About the Role

This is the most senior engineering hire on the team, responsible for the complete technical architecture of a connected consumer electronics platform. You will ensure the integration of power electronics, embedded firmware, wireless communication, cloud infrastructure, and end-user applications into a unified product.

Responsibilities

  • Define and enforce interfaces across all system boundaries, from MCU firmware to end-user applications.
  • Ensure the system functions as a unified product, not a collection of subsystems.
  • Lead design reviews and make cross-functional trade-off decisions.
  • Drive technology selection, balancing custom solutions with off-the-shelf options.
  • Collaborate with electrical and mechanical engineers on hardware architecture decisions.
  • Ensure firmware architecture supports OTA updates, fault recovery, and diagnostics.
  • Own the regulatory strategy and ensure the design meets compliance requirements (UL, FCC, etc.).
  • Manage Bill of Materials (BOM) and supply chain risks, including component lifecycle and cost.
  • Define the cloud services layer, including device provisioning, telemetry, and data pipelines.
  • Architect data models and APIs for consumer-facing applications and support tools.
  • Design the end-to-end security and privacy model for the platform.
  • Champion cross-functional workflow practices and own the DevOps infrastructure (CI/CD, build systems, test automation).
  • Evaluate, onboard, and technically direct contract and full-time engineers.
  • Set technical standards and ensure integration of work from distributed contributors.
  • Shape the permanent engineering organization as the company grows.

Requirements

  • 8+ years of professional engineering experience spanning embedded systems, power electronics or analog hardware, IoT/connected devices, and cloud services.
  • Deep fluency in MCU-based systems (ARM Cortex-M or equivalent), real-time firmware design, peripheral integration, and hardware abstraction layers.
  • Working knowledge of power conversion topologies, thermal management, sensor front-ends, and mixed-signal design.
  • Experience with IoT security, including device identity, secure boot, TLS/DTLS, key provisioning, and encrypted OTA pipelines.
  • Experience architecting cloud infrastructure for device fleets (AWS IoT, Azure IoT, or equivalent).
  • Hands-on experience taking a hardware product through regulatory certification (UL, FCC, CE, or international equivalents).
  • Experience in early-stage companies, owning technical decisions with limited resources.
  • Ability to distinguish between critical day-one architecture decisions and those that can be iterated.
  • Strong cross-disciplinary communication skills to translate between product intent and engineering constraints.

About the Company

  • We are building a multi-component hardware platform where the quality of the experience depends entirely on the integration between physical devices, local intelligence, and cloud services.
  • The product surface is wide, the reliability bar is absolute (this is a product people live with daily), and the margin for “it mostly works” is zero.
