The Role

We are looking for a Senior Full-Stack Engineer to build secure, reliable tools for our Operations, Risk, and Customer Support teams.

  • Build interfaces that present accurate transaction trails and system data without requiring direct database queries.
  • Design secure APIs and integrations that connect internal tools to core payment, identity, and support systems.
  • Implement role-based access control, approvals, audit logs, and other safeguards for sensitive actions and data.
  • Prototype and deliver useful features quickly while maintaining security, reliability, and code quality.
  • Monitor production behavior, resolve issues, and improve the performance and reliability of internal systems.
  • Work directly with internal teams to understand their processes, define requirements, and improve tools over time.

Required competency and skillset to be a waver:

  • At least five years of professional full-stack software engineering experience.
  • Strong experience with modern frontend development using JavaScript or TypeScript and a framework such as React or Vue.
  • Backend development experience in one or more languages such as Node.js, Go, Java, Python, or PHP
  • Strong backend development experience, including API design, databases, authentication, and service integration.
  • Experience building admin dashboards, internal portals, case-management tools, or CRM integrations.
  • A strong understanding of authorization, role-based access control, auditability, and secure handling of sensitive data.
  • Solid SQL and data modeling skills, with the ability to turn complex data requirements into safe, usable workflows.
  • Strong testing, debugging, observability, and continuous delivery practices.
  • Clear communication and the ability to work effectively with non-engineering teams.
  • A bachelor’s degree in Computer Science, Software Engineering, or a related field, or equivalent practical experience.
