** About This Role
** The Quantum Leap Systems Integration Engineer is responsible for defining and driving end‐to‐end integration across Carrier data center solutions, including chillers, liquid cooling (CDUs), BMS, and DCIM platforms, to deliver a turnkey customer experience. This role focuses on reducing startup and commissioning effort through system interoperability, auto‐discovery, and standardized processes across multiple products. The engineer will operate in a highly ambiguous environment, working across engineering, field, and product teams to design scalable integration approaches rather than executing predefined requirements.

Success in this role requires strong industry knowledge, systems thinking, and the ability to lead without a playbook.

* Demonstrated ability to diagnose integration failures, communication issues, protocol mismatches, and telemetry quality problems
* Ability to work cross functionally with platform engineers, controls engineers, and field engineering teams
* Familiarity with Linux environments, networking fundamentals, and secure system configuration
* Strong documentation and communication skills for mapping requirements, interfaces, and test procedures
* Experience integrating: DCIM tools (Nlyte, Eco Struxure IT, Trellis), BMS/BAS systems (WebCTRL, Metasys, Desigo, Honeywell), HVAC systems (chillers, CDUs, CRAHs, pumps, towers)
* Hands-on experience with:
Time-series databases, Edge computing frameworks (K3s, Azure IoT Edge, AWS Green grass)
* Experience working in air-gapped or on‐prem-only deployments
* Knowledge of cybersecurity principles for operational systems
* Experience with version control, CI/CD pipelines,…
