Senior Embedded Software Engineer

Company DescriptionMindlabs is a fast-growing deeptech startup building intelligent, reliable infrastructure for the physical world. We specialize in real-time sensing systems for cold chain, logistics, and industrial environments — combining rugged hardware, wireless connectivity, and cloud-native software. Our mission is to reduce global inefficiencies like cold chain wastage through technology that’s invisible, scalable, and resilient. Founded by engineers from IITs, we're a product-first company with full-stack control — from PCB to platform — and a culture obsessed with field reliability, quality, and long-term impact.Role DescriptionThis 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 RequirementsMust-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 IoT 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 IoT product or production firmware experience.Qualification & Experience RequirementsBachelor’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 MindlabsA chance to work on some of the most disruptive and emerging technologiesWork culture which promotes freedom of creativity, exploration and emphasises on performance and responsibility above allA great platform to face challenges, grow rapidly and establish independent professional featsTo know more about us, please visit www.mindlabs.cloud
