Full Stack Software Engineer
Full Stack Software Engineer (US Remote)
US Citizen or Green Card holder ONLY.
Salary: 80k
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)

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
