Principal Software Engineer

Your mission

- **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.
