## About the role

##### About the Role

This is a founding-level, hands-on engineering role at an early-stage B2B SaaS company building an AI-driven pricing and monetization platform. You will own entire product modules end-to-end, work directly with customers and leadership, and help shape both the architecture and engineering culture of a small, fast-moving team. Financial precision and technical leadership are central to this role.

##### What You'll Do

- Scope, design, build, and iterate on whole product modules independently, from customer conversations through to shipped features.

- Design and evolve architecture for agentic AI systems across web, conversational, and vendor integration surfaces.

- Ensure product features are drivable by LLM agents via MCP-style servers and conversational interfaces.

- Move pricing and business logic off the client and into backend services to preserve financial fidelity.

- Extend and maintain a typed pricing ontology using Pydantic models covering entities such as SKU, Proposition, Persona, and Pricing.

- Lead architectural reviews and technical discussions 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 and prioritize thorough root-cause analysis for production issues.

- Adopt and improve an AI-native development workflow where agents assist with code and automated review gates.

##### What We're Looking For

- 8 or more years of software engineering experience with proven ownership of product areas at startup or staff-level scope.

- Strong full-stack skills: deep backend expertise with FastAPI, Python, and MongoDB (or a comparable stack), plus credible React and TypeScript frontend range.

- Track record of taking ambiguous customer problems to shipped features without a dedicated PM.

- Experience building or integrating AI-assisted features and agent-driven workflows, including LLM-driven interfaces or MCP-style endpoints.

- Familiarity with B2B SaaS monetization concepts: pricing models, packaging, quoting, billing, or CPQ.

- High standards for correctness, especially in financial logic and money-handling code.

- Ability to design and ship versioned APIs and typed data models.

- Experience building MCP servers or tooling for LLM agents is a plus.

- Familiarity with billing, metering, or CPQ systems is a plus.

- Experience with data-dense frontend components or conversational interfaces is a plus.

- Prior experience as an early employee or technical founder shipping a 0-to-1 B2B product is a plus.

- Must be authorized to work in the United States; no visa sponsorship is available.

##### Compensation & Benefits

Salary range: **$200,000 to $250,000 USD annually.** Equity is expected given the founding-level scope. Visa sponsorship is not available.

##### Location

On-site in **San Francisco, CA.** Candidates must be based there or willing and able to relocate.
