At Fanvue, we don't see financial integrations as just plumbing - we see it as core to the product experience and a growth engine for creators. Every checkout flow, every payout experience, every fraud or financial tool we build is central to delivering trust, speed, and scale for our global community. This role has a fundamental impact on how the business will scale, managing millions of transactions in and out.

As we continue to scale aggressively, we're looking for a world-class Senior Software Engineer - FinTech Integrations to own and drive our checkout and payouts product stream, handling well over $100m+ per year. This is a hands on role for someone who thrives on building complex systems, pushing technical boundaries, and shaping the financial backbone of a high growth platform.

• Scale Integrations with Third Parties: Lead the adoption and optimisation of financial APIs, alternative payment methods (APMs), and payout providers, ensuring resilience, auditability, and user trust.

• Developer Experience Leadership: Constantly improve the developer experience of the codebase, ensuring that financial systems are maintainable, testable, and scalable.

• Cross Functional Collaboration: Partner with product, design, compliance, legal, and operations to align financial systems with business priorities and regulatory requirements.

• Quality & Velocity: Deliver high quality, tested, and reliable systems at the speed of Fanvue's growth.

Must-haves:

• Technical Excellence: Expert knowledge in TypeScript, React, Node.js, and strong SQL or Postgres skills.

• Payments Domain Expertise: You've built or scaled high volume payment and payout systems (hundreds of thousands to millions of transactions, ideally across multiple geographies).

• System Thinker: You're comfortable designing and operating in highly complex, interdependent systems with financial, compliance, and user experience constraints.

• Hands On Engineer: A senior IC who thrives on writing code, solving technical challenges, and pushing systems forward, delivering low latency, fault tolerant checkout flows with resilient retry, fallback, and routing logic.

• Collaborator & Communicator: Skilled at managing stakeholders (internal and external), explaining trade offs clearly, and working cross functionally with transparency.

• High Quality at High Speed: You move fast without compromising on quality, rigor, or security.

• Passion and High Agency: A passion for payment systems and their application to live high velocity systems with high agency to take projects end to end.

Nice to have:

• Marketplace/Platform Context (ideal): Prior experience in a marketplace, creator economy platform, or fintech environment where payments and payouts are core to growth and trust.
