### **About the Role**
An early\-stage AI\-native B2B SaaS company building an AI\-driven pricing and monetization platform is looking for a **Founding Product Engineer** to join as one of the first engineers on the team. This is a hands\-on, high\-ownership role where you will define architecture, own entire product modules end\-to\-end, and work directly with customers and leadership to shape how the product evolves.
The platform helps B2B companies continuously optimize their pricing lifecycle — covering packaging design, scenario simulation, quote recommendations, deal coaching, discount governance, and more. You will be instrumental in moving core financial logic server\-side, extending a typed pricing ontology, and ensuring every feature can be driven by LLM agents.
This role is **on\-site in San Francisco, CA**. **US work authorization is required; visa sponsorship is not available.**
### **What You'll Do**
* Own whole product modules end\-to\-end: scope with customers, design versioned APIs, build the UI, ship, and iterate. * Design and evolve architecture for agentic AI systems across Slack bots, terminal UIs, web interfaces, and vendor integrations. * Ensure product features are drivable by LLM agents via MCP/FastMCP server endpoints and conversational interfaces. * Move pricing and business logic off the client into backend services to preserve financial fidelity. * Extend and maintain a typed pricing ontology using Pydantic models (e.g., SKU, Proposition, Persona, Pricing — with Customer, Contract, and Quote on the roadmap). * Lead technical discussions and architectural reviews to keep systems robust, extensible, and secure. * Establish testing, observability, deployment, and performance monitoring practices for AI\-driven features. * Mentor peers, influence product strategy, and help set engineering culture and best practices. * Treat money\-handling code as load\-bearing; prioritize root\-cause analysis for production issues. * Adopt and continuously improve an AI\-native SDLC where agents assist with code generation and automated review gates.
### **What We're Looking For**
**Must\-haves:**
* 8\+ years of software engineering experience, with demonstrated ownership of full product areas at startup or staff\-level scope. * Deep backend expertise with production experience in **FastAPI, Python, and MongoDB** (or a comparable modern stack). * Proven track record of shipping end\-to\-end modules: customer scoping versioned API design React UI production delivery. * Credible frontend range with **React and TypeScript**; able to ship a clean, polished UI independently. * Experience designing server\-side business logic, versioned APIs, and ensuring testing, observability, and deployment for AI\-driven features. * Experience building or integrating AI\-assisted features and agent\-driven workflows (e.g., LLM\-driven interfaces, MCP\-like endpoints). * Familiarity with **B2B SaaS monetization concepts**: pricing models, packaging, and quoting. * High standards for correctness, especially around financial logic. * Authorized to work in the United States without visa sponsorship.
**Nice\-to\-haves:**
* Experience building MCP servers or tooling for LLM agents. * Background in billing, CPQ, metering, or pricing systems. * Experience with data\-dense frontend components and/or conversational interfaces. * Familiarity with data residency, SOC 2, or GDPR\-compliant development practices. * Prior experience as a technical founder, co\-founder, or early employee who shipped a 0\-to\-1 B2B product to paying customers.
### **Compensation \& Benefits**
* **Salary:** $200,000 – $250,000 USD per year * Early\-stage equity commensurate with a founding\-team role * Opportunity to shape product, engineering culture, and company direction from day one
### **Location**
This is an **on\-site role based in San Francisco, CA**. Candidates must be willing and able to work in person. US work authorization is required; the company does not offer visa sponsorship.
