Job Description

Senior Backend Engineer – Payments Platform

NIR-YU

• Production Node.js backend services and REST APIs — versioned, contract-stable, and hardened • ACH payment workflows end-to-end — debits, credits, retries, failure handling, virtual account ledgering, and reconciliation • Event-driven services using AWS SQS and webhooks for reliable asynchronous processing • PostgreSQL schemas that support complex financial workflows with integrity under failure • CI/CD contributions and test coverage that gives the team genuine confidence to ship • Internal React dashboards and operational tooling when needed • Design documentation, deployment runbooks, and scalability notes that you write because you are proud of the work — not because someone asked • You will occasionally work directly with customers to support integrations, troubleshoot live workflows, and demonstrate platform capabilities — you are comfortable representing the product outside the codebase

Job Requirements

  • 6–7 years engineering experience with a strong backend focus
  • Production Node.js and REST API design
  • Solid PostgreSQL — schema design, query optimization, data integrity
  • AWS — Lambda, RDS, SQS, API Gateway, Secrets Manager
  • OpenAPI / Swagger documentation experience
  • Event-driven systems experience — queues, webhooks, retry and failure logic
  • CI/CD pipeline experience and automated deployment workflows
  • Cross-functional communicator — comfortable working directly with Product, QA, DevOps, and business stakeholders
  • Agile practitioner — sprint planning, backlog grooming, and code reviews are second nature
  • End-to-end owner — you do not hand off, you follow through to production

Benefits

  • Professional development
  • Flexible work arrangements
