We are looking for Full-Stack Developers to join our Connected Data team in the Engineering Organization. This role has openings at Senior+ level positions.

The Connected Data team’s mission is to connect our customers’ siloed operational data to MaintainX — through integrations, sensor management, and the APIs that make it all possible. We own the systems that ingest, normalize, and surface the data that powers MaintainX’s automations and asset intelligence, including our Connectors (Ignition, Kepware, MQTT/Sparkplug B), our On-Premise Agent, and the Automation and Alerting engine. The team operates as multiple squads and works closely with our largest enterprise customers to bring their equipment data online.

What You’ll Do:

• Build and evolve our integrations platform — Design, develop, and maintain the connectors and data pipelines that bring customer data into MaintainX from industrial systems (Ignition, Kepware, MQTT brokers, OPC UA servers, SCADA, historians).
• Ship IoT and sensor experiences end-to-end — Implement backend ingestion, transformation, and storage for high-volume sensor telemetry, and the frontend surfaces customers rely on to monitor device health, manage fleets, and trust their data.
• Own services that move real data, at scale — Contribute to the reliability, performance, and observability of the team’s core services with a strong operational mindset.
• Collaborate across the product — Partner with Product Managers, Designers, and engineers across MaintainX to turn unstructured, real-world industrial data into intuitive product experiences.
• Write high-quality, maintainable code — Deliver clean, testable C#, TypeScript, and React code across backend services, the on-premise agent, and customer-facing UI.
• Raise the engineering bar — Participate in code reviews, contribute to architectural discussions, and help drive the long-term health of our platform through technical pitches, POCs, and bug bashes.

You’ll work across our stack (C#, TypeScript, React, React Native, Node.js, and GraphQL) — Web, Mobile, and On-Premise applications. Connected Data is one of the most polyglot teams at MaintainX: our connectors and the on-premise agent are written in C#, our web and mobile surfaces are TypeScript, React, and React Native, our service layer uses Node.js, and our APIs expose both REST (our public API) and GraphQL (to the rest of the product). You will work meaningfully in all of them.

• You’ll work with the team to build, maintain and optimize product features that focus on how our users get their operational data into MaintainX and act on it.
• You’ll actively own team features or systems and define their long-term health, while also improving the health of surrounding systems.
• You’ll mentor other engineers and review code.
• You’ll improve engineering standards, tooling and processes & bring best practices in planning, developing, testing and deploying industry compliant code.

About You:

• 5+ years of professional experience in full-stack software development.
• Strong programming skills in C# and TypeScript, with experience building production-grade applications in both — or strong experience in one and a genuine appetite to get to production quality in the other.
• Solid experience with React, Node.js, and consuming or building GraphQL APIs.
• Experience designing, building, or integrating against REST APIs and understanding the tradeoffs (versioning, pagination, rate limiting, idempotency, backwards compatibility).
• Comfortable with relational databases and data modeling for high-throughput, event-driven workloads.
• Proficient at writing understandable, maintainable, and testable code, with an eye towards reliability and observability.
• Strong communicator: explaining complex technical concepts to designers, support, product, and other engineers is no problem for you.
• You thrive in a fast-paced, customer-facing environment where the data you work with comes from real factories, real equipment, and real people on the frontline.

Nice to Have:

• Experience with industrial / OT protocols and platforms: MQTT, Sparkplug B, OPC UA, Modbus, Ignition, Kepware, or similar SCADA / historian / PLC ecosystems.
• Experience building IoT data pipelines — ingestion, time-series storage, anomaly detection, or device fleet management.
• Experience building or maintaining on-premise applications or hybrid cloud/edge deployments.
• Experience with cloud providers (AWS / Azure / GCP) and service deployment — particularly AWS IoT, Timestream, or SiteWise.
• Experience with Docker, Kubernetes, and modern CI/CD pipelines.
• Experience with observability tooling such as Datadog, and with running production services against meaningful SLIs/SLOs.
• Experience with LLM-powered features (extraction, mapping, summarization) in production integrations.

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 high impact Culture:
• You’ll work with Smart, Humble Optimists across the globe.
• Meritocratic environment where ideas and outcomes are publicly celebrated.
