As the FELS Group, we exist to make wealth building through a GmbH as simple as a single click. The FELSFO app, FELS Family Office's digital platform, is where that happens: it brings together investments, professional brokerage, and automated securities accounting in a single solution – instead of fragmented individual tools and manual processes. This includes FELS Broker, through which more than 500 GmbH owners already trade across 150+ markets, WEPA, our automated securities accounting engine with DATEV export, and the full-service offering of FELSEN Steuerberatung for bookkeeping, annual financial statements, and tax returns.
This is how we make wealth building accessible and efficient – our ambition: more profit, more control, more freedom for our clients. For all of this to keep running smoothly going forward, we're looking for a CTO to join as soon as possible who thinks in systems and brings the technological foundation for that promise.Technology is more than code to you – it's a strategic tool to move a company forward. As CTO, you own the technology vision for the entire FELS Group: you set the strategic direction, advise our engineers, and act as the go-to sparring partner for management on technology decisions.
The focus is less on hands-on coding day-to-day, and all the more on value-creating impact across the whole group. Our stack: TypeScript/Node, MySQL/Prisma, Python, Kubernetes, and Ruby/Rails/Rust – a real production system, not a purely conceptual role. Background: Director-level experience from a regulated fintech company or equivalent. Financial acumen: Solid financial and tax knowledge or a strong interest in and fascination with the finance and tax sector.
Technical foundation: Enough hands-on experience of your own – for example with mature, production systems, architecture decisions, and API integrations – to soundly assess technical decisions, even without coding day-to-day yourself. Business acumen: You understand the business context and value contribution of technology, not just the technology itself. Language skills: Business-fluent German, English as the working language in code and technical documentation.
Nice to have: Experience with ledger or booking engines and securities, ETL and broker or bank data feeds, DATEV or other accounting-software integrations, data protection, and German tax and accounting standards (HGB, InvStG, § 8b KStG) or a tax advisory or audit (WP) firm. A role with strategic value contribution across the entire FELS Group, technology ownership, and direct influence on business development Very high degree of autonomy in technology strategy and architecture decisions Competitive salary with bonus and equity participation Hybrid work, based in Frankfurt/Berlin Close, uncomplicated coordination with the General Manager and management instead of long decision paths, and an agile way of working within the team A highly demanding environment at the intersection of FinTech, tax law, and capital markets Full-time, permanent employment, flexible hours Long-term development perspective in a growing family office environment Subject-matter depth with leverage: Securities accounting, tax law, and trading meet modern technology – you set the direction instead of just executing.
A niche with a future: A highly specialized cross-disciplinary domain with long-term growth potential – including the chance to help shape AI-supported approaches at a strategic level. Direct impact: Your work is immediately visible – to clients and management – and connects the entire FELS Group. A culture that carries you: Trust and ownership instead of micromanagement, integrity as a baseline, and a team you can rely on.
Sounds like your next challenge? We look forward to your application – let's take the FELS Group's technology to the next level together!
