Job Summary:

We are seeking a technically adept and detail-oriented engineer to join our Attack Lab. The role involves conducting & analyzing side-channel vulnerabilities, hardware-based fault injection attacks (e.g., voltage glitching, EM fault injection) and developing their countermeasures. The ideal candidate will have strong hands-on experience with electronic instrumentation, especially oscilloscopes, and a deep understanding of embedded systems including digital and analog circuitry.

Key Areas:

• Operate oscilloscopes, signal generators, and power supplies for precise waveform analysis.
• Analyze power traces and timing behavior of microcontrollers and SoCs under attack conditions.
• Develop scripts and automation tools for testbench control using Python, MATLAB etc.
• Document experimental setups, results, and technical findings for internal and external stakeholders.
• Collaborate with firmware and cryptography teams to assess and improve system resilience.
• Design and execute fault injection experiments (e.g., clock & voltage glitching, laser/EM perturbation).

Required Skills & Qualifications:

• Strong hands-on experience with oscilloscopes, logic analyzers, and signal generators.
• Solid understanding of digital electronics, microcontroller architectures, and communication protocols (UART, SPI, I2C).
• Familiarity with side-channel analysis and fault injection techniques is a strong plus.
• Proficiency in Python and C programming for automation and data analysis.
• Ability to interpret timing diagrams and waveform anomalies.
• Exposure to PCB design/debugging and soldering/rework skills.

Preferred Qualifications:

• Knowledge of cryptographic implementations and attack surfaces (AES, RSA, ECC)
• Experience with tools like ChipWhisperer, Riscure Inspector, or similar platforms
