About the role

What You'll Do

  • Own the platform integrations layer end-to-end — building reliable connectivity, data ingestion/exports, and orchestration for complex, multi-step, long-running processes (including retries and state management)
  • Build and maintain both inbound and outbound integrations with third-party platforms (e.g., Salesforce and other external/open APIs)
  • Design and implement in-house services capable of processing large volumes of data under tight time constraints, optimizing for throughput and latency
  • Design and maintain RESTful and webhook-based APIs, applying strong patterns for rate limiting, pagination, error handling, versioning, and backward compatibility
  • Collaborate with product and platform teams to define integration requirements and execution guarantees (SLAs/SLOs)
  • Build observability (logging, tracing, metrics) into integration systems, and use it to monitor, troubleshoot, and continuously improve production reliability
  • Lead medium/large feature development independently within agile processes, mentoring engineers and conducting code reviews along the way
  • Stay current with emerging technologies and evaluate new tools for potential adoption

What You Bring

  • 5+ years of software engineering experience with a focus on backend systems
  • Strong experience with Node.js (NestJS), JavaScript, and TypeScript; Java (Spring Boot) is a plus
  • Proven experience integrating with external/third-party APIs, building both inbound and outbound integrations (any platform — pattern/concept experience is transferable)
  • Demonstrated experience building high-volume data services — e.g., optimizing data processing/ingestion time under real-world constraints
  • Strong problem-solving and analytical skills, with the ability to debug complex technical issues and implement robust solutions
  • Solid understanding of authentication and authorization protocols, including OAuth 2.0, OIDC, SAML, and JWT
  • Proficiency with MongoDB and comfort working across relational and NoSQL data stores; familiarity with React a plus
  • Strong communicator, comfortable leading cross-functional collaboration with both technical and non-technical stakeholders
