Caleb Provost

Lead systems engineering, R&D, and engineering management for a connected smart-textile sensing platform (wearable/bedding sensor pads and hub connectivity system) used in care-facility environments.

• Directed the response to a critical in-field firmware regression, coordinating an emergency release rollback and remediation plan that protected deployed units across 4 care facilities from a data-loss failure mode
• Led a build-vs-buy evaluation and cost/effort estimation for the connected Hub's connectivity architecture, informing a roadmap decision to build hardware variants for existing deployments and new products to close capability gaps in the current platform
• Write and debug embedded firmware (ESP32, BLE Mesh, WiFi) for smart-textile sensing systems, including firmware updates and fixes across deployed devices, and contribute to electronics design such as schematic review, component selection, and sensing circuits
• Led cross-functional deployment reviews with several major care-facility customers, using field analytics to shape subsequent deployments and product development
• Support design controls, verification & validation planning, and QMS documentation (Software Requirements Specification, System & Software Architecture Specification, Cybersecurity Risk Assessment) for a Class II, 510(k)-exempt regulated medical device

Designed, built, and tested embedded firmware and electronics for automotive sensing and infotainment systems, working end-to-end from early prototypes through production deployment.

• Wrote and debugged embedded firmware in C/C++, Node.js, and Python for real-time sensor integration, CAN bus communication, and BLE/IoT features on ARM and Tensilica-based microcontrollers, optimizing for memory, CPU, and power efficiency in resource-constrained environments
• Contributed to electronics design (schematic review, component selection, power circuits, and analog signal conditioning) and built and validated physical prototypes from early concept through production
• Developed system-level integration of sensors, firmware, and data outputs enabling real-time vehicle monitoring and media features across 3 production platforms
• Designed and executed verification test frameworks (unit, integration, system-level) validating performance, reliability, and durability under real-world operating conditions, reducing manufacturing failure rate by 98%

Supported product development in a regulated manufacturing environment through hands-on prototyping, test fixture design, and compliance verification. Continued in a part-time consulting capacity after transitioning to a full-time role at Radio Sound, Inc.

• Designed and built 5+ custom test fixtures and control systems for product validation and long-term reliability testing, reducing test setup time by 4 hours a day
• Developed and programmed data acquisition systems to capture and analyze sensor data for performance characterization across hot beverage and chilled beverage product lines
• Built risk assessment processes and supported compliance activities aligned with applicable regulatory requirements, contributing to sign-off on 5 product releases
• Performed root cause analysis on 2 recurring failure modes, delivering a redesign recommendation (material and vendor change) that reduced the coffee product line's failure rate by 48%
