Hapiko
Hapiko Senior+ Embedded/Firmware Engineer
Full-time embedded engineer, working at the sweet spot where real-time performance meets delightful user experiences.
About Hapiko Hapiko is a Brooklyn-based company building the future of play.
The Role Own firmware that runs on thousands of devices in people's homes. You'll work at the sweet spot where real-time performance meets delightful user experiences, making hardware that feels simple and just works.
You'll ship
Optimized C/C++ firmware for ESP-based systems
Real-time audio pipelines with low-latency capture and playback
Reliable OTA update systems for thousands > millions of devices already in the wild
Peripheral integrations across displays, printers, and sensors
Memory and power optimizations that squeeze every bit of performance
Production-ready firmware built for manufacturing scale
You're a Great Fit If You Have
5+ years building embedded systems with strong C++ skills
Deep experience with the ESP platform and toolchain
Hands-on audio data handling via I2S or PDM
Comfort with hardware debugging tools like oscilloscopes and logic analyzers
Experience integrating peripherals via SPI, UART, GPIO
Experience shipping consumer electronics or high-volume hardware
Worked with FreeRTOS and task scheduling
Applied basic audio DSP techniques like filtering and gain control
Built firmware for manufacturing test and factory workflows
Written Python scripts for tooling or test automation
Our Stack
Firmware: C/C++, ESP-IDF, FreeRTOS
Connectivity: WiFi and Web protocols
Peripherals: TFT displays, thermal printers, various sensors
Why Join Us We're a small, experienced team backed by top investors and moving fast. You'll own the entire firmware stack, influence hardware decisions from the ground up, and help build tech that feels magical and meaningful — while solving real embedded systems challenges.
If you love shipping firmware that powers delightful experiences, we'd love to talk to you!
Location: NYC only, On-site (flexible on WFH but we like to be in office the majority of the week) in our Brooklyn based office, close to most major train lines.
