  • Drive architectural decisions across multiple teams and systems to ensure consistency, reliability, and developer velocity.
  • Identify systemic engineering problems early and lead solutions that create organization-wide leverage.
  • Partner with engineering leads to design and review critical systems before implementation.
  • Champion and standardize engineering patterns, tooling, and infrastructure best practices across the organization.
  • Evaluate emerging technologies and guide adoption when they provide meaningful value.
  • Mentor and develop senior and staff engineers, raise the technical bar, and help colleagues do their best work.
  • Represent engineering architecture in cross-functional discussions with product, operations, and leadership.
  • Contribute to hiring decisions and help shape engineering standards.

Desired Qualifications

  • Experience with industrial Internet of Things (IoT), edge computing, or real-time data pipelines, including MQTT, NATS, or OPC-UA.
  • Published Architecture Decision Records (ADRs), technical writing, or open-source contributions.
