Senior Full Stack Engineer - Fintech

Job Description

Job Description

Career Renew is recruiting for one of its clients a Senior Full Stack Engineer - Fintech - this is a fully remote role for New York based candidates. Salary range: 175-225K USD gross yearly plus benefits.

Our mission is to transform how money moves. We believe stablecoins will underpin a new financial fabric, one that is faster, more global, and more efficient than today's siloed systems. That is why we are building AUSD and the stack, a full service platform that makes issuing, managing, and integrating stablecoins seamless, whether you're a developer, fintech, or institution. With AUSD, stablecoins become programmable, composable, and ubiquitous by default.

We believe digital dollars should be a public good: trusted, accessible, and built for real-world utility. Our mission is to drive adoption through customizable, user-friendly on-ramps that make stable, dollar-based value available on-chain.

We're backed by world-class investors including Paradigm and Dragonfly, and we're growing a team to reimagine how value moves online.

We're intentional about who we bring on. If you're passionate about stablecoins and want to help create more open, intuitive ways for people to engage with money, let's talk.

ABOUT THE TEAM

We bring the discipline of high-performance finance teams and the creativity of a fast-moving crypto-native startup. We're a small, mission-driven group of builders who move fast, sweat the details, and hold a high bar for excellence, in product, code, and culture.

You'll be joining a tight-knit team that values clear thinking, extreme ownership, and high-velocity decision making. We operate in short feedback loops, support one another without ego, and are deeply motivated by the opportunity to build foundational infrastructure for the future of money.

JOB SUMMARY

We're seeking a Senior Fullstack Engineer to take end-to-end ownership of features and products across the stack, from interfaces to reliable backend infrastructure. You'll work closely with product, design, operations, finance, and our external partners and customers to gather requirements, prototype quickly, and ship with confidence. You have strong product taste, a bias toward MVP thinking, and you're as comfortable reasoning about user experience as you are about backend systems, API designs or database schemas. Our stack includes TypeScript, React, REST APIs, Docker, Kubernetes, Prometheus, and Grafana. This is a role where you’ll own it end to end, from the first prototype through launch, iteration, and beyond.

We value real-time collaboration and prefer candidates located close to Eastern Time, while welcoming exceptional engineers across Pacific Time through GMT. Regardless of where you are located, your working hours will need to have a majority overlap with ET business hours.

BASIC QUALIFICATIONS

• 5+ years of fullstack development experience, with 3+ years in TypeScript/Node.js and a modern frontend framework (React preferred)

• Fluency with relational databases and SQL

• Proven ability to ship production systems, frontend and backend, with high uptime and minimal maintenance burden

• Strong product instincts and an eye for good design; you can work from a Figma file but you'll also push back when something doesn't feel right

• Comfortable working directly with external partners and customers on requirements gathering, integration, and iterative feature development

• MVP mindset: you know how to scope a milestone, ship it, learn from it, and iterate fast

• Strong commitment to clean code principles and automated testing

• Deep understanding of API design, versioning, documentation, and modern authentication patterns

• Excellent communication skills and experience collaborating across product, design, and operations in remote, asynchronous environments

PREFERRED QUALIFICATIONS

• Experience in fast-paced, high-growth startup environments where you've worn many hats

• Track record of prototyping and launching customer-facing products, not just internal tools

• Familiarity with performance profiling, latency reduction, and service-level adherence

• Background in designing and operating event-driven architectures

• Expertise in Docker, Kubernetes, Prometheus, and Grafana

• Passion for building tools, internal or external, that meaningfully improve how people work with money

• Hands-on experience building in crypto, including working with onchain libraries and services, and integrating with blockchain infrastructure

• Experience integrating or interacting with blockchain node software (e.g., Geth, Solana validators)
