Recognized as a CNBC/Statista 2026 World's Top Fintech company, Paystand delivers over a decade of on-chain payments experience to middle and large enterprises.
Paystand's network services more than one million payors that have moved $20+ billion in volume. With its acquisitions of Yaydoo, Teampay and Bitwage, Paystand's full-stack platform includes agentic AI, its USDb stablecoin, and AR/AP solutions on one tightly integrated network. org, advances the mission to democratize finance through Bitcoin and blockchain technology.
Blockchain automates receivables and payables, cuts time-to-cash, and turns every transaction into revenue instead of cost.
Why We Do It
The current system takes a cut from the people who build, create, and grow — and calls it the cost of doing business. We're here to decentralize finance and hand the power back to the businesses driving the real economy — extended further through Paystand.org's work to democratize finance through Bitcoin and blockchain.
How We Do It
We don't wait for permission or for the industry to catch up — we build the future of finance ourselves, on-chain, in the open. We're looking for people who want to build what comes after it. We're seeking a talented Full-Stack Engineer to play a key role in architecting and implementing user-facing components of the Paystand open banking network. As a member of our dynamic team, you'll collaborate closely with product owners, designers, and fellow engineers to craft web applications that redefine user interactions.
As a FullStack Engineer, you are expected to:
Leverage AI-powered coding assistants to accelerate development velocity and maintain high code quality.
Architect systems with AI integration in mind, ensuring our web applications can seamlessly interface with machine learning models and data pipelines.
Proactively identify and automate manual engineering workflows—such as testing, documentation, and infrastructure management—using AI tools.
Design and develop reusable libraries and frameworks that support complex web applications.
Collaborate with product owners, designers, and other engineers to build the best user experience, ensuring high standards of quality and performance.
Ensure best practices in code quality, security, and performance.
Participate in and influence all phases of the development lifecycle, including system analysis, design, coding, testing, debugging, and documentation.
7+ years of professional software engineering experience, with a track record of independently delivering meaningful products or major capabilities from concept through production.
~ Strong full-stack capability and the judgment to work across frontend, backend, data, infrastructure, and integrations as the product requires.
~ Able to move from an ambiguous business problem to a practical solution: clarify the problem, evaluate tradeoffs, establish an architecture, build the product, deploy it, and improve it using production feedback.
~ Comfortable making progress without a fully prescribed specification while knowing when alignment, deeper analysis, or broader architectural review is needed.

Fluency with AI-assisted and agent-led software development using tools such as Claude, Claude Code, OpenAI Codex, or comparable platforms.
Experience using AI throughout the engineering lifecycle—not only for code generation, but also for discovery, architecture, implementation planning, testing, debugging, documentation, code review, and operational analysis.
Strong engineering judgment about where AI increases leverage and where deterministic software, conventional automation, or direct human review is more appropriate.
Strong understanding of modern application architecture, including modular system design, API design, asynchronous and event-driven processing, data consistency, caching, and integration patterns.
Experience making and documenting architectural decisions based on reliability, security, performance, cost, maintainability, and speed of delivery.
Practical experience with relational databases, data modeling, distributed systems, observability, automated testing, and production troubleshooting.
Familiarity with secure engineering practices appropriate for financial or other high-trust systems, including authorization, data protection, auditability, failure recovery, and idempotent processing.
Full-Stack Product Development:
Strong experience with at least one modern frontend ecosystem, such as React, Next.js, Vue, or Angular, including component architecture, state management, accessibility, performance, and responsive design.
Strong experience with at least one production backend ecosystem, such as Node.js/TypeScript, Python, Java, Go, Elixir, or a
