About the Job

Requirements

A degree in Computer Science, Computer Engineering, or Electrical Engineering, or equivalent experience.
Experience developing mission-critical embedded or edge-device software and corresponding test suites.
Proficiency in on-device systems languages such as C, Rust, or Go, and comfort debugging real hardware.
Real-world experience with device connectivity and Internet of Things protocols such as HTTP/REST, WebSockets, gRPC, MQTT, or TLS, and experience with at least one of embedded Linux services, RTOS-adjacent networking, or gateway/communications-controller software.
Experience building or operating telemetry, logging, or remote-diagnostics pipelines for fielded devices.
Strong software fundamentals, including clear interfaces, failure handling, maintainability, and testability.
Ability to multitask, prioritize, and work in a fast-paced, collaborative environment.

Responsibilities

Design, implement, and debug software for the Optimus offboard charger communications controller, including connectivity, device services, and control-plane interfaces between charger subsystems and external systems.
Own telemetry end to end, including deciding what to measure, buffering and transporting it under poor network conditions, and making it actionable for diagnostics, fleet health, and product improvement.
Build and harden over-the-air update capabilities, including download, authentication, staging, A/B or recovery paths, versioning, and safe application or rollback under power and network fault conditions.
Implement device coordination and site behaviors analogous to commercial charging, including multi-charger discovery, load sharing or power budgeting, local control when wide-area network connectivity is degraded, and APIs for site or factory systems.
Collaborate with electrical, controls, and robotics teams on requirements, interfaces, and bring-up of new charger hardware revisions.
Develop tools and diagnostics for factory programming, installation and commissioning, field debugging, and interoperability with third-party or internal backends.
Contribute to system architecture, automated unit, integration, and hardware-in-the-loop tests where applicable, and release practices that keep the charger fleet reliable.
Use fleet signals and field failures to drive continuous firmware improvements after launch.

Desired Qualifications

Experience with over-the-air or remote update systems, including secure-boot alignment, signed images, dual-bank or recovery mechanisms, and bandwidth- and power-aware updates.
Exposure to distributed or multi-node edge systems, including load sharing, device coordination, offline or degraded-mode behavior, or site controllers; experience in commercial electric vehicle supply equipment, industrial Internet of Things, energy, or robotics infrastructure is relevant.
Hands-on lab bring-up, reading schematics, and cross-functional debugging with hardware teams.

Job Description

We’re building humanoid robots for an age of abundance: machines that work at real scale so people can do more of what only people can do. Optimus only ships if we can charge it reliably, often, and without babysitting every unit in the field. The Tesla Energy / Optimus Charging software team is looking for a Software Engineer to own communications, telemetry, and over-the-air (OTA) software for the offboard Optimus charger so fleets stay healthy, observable, and updatable in factories, labs, and denser deployments, and so chargers coordinate with each other and site infrastructure when many units share power and space. The comms controller is the nervous system of that product. It aggregates device health and usage telemetry, manages reliable connectivity to local and cloud systems, delivers and verifies OTA updates safely, and participates in multi-device coordination (load sharing, discovery, and site-level control) similar to commercial charging installations. Our stack is diverse: device firmware and services, local networking, secure update pipelines, and fleet-facing telemetry. Pragmatism, willingness to dive into new codebases and hardware bring-up, eagerness to work with stakeholders (hardware, controls, robotics, compliance, manufacturing), and engineering leadership are key strengths we expect you to bring to the table.

Job Responsibilities

Design, implement, and debug software on the Optimus offboard charger communications controller: connectivity, device services, and control-plane interfaces between charger subsystems and the outside world
Own telemetry end-to-end: what we measure, how we buffer and transport it under poor links, how we make it actionable for diagnostics, fleet health, and product improvement
Build and harden OTA capability: download, authentication, staging, A/B or recovery paths, versioning, and safe apply/rollback under power and network fault conditions
Implement device coordination and site behaviors analogous to commercial charging, e.g. multi-charger discovery, load sharing / power budgeting, local control when WAN is degraded, and clear APIs toward site or factory systems
Collaborate with electrical, controls, and robotics teams on requirements, interfaces, and bring-up of new charger hardware revisions
Develop tools and diagnostics for factory programming, install/commissioning, field debug, and interoperability with third-party or internal backends as needed
Contribute to system architecture, automated tests (unit, integration, HIL where applicable), and release practices that keep a growing charger fleet reliable
Use fleet signals and field failures to drive continuous firmware improvements after launch

Job Requirements

Degree in Computer Science, Computer Engineering, Electrical Engineering, or equivalent experience
Ability to multi-task, prioritize, and work in an extremely fast-paced, collaborative environment
Experience developing mission-critical embedded or edge device software and corresponding test suites
Proficiency in systems languages used on-device (e.g. C, Rust, Go) and comfort debugging real hardware
Real-world experience with device connectivity and Internet/IoT protocols (e.g. HTTP/REST, WebSockets, gRPC, MQTT, TLS) and at least one of: embedded Linux services, RTOS-adjacent networking, or gateway/comms-controller software
Experience building or operating telemetry, logging, or remote diagnostics pipelines for fielded devices
Experience with OTA / remote update systems (secure boot alignment, signed images, dual-bank/recovery, bandwidth- and power-aware updates) is a strong plus
Exposure to distributed or multi-node edge systems- load sharing, device coordination, offline/degraded-mode behavior, or site controllers- is highly desirable (commercial EVSE, industrial IoT, energy, or robotics infrastructure are all relevant)
Strong software fundamentals: clear interfaces, failure handling, maintainability, and testability

About the Company

Tesla

Makes electric cars, robotaxis and grid batteries

Tesla makes electric cars and batteries that store power for homes and utilities, and it develops self-driving software and humanoid robots. In 2023, its Model Y became the first electric vehicle to rank as the world's best-selling car. Buyers order the Model 3 sedan, Model Y SUV, or Cybertruck pickup directly from Tesla instead of through dealers, and they charge on its Supercharger fast-charging network. It also sells Megapack and Powerwall batteries, runs a robotaxi service, and charges drivers a monthly fee for self-driving software that still needs their supervision. Tesla was founded in 2003, with Elon Musk as its lead early investor and a recognized co-founder, and it is based in Austin, Texas.
