Flash Layer Firmware Engineer

This is a fully remote position, open to applicants in Germany.

📋 Description

• Overseeing the raw NAND interface and the device abstraction layer.

• Executing the ONFI-/Toggle protocol.

• Initiating the commissioning of new flash components and characterizing devices.

• Sustaining the Hardware Abstraction Layer (HAL).

• Developing and maintaining NAND flash interface firmware for ONFI 4.x/5.x and Toggle mode.

• Leading the integration of new flash vendors and generations, from initial datasheet assessment to production validation.

• Characterizing the behavior of flash devices.

• Innovating and refining calibration and read-retry strategies within the flash layer.

• Documenting vendor-specific behaviors and errata.

• Troubleshooting issues at the flash level.

⛳️ Requirements

• A degree in engineering, computer science, or a related field (BSc, MSc, or equivalent).

• Strong experience with Embedded C firmware at the hardware interface level.

• In-depth knowledge of NAND flash architecture and cell physics (Floating Gate, Charge Trap); familiarity with ONFI or Toggle-mode protocols at both the register and timing levels.

• Practical experience in commissioning or characterizing at least one real flash technology generation (SLC, pSLC, MLC, TLC, or QLC).

• Understanding of NAND reliability mechanisms: disturbance pulses, retention, Vth shift, and cell-to-cell interference.

• Proficiency in Python scripting for test automation and analysis of characterization data.

• Strong communication skills in English; proficiency in German is a plus.

🏝️ Benefits

• A collaborative team that supports each other, not just works together.

• An opportunity for your ideas — we appreciate proactive contributors.

• Flexibility that accommodates your lifestyle — with flextime and options for personal planning.

• A well-equipped work environment with cutting-edge EDA tools.

• Corporate benefits (e.g., Hansefit, Jobrad, and Pluxee).
