Senior Software Developer, API Platform and Ecosystem

What You’ll Do:

• 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).

About You:

• 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.

• Strong experience working with relational databases (e.g., MySQL, PostgreSQL) including schema design, query optimization, and data modeling.

• Solid foundation in distributed systems fundamentals: reliability, scalability, consistency, and failure modes.

• Experience shipping production-grade APIs and thinking deeply about developer experience and platform usability.

• Strong testing mindset (unit, integration, end to end and contract testing) and hands-on CI/CD experience.

• Comfortable collaborating cross-functionally with Product, Design, and customer-facing teams, while keeping work centered on scalable product solutions (not one-off implementations).

Nice to Have:

• 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 building self-serve admin/debug tooling for external developers/customers.

• 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).
