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

Flux is building the default starting point for hardware design. We are hiring a Senior Product Marketing Manager to own positioning, narrative, and launches so Flux is consistently understood and compelling across every surface and channel. You will report to the COO and work closely with product, design, and the GTM team.

What You’ll Do

• Own positioning and messaging: value props, proof points, competitive framing, and copy standards

• Lead product launches end-to-end: briefs, narratives, assets, timelines, and channel coordination

• Align GTM channels around one story: paid, SEO, lifecycle, social, community, and sales surfaces

• Define segmentation and packaging messaging as Flux evolves (example: Starter vs Pro)

• Build reusable systems: messaging libraries, launch playbooks, FAQs, objection handling, and copy blocks

• Partner with product and design to improve key conversion surfaces where narrative meets experience

What You’ll Bring

• Proven PMM experience for technical users (PLG, devtools, technical SaaS, or similar)

• Exceptional writing, editing, and narrative skill with strong taste

• Track record of running launches and coordinating across multiple teams

• Ability to align channel owners without owning their execution

• Comfort operating in ambiguity and building systems from scratch

Preferred Qualifications

• Experience marketing to hardware engineers or adjacent technical communities

• Experience with segmentation and tier narratives (Starter vs Pro, packaging, upgrades)

• Background in fast-shipping product orgs with frequent launches

• Experience partnering closely with lifecycle marketing and onboarding systems
