Senior Embedded Software Engineer

Senior Embedded Software Engineer (Wireless & Hardware Systems) – W2 Contract

About the Company

A confidential, well-established product design and engineering consultancy is seeking an experienced Embedded Software Engineer to join its team on a W2 contract basis . The organisation delivers end-to-end product development services, turning complex ideas into fully engineered, production-ready solutions across embedded systems, electrical, mechanical, and software disciplines.

Projects span connected devices, IoT systems, and low-power embedded products where hardware and firmware are tightly integrated. Engineers work in multidisciplinary teams focused on building real-world, manufacturable solutions.

The Role

We are looking for a mid-to-senior Embedded Software Engineer to design, develop, and support firmware for low-power, connected embedded systems .

This role is ideal for engineers who enjoy working across both firmware and hardware-adjacent development , including close collaboration with electrical and hardware teams.

We are especially interested in candidates with experience in one or more of the following areas:

• Wireless / connectivity development (Bluetooth / BLE, Wi-Fi, Zigbee, cellular IoT)
• Hardware development or strong hardware collaboration experience
• Schematic review and understanding of electronic designs
• PCB design exposure or hands-on PCB development experience
• Battery-powered and low-power system design and optimisation

You will be embedded in a team working across full product lifecycles—from early design through to prototype, validation, and production support.

Key Responsibilities

• Develop and maintain embedded firmware in C/C++ for microcontroller-based systems
• Design firmware for low-power, battery-operated devices
• Work with hardware interfaces including I²C, SPI, UART, CAN, GPIO, and ADC
• Read and interpret schematics and component datasheets or Implement and support wireless communication features (BLE and other IoT protocols)
• Support debugging and validation using lab equipment such as oscilloscopes and logic analysers
• Collaborate closely with hardware, electrical, and systems engineers
• Contribute to firmware optimisation, verification, and system-level performance improvements

Required Experience

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or related discipline
• 7+ years of embedded systems experience
• Strong proficiency in embedded C/C++
• Experience with microcontrollers (e.g. ARM STM32, NXP, AVR, PIC, DSP platforms)
• Experience developing bare-metal and/or RTOS-based firmware
• Experience working with low-power embedded and battery-operated systems
• Ability to work effectively in hardware-facing engineering environments

Preferred Experience

• Exposure to PCB design tools and workflows
• Strong understanding of Bluetooth Low Energy (BLE) and IoT connectivity
• Ability to read and interpret schematics at system level
• Experience with battery systems, power management, or energy optimisation
• Familiarity with Silicon Labs BG22 or similar platforms
• Experience working in client-facing or consultancy-style engineering environments
• Ability to contribute to system architecture and design decisions

Location & Engagement

• W2 Contract Position (via engineering consultancy)
• Majority onsite working model in Long Island, NY area
• Some flexibility depending on project requirements
• Potential for long-term engagement based on performance and project needs

What’s on Offer

• Competitive W2 compensation aligned with experience
• Exposure to complex, real-world embedded product development
• Cross-disciplinary engineering environment (hardware, firmware, systems)
• Opportunity to work on full lifecycle product development
• Flexible working structure (including 9/80 schedule where applicable)
• Collaborative, engineering-driven culture focused on innovation

Why This Role

This is a hands-on embedded engineering role where firmware meets hardware. You’ll be working on complete systems—not isolated software components—contributing directly to how connected, low-power products are designed and brought to life.

Equal Opportunity

The employer is committed to building a diverse and inclusive engineering team and considers all qualified applicants without regard to protected characteristics.
