platforms
• Based in the US, ideally in Central time

• Ownership — treats every account outcome as yours to drive, end to end
• Hands-on — comfortable in the technical weeds with security, IAM, and IT teams
• Builder — energized by creating the playbooks and process that do not exist yet
• Bias for action — thrives in a fast-paced startup with minimal structure
• Passionate about AI and cybersecurity
