Fullstack Software Engineer - AI Native

Are you excited about building products at the intersection of fintech and AI? We’re looking for an AI-native Fullstack Engineer to join Breeze, a Sequoia-backed startup building the universal payment layer to unify all currencies — fiat and crypto — so businesses and consumers can transact seamlessly.

In this role, you’ll work across the stack to design, build, and ship AI-powered, product-facing experiences end to end. You’ll partner closely with Product, Design, and Operations to turn complex financial workflows into intuitive, intelligent systems. This is a hands-on, product-centric role where engineering decisions — including how we apply AI — directly shape what our customers use every day.

This position is hybrid in NYC, with regular in-office collaboration. This hire will be one of our first NYC-based engineers.

• Build and scale user-facing fintech products that leverage AI as a core capability, not an afterthought.

• Own features end-to-end — from technical design and implementation to iteration based on user and model feedback.

• Develop in a fullstack environment using React.js and TypeScript on the frontend, and Node.js and TypeScript on the backend.

• Design and integrate AI-driven workflows (e.g., intelligent automation, decision support, agentic flows, or LLM-powered features).

• Partner closely with Product and Design to shape product requirements, UX decisions, and AI-driven interactions.

• Stay up to date with emerging AI technologies, tools, and best practices, and apply them pragmatically to real product problems.

• Design systems that are secure, scalable, and performant in a payments and financial context.

• Collaborate with Risk, Compliance, and Operations teams to ensure AI-powered workflows meet regulatory and operational needs.

• Communicate clearly with stakeholders and contribute to product planning and prioritization.

• Thrive in a fast-paced startup environment where speed, ownership, and quality all matter.

• 2+ years of professional software engineering experience, ideally in fintech, startups, or other product-driven environments.

• Strong experience building product-driven, user-facing applications.

• Solid fullstack experience with React.js, Node.js, and TypeScript (or similar modern frameworks).

• Demonstrated experience building with AI-native tools or models (e.g., LLM APIs, embeddings, agents, prompt-driven workflows, model orchestration).

• Curiosity and fluency with modern AI trends, tools, and platforms — you actively experiment and stay current.

• Product mindset — you care deeply about usability, customer experience, and business impact.

• Strong problem-solving skills and the ability to own features from concept to launch.

• Excellent communication skills and comfort working cross-functionally with non-engineering partners.

• Familiarity with building scalable, reliable systems and modern web architectures.

• Bonus: experience applying AI in regulated environments (fintech, payments, risk, compliance) or working with financial APIs.

Fast-paced and dynamic – We’re a growing startup that moves quickly.
AI-forward – We embrace new technologies and expect engineers to push how products are built.
Ownership and communication – We value people who take full ownership and communicate clearly across teams.
Continuous learning – You’ll work alongside experts in fintech and payments while staying at the forefront of applied AI.
