Job description

  • Design and implement services that support revenue workflows, payment logic, and invoicing pipelines
  • Build robust APIs and full-stack features, leveraging type-safe ORM tooling for schema management and query composition
  • Own integration with internal systems (e.g., Salesforce, NetSuite) and external providers (e.g., banks, payment processors)
  • Implement structured financial logic such as contingent payments, commission calculations, and milestone-based billing
  • Integrate AI/LLM capabilities using Claude (Anthropic) and leverage Cursor as a core development tool to accelerate delivery
  • Build and deploy infrastructure in AWS
  • Translate complex business rules into deterministic backend logic: commissions, milestones, payee splits, and contingent payments.
  • Implement robust data flows between Client Processing, Deal Management, and Authoritative Data domains.
  • Work closely with product managers, architects, and finance stakeholders to deliver end-to-end features

  • Hands-on expertise with AWS services: EC2, Lambda, RDS, S3, IAM
  • Familiarity with event-driven systems (Kafka, SQS, or similar), API integrations, and microservice patterns
  • Strong understanding of data modeling, transaction workflows, and secure service architecture
  • Comfortable working across systems where compliance, auditability, and financial accuracy are critical

  • Familiarity with Salesforce, NetSuite, Concur, or related business platforms
  • Experience with serverless architecture and FaaS patterns
  • Understanding of multi-party payments, invoicing workflows, or tax handling (e.g., 1099s, VAT)
