Job description
This is a remote position.
Tech Stack: Node.js/Go, React, AWS/GCP, Stripe Connect/Airwallex, PostgreSQL, Event-Driven Architecture.
The Mission
Wedded Wonderland is the world’s leading luxury wedding and life-milestone platform. We are currently moving from a "Media & Content" model to a "Transaction & Infrastructure" model. We are building the Wonderland Life OS—the financial engine for the $1.5T global luxury milestone economy.
As our Senior Fintech Engineer, you will be the lead architect of Wonderland Pay. This is not a "maintenance" role; you are building the first-ever global payment gateway specifically designed for high-ticket ($100k+), multi-vendor, cross-border luxury celebrations.
The Core Challenge
Luxury celebrations involve high-stakes financial friction: international venue deposits, complex escrow requirements for 18-month planning cycles, and multi-currency vendor payouts. You will build the technical rails that solve these "trust gaps," ensuring that a million-dollar event is as easy to pay for as a cup of coffee.
Key Responsibilities
- Architect & Build: Own the end-to-end development of the Wonderland Payment Gateway. Integrate tier-1 APIs (Stripe Connect, Airwallex) to manage complex global fund flows.
- Escrow & Ledger Logic: Build a robust, milestone-based escrow system to manage long planning cycles, ensuring secure fund holding and automated vendor disbursements.
- B2B SaaS Infrastructure: Engineer the financial backend for our Vendor Pro-Suite, enabling thousands of luxury businesses to manage cross-border invoicing and instant FX settlements.
- Security & Compliance: Implement and maintain bank-grade security protocols (PCI-DSS, SOC2) and automated KYC/AML workflows that feel "invisible" to the luxury end-user.
- Scale & Reliability: Ensure 99.99% uptime for high-value transactions. Optimize system performance for "flash-sale" events (like Wedded Week).
Technical Requirements
- Proven Fintech Experience: 5+ years of software engineering, with a significant background at a leading fintech (e.g., Stripe, Adyen, Airwallex, Checkout.com, or similar).
- The "Stack": Advanced proficiency in Node.js, Go, or Python and experience building scalable Microservices.
- Payment Protocols: Deep technical knowledge of Ledgering, Card Issuing, 3D Secure 2.0, and Cross-Border Treasury.
- Database Mastery: Strong experience with PostgreSQL or similar, specifically in managing highly consistent financial records.
- Builder Mindset: You enjoy being "first on the ground." You can move from high-level architecture to "hands-on-keyboard" execution in the same afternoon.
Why Join our team?
- The Moat: We already have the audience (2M+ members). You are building for a platform that already has global demand.
- The Vision: You’re disrupting an archaic $300B wedding industry and expanding into a $1.5T lifestyle market.
- Technical Ownership: You won't just be a cog in a machine; you will define the standards for how luxury payments are handled globally.

Prepare your application
Use the description above to assess your fit for Wedded Wonderland. This checklist is guidance from Resumize, rather than additional requirements from the employer. Imported listings can be shortened or change after collection, so confirm the complete description and current availability before sending an application.
Match requirements to evidence
Identify the responsibilities and skills the employer explicitly names. For each important requirement, choose one example from your work, education, training, or projects. Explain what you did, how you did it, and what changed as a result. Include a measurable outcome when you can support it. If you lack a requirement, describe related experience accurately instead of adding an unfamiliar skill to your resume.
Put the most relevant examples near the top of your resume. Keep job titles, dates, qualifications, and contact details consistent across your application materials. Use the employer’s terminology when it describes your experience accurately; a copied list of keywords does not explain your contribution. A short, specific bullet is easier to review than a paragraph that mixes several unrelated duties.
Check the working arrangement
Confirm the location, schedule, employment type, and any eligibility requirements on the employer’s site. A remote label does not establish worldwide eligibility or flexible hours. If compensation, benefits, equipment, travel, or contract duration are missing from this listing, write down your questions for the recruiter. Do not assume details from another opening at the same company apply to this role.
Review before submitting
Follow the employer’s requested file format and application instructions. Open your exported resume and check that its text is selectable, its sections read in order, and its links work. Proofread names, dates, and contact information. Share confidential work samples only when you have permission, and use an anonymized example when necessary.
Submit through a trusted employer or recruiting destination. If the original listing has disappeared, search the employer’s careers page for the title rather than assuming the vacancy remains open. Save the application date, job reference, and the version of your resume you sent. Those details help you prepare for a later conversation and avoid submitting conflicting information through several job boards.
Review your resume for writing and readability feedback, or browse other openings if this opportunity is unavailable.
