Principal Software Engineer

### What You’ll Do 
- **Architecture & Ownership** 
  - Lead the platform’s architecture across API, Brain/ROS, client/SDK, cloud services, UI, and deployment. 
  - Define and evolve architectural principles, module boundaries, interfaces, and quality bars. 
  - Establish guardrails for security, reliability, observability, and performance. 
  - Ensure decisions are documented and aligned across teams. 
 
- **Technical Leadership (with and through teams)** 
  - Shape the technical roadmap with Product/Stakeholders; define a clear “North Star” architecture. 
  - Mentor and coach Senior Engineers; drive high-quality design and code reviews. 
  - Tackle high-impact spikes/migrations hands-on while enabling teams to own delivery. 
  - Build consensus for cross-cutting changes and manage deprecation/upgrade paths. 
 
- **Platform & Infrastructure** 
  - Govern CI/CD, release strategy, versioning, and artifact management. 
  - Optimize containerization and on‑prem deployments (Docker, Compose, Ansible). 
  - Standardize logging, tracing, and monitoring; balance cost, reliability, and security. 
 
- **APIs, Data & Integration** 
  - Ensure contract-safe APIs and Protobuf schemas with strong backward compatibility. 
  - Oversee data modeling and migrations (Alembic) across services. 
  - Architect robust real-time communication (MQTT/WebSocket) and messaging patterns. 
 
- **Quality & Security** 
  - Drive a multi-layer test strategy (unit, integration, e2e) with meaningful coverage. 
  - Lead security reviews, secret and dependency management, and hardening of images/endpoints. 
 
- **Stakeholder Management** 
  - Collaborate closely with Product, Delivery, and Customer teams; translate requirements into architecture. 
  - Communicate decisions clearly and maintain transparent documentation.
