About Subflare
Our founder spent years in B2B SaaS sales speaking with thousands of companies across Europe. No matter the industry, he kept hearing the same frustration: sales only gets visibility after someone submits a form, when most of the buying journey has already happened. He started Subflare to solve that problem.
Today we have:
- A live MVP running on European infrastructure
- Our first paying customers onboarding
- Strong interest from companies across DACH, Benelux, and the UK
- A clear product roadmap shaped by real customer conversations
Now we are looking for Engineer #1 — not employee number twenty, to join our team of three. Our new team member will not be maintaining legacy code. We are in search of the first engineer, who will help shape the product, architecture, engineering culture, and long-term technical direction of the company.
The Honest Version of the Offer
We're a bootstrapped startup. That means cash is modest — and it also means ownership is real. We have more than 15 months of runway without raising additional funding, and every new customer extends that runway further.
Fully remote, full-time, async-first — a few hours of CET overlap (South America through Eastern Europe works well). Start whenever we're both ready. You'll work directly with the founder, with real ownership from day one. Our marketing website runs on Webflow, so your focus will be entirely on the product.
What You'll Build
- Behavioral data ingestion and real-time event processing
- The intent scoring engine (rules today, ML tomorrow as the data supports it)
- Backend services and APIs (Node.js / TypeScript or Python)
- Native CRM integrations (HubSpot, Salesforce, Pipedrive, Close and others)
- GDPR-native tracking and data governance
- Customer dashboards, attribution, alerts and analytics (React / Next.js)
- AWS infrastructure, deployment, monitoring and scaling
One of the most exciting parts of this role is that you won't just build AI models — you'll help build the dataset itself. Every customer interaction strengthens our behavioral graph, and that proprietary dataset compounds over time into a long-term competitive advantage. You don't need to be an ML expert today. But you should be excited about growing into one.
What we are Looking For
You probably have:
- 4+ years building production software
- Strong backend experience with Node.js / TypeScript or Python
- REST APIs and PostgreSQL
- Experience with data pipelines, event-driven systems or analytics platforms
- Third-party integrations and webhooks
- AWS and containerized deployments
- An ownership mindset — you enjoy taking ideas all the way to production
Bonus points if you've worked with:
- React / Next.js
- Applied ML (classification, behavioral prediction, scikit-learn)
- Kafka or similar streaming technologies
- Founding-stage startups
- Privacy-preserving analytics
- Products for Sales or RevOps teams
