**Embedded Firmware Developer (Medical Device) – On-Site, Delhi** We are developing a medical-grade heating and cooling device and require production-ready embedded firmware. The firmware must: • Drive general heating and cooling cycles, making periodic adjustments to maintain the setpoint (stability-focused, not ultra-tight precision) • Continuously monitor sensors and trigger safety alarms when temperatures exceed safe limits or faults are detected • Handle an on-device user interface for clinicians (set temperature, monitor status, acknowledge alarms) **Platform:** Microcontroller family is flexible (Cortex-M / PIC / equivalent), but the design must align with IEC 60601 expectations for safety and reliability. **Deliverables:** 1. Clean, well-structured, compilable C/C++ firmware (RTOS experience preferred) 2. Build instructions and project setup 3. Configuration tables for temperature ranges and alarm thresholds (modifiable without recompilation) 4. Test routine covering heating, cooling, and alarm scenarios for bench validation 5. Documentation explaining control logic and any external dependencies **Critical Requirement (Read Carefully):** This is **NOT a remote role**. The work involves hardware interaction, tuning, and validation. You must be **based in Delhi and available for on-site work**. **Preferred Experience:** • Medical devices or safety-critical systems • Temperature control systems (PID, thermal modeling, etc.) • Sensor interfacing (RTDs, thermistors, ADCs) • IEC 60601 or similar compliance exposure We are moving quickly toward verification and regulatory submission, so reliability and clarity of implementation matter more than over-optimization.

Use this only if you are genuinely based in Delhi and available onsite. Hi, I can develop the embedded firmware for your medical heating and cooling device and support onsite tuning and bench validation in Delhi. I understand the priority is safety, reliability and clear control logic rather than over complicated optimization. I can build clean C/C++ firmware for Cortex M, PIC or a suitable MCU, with heating and cooling cycle control, sensor monitoring, configurable temperature ranges, alarm thresholds, clinician UI handling and fault detection. I’ll structure the firmware with readable modules for control logic, sensors, alarms, UI, configuration and test routines, so the code is easy to verify and maintain during regulatory preparation. I also understand the importance of IEC 60601 aligned thinking, safe states, alarm acknowledgement, watchdog handling and documented validation steps. I can work directly with your hardware onsite, tune the control behavior, test heating, cooling and alarm scenarios, and provide build instructions plus clear technical documentation for your team.

Hi, I can help you develop clean, production-ready firmware for your device with a strong focus on safety, clarity, and reliability. I understand your goal — stable heating/cooling control, continuous safety monitoring, and a simple, reliable UI for clinicians, all aligned with medical-grade expectations. Here’s how I’ll help: ➤ Implement heating/cooling control with stable setpoint management (no over-complex tuning) ➤ Continuous sensor monitoring with clear safety checks and alarm handling ➤ User interface logic for setting temperature, viewing status, and acknowledging alarms ➤ Clean, well-structured C/C++ code (RTOS if needed for better task handling) ➤ Configurable parameters (temperature ranges, thresholds) without recompiling ➤ Test routine to simulate heating, cooling, and fault/alarm scenarios ➤ Clear documentation for logic, structure, and future updates I’ll also help you choose a suitable MCU (Cortex-M preferred for reliability and ecosystem) that fits IEC 60601-oriented development and long-term maintainability. I’ve worked on systems where stability and safety mattered more than speed, so the focus will be on predictable behavior, readable code, and easy validation. Ready to start and align on milestones so we can move smoothly toward testing and compliance. Warm regards, Aditi

Hello, This isn’t just firmware it’s safety-critical control logic, so the approach must prioritise reliability, traceability, and clean architecture from day one. Recommended Platform I suggest an ARM Cortex-M MCU (STM32 series) with optional RTOS (FreeRTOS): • Stable ecosystem, strong tooling, and medical-grade reliability • Easy peripheral handling (ADC, PWM, watchdogs, safety interrupts) • Scalable for future certification needs Architecture Approach • Modular design: Control Loop, Sensor Layer, Safety Manager, UI Handler • Non-blocking state machine for heating/cooling cycles (smooth setpoint control, no oscillation) • Periodic PID-lite or hysteresis-based control (configurable based on your tolerance needs) • Continuous fault monitoring (sensor failure, over/under temp, system anomalies) Key Features Delivered • Clean C/C++ code with clear comments and separation of concerns • Config tables (stored in EEPROM/Flash) for temperature ranges, thresholds, alarms—no recompilation needed • UI integration (setpoint input, live status, alarm acknowledgment) • Watchdog + fail-safe states for critical faults Deliverables • Full compilable firmware + build instructions • Configurable parameter system • Test routines for verification • Documentation (control logic, safety handling, dependencies) Best regards, Arun
