Open Call for Founders / Founding Teams - Product Management and Engineering

Open Call for Founders / Founding Teams (Product Management / Engineering roles)

At Mercury, we're looking to accelerate several of our AI products that our customers love like Command, CLI, and MCP. We're building for ambitious people of all kinds, and are a company made of founders and small technical teams trying to change the world. As part of that, we're taking open applications for founders or small technical teams (Eng+) that want to work together on building the AI products of the future.

This isn't a fixed role. We expect the nature of work is changing, and small teams of people paired with AI product surface and autonomy to build can create 10x outcomes. Apply as a small team or as an individual.

What you'll do

• Find the problem: Work close enough to customers that you spot what matters before anyone assigns it to you — then decide it's worth building.
• Build and automate: Automate the workflow end to end using Command, CLI, MCP, and the rest of our AI stack.
• Ship fast: Quick understanding, tight iteration, deploy rapidly to customers.
• Measure impact: Measure the impact honestly, kill what didn't move, and double down on what did.
• Run autonomously: Pick the target, ship the thing, and own the outcome.

What you should bring

• Experience shipping something real: a product, a tool, a company, or an open-source project people actually use.
• Cross-functional capability: PMs who can prototype, engineers with product taste.
• Strong opinions about AI products and the judgment to recognize fast when one of them is wrong.
• Hands-on experience building AI products with AI, with knowledge about RAG, evals, and agent harnesses as a plus.
• A bias for moving fast, measuring, and treating failed experiments as the price of finding what works.
• Focus on craft where impactful and a willingness to avoid over-polishing.
• Clear communication and ownership of outcomes, targeting real business impact and customer value.
