Job Description

Censys Technologies Corporation is seeking a Senior Software Engineer (Frontend / Full Stack) to build mission-critical operator interfaces for autonomous drone operations. This role focuses on developing real-time, high-reliability systems that allow operators to monitor, control, and manage distributed drone fleets across cloud, edge, dock, and aircraft environments.

You will work on building modern web applications and real-time control systems that interact with live telemetry, mission state, and hardware integrations.

Key Responsibilities

Build and maintain modern web application features using React, TypeScript, Vite, and Tailwind

Design and implement real-time operator interfaces for:

• Drone telemetry
• Mission state and workflows
• Dock status and hardware health
• Alerting and safety systems
• Video and remote session management

Develop mission control systems, including:

• Pre-flight gating logic
• Mission state machines
• Operator-facing alerts and safeguards
• Integrate frontend systems with backend services using:
• REST APIs
• gRPC-Web / Protobuf / ConnectRPC
• WebSockets, SSE, and polling-based live data patterns

Build systems that handle unreliable connectivity, including:

• Degraded links (cellular / SATCOM)
• Stale telemetry
• Partial or failed data flows
• Contribute to a cloud-hosted operator platform managing remote drone dock infrastructure

Extend workflows for:

• Dataset processing
• Detection review
• Geospatial visualization
• Evidence export
• 3D / point cloud data
• Collaborate across backend, hardware, aircraft, and dock teams to define system contracts

Implement and maintain:

• RBAC and multi-organization access control
• Audit logging and SOC 2-aligned practices
• Use AI-assisted development tools effectively while validating outputs against system requirements, contracts, and safety constraints

Required Qualifications:

5+ years of professional software engineering experience building production systems

Strong experience with TypeScript and React, including:

• Complex state management
• Async workflows
• Performance optimization
• Maintainable component architecture

Experience building real-time or live-updating systems, such as:

• Dashboards
• Telemetry systems
• Monitoring tools
• Control interfaces

Experience integrating with backend systems using:

• REST

• Multi-tenant systems

Comfortable working in mission-critical environments where software affects:

• Hardware systems
• Operator decisions
• Field operations

Solid engineering fundamentals:

• Testing, debugging, observability
• Error handling
• Version control (Git)
• Clear communication

Practical experience using AI coding tools, with strong judgment around correctness, safety, and limitations

Preferred Qualifications:

Familiarity with UAS ground control systems (QGroundControl, Mission Planner, Auterion)

Familiarity with legacy PHP/Yii systems (for maintenance only, not primary stack)

Experience with Go, gRPC, Protobuf, NATS, PostgreSQL, or event-driven systems

Experience with:

• MAVLink, PX4, ArduPilot
• Drone telemetry and mission planning

Experience with real-time video systems:

• WebRTC, RTSP, HLS, LiveKit
