Senior Embedded Systems Engineer

We are hiring a Senior Embedded Systems Engineer. You will develop firmware for our family of baby and adult sleep devices, creating new features and fixing issues in microcontroller code written with the ESP-IDF and running FreeRTOS. What You’ll Do Dig into our embedded architecture and tools through team walkthroughs and independent exploration, providing clear observations. Own and ship fixes and features, using AI to accelerate delivery. Use and understand tools for observability. Build strong working relationships with peers across mobile, backend, product, QA, and other teams. Thoroughly understand the system architecture, including interactions with the mobile app and cloud backend. Learn the business drivers and apply sharp judgment to prioritize work. Own and ship complex fixes and features, refactors, and process improvements. Improve observability by developing dashboards and tools, enhancing firmware as needed. Lead the design and rollout of new product firmware or large‑scale refactors. Mentor teammates and model pragmatic, high‑quality engineering decisions. Drive embedded improvements that elevate reliability, stability, and developer experience. Build reusable modules, scripts, and patterns that increase engineering consistency. Maintain a customer‑centric focus throughout all work. What You’ll Bring 7+ years of embedded engineering experience, with deep expertise in C development on resource‑constrained MCUs running an RTOS, BLE/Bluetooth, Wi‑Fi, SPI, I2C, I2S, LEDs, and familiarity with Jira, Git/Github, GDB, Make/CMake, Python, schematics, part selection, and datasheet interpretation. Track record of working at the border between hardware and software, delivering high‑quality consumer products in cost, schedule, and MCU‑resource‑constrained environments. A passion for evolving production firmware by improving structure, testability, and maintainability without introducing regressions. Experience writing automated tests and processes, and an understanding of when they should be applied. A desire for elegance and simplicity, following the principle of “do the simplest thing that can possibly work.” Judgment and humility, self‑awareness, and the ability to raise concerns when necessary. A pragmatic approach, recognizing that new technologies are not always the best solution. A collaborative spirit that elevates those around you. Clear communication skills, able to explain complex concepts simply. Bonus Points Experience with Claude code, audio‑specific development, PCB design tools (Altium), ESP32, FreeRTOS, integration with AWS, and large‑scale deployment. Benefits 100% paid medical, dental, and vision insurance for employees (80% for dependents, including domestic partners). 16 weeks of fully paid parental leave. 16 free therapy sessions for you and one other adult in your life. Financial support for family planning. Remote office with monthly internet reimbursement. Friends & family discounts on Hatch products.
