## Job description

#### **Company overview**

Infinite is a stablecoin payment processor. We offer businesses turnkey APIs and SDKs to instantly move money anywhere in the world at a fraction of the cost of traditional solutions. The founding team previously built and scaled products at financial services category leaders [Coinbase](https://coinbase.com/) and [Sardine](https://sardine.ai/).

#### **The opportunity**

As our **Founding Engineer**, you will define, build, and maintain the technical foundation of our platform. You will join us in-person in a fast-paced, high-ownership environment where you will take ownership of everything, from architecture and implementation to production reliability for mission-critical services. You will partner directly with founders and early customers to translate real-world requirements into robust, high-quality products.

#### **Key responsibilities**

1.  **Full Stack & End-to-End** – Design, implement, and operate complete services and user-facing features, from requirements gathering through production support
2.  **System Design & Architecture** – Develop highly available, event-driven systems for ledgering, compliance, and risk that scale with transaction volume while maintaining zero downtime
3.  **Implementation Engineering** – Embed with customers, collect feedback, and iterate rapidly to ensure our roadmap aligns with user needs
4.  **Technical Decision-Making** – Balance speed and long-term scalability, selecting appropriate technologies (Next.js/TypeScript, C#, Go, Python, modern cloud infrastructure) for each problem domain

#### **Required skills & experiences**

-   5–10+ years of professional software engineering, including the delivery of 0-to-1 products and scaling them in production
-   Proficiency in at least two of: Next.js/TypeScript, C#, Go, Python
-   Hands-on expertise with asynchronous and event-driven architectures
-   Full-stack ownership spanning modern front-end frameworks, back-end services, and cloud infrastructure
-   Excellent written and verbal communication; ability to influence internal and external cross-functional stakeholders

#### **Preferred qualifications**

-   Proven expertise with AI-assisted development tools—especially Cursor or windsurf, to accelerate code generation, refactoring, and automated test creation
-   Practical experience deploying lightweight machine-learning models for real-time anomaly detection, automated compliance reporting, or incident triage in production systems
-   Experience designing and contributing to fintech, payments, or ledgering systems (e.g., double-entry ledgers, payments, clearing, or settlement)
-   Experience integrating banking, payments, or compliance providers, or a demonstrated ability to onboard unfamiliar financial APIs quickly
-   Prior leadership or mentorship in a high-growth engineering team

#### **Ideal candidate**

The ideal candidate is a passionate and driven engineer with a hacker's mindset. You are comfortable both leading a team and being hands-on with code. You thrive in fast-paced environments and are eager to tackle complex challenges that drive our company's success.
