GTM Systems Engineer
Quick Summary
much of it doesn't exist yet. Billing infrastructure that doesn't break at scale Our business model is deliberately complex: usage-based API pricing, enterprise licenses, self-serve Playground flows,
Headquartered in Freiburg, Germany with a growing presence in San Francisco, we’re scaling fast while staying true to what makes us different: research excellence, open science, and building technology that expands human creativity.
We've built the foundation models that power FLUX and transformed how the world generates images—now we're figuring out how to build the commercial infrastructure that can scale as fast as our technology.
This isn't your typical RevOps role, and it's not pure engineering either. It's the technical architecture of our business itself: the systems that turn API calls into revenue, transform messy multi-jurisdictional data into clarity, and automate what currently requires 10 people to do manually.
You'll be building the nervous system of our revenue operations—but we're honest: much of it doesn't exist yet.
- Billing infrastructure that doesn't break at scale
Our business model is deliberately complex: usage-based API pricing, enterprise licenses, self-serve Playground flows, dual US/German entities. You'll design systems that handle this without requiring an army of humans to intervene. How do we track API consumption accurately? How do we automate invoice generation across jurisdictions? How do we recognize revenue correctly when products and pricing are constantly evolving? - Enterprise GTM systems that actually talk to each other
Right now, data moves through too many hands. You'll architect integrations between CRM, billing, contracts, and finance—building the workflows that turn enterprise sales from a manual slog into something elegant. Quote-to-cash shouldn't take weeks. Contract amendments shouldn't require spreadsheets. We need systems that scale with ambition. - Analytics infrastructure that surfaces truth
We're flying fast, which means we need instruments. You'll build the data pipelines and dashboards that show us what's actually happening: consumption patterns, churn signals, expansion opportunities. Not vanity metrics—the kind of real-time visibility that changes how we make decisions.

- CRM expertise: Hands-on experience with cloud-based CRMs such as Attio, Salesforce, or HubSpot
- Integration platforms: Experience building with Workato, Zapier, Tray.io, or similar iPaaS tools

- Ownership mentality: You identify problems and ship solutions without waiting for permission
Nice to Have
~1 min read- Experience at a high-growth startup scaling from $1M to $100M+ ARR (ideally during the messy middle)
- Familiarity with API-first or usage-based products
- Experience with data visualization tools (Tableau, Looker, Metabase)
- Knowledge of sales tax, VAT compliance, and multi-currency billing
- Prior experience navigating dual US/EU entity structures
- Obsessed: We build beautifully crafted, scientifically rigorous products by deeply understanding problems from first principles; and never shipping anything we’re not proud of.
- Low Ego: Prioritizing the best idea over personal ownership, where titles hold no authority, credit is shared, and no task is beneath anyone.
- Bold: We ship bold ideas early, improve fast, and take ambitious bets, without sacrificing quality for speed.
- Kind: We treat each other with genuine care, speaking directly and kindly even when conversations are hard.
If this sounds like work you’d enjoy, we’d love to hear from you.
