Principal Software Engineer

• Provide hands-on technical leadership for systems spanning IoT device control, smart home automation, energy, HVAC, water, and connected-device experiences. • Lead architecture and design for major software components, services, APIs, data flows, and integration patterns. • Help evolve existing monolithic systems into more modular, scalable, reliable, and maintainable systems. • Partner with product, firmware, platform, operations, and application teams to turn ambiguous needs into clear technical direction. • Mentor engineers at multiple levels and help raise the technical bar through design reviews, code reviews, technical guidance, and reusable patterns. • Drive cross-team collaboration and execution across multiple technical domains. • Evaluate new technologies, frameworks, and methodologies where they can materially improve product capabilities or engineering outcomes. • Reason across the full product stack, including backend services, databases, APIs, web and mobile experiences, device integrations, automation logic, and operational tooling. • Be an expert on system architecture, functionality, data flows, operational processes, and the tools needed to operate production systems effectively. • Provide technical thought leadership for major software components, systems, and features, earning alignment and driving adoption across teams. • Exercise strong engineering judgment: know when to move quickly, when to invest in a robust platform capability, and when to avoid unnecessary complexity. • Bring your ideas.

• Bachelor’s degree in Computer Science, Computer Engineering, a related field, or equivalent professional experience. • 15+ years of professional software development experience. • Proven experience designing, building, and delivering complex software systems. • Strong object-oriented programming skills; experience with C#/.NET or a similar object-oriented language is required; direct C# and .NET experience would be a major plus. • Significant database design, performance, and development experience. • Experience leading technical direction across teams and influencing architecture beyond a single project or codebase. • Experience mentoring engineers and helping develop people, practices, and reusable technical solutions. • Ability to select appropriate frameworks, architecture patterns, and technical approaches, then educate teams and drive adoption. • Strong analytical skills and a practical problem-solving mindset. • Ability to lead and influence across teams without relying solely on reporting authority. • Ability to reason across the full product stack, including backend services, data stores, APIs, device integrations, and web/mobile user experiences. • Strong understanding of object-oriented design, software development lifecycles, and long-term maintainability concerns. • Excellent communication skills, including the ability to explain technical tradeoffs to engineers, product owners, and business stakeholders.
