DDR Silicon Validation Engineer - Bangalore, KA, India
Focus on silicon validation of DDR memory controllers and subsystems.
About the role
This role involves the silicon validation of memory controllers and subsystems at the full-system level, from pre-silicon environments through first-silicon bring-up and post-silicon qualification. This includes validating memory technologies such as DDR4, DDR5, LPDDR4/LPDDR5, and HBM.
What you'll do
- Participate in silicon bring-up of memory controllers, including board power-on, clocks, resets, boot flow, JTAG access, and firmware initialization.
- Develop and execute validation plans, firmware- and software-based tests, and system-level workloads to verify controller functionality, initialization, training, data integrity, performance, power management, reliability, and error handling.
- Create test content and low-level firmware using C, Python, and other scripting languages.
- Validate controller features including ECC, error injection, refresh, scrambling, encryption, address mapping, interleaving, arbitration, and low-power states.
- Measure and optimize memory bandwidth, latency, timing, calibration, and performance across supported configurations.
- Debug issues, correlate results between pre-silicon and silicon, and drive controller validation through product qualification and production readiness.
What you'll need
- 5 years of experience (Bachelor's degree) or 3 years of experience (Master's degree) in memory subsystem validation with hands-on exposure to validating memory technologies such as DDR4, DDR5, LPDDR4/LPDDR5, HBM, or related interfaces, controllers, and system integration.
- Understanding of memory controller architecture and protocols, including DDR4/DDR5, LPDDR4/LPDDR5, HBM.
- Knowledge of DFI, JEDEC standards, ECC/RAS, power management.
- Proficiency in C for firmware and low-level testing, plus Python, Perl, Shell, or similar scripting languages for automation.
- Understanding of embedded processors, memory maps, registers, interrupts, DMA, boot flows, and Linux or embedded operating systems.
- Experience debugging hardware/software interaction issues using logs, register dumps, waveforms, protocol traces, and failure signatures; and experience with lab and debug tools such as JTAG, logic analyzers, oscilloscopes, protocol analyzers, trace tools, and debug probes.
Nice to have
- Hands-on experience with first-silicon bring-up, evaluation boards, reference platforms, and post-silicon validation.
- Knowledge of embedded systems, hardware–software interaction, firmware, operating-system behaviour, board-level debug, system performance analysis, AMBA protocols, and silicon characterization.
- Familiarity with UVM/System Verilog, FPGA or emulation platforms, automated regression, CI, silicon characterization, and production or system-level qualification.
