Full-time

Here at HiViz Lighting Inc, our mission is to help first responders work more safely and effectively, so they can save lives. Our Engineering Team makes that possible by building smart, industry leading technology that powers the next generation of emergency vehicle lighting and smart systems.

• Create and maintain reusable firmware libraries for data bus interfaces, circuit control engines, bootloaders, and other core technology platforms
• Develop and maintain SDK libraries that make it simple to test, configure, and control HiViz firmware systems
• Build clear, thorough documentation for core technology libraries, including requirements, use cases, integration guides, and best practices
• Design embedded systems that make smart use of data structures such as queues, buffers, state machines, schedulers, and protocol-handling architectures
• Support the greater engineering team with product architecture, design reviews, feature prioritization, and roadmap planning
• Help ensure HiViz technology platforms stay aligned with product offerings, development timelines, and long-term feature needs
• Support internal teams, industry partners, and contractors as they integrate HiViz firmware libraries and SDKs into products and toolsets
• Support product integration across CAN and LIN data buses, BLE interfaces, and SPI and I2C peripherals
• Perform code reviews, build releases, OTA update support, and assist with management of digital company IP
• Participate in sprint planning and contribute to near-term and long-term product and feature roadmap proposals
• Drive test, validation, performance optimization, and release processes for new products, features, and core technologies

• Strong embedded firmware development experience, especially in C language, C99 or newer
• Experience with Python 3.9 or newer for toolset development, testing, automation, or support workflows
• Strong algorithm and data structure fundamentals, with the ability to make practical tradeoffs in real-time and resource-constrained embedded systems
• Experience designing or working with queues, circular buffers, ring buffers, schedulers, state machines, routing logic, protocol stacks, or similar embedded architectures
• Ability to evaluate time complexity, memory usage, CPU utilization, latency, and deterministic execution when designing firmware systems
• Experience improving performance, reducing memory footprint, or optimizing embedded systems for reliability and responsiveness
• Ability to create reusable, scalable firmware and SDK libraries that support multiple products
• Strong testing, debugging, and validation skills for embedded systems and related toolsets
• Comfort working in Linux terminal environments and using command line tools
• Hands-on experience with SPI, I2C, UART, CAN, LIN, BLE, and related embedded communication protocols
• Familiarity with CAN J1939, LIN J2602, Bluetooth GAP and GATT, and peripheral integration
• Understanding of PWM control of LEDs and automotive 12V electrical systems
• Clear communicator who can document technical systems, support cross-functional teams, and help partners integrate HiViz technology successfully
• Collaborative engineering mindset with the ability to connect product needs, architecture decisions, and implementation details

• Experience with RTOS environments such as FreeRTOS, Zephyr, VxWorks, QNX, or ThreadX
• Experience with task scheduling, priority queues, inter-task communication, synchronization, or deterministic real-time behavior
• Experience developing networking stacks, protocol implementations, bootloaders, robotics systems, automotive software, telecommunications systems, or other embedded systems where algorithmic thinking matters
• Coursework, project experience, or professional experience in data structures, algorithms, operating systems, computer architecture, real-time systems, or similar computer science fundamentals

• Mission-driven work:
  The technology you build helps keep first responders safe and emergency vehicles mission ready
• Technical impact:
  You’ll help shape reusable core technologies that scale across HiViz smart products
• Meaningful engineering challenges:
  Your work will involve practical algorithmic decisions around performance, memory, latency, communication, and reliability
• Collaboration:
  
  Work closely with engineering, product, internal teams, and industry partners to bring advanced systems to life
• Ownership:
  Contribute to architecture, firmware libraries, SDKs, documentation, releases, and long-term technology roadmaps
• Benefits:
  Competitive package including health insurance, paid time off, and 401k match
• At HiViz, embedded software is more than code, it’s the foundation of reliable, intelligent systems that help first responders do their jobs safely and effectively. If you’re ready to build technology with real-world impact, we’d love to hear from you.
