ToolSense - The AI- and IoT-driven FM Operations Platform. Cut Costs. Reduce Downtime.

What we do at ToolSense

ToolSense is building the leading AI- and IoT-driven FM Operations Platform for Facility Management. Our mission: become the global leader in FM Operations, a massive industry that is critical to how our world works and where many processes are still handled with Excel, pen & paper, and WhatsApp.

This leads to downtime, chaos, and high costs.

We're changing that.

ToolSense digitizes the entire FM Operations: from machines and robots to vehicles, buildings, and work orders. We connect assets via QR codes and IoT, automate workflows with AI, and create real-time transparency across the entire fleet. The result: up to 80% less downtime, 20% lower machine costs, and a far easier day-to-day for the people working on the ground.

With over 200 customers in 30+ countries, including ISS, Dussmann, VINCI, and WISAG, multiple innovation awards, and growth funding from GRO Capital, a leading European B2B SaaS investor, we're ready to scale across Europe and beyond.

Our Goal

We want to become the leading FM Operations Platform and drive the digitization of this industry. To get there, we need a strong product team that turns customer problems into clear business priorities and makes ToolSense better every day.

Your Role

As an IoT Support & Integration Engineer, you’ll ensure our IoT integrations run reliably from edge devices on machines through to data in the backend.

You’ll troubleshoot complex integration issues across hardware, communication layers, and data pipelines, test new IoT devices, and handle escalated IoT support cases.

You’ll also support internal teams such as Sales, Customer Success, Product, and Engineering with technical IoT expertise, and own our IoT support documentation by keeping articles accurate, useful, and up to date.

This role is perfect for someone who enjoys hands-on technical problem-solving, works independently, and can make complex IoT topics clear and actionable.

• Test new IoT devices

3rd Level Technical Support

• Handle escalated IoT support cases that go beyond first and second line support
• Provide technical guidance and answers to internal colleagues — including Sales and Customer Success — when IoT-related questions arise

Documentation Ownership

• Act as owner of the IoT support documentation
• Continuously maintain existing support articles and create new ones to reflect changes in product, integrations, and known issues.

• SQL & REST APIs — solid basic understanding of querying databases and interacting with REST APIs
