Embedded Systems Internship

Kaptortech LLP is hiring an Embedded Systems Intern! Responsibilities • Develop zero-latency bare-metal C++ firmware for high-performance STM32 platforms based on ARM Cortex-M7 architecture. • Design and maintain DMA-driven circular ring buffers for continuous data acquisition and transmission. • Optimize computationally intensive mathematical algorithms for execution from Tightly Coupled Memory (DTCM). • Support firmware components used in hardware security proxy and aerospace telemetry applications. • Intercept, inspect, and analyze UART and RS-422 serial streams using suitable debugging and measurement techniques. • Use logic analyzers to troubleshoot timing, framing, throughput, and protocol-level issues. • Work with STM32CubeIDE or comparable bare-metal development workflows and collaborate closely with hardware-focused engineers. Requirements • Practical experience developing bare-metal firmware for STM32 microcontrollers, preferably ARM Cortex-M7 devices. • Strong C++ programming skills and an understanding of deterministic, resource-conscious embedded implementation. • Hands-on experience with DMA, circular buffers, memory architecture, and performance optimization. • Experience intercepting or debugging UART and RS-422 serial communication streams. • Ability to use logic analyzers for embedded debugging and signal investigation. • Arduino IDE-only experience is not suitable; candidates must have bare-metal or STM32CubeIDE experience. • Familiarity with custom KiCad PCB design or FPGA-based hardware acceleration using Verilog and lookup tables is a major advantage. • This is an unpaid, three-month hybrid internship based in Pune and is intended for candidates eager to work on demanding embedded systems problems.
