Apply for the
GTM Systems Engineer
role at
Black Forest Labs .
Our founding team pioneered Latent Diffusion and Stable Diffusion, and our FLUX models power creative tools, design workflows, and products across industries worldwide. We are building the commercial infrastructure to scale as rapidly as our technology.
What You’ll Pioneer You’ll build the nervous system of our revenue operations—billing infrastructure, enterprise GTM systems, and analytics infrastructure that supports real‑time visibility.
The Questions We’re Wrestling With
How do we accurately track and bill for API usage across millions of requests while handling edge cases we haven’t imagined yet?
What’s the right build‑vs‑buy calculus for a 50‑person company scaling to 150? (Stripe? Metronome? Custom?)
How do we create automated customer health scoring when our product is at the frontier and usage patterns are still emerging?
How do we design financial systems for a dual US/EU structure that doesn’t make our finance team want to quit?
What does "usage‑based billing" actually mean when customers use our API in ways we never anticipated?
How do we build support automation for self‑serve customers without losing the human touch that matters?
Required Experience Technical Skills
3–5+ years as a Software Engineer, Systems Engineer, or RevOps Engineer at a B2B AI or SaaS company
Programming proficiency: Python, JavaScript/TypeScript, SQL
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
API development: RESTful APIs, webhooks, OAuth, authentication protocols—you understand these as contracts, not just endpoints
Data pipelines: Proven experience building ETL/ELT workflows, data transformation, and warehouse integration
Billing systems: Familiarity with Stripe Billing, Metronome, Lago, Chargebee, or similar usage‑based billing platforms
Business & Domain Knowledge
Experience with usage‑based pricing, consumption billing, and complex contract structures
Understanding of multi‑jurisdictional business operations (US/EU structures a plus)
Track record of making build‑vs‑buy decisions and living with the consequences
How You Work
Cross‑functional collaboration: Translate fluently between finance, sales, and engineering speak
Business acumen: Connect technical solutions directly to revenue outcomes
Problem‑solving: Debug complex data flows and system integration issues independently
Communication: Explain technical concepts clearly to non‑technical stakeholders without condescension
Attention to detail: Ensure data accuracy and integrity because messy data leads to messy decisions
Ownership mentality: Identify problems and ship solutions without waiting for permission
Preferred Experience
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
What Success Looks Like Within 3 months Audit GTM systems, identify the biggest automation opportunities, build your first integration, and document where our revenue architecture breaks.
Within 6 months Manual billing tasks have dropped 70%. Usage‑based invoicing is automated. Finance, Ops, and GTM teams have self‑service dashboards they actually use. Make real build‑vs‑buy recommendations on subscription management.
Within 12 months Real‑time revenue visibility across all products and geographies. Scale 10x in customers without scaling ops headcount linearly. Billing errors under 1%. Build predictive models that detect churn and expansion before we need them.
