About The Position

Texas Instruments' Precision ADC team is seeking a Digital Design & Firmware Engineer to help develop cutting-edge delta-sigma ADC products. You will work alongside world-class analog and mixed-signal designers building some of the highest-precision data converters in the industry. This is a uniquely cross-domain role that sits at the intersection of embedded firmware and digital hardware design, where your contributions span from RTL implementation down to C-based embedded firmware running on real silicon. In this position, you will contribute to the digital design of high-resolution delta-sigma ADC products, including digital decimation filters, calibration logic, on-chip state machines, and serial interface blocks, while also developing the embedded C firmware used in production silicon. You will work closely with analog designers, verification engineers, and applications teams to define register maps, debug hardware/firmware interactions, and validate end-to-end device behavior from bit-level RTL to system-level measurement. We value curiosity and a genuine desire to grow across domain boundaries. If you are an engineer who enjoys equally RTL and low-level C, this team will give you the environment and mentorship to do so. Products built here are trusted in medical, industrial, and instrumentation applications worldwide; the quality bar is high and the learning opportunity is exceptional.

Requirements

• Masters degree in Electrical Engineering or Computer Engineering
• 2+ years of relevant experience in digital design, embedded firmware, or a combination of both
• Proficiency in C for embedded or bare-metal environments
• Familiarity with RTL design using Verilog or SystemVerilog
• Understanding of digital logic design fundamentals
• Ability to solve problems using a systematic approach

Nice To Haves

• Experience writing embedded C drivers or evaluation firmware for mixed-signal devices
• Hands-on RTL design experience - combinational and sequential logic, FSMs, and synchronous design practices
• Familiarity with serial communication protocols used in precision ADCs (SPI, I2C, UART)
• Exposure to delta-sigma ADC architecture, digital filtering (sinc/decimation), or data converter fundamentals is a plus
• Familiarity with simulation and synthesis tools (ModelSim, Xcelium, VCS, or equivalent)
• Experience with scripting languages such as Python for test automation or data analysis
• Familiarity with functional safety standards (IEC 61508, IEC 60730, or ISO 26262) and associated design practices such as FMEA, diagnostic coverage, or safe failure fraction analysis is a plus
• Demonstrated strong analytical and problem-solving skills
• Strong verbal and written communication skills
• Ability to work in teams and collaborate effectively with people in different functions
• Ability to quickly ramp on new systems, processes, and design domains
• Ability to take the initiative and drive for results
• Strong time management skills that enable on-time project delivery

Responsibilities

• Contribute to the digital design of high-resolution delta-sigma ADC products, including digital decimation filters, calibration logic, on-chip state machines, and serial interface blocks.
• Develop the embedded C firmware used in production silicon.
• Define register maps.
• Debug hardware/firmware interactions.
• Validate end-to-end device behavior from bit-level RTL to system-level measurement.
