Customer Success Engineer

Job Description Why Flux 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. The Role This is a unique opportunity for a technically minded operator operate as one of the first customer success engineers in the company. You’ll partner closely with product, design, engineering, and growth teams, but your focus will be on empowering customers to successfully design electronics with Flux. You’ll deliver training, troubleshoot issues, and turn customer feedback into actionable insights that shape our roadmap. What You’ll Do Provide technical onboarding and training for new customers, guiding them through Flux’s design environment and ensuring they achieve their first “aha” moment quickly. Diagnose and resolve electrical design challenges and application issues, leveraging your EE expertise to guide users to successful outcomes. Develop educational resources—docs, videos, sample designs—to scale knowledge sharing across our community. Gather and synthesize customer feedback to inform product priorities and improve our platform. Collaborate with engineering and product teams to triage bugs and drive customer‑requested features. Build and maintain strong relationships with customers, acting as their trusted advisor and champion within Flux. Analyze usage data to identify patterns of friction or churn and work with cross‑functional teams to address them. What You’ll Bring You have a degree in Electrical Engineering (or a related field) and experience designing PCBs or electronic systems. You’ve spent at least 3 years in customer-facing technical roles such as customer success, solutions engineering, or field applications engineering. You are passionate about helping people and can translate complex technical concepts into clear, actionable guidance. You’re comfortable troubleshooting circuit designs and explaining trade‑offs to both technical and non‑technical stakeholders. You thrive in ambiguous, fast‑paced startup environments and enjoy wearing multiple hats. Excellent written and verbal communication skills with a knack for building rapport. Bonus: Experience using Flux or other hardware design tools, scripting or programming experience, and a passion for the maker community. Profile 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. #J-18808-Ljbffr 6AM City, LLC
