Founding Engineer - Financial Platform Infrastructure

Core Job Description

This is a rare **0→1 opportunity** to build a high-scale financial platform from the ground up within a profitable, established ecosystem. While most fintechs spend years struggling to find customers, this team already has massive distribution at the point of company formation. We are looking for a hands-on Founding Engineer to bridge the gap between company incorporation and global financial operations by building a neobank-style platform that handles everything from KYC and multi-currency accounts to complex money movement and card issuing. You will own the architecture and technical direction of a product that helps international founders launch and scale their businesses globally.

Key Responsibilities

• Architect and build core financial infrastructure including KYC/KYB workflows, ledger systems, and transaction state machines.
• Design and implement integrations with regulated banking partners, card issuers, and payment rails (ACH, Wires, FX).
• Develop provider-agnostic systems that allow the platform to integrate multiple financial partners without vendor lock-in.
• Build robust, secure APIs and data models capable of handling complex reconciliation and event processing.
• Manage the full lifecycle of feature development, from initial database schema design to production deployment and internal compliance tooling.
• Work directly with the founders to translate product goals into scalable technical solutions and engineering standards.

Requirements

• 3–8+ years of professional software engineering experience with strong backend or full-stack fundamentals.
• Proven track record of building production-grade APIs and distributed systems.
• Mastery of database design, data modeling, and asynchronous workflows (queues, events, retries, and idempotency).
• A high degree of engineering judgment; you understand when to build for scale and when to optimize for speed.
• Exceptional ownership mentality—you are comfortable taking a problem and a goal and figuring out the path to completion independently.
• Highly hands-on approach with a desire to write production code daily in a fast-moving, early-stage environment.

Nice-to-Haves

• Direct experience in fintech, neobanking, or payments (specifically ledgers, reconciliation, or money movement).
• Background at high-growth financial technology companies such as Stripe, Adyen, Airwallex, Brex, or similar infrastructure providers.
• Familiarity with the regulatory nuances of KYC/KYB and international banking infrastructure.
• Experience building multi-currency or FX-heavy platforms.
