Job description

About the role

MedSolutions Technology and Innovation Inc. is seeking a Firmware & Biosensing Algorithm Integration Engineer with a strong research orientation to join our team in Bacoor City, Cavite. MedSolutions integrates licensed biosensing algorithm libraries — heart rate/pulse rate, respiration rate, SpO₂, and activity — into wearable devices, and we need an engineer who can own the integration, build, tuning, and validation of these algorithm suites across our VSynC wearables and our smart-watch and band partners' devices.

This role sits at the intersection of firmware engineering and applied algorithm integration. You will be the in-house technical steward of our biosensing algorithm libraries: standing up the algorithms on target hardware and host test platforms, keeping underlying algorithm libraries, tuning and post-processing their outputs, and validating vital-signs accuracy against clinical reference devices. You will work directly with our partners' teams and act as a technical bridge between MedSolutions, and partner engineering groups. This is a full-time position for someone who is curious by nature, enjoys collaborating across companies, and wants to see their work translate into better patient outcomes.

What you'll be doing

• Serve as the technical owner and first point of support for our licensed biosensing algorithm libraries within MedSolutions, coordinating between our team, and partner engineering teams

• Integrate biosensing algorithm libraries into the firmware of Bluetooth-enabled smart bands, smart watches,

• Build and maintain the algorithm libraries across targets — cross-compile for BLE SoCs and for host/PC and Linux test platforms (static and shared libraries)

• Translate and adapt biosignal and vital-signs algorithms into efficient, real-time firmware that runs within the memory, timing, and power constraints of a wearable

• Tune algorithm parameters and design post-processing on top of the library outputs

• Run sensor front-end quality checks against the sensor integration guidelines — sampling rate, SNR, optical crosstalk / black-patch light-leakage, channel saturation, PPG/ACC clock synchronization, and green/red/IR channel mapping — and feed findings back to the hardware team

• Support smart watch and band customers as they integrate the algorithms into device firmware, from initial evaluation through validation on target hardware

• Collaborate with cross-functional and cross-company teams — hardware, software, algorithm, clinical, and quality engineers — to ensure clean integration and reliable performance

• Develop and maintain firmware and algorithm test plans, execute tests, and troubleshoot issues

• Research current firmware, wearable sensing, and biosignal-algorithm technologies and bring relevant findings back to the team

• Participate in code reviews, design discussions, and process improvement initiatives

What we're looking for

• Bachelor's degree in Biomedical Engineering, Electrical/Electronic Engineering, Computer Engineering, or a related field

• 5+ years of experience in firmware development, including at least one project integrating a third-party or licensed signal-processing/algorithm library (C static/shared library) into embedded firmware under memory and timing constraints

• Genuine inclination toward research, a curious mind, and enthusiasm for working alongside partner companies and their engineering teams

• Strong interest in PPG/biosignal processing and the integration of vital-signs algorithms into embedded devices

• Experience with wearable biosensing algorithm stacks and their integration into firmware

• Experience in using software analytical tools

• Proficiency in embedded C/C++ programming and microcontroller architectures

• Software development experience on BLE SoC

• Understanding of the Bluetooth protocol (BLE/GATT), including communication principles and application of Bluetooth technology

• Strong understanding of real-time operating systems, communication protocols, and firmware design patterns; familiarity with FreeRTOS and Zephyr, and proficiency with SPI, I2C, and UART

• Python (or similar) for test, validation, and tuning tool

• Familiarity with the software development lifecycle, testing, and debugging techniques, and ability to independently complete code writing and debugging

• Experience with AI agentic programming, or willingness to adopt agentic programming

• Ability to read electrical schematic diagrams and familiarity with both analog and digital circuits

• Experience with medical device software development and compliance with relevant standards (e.g., IEC 62304); awareness of quality/regulatory workflows is a plus

• Strong problem-solving, analytical, and communication skills, a strong sense of responsibility and teamwork, and an innovation-driven mindset

Nice to have

• Familiarity with Bluetooth audio and HID profiles (HFP/HSP/A2DP/AVRCP/HID) for consumer-crossover devices

• Experience bringing up or porting compiled algorithm libraries across Windows, Linux, and macOS toolchains

• Exposure to clinical validation study design and reference instrumentation (capnography, reference pulse oximeters)
