About CapitalFlow

We are redefining how financial advice works in Germany.

The insurance and finance industry is one of the largest industries in the country – and technologically, it's stuck in 2005. Broken processes, cobbled-together tools, zero scalability.

CapitalFlow is the platform that advisors use live in customer conversations – a continuous system from data capture to the finished report. No concept. A product in daily use.

Over 800 paying users. 400% growth last year. 100% bootstrapped. And we're just getting started.

Responsibilities

You work directly with the CTO – not as a ticket-pusher, but as someone who independently implements features end-to-end. From conception to production deployment.

What this means in concrete terms: You take responsibility for entire feature areas, participate in architectural decisions, and see what you've built the next day in real customer conversations.

Qualifications

• At least 4 years of experience as a Fullstack Developer in the Node.js ecosystem
• Solid TypeScript knowledge
• Experience with PostgreSQL
• Next.js and/or NestJS – ideally both, one of them is mandatory
• You can implement features independently end-to-end – from conception to production deployment
• Basic knowledge of AWS

Bonus: Experience with monorepos (Turborepo), testing with Jest and/or Playwright

You don't need financial knowledge. You need the desire to build a complex product that changes an entire industry.

Benefits

• Real product, real users. What you build, people use the next day in real customer conversations. No feature graveyard.
• Ownership. Small team, short paths, big impact. No five hierarchy levels between you and a decision.
• Growth. 400% last year – and that's just the beginning. Those who take responsibility early grow with the company. Including the possibility of company shares.
• Office. Old building city villa near Hölderlinplatz in Stuttgart. Hybrid – but an office you like to be in.
• Equipment. MacBook, everything you need.
• Team. Joint events, trips, a team that builds together and celebrates together.

Our Process

Our process is short and direct:

• Get to know each other – short conversation to see if the direction fits
• Technical Interview – architecture and code
• Trial Day in the Stuttgart office – work together, get to know the team
• Offer & Start
