About this role.

AI Summary

MaintainX is hiring a senior backend/platform engineer to build and operate its public REST API platform and integration ecosystem. The role emphasizes scalable API design, enterprise-grade authentication and authorization, bulk data workflows, connector foundations, SDKs, and integration marketplace infrastructure. The engineer will improve CI/CD and quality controls while owning production reliability through monitoring, on-call response, incident analysis, and performance tuning. Candidates need at least four years of backend engineering experience, strong TypeScript, Go, or C# skills, relational database expertise, distributed-systems knowledge, and a strong testing mindset. Experience with iPaaS platforms, OAuth/OIDC, ERP integrations, and developer tooling is advantageous.

Sample interview questions
How would you design a versioning and backward-compatibility strategy for a public REST API?

I would establish explicit versioning conventions, publish a compatibility policy, and favor additive changes such as new optional fields or endpoints. For breaking changes, I would introduce a new version, maintain the prior version through a defined deprecation window, use contract tests to prevent accidental regressions, and communicate migration guidance early.

How would you implement a safe bulk API operation for enterprise data synchronization?

I would use asynchronous jobs with idempotency keys, validation before execution, clear per-record result reporting, and retry-safe processing. The API should provide job status and error details, enforce rate and payload limits, and include audit logs and observability so customers and support teams can diagnose failures.

What is your approach to separating a REST API from a monolithic GraphQL dependency?

I would define stable REST-facing contracts and introduce an anti-corruption layer or dedicated service boundary that maps REST resources to internal capabilities. Contract and integration tests would verify REST behavior independently of GraphQL implementation details, while gradual migration, telemetry, and fallback plans would reduce production risk.

How do you secure an API ecosystem used by third-party integrations?

I would apply OAuth2/OIDC where appropriate, scope tokens according to least privilege, rotate credentials, and protect sensitive endpoints with strong authorization checks. I would also implement rate limiting, audit logging, secure secret storage, input validation, and monitoring for anomalous access patterns.

Describe how you would improve reliability for an integration platform that has recurring incidents.

I would first use logs, traces, metrics, and incident records to identify the highest-impact failure modes and define relevant SLIs and SLOs. I would prioritize fixes such as retries with backoff, idempotent processing, circuit breakers, better alerting, and dependency isolation, then validate improvements through load, failure, and end-to-end tests.

MaintainX is a leading mobile-first work execution platform for industrial and frontline teams. More than 13,000 customers, including Duracell, McDonald’s, Shell, DHL and Volvo, use MaintainX to cut unplanned downtime and run better operations, across 13.9 million managed assets and 79.5 million completed work orders.

In August 2026 MaintainX became part of Autodesk, joining Autodesk Operations Solutions, the organization unifying Autodesk’s operations platform alongside Tandem, FlexSim and Fusion Operations. Autodesk’s strategy is to converge design, make and operate into one continuous lifecycle: design an asset, build it, run it, then feed what you learn running it back into the next design. Autodesk had design and make. Operate is the phase that tells you what actually happened, and it is ours.

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).

Our mission is to keep the physical world running. Factories, fleets, hospitals and campuses stay up because the people who maintain them have tools worth using. That is what we build.

Compensation and benefits. Base pay is one part of the package. Depending on the role, compensation may also include commission, an annual bonus and equity. Benefits differ by country. For roles in the United States, Autodesk’s benefits are described at benefits.autodesk.com. For roles in Canada and other countries, the plan differs on health coverage, retirement and leave, and your recruiter will walk you through it.

Belonging. We take pride in a culture where everyone can thrive. More at autodesk.com/company/global-belonging. More on where this is going: Autodesk CEO Andrew Anagnost on building the future of connected operations, and AOS SVP Stephen Hooper on welcoming MaintainX to Autodesk.
