We are looking for a Senior Desktop Systems Engineer to join client project — Othello, a SalesTech startup building a real-time AI platform that empowers sales professionals to succeed in every conversation. The platform integrates with calendar, email, and CRM, delivering smart pre-meeting insights, live in-call guidance, and post-call performance analysis (buyer sentiment, action items, recommendations).
You will join an early-stage, well-funded team (pre-seed at $20M valuation, backed by Long Journey Ventures and founders of DoorDash, Axonius, Exodigo, and Chime) at a critical moment — just before the seed round — with enterprise pilots already running with companies of $10B+ market cap, including U.S. Steel.
