Senior Connected Firmware Developer

Senior Connected Firmware Developer

Needham, MA 

The Opportunity

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.

What You'll Own

Connected Firmware Delivery

• 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.

Platform Implementation

• 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.

Design Review & Partner Governance

• 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.

Engineering Standards & Infrastructure

• 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.

Collaboration & Technical Growth

• 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.

What You'll Bring

Experience

• 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.
• 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).

Technical Expertise

• 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.
• Display technologies and embedded graphics/UI frameworks (a plus).

Education

• Bachelor's degree in Computer Engineering, Electrical Engineering, Computer Science, or a related discipline required.
