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.

About the role

We’re hiring a Growth Marketing Manager, Lifecycle/Email to own how users move through the Flux journey: signup, onboarding, activation, education, retention, reactivation, and long-term engagement.

Flux already has strong top-of-funnel momentum, with roughly 8k trials per month. The next growth challenge is helping more of those users reach real product value quickly, especially hardware entrepreneurs and engineering teams evaluating Flux for real design work.

This is a hands-on IC role to start. You’ll build the lifecycle and email engine from the ground up, working closely with growth, product, data, customer support, customer success, sales, and growth engineering. Over time, this role can grow into broader ownership of lifecycle and growth marketing.

The right person is analytical, systems-minded, and unusually strong at email execution. You should be comfortable finding lifecycle opportunities in the data, writing sharp copy for technical users, thinking through email UX and CTAs, running experiments, and shipping campaigns end-to-end. This is not a “send some nurture emails” role. We want someone who treats lifecycle email as a core product surface and can make it a meaningful growth lever.

What you’ll do

• Own lifecycle marketing across onboarding, activation, trial education, retention, reactivation, and product education.

• Build segmented user journeys based on behavior, lifecycle stage, product usage, intent, and activation signals.

• Create and test lifecycle campaigns across email, in-product messaging, nurture, activation prompts, and reactivation.

• Own lifecycle email execution end-to-end, including strategy, copy, layout, CTA quality, QA, launch, measurement, and iteration.

• Partner with product and growth engineering to improve onboarding, activation, trial quality, and retained usage.

• Define and track lifecycle metrics, including activation, time to first meaningful action, qualified trial conversion, retained usage, reactivation, and campaign-driven conversion.

• Turn product insights, customer feedback, support tickets, and user behavior into timely, useful communication.

• Build repeatable lifecycle systems instead of one-off campaigns.

• Improve segmentation, triggers, audience definitions, deliverability, list hygiene, and campaign measurement.

• Help users understand what Flux can do, why it matters, and how to get more value from the product.

• Work cross-functionally with product, growth, data, sales, customer support, and customer success to improve the full user journey.

What we’re looking for

• Experience owning lifecycle, growth, email, activation, retention, or PLG programs.

• Strong understanding of PLG funnels and self-serve user journeys.

• Excellent lifecycle/email craft, including copywriting, sequencing, CTAs, layout judgment, testing, and measurement.

• Ability to work with behavioral data, lifecycle metrics, segmentation, experimentation, and campaign performance.

• Clear, direct writing style, especially for technical or technical-adjacent audiences.

• Strong product judgment and user empathy.

• Comfort operating in ambiguity and building new systems from scratch.

• Ability to move quickly while still being thoughtful about measurement, deliverability, and quality.

• Strong cross-functional instincts and a high-ownership operating style.

• Scrappy, entrepreneurial growth mindset with the ability to prioritize, ship, learn, and iterate.

Nice to have

• Experience at a PLG, devtools, AI, design tools, CAD, EDA, hardware, or technical SaaS company.

• Experience marketing to engineers, developers, hardware teams, or technical creators.

• Hands-on experience with lifecycle tools, product analytics, marketing automation, ESPs, or experimentation platforms.

• Experience improving trial activation, onboarding, retention, reactivation, or expansion.

• Experience with deliverability, domain reputation, segmentation strategy, and list hygiene.

• Experience as an early lifecycle, growth, or email marketing hire.

• Experience partnering closely with product and engineering teams on onboarding or activation.
