Company mission
Scalable Capital's mission is to provide people with professional, intelligent, and at the same time cost-effective solutions for wealth creation, trading and investing.
Role
Who you are
- Strong experience building backend services with Kotlin or Java and Spring Boot
- A solid understanding of Domain-Driven Design and the ability to translate complex business processes into clear software models
- Experience designing and operating distributed, event-driven systems and APIs
- Familiarity with cloud-native development on AWS, especially containerised and serverless workloads
- Confidence with automated testing, CI/CD, infrastructure as code and production observability
- A quality and security mindset, with attention to reliability, maintainability and operational ownership
- Clear communication skills and a collaborative, pragmatic approach to solving problems
- An interest in complex financial workflows or the curiosity to learn them quickly. Exposure to SEPA payments or payment processing would be a plus
- A university degree in a relevant field of study (e.g. computer science, engineering, sciences, ...) or a comparable qualification
What the job involves
- Build and evolve business-critical payment services using Kotlin, Java and Spring Boot, enabling customers to move money reliably through SEPA while supporting the wider banking platform
- Develop services across the payment lifecycle, including initiation, validation, execution, status handling, returns, exception management and reconciliation
- Design clear domain models, APIs and event-driven workflows connecting customer-facing products with internal systems and external banking partners
- Write clean, secure, well-tested and maintainable code, with particular attention to correctness, resilience and traceability when moving money
- Develop and operate cloud-native applications on AWS, including containerised services on ECS and event-driven workloads on Lambda
- Shape reliable delivery and operations with infrastructure as code, CI/CD pipelines, observability and monitoring
- Work in autonomous, cross-functional teams using agile practices, Domain-Driven Design, code reviews, automated testing and continuous delivery
- Take ownership from idea to production, delivering measurable value while improving quality, automation, reliability and developer experience
Our take
Interest around investing in digital assets is increasing steadily due to innovations in fintech smartphone applications and the popularity of blockchain finance such as cryptocurrency. While stocks and cryptocurrency have a lot to do with this increase in popularity, it has also led to new investors learning about ETFs and index funds, meaning more people are looking for easier ways to invest.
Scalable Capital provides a free smartphone application for the investing and trading of stocks, cryptocurrencies, commission-free ETFs, and index funds, with subscription fees providing commission-free stock trading. The application also features a machine learning-driven robotrading service called Smart Predict to aid in improving users' limit and stop orders.
Whilst several other European investment platforms focus on commission-free trading, Scalable Capital has taken a fresh perspective by focusing on providing commission-free ETF investment. By doing this, the company encourages smart long-term ETF investments over riskier day-trading, tapping into a more mature market than applications focused on stocks. With substantial growth reported in 2025, Scalable Capital is carving out its market share.
