Customer Support

Flux is taking the hard out of hardware. To do this, we’re building the world's first AI hardware engineer. Founded in 2019, our platform enables anyone to go from idea to manufacturable board using nothing more than a natural language prompt. This democratizes a process that has historically required years of specialized expertise.
We're going after a $15B+ electronic design automation market, backed by 8VC, Bain Capital Ventures, Liquid 2 Ventures, Outsiders Fund, Figma board member John Lilly, and GitHub founder Tom Preston-Werner. In February 2026, we closed a total of $37M in funding to accelerate that mission.
What happens when we unlock the ability for anyone to make hardware? We fundamentally reshape the world. That's our mission, and we're just getting started.

This is an opportunity to build a world‑class support function from the ground up. You’ll collaborate closely with product, engineering, and design to understand the platform deeply and ensure every customer interaction is positive. You’ll take ownership of support processes, develop knowledge resources, and represent the voice of the customer internally.

• Provide responsive, empathetic support via chat, email, and community channels, answering questions and troubleshooting issues to resolution.

• Become an expert in Flux’s design environment so you can guide users through workflows and new features.

• Investigate and triage technical issues, working with the engineering team to ensure timely fixes.

• Create and maintain help center articles, FAQs, and tutorial content to empower users to self‑serve.

• Analyze support tickets to identify recurring themes and propose improvements to product or documentation.

• Champion customer feedback within Flux and work cross‑functionally to advocate for user needs.

• Help define and refine support processes, metrics, and tools to scale our support operations as we grow.

• You have at least 2 years of experience in customer support, customer success, or technical support roles at a software company.

• You’re an excellent communicator with strong writing skills and a passion for helping people.

• You can translate complex technical concepts into clear, accessible language.

• You’re organized, detail‑oriented, and thrive in a fast‑paced startup environment.

• You’re comfortable using support software like ticketing and CRM systems.

• Bonus: Familiarity with electronics design, CAD or EDA tools, or experience supporting technical/developer audiences.

Impact-oriented: You don't feel done until real people are getting real value from what you built.

Ambiguity-native: You thrive in the undefined. Our work is full of half-mapped terrain, soft constraints, and ideas that shift under your feet. That energizes you. You constantly update your intuitions as you go, and are excited to discover new and better ways to attack challenges we're still finding words to describe.

Collaborative: You share your thoughts early and often, and welcome debate and creative collaboration. Flux is a deeply collaborative company, and we believe that the best ideas can only win if they're said out loud.

Convention-averse: Flux is an AI-first company, building AI tooling, using AI tooling. We constantly experiment with new tools, techniques, and processes. You feel an urgency to reimagine what your work looks like in this rapidly changing world, and you value critical thinking far above established conventions.

Ownership mentality: You are a self-starter, bias toward action, and care deeply about the team and community who lean on you and your work.

Thanks for reading! Prior experience with HW or Electronics is not required - except for our Hardware internships! If the roles above don’t fit you, we’d still love to have you in our network for upcoming opportunities. PS. We're always looking to meet Engineers who are interested in writing news, technical articles, or building tutorials.
