Job description
We founded Flux to make atoms as malleable as bits. We want to take the hard out of hardware, to make it as easy for a teenager to build an iPhone as a website. We want to unleash the latent human potential held back by the high barriers to creating breakthrough physical products. We want to accelerate technological progress by making it possible for anyone, regardless of background or resources, to bring their best ideas to life in physical form.
We are building a real-time web-based collaboration platform to take hardware design into the future. Our first product is going to revolutionize the electronics prototyping and design workflow! We are a fully remote team (and always will be), spread across five continents and ten countries!
About the Role
Flux is building the world’s first AI Hardware Engineer, software that can design real, manufacturable electronics from a prompt.
As a Senior Product Engineer (Agentic Development), you’ll report to Jeff Wilde (Head of Engineering) and work within the Product team.
Your mission: build the brains of the system, agentic workflows, reasoning graphs, and integrations that help novice users move from idea to manufacturable hardware and seasoned electrical engineers learn from the hard earned battle scars from failed production runs of the past.
This role combines deep web engineering with AI systems design. You’ll work with Typescript and LangGraph across the Flux web app and backend platform, embedding intelligence directly into the design environment.
Responsibilities
Develop agentic reasoning capabilities in TypeScript (LangGraph).
Integrate AI behaviors into the Flux web app (React/Redux) and Chat UI.
Instrument telemetry and logging for runtime health, performance, and cost tracking.
Collaborate with product and electrical engineers to shape intelligent ECAD workflows.
Build and analyze evals; translate data into engineering decisions.
Actively shape agentic patterns, conventions, and best practices for the broader engineering org.
Required Qualifications
5+ years of software-engineering experience; 1+ year developing generative-AI or agentic systems.
Strong command of TypeScript, React, and Node.js.
Experience with LangChain, LangGraph, or equivalent orchestration frameworks.
Demonstrated success building asynchronous, distributed systems in production.
Experience integrating LLM-based systems into complex user-facing web products.
Excellent communicator comfortable in a fully remote, async team.
Experience at a startup or in 0→1 product environments.
Preferred Qualifications
Experience with retrieval systems, evaluation pipelines, or agent benchmarking.
Contributions to open-source AI/developer tools projects.
Familiarity with hardware design or ECAD concepts.
Background in applied ML, data-driven experimentation, or NLP.
Experience with distributed highly available systems that operate at significant scale.
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. Agentic development 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. We constantly experiment with new workflows, tools, and ways of working together. You feel an urgency to reimagine how we create and collaborate 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.
