Job description

MaintainX is the world’s leading AI-powered maintenance and asset management platform, serving 13,000+ customers including Duracell, Shell, Cintas, and Brenntag. We raised $150M in Series D funding led by Bessemer Venture Partners and Bain Capital Ventures, bringing our total funding to $254M. We were named to the Forbes 2025 Cloud 100, the definitive ranking of the top 100 private cloud companies in the world. We’re growing fast and hiring the talent to match.

MaintainX is the world leading mobile-first workflow management platform for industrial and frontline workers. We are a modern IoT enabled cloud based tool for maintenance, safety, and operations on equipment and facilities. MaintainX powers operational excellence for 12,000+ businesses including Duracell, Univar Solutions Inc., Titan America, McDonalds, Brenntag, Cintas, Michaels, and Shell. We recently completed a $150 million Series D round, bringing our total funding to $254 million and valuing the company at $2.5 billion.

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).

What’s in it for you:

• Competitive salary and meaningful equity opportunities.

• Healthcare, dental, and vision coverage.

• 401(k) / RRSP enrollment program.

• Take what you need PTO.

• A Work Culture where:
