About
We're looking for a Senior Embedded Software Engineer to drive software architecture across a diverse portfolio of embedded and connected products. This role blends system-level design, hands-on development with real hardware, and technical leadership within a growing engineering organization.
You'll work across software, firmware, and physical systems-shaping architecture, solving complex field issues, and mentoring engineers-while helping scale engineering practices and product quality.
This role includes limited travel (~4 weeks/year) for on-site development, troubleshooting, and industry events.
What You'll Do
Architecture & Technical Leadership

• Lead evolution of software architecture across embedded and connected systems
• Balance near-term delivery with long-term scalability, maintainability, and reliability
• Drive design reviews, technical standards, and cross-team architectural alignment

Hands-On Development & System Debugging

• Design, build, and debug software for embedded controllers, industrial systems, and HMIs
• Work directly with hardware, including custom embedded systems and industrial controllers
• Diagnose complex system-level issues spanning software, firmware, hardware, and real-world conditions

Testing & Quality Engineering

• Elevate automated testing practices across teams
• Design unit and integration testing strategies for embedded and application layers
• Lead development of automated test systems to improve coverage, reliability, and release velocity

Mentorship & Engineering Culture

• Mentor engineers through code reviews, pairing, and technical coaching
• Promote strong engineering fundamentals and pragmatic problem-solving
• Help build a culture of ownership, collaboration, and continuous improvement

Cross-Functional Collaboration

• Contribute as a senior member of a Scrum team spanning multiple product lines
• Partner with hardware, firmware, systems, and application engineers
• Manage competing priorities and context switching while maintaining high standards

AI & Engineering Productivity

• Help define and implement responsible use of AI in engineering workflows and products
• Establish practical use cases, guardrails, and best practices

Technical Environment
You'll work across a wide range of embedded and connected technologies, including:
Embedded & Distributed Systems

• CAN networks (J1939, CANopen, RV-C)
• Ethernet-based communication
• Cellular, Bluetooth, and remote diagnostics

Software & Platforms

• Embedded C, Python
• Mobile (iOS/Android), web interfaces, cloud systems, OTA updates

Control & Power Systems

• Motor control (BLDC, PMAC)
• Battery management systems (BMS)
• Power conversion (DC-DC, AC-DC, inverters up to 50 kW)

Vehicle & Industrial Integration

• Engine control, HVAC, PTO systems
• Hydraulic, welding, and air compressor systems

What You Bring

• Strong experience in embedded software development (C/C++ and/or Python)
• Experience with microcontrollers (e.g., STM, PIC) and low-level systems
• Background in system-level debugging across hardware and software
• Experience designing automated testing systems (embedded or hardware-integrated)
• Familiarity with MATLAB/Simulink for modeling or control systems
• Experience with industrial controllers or PLC-like systems (nice to have)
• Exposure to functional safety (SIL, ASIL) is a plus

Mindset:

• Systems thinker who enjoys working across hardware and software
• Pragmatic problem-solver comfortable with ambiguity
• Strong communicator and collaborator
• Invested in mentoring and growing others

Why This Role Stands Out

• Work on real-world machines, not just software
• Influence architecture, testing strategy, and engineering culture
• Balance hands-on problem solving with long-term system design
• Help shape how AI is responsibly integrated into engineering workflows
