Job Description:

Our mission is to grow financial inclusivity and efficiency. Concretely, we issue stablecoin-powered debit cards, so that card payments work the way they should:

• Merchants receive payment instantly - rather than multiple days later.
• End users can pay with currencies or their choice, held in their own custody.
• This is a big deal in developing markets such as LatAm where users want to shield themselves from local currency inflation, but are restricted by their local banking systems.

Why Join:

• ?Founding Team: Join our early stage, engineer-driven team of former Meta, Binance, Mastercard veterans. You can expect to have broad technical responsibility, and receive unfiltered access to business operations & decisions.
• ?Achievements: In just a year, we’ve synchronized blockchain and card payments on both the technical and regulatory levels, launching our first live debit card with one of the biggest crypto wallets (Argent). We’ve raised $3m with top Fintech & Blockchain VCs, and are on path to operate globally where we are needed most.
• ?Social Impact: Our product fosters financial equality by providing stable, secure access to essential financial services, retaining full control of assets by end users.
• ?Market Disruption: We enable near-instant payments, eliminating delays and costs that affect merchants and consumers alike.

What You’ll Do:

• ?️Build the foundation: Help define and develop the core backend systems that will underpin our product, connecting blockchain and fintech systems in novel ways.
• ?Innovate: We operate a debit card for third-party non-custodial wallets. This has never been done before. You’ll be solving new problems, not rehashing existing solutions in a different form.
• ?Work with customers: Get your hands dirty integrating our system for our first customers, seeing a full sales and deployment cycle.

Reward for Impact:

• Meaningful equity & competitive cash salaries
• Unique work experience you won’t get elsewhere

What We’re Looking For:

• ?Technical expertise: Senior/staff engineering experience with a focus on creating scalable, resilient backend systems.
• ?Proactive mindset: Sometimes we look for a long term solution, and sometimes a quick fix. You should have a “Can do” approach that identifies all options and makes the right call.
• ?Excited by impact: Create a real change in the world that unleashes economic potential.
