Erdem Simsek

Senior Software Engineer

Firmware for Nordic's next-generation low-power Wi-Fi SoC, focused on secure boot, power management and Zephyr bring-up.

• •Secure boot and root of trust with MCUboot, TF-M and a trusted execution environment
• •Zephyr bring-up for the new SoC, with fixes contributed upstream
• •Low-power Wi-Fi firmware using DTIM, TWT and long sleep schedules
• •Pre-silicon validation on FPGA and Cadence Palladium emulators
• •Started the team's LLM tooling initiative, including custom MCP servers and a skill repository

Senior Embedded Software Engineer

Firmware for a super-sport race-car electro-hydraulic power steering (EHPS) system, plus the test automation around it.

• •Wrote the Cortex-M4 firmware driving a 4 kW, 12 V three-phase BLDC motor that generates the steering pressure
• •Worked on the device's security, including secure boot
• •Built a Behave test rig that emulated the car over CAN using .dbc messages
• •Enabled the teams to run system-level verification against our local rig by injecting their CAN signals into the system
• •Guided younger engineers as a senior member of the team

Lead Software Engineer

Autonomous-robot software across two teams: the functional-safety software team, and the embedded-Linux platform team handling power and communication.

• •Developed firmware to functional-safety standards and wrote the reports for the certification process
• •Led the migration of the safety controller from uC/OS-II to FreeRTOS
• •Automated the safety-standard test suite to run daily on CI
• •Refactored the codebase to improve RAM and flash usage
• •Designed Linux-to-Cortex-M communication using VirtIO and OpenAMP, and worked between teams to resolve inter-team bugs
• •Built command-line and UI debugging tools in Rust

Member of Technical Staff

Worked closely with customers onboarding their code onto our health sensors, providing tailored drivers and hands-on development support.

• •Delivered tailored drivers and example apps for the MAXREFDES104 wrist-worn health platform (PPG, ECG, accelerometer)
• •Built an app streaming sensor data over BLE and USB-CDC with FatFS local storage
• •Designed a queue-based API standardising communication between the application processor and the sensorhub

Embedded Software Developer

Low-power Bluetooth products for hospital real-time location systems, including patient-flow tracking and infant safety.

• •Championed Bluetooth Angle of Arrival: built the demo, presented it to management, and led the company to join the Bluetooth SIG
• •Led an early alpha-customer partnership with a silicon manufacturer, making Borda an early adopter of BLE AoA; the product line was rebuilt around it
• •Developed a low-power Cortex-M3 patient tag with a BLE bootloader for OTA updates
• •Led an end-of-line test environment with a GATT-caching app to speed up production testing
• •Mentored interns through interviews, training and project guidance
