Senior Connected Firmware Developer

SharkNinja•Needham, MA

2d•Onsite

About The Position

This is the hands-on connected-firmware role at SharkNinja — you write the code that makes our products connect. Two things sit with you: the connected features SharkNinja deliberately keeps in-house (wireless connectivity, device provisioning and pairing, over-the-air updates, and the differentiated connected experiences that set our products apart), and the platform layer other connected programs depend on (connectivity stacks, provisioning code, and shared app/cloud integration components). The connectivity interface contracts, app/cloud API boundaries, and wireless platform selection criteria are already defined. Your work is building to those decisions: production connected-feature code end to end, plus the reference implementations that prove the architecture out for every program and partner that follows.

Requirements

5+ years of embedded software and firmware development, with meaningful depth in wireless connectivity or connected-device features.
Production connected firmware you've delivered and shipped in commercial products.
Building to an architecture defined by others — implementing connectivity stacks, provisioning flows, or app/cloud integration from documented interface contracts.
Strong embedded C; C++ on resource-constrained platforms.
Wireless connectivity technologies: Wi-Fi, Bluetooth/BLE, Matter, Thread, Zigbee.
Device provisioning, pairing, and companion app integration: BLE GATT, Wi-Fi onboarding, cloud device registration and authentication.
Real-Time Operating Systems (RTOS).
Git-based workflows, CI builds (gcc, CMake, headless), unit testing (Ceedling or equivalent), static analysis.
Debug on target hardware — oscilloscopes, logic analyzers, JTAG/SWD, trace.
OTA update mechanisms and device security fundamentals for connected products.
Bachelor's degree in Computer Engineering, Electrical Engineering, Computer Science, or a related discipline required.
Ownership and follow-through
technical rigor
clear written and verbal communication
collaboration across hardware, cloud, and mobile
standards discipline under schedule pressure.

Nice To Haves

Consumer electronics, IoT devices, smart home products, or comparable connected high-volume products (preferred).
CI/CD, automated testing, or build infrastructure for embedded systems (strongly preferred).
Reviewing or integrating code from external development partners (an advantage).
Display technologies and embedded graphics/UI frameworks (a plus).

Responsibilities

Design, implement, and debug production embedded firmware for connected consumer and home appliance products.
Connected features end to end — requirements clarification, implementation, unit test, integration, and release support.
Building in the retained areas: wireless connectivity, device provisioning and pairing, OTA, and differentiated connected experiences.
Development against the connectivity architecture, interface, and app/cloud integration standards — adopting platform components rather than rebuilding them.
Implement the defined reference architectures and reference implementations — Bluetooth/BLE, Wi-Fi, Zigbee, Thread, and Matter stacks, plus provisioning and pairing code — reused across product categories.
Build and maintain shared connectivity and app/cloud integration components, including BLE GATT profiles, Wi-Fi onboarding, and cloud device registration.
Build to the defined interface contracts and platform decisions.
Prototype new connectivity and app-integration technologies to de-risk decisions ahead of program commitment.
Participate in technical design reviews for internal and partner-developed connected firmware.
Review partner-delivered connected code and integrate it against SharkNinja standards.
Turn architectural intent into working reference code and shipped connected features that partners and other programs can build against without interpretation.
Support partner technical capability assessments for wireless and app-integration subsystems.
Write unit tests and maintain code coverage against the standard applied across internal and supplier code; resolve static analysis findings, with no unresolved critical or high-severity issues at release.
Build and maintain CI pipeline, static analysis configuration, and interoperability test-harness infrastructure for owned connected features and platform components.
Verify the reproducibility standard in practice — confirm that source, toolchain, and build manifest deliverables actually rebuild the shipping binary.
Work in feature branches with PR-gated merges, ticket-linked commits, and commit messages sufficient to generate release notes.
Work under the technical direction of Principal Engineers on connected platform capabilities and design review, building toward broader architectural scope over time.
Bring up firmware on target hardware and debug hardware-software-app integration issues with Hardware Engineering, Cloud, and Mobile App teams.
Support certification activities — Bluetooth SIG, Wi-Fi Alliance, Matter — with hands-on testing and issue resolution.
Coordinate with firmware engineers in other regions to drive continuous improvement.
