Senior Embedded Software Engineer

Role Description

This is a full-time on-site role for a Senior Embedded Software Engineer at Mindlabs located in Hyderabad. Key responsibilities include but are not limited to:

• Design, build and support embedded software across QuecOpen, ESP32, STM32, and other MCU platforms for multiple product lines.
• Design robust, RTOS-based state machines for long-running, production-grade firmware.
• Implement and integrate peripherals such as GPIO, UART, I2C, SPI, ADC, PWM, sensors, and communication modules.
• Implement features such as sensor interfacing, timers, communication stacks, low-power logic, bootloaders, OTA, etc.

• Integrate with cellular/Wi-Fi/BLE modules and handle network lifecycle management.
• Build and maintain networking flows (TCP/UDP, MQTT, HTTP, TLS) for cloud-connected IoT devices.
• Work closely with hardware, cloud, and product teams to validate new boards, bring-up and validate prototypes, debug board-level issues and deliver complete embedded systems.
• Write clear documentation, participate in architecture discussions, code reviews, and contribute to continuous improvement.

• Support field testing and troubleshoot issues on deployed devices.

Skillset Requirements

Must-Have Skills:

• Strong expertise in Embedded C and real-time embedded development.
• Solid understanding of RTOS concepts: tasks/threads, priorities, queues, semaphores, timers, watchdogs.
• Experience with at least one major MCU platform such as ESP32 (ESP-IDF) or STM32.
• Hands-on experience with hardware interfaces: GPIO, UART, SPI, I2C, ADC, interrupts.
• Experience integrating and working with cellular modules (Quectel/SIMCom/u-blox) using AT commands or SDKs.
• Ability to work with vendor SDKs, proprietary APIs, and event-driven architectures.
• Understanding of TCP/UDP communication, MQTT/HTTP flows, TLS, reconnection logic.
• Strong debugging mindset using UART logs, firmware traces,logic analyzers, and systematic root-cause analysis.

Good to Have Skills:

• Experience with Quectel QuecOpen, Unisoc 8910DM, or SIMCom OpenCPU.
• Prior work with ThreadX, FreeRTOS, Zephyr, or similar environments.
• Experience in low-power lot device development, PSM/eDRX, or modem behavior patterns.
• Exposure to Modbus/RS485, sensor interfacing, CAN, or industrial protocols.
• Familiarity with embedded Linux concepts.
• End-to-end loT product or production firmware experience.

Qualification & Experience Requirements

• Bachelor's degree in Electronics, Electrical, Computer Engineering, or related field.
• Preferred: 3-5 years of embedded development experience.
• Minimum: 1-2 years of experience for strong candidates with solid embedded + RTOS fundamentals and real project experience.
• Freshers considered only if they have strong hands-on embedded portfolio (not hobby-level Arduino).

Perks working at Mindlabs

• A chance to work on some of the most disruptive and emerging technologies.
• Work culture which promotes freedom of creativity, exploration and emphasises on performance and responsibility above all.
• A great platform to face challenges, grow rapidly and establish independent professional feats
