Descripción del empleo

About the role

wealthAPI enables financial multipliers to monetize trust. We provide core financial solutions for large financial education and comparison platforms, portals and other partners. Together, we drive the ongoing disruption of the wealth management market – with one goal: empower everybody to be his or her own portfolio manager.

About you

You are an experienced software engineer and at the same time passionate about investing. You love to put your experience behind a fast growing, community-driven solution. You are able to read through order statements and to interpret the data on your own. Investment related terms like "Split", "Spin-Off", or "Knockout" are nothing new for you. Optimally, you already have hands‑on development experience with banking or brokerage APIs.

When coding, solving complex problems motivates you. Combining reverse engineering with high‑quality requirements makes your engineering skills shine. High test coverage is your standard.

Responsibilities

• Develop and improve APIs to banks, brokers and crypto‑platforms.
• Investigate, interpret and reverse‑engineer banking and brokerage APIs.
• Guide and support other team members based on your financial and technical expertise.
• Work in a small team and take product assignments to completion. You will be responsible for all the phases of planning, interpretation, development and delivery.
• Actively participate in architectural design and decision‑making.
• Conduct code peer‑reviews and attend retrospectives to plan and execute improvements as a team. Support junior and mid‑level team members to achieve high code quality.
• Use modern technologies: Spring Boot, Ruby on Rails, Postgres, Google Cloud, Kubernetes, Docker, Astra‑DB, Astra‑Vector‑DB.
• Get involved in technological projects together with experienced engineers and further improve our architecture, scalability and security to fulfil the need of our ever‑growing solution.
• Demonstrate great communication, ownership, accountability and team‑play skills. You are not "just" a developer – you will always think about our product and how to improve the experience for our customers.

Requirements

• 7+ years of software development experience
• Strong background in finance or wealth management
• Development experience in Ruby on Rails
• Development experience in Java and preferably Spring Boot
• Test‑Driven Development
• Extensive unit and integration testing skills

Beneficial

• Machine learning experience or related statistical training
• Experience with a big‑data stack such as MongoDB or Cassandra

Soft Skills

• Willingness to learn about new technologies
• Use data or reliable sources of information to drive the decision making during discussion, design or implementation phases
• Have the ability to take on complex problems, learn quickly, and persist towards a good solution
• Be conscious about speed of delivery vs quality of code and find the best balance

Language Skills

• English is mandatory
• We are an English‑first company; still, your German should be good enough to interpret a bank’s accounting statements

Benefits

• 30 days of paid leave
• Virtual shares programme
• Flexible working times
• Fully remote or hybrid positions
• Urban Sports Club membership
• Modern Apple hardware

wealthAPI is an equal career opportunity no matter your gender, identity, race or religion.

We value transparency, close collaboration, and a slight amount of chaos in our work because it makes us faster and more creative.
