Position Summary

The Staff Software Engineer in FinTech combines deep technical ownership with systems thinking to build Pax8's next-generation Revenue Lifecycle Management platform. This platform provides the financial infrastructure behind our global marketplace, supporting how technology is bought, sold, billed, settled, and managed.

As Pax8 evolves toward a managed intelligence marketplace, this role also helps build the commerce foundations for the AI economy. You will develop capabilities that support subscription and usage-based consumption models, including token consumption and emerging AI-driven transactions, with the accuracy, reliability, auditability, and scale required of financial infrastructure.

Our FinTech group spans Product Information Management (PIM); Configure, Pricing, Quote (CPQ); Order to Cash (O2C); Fulfillment, Entitlement, and Metering (FEM); Foreign Exchange (FX). We are looking for engineers with meaningful experience across two or three of these areas, with relevant backgrounds that may include payments, subscriptions, revenue recognition, and financial reconciliation.

This role combines that domain experience with a Frontier engineering profile: an AI-native, hands‑on builder who uses spec-driven development and agents to increase engineering productivity while retaining accountability for architecture, code quality, validation, and production outcomes.

The Staff Software Engineer is individually accountable for building, hardening, and operating a system that other teams and business functions depend on. They hold the problem space long enough to develop deep expertise and innovate within it. They earn the right to set its direction by shipping and running the system.

This role is measured on five dimensions: Craftsmanship, Impact, Mentorship, Safety, and State of the Art . At staff level, judgment, systems thinking, and safety must support consequential decisions in systems with broad financial and organizational reach.

• Own, build, and operate a technically complex FinTech system that requires its own technical strategy. Drive precise specifications, architecture, implementation, and production operation.
• Apply domain expertise across relevant revenue lifecycle areas, understanding how product information, pricing, orders, subscriptions, fulfillment, usage, and financial transactions affect one another.
• Build commerce capabilities for subscription and usage-based models, including metering, token consumption, billing, and settlement, in partnership with Product.
• Make consequential calls about what to build, scale, or retire on ambiguous problems. Drive them to clarity through iteration and collaboration, and own the outcome.
• Exercise systems thinking beyond your ownership boundary. Optimize the revenue lifecycle end to end, adjust plans when a local improvement creates downstream problems, and pursue the right fix through influence, contribution, or escalation.
• Own your domain: identify high-
