The ideal candidate brings deep expertise in real-time system design, mission/state machine logic, telemetry and command handling, and firmware verification — building on top of the driver interfaces the Platform Firmware Engineer exposes. Experience in aerospace, defence, avionics, or other mission-critical electronics domains will be highly valued. Responsibilities • Design and implement Super loop and RTOS-based application firmware: task scheduling, inter-task communication, timers, interrupts, mutexes, queues, and memory management. • Develop application-level firmware, mission logic, and state-machine behavior on top of the driver layer. • Implement real-time data acquisition pipelines: sensor read, engineering-unit conversion, calibration, and filtering. • Implement telemetry packetization, CRC framing, and command decode/validate/execute/reply flows. • Implement fault detection and fault management logic, including safe-state transitions and event logging. • Perform firmware integration and system-level debugging at the application/mission-logic level. • Review schematics and hardware designs from a mission-logic and data-flow perspective. • Support design verification activities from an application-behavior perspective. • Prepare firmware design documents, test procedures, debug reports, and release notes. • Participate in unit testing, integration testing, and firmware release management and version control. • Collaborate with the low-level Firmware Engineer, hardware, FPGA teams. Qualifications • Role Overview • Department Engineering / Embedded Systems / Avionics & Defence Electronics • Employment Type Full-time • Experience 6 - 15 Years of relevant embedded firmware experience • Qualification B.E. / B.Tech / M.E. / M.Tech — Electronics, Electrical, Embedded Systems, Instrumentation, Computer Science or related discipline • Domain Preference Aerospace, Defence, Avionics, Space, or Mission-Critical Systems Required Skills • Core programming - strong proficiency in Embedded C , Python or VB.NET knowledge is an advantage. • Solid understanding of RTOS-based firmware development, with working knowledge of the underlying MCU architecture (memory map, interrupts, timers) the application runs on. • Experience designing application logic that consumes a driver interface rather than accessing registers directly. • Supported MCU Platforms • Application-level familiarity with ARM Cortex-M series (STM32, NXP, Microchip SAM / PIC32) • Renesas, Infineon, or other equivalent 32-bit MCU platforms, as consumed through the platform team's BSP • RTOS Concepts • Task/thread creation, priorities, and scheduling • Semaphores, mutexes, queues, and mailboxes • Software/hardware timers and ISR-to-task communication • Stack and heap management; memory safety • Communication Protocols • Application-level framing and command/telemetry design over UART, SPI, I²C, CAN / CAN-FD • RS-232, RS-485, Ethernet, USB — protocol-level packet design and validation • Debugging & Tooling • JTAG, SWD, breakpoints, watchpoints, memory views, and trace tools for application-level debugging. • Working knowledge of IDEs/toolchains: STM32CubeIDE, MPLAB X, Code ,GCC, Eclipse. • Source control: Git. • Ability to read schematics and datasheets to understand the data available from the driver layer. Preferred Skills • Prior experience in mission-critical embedded systems. • Familiarity with MISRA C, MIL-STD requirements, or RTCA qualification processes. • Experience with firmware upgrade mechanisms, CRC verification, watchdog strategy, and fail-safe design at the application/state-machine level. • Knowledge of high-reliability and fault-tolerant embedded design practices. • Real-time data acquisition, control systems, sensor interfacing, or actuator control experience. • Python, VB, or scripting skills for test automation and utility development. • Exposure to static analysis tools, unit testing frameworks, and CI for embedded firmware. • Tools & Technologies • Programming: Embedded C (primary), C++ (preferred), Python scripting • RTOS: FreeRTOS. JD — Application Firmware Engineer • Debug Tools: JTAG, SWD, ST-Link. • Lab Instruments: DSO, Logic Analyzer, Protocol Analyzer, Multimeter, Function Generator. • Protocols: UART, SPI, I²C, CAN / CAN-FD, Ethernet, USB, RS-232, RS-485. • Version Control: Git. • Documentation: Design documents, test procedures, traceability docs, technical reports • Key Competencies • Embedded System Design • Strong Firmware Fundamentals • Hardware-Software Integration • Hands-on Debugging & Problem-Solving • Documentation & Process Discipline • Cross-functional Collaboration • Quality, Reliability & Safety Focus • Documentation of source Code.
