Why work at Higgsfield AI?

Higgsfield AI is the fastest-scaling generative AI company in history, hitting $1B in annual revenue run rate, 30M+ users worldwide, 6M+ generations per day, and powering 390 of Fortune 500 brands.

We're building at the absolute frontier of AI-powered video creation and next-generation creative tools. Joining Higgsfield means becoming part of a high-impact team shaping the future of AI-native experiences, at a company that isn't just moving fast, but rewriting what fast looks like.

Who we are looking for
Everyone at Higgsfield is an A-player. We’re looking for teammates who bring:

A strong product sense and an understanding of how interface decisions affect conversion, retention and revenue.
The ability to design clear user states and in-product communication, not just build screens.
Broad context over narrow specialization: comfort working across product verticals and monetization mechanics.
Resilience and focus in a high-intensity startup environment, where priorities shift fast and the schedule isn’t always predictable.

What you will work on

Build the revenue-critical parts of Higgsfield products: paywalls, pricing pages, checkout and subscription flows used by millions of people.
Develop onboarding, upsell and in-product communication that drive conversion and retention.
Design and implement complex UI state logic across plans, limits, trials and payment states, where small mistakes are costly.
Run A/B tests and PLG experiments quickly, and work closely with analysts to turn data into product decisions.
Keep the interface fast and responsive, because every millisecond in the purchase flow affects conversion.
Ensure product quality through unit, integration and end-to-end tests for key payment and onboarding scenarios.

Your must haves

Experience building complex software and teaming up with others to get it done.
Strong communication, collaboration and commitment to completing projects.
Experience with payment integrations, checkout or subscription flows.
Experience with A/B testing, feature flags and product analytics.
Knowledge of CI/CD, bundlers, profiling and performance optimization.
Ability to get up to speed on new context quickly and take full ownership of a task.
Willingness to work in a fast-paced startup environment.
