Founding Sales

Mastra

2d • Remote

About The Position

Mastra is hiring its second dedicated sales hire, a founding account executive who will manage a growing pipeline and help improve the sales motion. The role is full-cycle and focused on mid-market companies, particularly Series A–C organizations with regulatory or infrastructure constraints. Many leads are existing users of Mastra’s open-source framework, and sales cycles are typically measured in mid-single-digit weeks. The role starts with a warm pipeline and involves working with engineering leaders to understand their needs, earn their trust, and close deals.

The seller will represent Mastra’s commercial offerings: its enterprise platform for developing, running, debugging, observing, and scaling production agents (hosted or self-hosted); Agent Builder, a no-code way to build and edit agents that can engage non-technical buyers; and Concierge, an embedded-engineering offering that works alongside customer teams with direct access and SLAs. The work calls for expert discovery, solution scoping, and deal closing.

Mastra’s products and platform are evolving rapidly, and some enterprise features remain relatively new or in early access. The successful candidate will be energized by frequent launches and ambiguity, understand Mastra’s open-source developer framework well enough to discuss customer use cases and challenges, and adapt and improve the existing sales process. The role may involve selling $5,000–$10,000 deals to enthusiastic startups with limited budgets, particularly in the first few months. The posting describes the work as closer to 60 hours per week than 40.

The first 45 days include training and listening to active deals in the first week; ramping to 10–15 first meetings per week in weeks two and three; progressing initial deals toward procurement in weeks four and five; and working toward closing in weeks six and seven. An additional $2,000 is offered for each enterprise license deal closed before the stated early-tenure milestone. The company is a small, fully remote team working across North American and European time zones.

Requirements

• Be able to understand how Mastra’s open-source developer framework works and discuss customer use cases and challenges credibly.
• Be comfortable with ambiguity and constant change.
• Be willing to sell $5,000–$10,000 deals to startups with limited budgets, at least during the first few months.
• Be prepared for a workload described as closer to 60 hours per week than 40.
• Be product- and customer-focused, driven, and willing to adapt and improve an existing process.

Nice To Haves

• Sales experience in developer tools, open-source software, infrastructure, or AI.

• Sell Mastra’s enterprise platform, Agent Builder, and Concierge offerings.
• Adapt, challenge, and improve the existing sales process.
