Open Call For Founders / Founding Teams - Product Management And Engineering

Mercury · San Francisco, CA, New York, NY, Portland, OR, or Remote within Canada or United States

Mercury is a fintech company focused on building financial tools and AI-driven products for businesses. This open call is specifically designed for founders or small technical teams interested in joining the company to accelerate the development of AI-integrated products such as Command, CLI, and MCP. The role is highly autonomous, functioning less like a traditional position and more like an entrepreneurial unit within the company. Day-to-day responsibilities involve identifying customer problems, building and automating end-to-end workflows, shipping features rapidly, and iterating based on honest impact measurement. Candidates should have a proven track record of shipping real-world products, tools, or open-source projects. The ideal applicant is a "full-stack" thinker—engineers with strong product intuition or product managers capable of prototyping. Experience with AI development, including RAG, evaluation frameworks, and agent harnesses, is considered an asset. This opportunity is well-suited for individuals who thrive in high-autonomy environments, possess strong opinions on AI product design, and are comfortable with the rapid experimentation required to scale impactful financial technology solutions.

Open call for Founders / Founding Teams (Product Management / Engineering roles) In 1973 at Xerox PARC, Bob Metcalfe sketched a way for many computers to share a single wire — borrowing the throughput math from his study of Hawaii's ALOHAnet — and he and David Boggs built it and measured it until it held. Behind Ethernet was a two-person team that turned a contested idea into the measured standard now carrying almost all the world's wired traffic. 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 Here are some things you’ll do on the job: 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. You should: 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 Learn more about what we're building: Mercury Command — Complete financial work end-to-end with AI. Tell Mercury what to do in natural language; it stages the action and executes with your approval. Mercury MCP & CLI — Give your AI agents direct access to verified financial data, or work with your Mercury account straight from the terminal. The bank of the future knows your business — Immad on what we're building toward and why now is the moment. What happens next? Submit your application and our recruiting team will follow up. We're genuinely open to connecting with founders and teams at any stage — whether you're a strong fit for something we're actively building toward right now, or this is the start of a longer relationship we pick back up when the opportunity is right. If you're building, we want to know you.
