Hire IoT Developers — Connected Device Experts

An IoT developer builds the software systems that connect physical devices to the internet and to each other. This spans firmware communication, cloud ingestion pipelines, message brokers, device management platforms, and the dashboards that make sensor data actionable. Kultrix IoT developers work across the full stack — from device-level protocol handling to the web application that operators use to monitor their fleet.

Most engagements begin within 48 hours of contract signing. For specialised requirements such as industrial protocol expertise or specific hardware platforms, a one-week lead time is typical. We match you with a developer whose background aligns with your specific device type and cloud platform.

Our primary platforms are AWS IoT Core and Azure IoT Hub. We have experience with Google Cloud IoT (now replaced by Pub/Sub), as well as self-hosted options like EMQX and HiveMQ. The right platform depends on your existing cloud investment and fleet scale, which we assess during the initial scoping call.

Yes. We have implemented protocol bridges for Modbus RTU/TCP, OPC-UA, BACnet, and PROFINET, enabling legacy industrial equipment to feed data into modern cloud architectures. We use purpose-built gateway hardware or software bridges depending on the installation constraints.

Security is built in from the start. We provision each device with a unique X.509 certificate, enforce mutual TLS on all cloud connections, rotate credentials via a secure OTA mechanism, and apply least-privilege IAM policies to limit what each device can access in the cloud. We also conduct threat modelling for the device communication model before implementation begins.

Yes. Our IoT developers typically build the full stack — from the MQTT ingestion pipeline through to the React dashboard that operations teams use. For complex dashboard requirements with advanced charting, we bring in a specialist frontend developer. Either way, you get a complete, production-ready product rather than just a backend service.

Edge computing means processing data on or near the device rather than sending everything to the cloud. You need it when latency requirements are under 10ms, when network connectivity is unreliable, when raw data volumes would make cloud costs prohibitive, or when local actions need to happen without a round trip to the cloud. Kultrix IoT developers assess your use case and recommend the right split between edge and cloud processing.

We architect for fleet scale from the start — using connection pooling, device shadow patterns for state management, fan-out message architectures, and time-series databases like InfluxDB or Amazon Timestream to handle high-frequency telemetry without performance degradation. We have worked with fleets ranging from dozens to hundreds of thousands of connected devices.

Yes. A focused proof-of-concept engagement — typically two to four weeks — is a great way to validate device-to-cloud connectivity, protocol choices, and dashboard design before committing to full development. We scope the PoC clearly so you know exactly what will be demonstrated and what the path to production looks like.

All Kultrix IoT developers are mid-to-senior level with a minimum of four years of connected systems experience. Every developer is assessed on cloud platform knowledge, protocol handling, and data pipeline design before joining our bench. We do not place juniors on client engagements.

We offer monthly retainer and time-and-materials models. Retainer engagements include a fixed allocation of developer hours with a guaranteed response SLA. T&M engagements are billed weekly against tracked hours. Both models include transparent timesheets and a dedicated account manager.

Kultrix is a product-focused agency, not a talent marketplace. Every developer is a Kultrix employee or long-term contractor with vetted skills. We manage quality, handle replacements if a fit is not working, and provide a dedicated account manager. You get the speed and flexibility of a freelancer with the accountability and continuity of an agency.
