About the role
- Design, build, and operate MaintainX’s public-facing REST APIs, with a focus on consistency, scalability, and great developer experience. Want to see what it currently looks like? Head over here!
- Implement platform standards and patterns: authentication/authorization, rate limiting, versioning, filtering, pagination, idempotency, error semantics, and backwards compatibility
- Design and implement robust batch and bulk API operations that enable high-volume data synchronization and large-scale migration workflows for enterprise customers
- Decouple the REST API layer from monolithic dependencies while implementing strong contract testing to ensure GraphQL changes do not impact REST API stability, improving overall reliability and iteration speed
- Build scaffolding, templates, and shared libraries that make connector/integration development faster and more consistent
- Improve CI/CD pipelines, release automation, and quality gates for integrations and ecosystem services
- Produce strong developer documentation and reference implementations (For eg. SDKs)
- Contribute to the infrastructure and workflows that allows integrations to be published, versioned, and supported in our internal or external integrations marketplace (Eg. Workato, Tray)
- Enable automation-driven onboarding flows (e.g., connection creation, credential management, environment configuration)
- Build standardized integration foundations and reusable building blocks for enterprise systems (e.g., SAP recipes and BTP building blocks; productized Oracle EBS/NetSuite and Microsoft D365 integrations)
- Ensure integrations meet enterprise expectations around security, auditability, performance, and operability
- Own production services and platform components end-to-end: monitoring, on-call, incident response, root-cause analysis, and iterative hardening
- Drive performance tuning and reliability improvements based on data (SLIs/SLOs, logs, traces, and metrics)
Benefits

- Competitive salary and equity opportunities
- Comprehensive healthcare coverage- Comfortable collaborating cross-functionally with Product, Design, and customer-facing teams, while keeping work centered on scalable product solutions (not one-off implementations)

- Solid foundation in distributed systems fundamentals: reliability, scalability, consistency, and failure modes
- 4+ years of professional software engineering experience building backend systems, APIs, or platform products (seniority flexible based on impact and scope)
- Strong experience with service-oriented backend development and one of the following languages (TypeScript, Go, C#) and willingness to learn other languages based on context
- Experience shipping production-grade APIs and thinking deeply about developer experience and platform usability
- Strong experience working with relational databases (e.g., MySQL, PostgreSQL) including schema design, query optimization, and data modeling
- Experience with integration ecosystems: API platforms, SDKs, iPaaS/connectors, marketplaces, webhooks/events, ETL/sync patterns
- Familiarity with enterprise identity/security patterns (OAuth2/OIDC, API keys, token rotation, least privilege)
- Experience with ERP ecosystems (SAP S/4HANA or ECC 6, SAP BTP, Oracle EBS/NetSuite, Microsoft Dynamics)
- Experience with Workato, Tray, or Zapier from a product/platform engineering perspective (e.g., building connectors, not just recipes, workflows, or zaps—though familiarity with those is valuable too)
- Experience building self-serve admin/debug tooling for external developers/customers
