Senior Full-Stack Engineer: Build UI & Industrial Controls

Toptal; Berkeley (CA); On-site; USD 150,000 - 210,000; Full time

Job summary

Toptal is seeking a Senior Full-Stack Engineer to build software that lets field engineers monitor and control large-scale industrial power systems. This is a hands-on, end-to-end role working across a modern web stack on the frontend and a Python/Go/gRPC backend that bridges into embedded control systems.

You will ship UI features, own them end-to-end, and collaborate with cross-disciplinary teams to commission and service physical equipment, including telemetry and Protobuf/gRPC pipelines.

Qualifications

• 6+ years of professional software engineering experience, including shipping production systems.
• Senior-level experience with React or another SPA-based web framework.
• Senior-level experience in Python, Go, gRPC, Protobuf, or industrial communication protocols (Modbus, DNP3, CAN, etc.)
• A genuine full-stack skill set — frontend UI work and backend plumbing
• Strong collaboration skills, user empathy, curiosity, and an ownership mindset.

Responsibilities

• Develop UI features end-to-end — from frontend views in React to backend APIs in Python/Go.
• Own features through the full lifecycle: requirements gathering, design, build, rollout, and user feedback.
• Collaborate closely with field engineers, firmware, mechanical/electrical engineers, product and design to commission and service physical equipment.
• Potentially extend scope into core infrastructure and control services within the embedded stack.
• Work with telemetry pipelines built on MQTT over WebSocket, and APIs built on Protobuf/gRPC.
