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

You’re the kind of builder who doesn’t feel finished until real people are getting real value from what you shipped. Impact isn’t a KPI to you, it’s the only reliable sign that the work mattered.

You thrive in the undefined. Agentic development is full of half-mapped terrain, strange constraints, and ideas that shift under your feet. That energizes you. You like turning nebulous problems into working systems and you’re happiest when exploring new approaches that weren’t obvious yesterday.

You share your thinking early, often, and without ego. Flux is a place where ideas circulate freely, the best one wins, no matter who said it, and you like working in that kind of environment. You enjoy asynchronous collaboration and you don’t mind jumping on a video call to hash out a knotty corner case.

You’re hungry to learn. Flux is an AI-first company that constantly experiments with new workflows, tools, and ways of working. You adapt quickly, improve your own processes, and bring a curiosity that moves the entire team forward.

You’ll succeed here if you’re a self-starter, you bias toward action, and you care deeply about the engineers and users who rely on your work. At Flux, velocity, curiosity, and teamwork aren’t slogans, they’re the floor you stand on every day.

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.
