Founding Product Engineer
About this role
Mondrio is hiring a Founding Product Engineer to own end-to-end product modules and shape our AI-driven pricing and monetization platform; you’ll work closely with customers, product, and leadership to define architecture, ship production-quality systems, and make every feature drivable by LLM agents. This is a hands-on role on a small team where technical leadership, customer-facing scope, and precision around financial logic matter.
What youll do
- Build and 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, TUIs, web, and vendor integrations.
- Ensure features are drivable by LLM agents via our MCP/FastMCP server 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 (Pydantic models for SKU, Proposition, Persona, Pricing, etc.).
- 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 set engineering culture and best practices.
- Treat money-handling code as load-bearing and prioritize root-cause analysis for production issues.
- Adopt and improve an AI-native SDLC where agents assist with code and automated review gates.
What Mondrio is looking for
- 8+ years of engineering experience with strong full-stack skills and proven ownership of product areas at startup/ staff scope.
- Deep backend expertise; experience with FastAPI, Python, and MongoDB or a comparable stack.
- Credible frontend skills with React and TypeScript and the ability to ship a clean UI independently.
- History of taking ambiguous customer problems to shipped features without a PM.
- Interest or experience in B2B monetization: pricing models, packaging, quoting, billing, or CPQ.
- Familiarity with AI-assisted development tools and experience integrating agent tooling or MCP-like servers is a plus.
- High standards for correctness, especially for financial logic; US work authorization required (no visa sponsorship).
Company at a glance
At Mondrio, we’re on a mission to build the future of pricing: agentic pricing management. We believe that monetization should be data-driven rather than a one-time exercise. It should evolve as products, markets, or sales motions change. Our AI-native platform equips companies to bring that pricing intelligence into strategy and deal decisions.
