Full Stack Engineer

We are hiring a Full Stack Software Engineer to help us build secure, easy-to-use fintech infrastructure. This is a full-time engineering hire - a high-ownership early role with broad scope across product, platform, and partner integrations. You’ll help with the current dev team to build features end-to-end and own the technical success of our partner implementations alongside our Customer Success team. We’re looking for someone with strong fundamentals and a few years of production experience who’s ready to grow fast in an early-stage environment - and who actively uses AI to move faster across both engineering and operations. This is a US based remote position reporting directly to the CTO. — About US: We are a US-based fintech embedding trust directly into the payment flow. Our patent-pending technology lets platforms, banks, and marketplaces offer conditional holds inside payments - funds release automatically when rules are met, with payouts to 200+ countries. We sell to platforms and intermediaries operating in high-value, high-risk transactions - marketplaces, brokers, logistics and trade platforms, and banks - so they can offer their SMB customers safer, compliant-by-design global payments. We’re a small, execution-focused team across Engineering, Operations, and GTM. If you want to ship meaningful work in a regulated space where the details matter, this is a good place to do it. — Responsibilities Core Engineering ? Build and maintain full-stack functionality in our web application (TypeScript, React/NextJS, NestJS, AWS) ? Implement backend services and APIs that support secure global payment workflows ? Collaborate with product, design, and QA to deliver a high-quality user experience ? Provide support to answer technical questions from the team ? Apply best practices for secure, testable, scalable code ? Contribute to improvements in system architecture, reliability, and developer workflows Implementation & Partner Support ? Support the technical success of partner implementations: scoping integrations, guiding API usage, and resolving blockers through launch ? Work directly with partner technical teams during integration to troubleshoot and unblock deployment ? Partner with Customer Success to investigate and resolve production issues (infrequent, but responsiveness matters) ? Improve internal tooling and visibility - logs, dashboards, admin tools, event history - to make troubleshooting faster ? Maintain implementation documentation, runbooks, and integration support materials AI Leverage Across Engineering & Operations ? Use AI-assisted development tools actively in day-to-day coding to ship higher-quality work, faster ? Identify opportunities to embed AI into internal processes and operations - support workflows, partner onboarding, documentation, internal tooling - and build the integrations to make it real ? Help raise the bar across the team for what good AI-assisted workflows look like Platform Delivery & Reliability ? Share ownership of platform delivery, including participation in an on-call rotation (issues are infrequent) —

? 1-2 years of professional full-stack software engineering experience (internships and meaningful co-ops count) ? CS degree or equivalent technical foundation - we care more about fundamentals than credentials ? Solid TypeScript and modern web development experience ? Production experience with React or a comparable frontend framework (NextJS) ? Experience building backend services and REST APIs in Node.js (NestJS, Express, or similar) ? Strong debugging instincts - comfortable tracing issues across frontend, backend, and infrastructure ? Clear written and verbal communication - essential for remote work and partner-facing conversations ? Self-starter with high ownership and proactive judgment ? Comfortable in a fast-moving, changing product environment ? Hands-on, active user of AI development tools - you reach for AI as a default, not an afterthought, and have opinions on where it helps vs. where it doesn’t — Preferred Experience: ? Experience supporting B2B API integrations or implementation-heavy products ? Fintech experience, especially payments or compliance-related systems ? Familiarity with international payments concepts (wires, ACH, SWIFT, FX) ? Experience with AWS and cloud deployment workflows ? Interest in security and compliance (SOC 2-aligned engineering practices) ? Experience building internal admin or support tools ? Experience integrating LLMs/AI into product features or internal workflows

? Get in on the ground floor of a growing fintech startup ? Collaborative, execution-focused environment with minimal bureaucracy ?
