About the Role
Join an early-stage B2B SaaS pricing company as a hands-on product engineer, owning complete product areas from customer discovery through launch and iteration. You will shape the architecture and engineering practices behind AI-driven pricing and monetization tools, where reliable financial logic and useful agent-driven workflows are essential.
What You'll Do
-
Scope product needs with customers, design versioned APIs, build user interfaces, and deliver complete product modules.
-
Design and evolve systems for AI-driven workflows across web applications, conversational interfaces, and third-party integrations.
-
Make product features usable by LLM agents through MCP-compatible services and other agent tooling.
-
Move pricing and business logic into backend services to support accurate, dependable financial calculations.
-
Extend typed data models for pricing concepts and develop maintainable APIs and services.
-
Establish testing, observability, deployment, and performance practices for production systems.
-
Lead technical discussions, mentor teammates, and investigate production issues with a focus on root causes.
What We're Looking For
-
At least 8 years of software engineering experience, including startup experience and staff-level ownership of product areas.
-
Strong backend skills with production experience in Python, FastAPI, and MongoDB or a comparable stack.
-
Practical React and TypeScript experience, including independently shipping polished user interfaces.
-
Experience taking ambiguous customer problems from scoping through delivery, including designing versioned APIs and data models.
-
Background integrating AI features or agent-driven workflows; MCP-like tooling experience is a plus.
-
Familiarity with B2B SaaS monetization, such as pricing, packaging, quoting, billing, or CPQ.
-
High standards for correctness in financial logic and authorization to work in the United States without visa sponsorship.
Compensation & Benefits
Salary range: $200,000 to $250,000 annually. Visa sponsorship is not available.
Location
On-site in San Francisco, California, United States.
