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 Software Engineer, Agentic Development, your mission is to 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.
What they're looking for
- 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
More about this role
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.
