About the role

Open call for founders or founding teams (Eng+) to collaborate on building AI products (Command, CLI, MCP) at Mercury. Flexible, non-fixed role focused on autonomous small teams delivering AI-powered financial products.

Responsibilities

  • 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 the workflow end to end using Command, CLI, MCP, and the rest of our AI stack.
  • Ship to customers fast — quick understanding, tight iteration, deploy.
  • Measure the impact honestly, then do the next one. Kill what didn't move; double down on what did.
  • Run as an autonomous team — pick the target, ship the thing, own the outcome.

Qualifications

  • Have shipped something real - a product, a tool, a company, or an open-source project people actually use.
  • Be dangerous across the stack: PMs who can prototype, engineers with product taste.
  • Have strong opinions about AI products and the judgment to recognize fast when one of them is wrong.
  • Hands experience building AI products with AI, and knowledge about RAG, evals, agent harnesses a plus
  • Move fast and measure. Expect most experiments to fail and treat that as the price of finding the ones that don't.
  • Care about craft where it's impactful and resist polishing what isn't.
  • Communicate clearly and own outcomes - we want real business impact, customer time/pain saved, and a path to scaling what works

Skills

Required:Product management with AI product experienceSoftware engineering across stack
Nice to have:Understanding of AI concepts (RAG, evals, agent harnesses)

Benefits

  • Salary and equity ranges highly competitive within the SaaS and fintech industry (to be shared if moving forward)
  • Opportunity to connect with founders and teams at any stage
  • Open to longer-term relationship opportunities as projects evolve
