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.

Stale telemetry
Partial or failed data flows
Contribute to a cloud-hosted operator platform managing remote drone dock infrastructure

Extend workflows for:

Collaborate across backend, hardware, aircraft, and dock teams to define system contracts

Implement and maintain:

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

Strong understanding of distributed systems and API design, especially across hardware/software boundaries

Experience with security and access control, including:

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

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

Experience with geospatial or 3D technologies:

Experience with edge-to-cloud systems:
