Senior Full-Stack Engineer

We are hiring a Senior Full-Stack Engineer to lead integrations across our payments ecosystem, including BVNK and Bridge, and to help build the next generation of AI-powered tooling inside our CRM and merchant platform. This role is not for a task executor, we already have offshore resources for that. We need a self-directed builder with strong product intuition, someone who enjoys shaping architecture, exploring new capabilities, and staying on the forefront of AI, agentic automation, and modern payment flows. You should be equally comfortable integrating SDKs, architecting backend flows, enhancing React/Next.js frontends, and designing intelligent internal tools that leverage LLMs and automation. This is an opportunity to help define the future of AI-driven payments and Web3-adjacent infrastructure. You will onboard into an existing stack (Next.js frontend, Smart Contract 2.0 via Bridge, Node backend, Infura + Vercel).

You stay on the forefront of AI, agentic automation, and modern payments. You evaluate integration paths and propose improvements proactively. You bring architecture and product ideas, not just code. You thrive in environments where requirements evolve. You think in systems, offer opinions, and challenge assumptions constructively. We want someone who will take an active role in shaping the future of our payments stack, CRM, and AI capabilities.
