Paystand is the world's leading blockchain-enabled B2B payments network, transforming commercial finance into a software-driven, zero-fee, and open ecosystem. 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. Its non-profit arm, Paystand.org, advances the mission to democratize finance through Bitcoin and blockchain technology.
**What We Do**
We built the financial system we always thought should exist: zero fees, zero friction, just your money, faster. 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 don't buy that. Every fee we eliminate compounds into growth. 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. Small moves now, monumental results later.
**Join Us**
We're not looking for people who want a job in fintech. We're looking for people who want to build what comes after it. Paystand is where you help lead a financial revolution instead of just reading about one. **We stand on change. Come stand with us.**




**- Role at a Glance**:
**AI-First Engineering Expectations**:
Paystand is an AI-first organization. As a FullStack Engineer, you are expected to:
We believe in augmenting human engineering with intelligence. As an AI-first organization, our expectations for this role reflect that commitment:
- Leverage AI-powered coding assistants to accelerate development velocity and maintain high code quality.
- Proactively identify and automate manual engineering workflows—such as testing, documentation, and infrastructure management—using AI tools.
- Drive technical innovation by actively integrating the latest AI development frameworks and practices into our stack.
**Role and Key Responsibilities**:
- Lead the architecture and implementation of user-facing parts of Paystand's systems.
- Provide technical leadership and mentorship to other engineers.
- 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.
- Advocate for and implement continuous improvement in the development processes and practices.
**Requirements & Qualifications**:




- **Builder Experience**- 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.
- **AI-Native Development**:
- 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.
- Ability to provide agents with effective context, decompose work into verifiable tasks, evaluate generated solutions critically, and maintain responsibility for correctness, security, and maintainability.
- Practical understanding of building AI-enabled product capabilities using model APIs, structured outputs, tool calling, retrieval, evaluations, guardrails, and human-in-the-loop workflows.
- Strong engineering judgment about where AI increases leverage and where deterministic software, conventional automation, or direct human review is more appropriate.
- **Architecture and Engineering**:
- Demonstrated ability to design systems that can evolve and scale w
