BlackForestLabs
Growth Engineer New Freiburg (Germany), San Francisco (USA)
BlackForestLabs, San Francisco, California, United States, 94199
We're the ~50-person team behind FLUX.1, FLUX.2, and Stable Diffusion—models with 400M+ downloads that have fundamentally changed what's possible in visual creation. Our founding team invented latent diffusion and continues to push the technical frontier.
We are hiring for a Software Engineer on the growth team to focus on our self-serve customers (consumer, prosumer, and self-serve B2B) and product-led growth. You'll operate at the intersection of engineering, product, and marketing.
You'll join our small, high-impact growth team to build the infrastructure that turns research leadership into market dominance—establishing the loops, community, and systematic engagement that make BFL the obvious choice for anyone building with visual AI.
The work will be a mix of novel channel creation and optimization on our channels already at scale. You'll operate across the full range of our metrics — including driving awareness, acquisition, retention, revenue, and referral.
What you’ll do Build the frontend experiences that make FLUX sticky, shareable, and self-growing - from landing pages that convert to mini-tools that go viral.
Ship User-Facing Growth Infrastructure
Ideate and implement (both frontend and backend) full growth features and experiments to run that have a significant impact on user acquisition, e.g., by driving product virality
Build and optimize activation flows, onboarding experiences, and subscription funnels that convert
Set up a pricing experimentation system and use it to iterate on pricing
Create interactive homepages, SEO-optimized showcase pages, and developer galleries
Spin up viral mini-tools and demos that show FLUX capabilities (think "try it now" experiences)
Design and ship competition landing pages, hackathon microsites, and community showcases in hours not days
A/B test UI flows, messaging, and conversion points to find and scale what works
Create Shareable Moments
Build "Built with FLUX" galleries with beautiful UI that developers want to share
Design social share mechanics, embeddable widgets, and attribution flows
Create interactive demos and playground experiences that drive organic distribution
Prototype product-led growth loops: referrals, badges, showcase features
Own the Full Stack (Frontend to Growth)
Write engaging copy that converts - landing pages, CTAs, tooltips, emails
Design beautiful interfaces (or work closely with design when available)
Instrument analytics to track every conversion point and user flow
Move fast: identify bottlenecks in funnels, ship fixes same day
You might be a fit if you bring
Strong full-stack engineering skills (you can either be backend leaning, frontend leaning, or half‑half)
Strong product sense
Interest in growth and the business side of things
Experience with signup and onboarding conversion rate optimization
(Bonus) Experience with performance marketing optimization
(Bonus) Experience launching or growing products
(Bonus) Competence with analytics and experimentation tools
Nice-to-haves
Prior experience in PLG or developer‑tool startups
Familiarity with growth analytics stacks
Portfolio of side projects, interactive demos, or viral tools you've built
What we offer at BFL
High agency environment - challenging problems, fast learning, direct impact
Employee‑friendly equity terms (extended exercise)
A lot of learning and growth opportunities
We offer visa sponsorship and will help you relocate to San Francisco or Freiburg
