Senior Firmware Engineer at Helion in Everett, WA | USD150,000-194,000 | Kablio

Role

Description

firmware development

performance optimization

interface design

protocol implementation

board bring-up

toolchain improvement

Develop, test, and maintain firmware for real-time embedded systems used in machine control and diagnostics.
Optimize performance, reliability, and timing synchronization across distributed embedded systems.
Design and refine embedded command interfaces, configuration utilities, and automated test frameworks.
Implement and maintain low-level communication protocols (UART, SPI, I²C, CAN, EtherCAT, etc.).
Collaborate across disciplines to ensure firmware integrates seamlessly with high-level software and data systems.
Work closely with hardware and software engineers to translate system requirements into embedded designs.
Bring up new boards, sensors, and actuators — debugging with oscilloscopes, logic analyzers, and JTAG interfaces.
Rapidly prototype novel control and measurement concepts to support new machine architectures.
Contribute to continuous improvement of embedded toolchains, build systems, and test automation.

Requirements

Company

Overview

100M °C

Plasma Temperature

Achieved a plasma temperature of 100 million degrees Celsius, a critical milestone in fusion energy.

$1B

VC Funding

Received over $1 billion in venture capital funding to support their fusion energy research and development.

$5B

Valuation

Valued at over $5 billion in their Series F funding round, reflecting strong investor confidence in their fusion technology.

50 MW

Power Plant

Aiming to deliver a 50 MW fusion-generated electricity plant by 2028, marking a significant step toward commercial fusion energy.

Pursues a bold vision: taming the power of stars on Earth through fusion energy.
Develops magneto-inertial fusion technology, merging plasma at extreme speeds and capturing energy directly.
Pioneers in aneutronic fusion, recycling byproducts to generate helium-3, a sustainable fuel source.
Shifts from lab-scale to industrial-scale fusion with the Polaris device, supported by legal agreements.
Aims for rapid iteration with reactor designs capable of one pulse per second, enabling modular fusion systems.

Culture + Values

Build with urgency
Take ownership
Execute rigorously
Deliver hard truths

Environment + Sustainability

$500M in 2021

Investment Figure

Raised $500 million in 2021 to accelerate the development of their net-electricity target device, Polaris.

100M°C

Plasma Temperature Achievement

Achieved a milestone by heating plasma to 100 million degrees Celsius in June 2021.

500 MWe

Fusion Plant Capacity

Partnered with Nucor to deploy a 500 MWe fusion plant, enabling zero-carbon baseload power for steelmaking.

Committed to generating zero‑carbon electricity from fusion
Pulsed non‑ignition fusion approach avoids steam turbines and cooling towers by direct electricity capture
Supporting right‑sized regulation to enable safe and rapid fusion deployment
Applied for nitrogen‑based fire suppression and borated‑polyethylene shielding for safety and environmental protection
