Job Description:

Flanks is shaking up the wealth management industry by making it simpler and way more efficient for financial institutions. Our SaaS platform is designed to help banks, family offices, and wealth managers get a full picture of their clients' financial assets—all in one place. This is a general role (80% frontend- 20% backend). You will be exposed (and sometimes deeply working) on all layers of the stack: from the front-end to our APIs and databases. As a senior, you will help and support other members of the team. You are expected to take a leading role in new initiatives and to need a minimal amount of supervision and support.

Job Responsibility:

  • Build seamless user interfaces for secure credential storage
  • Handle sensitive financial data with performance, compliance, and traceability in mind
  • Scale our ingestion system to fetch more data, faster
  • Mentor and grow the team, ensuring alignment and consistency as we expand
  • Help and support other members of the team
  • Take a leading role in new initiatives
  • Have a voice in the way we shape the future of technology at Flanks

Requirements:

  • At least 7 years on an Engineer Software role
  • Autonomous coder
  • You know your way around collaborating with others using standard tooling (git, github PR's, etc)
  • You are a good communicator who knows how to express problems, solutions and trade-offs
  • You know how to read and understand job offers
  • Focused
  • You can work with both legacy and greenfield code
  • You take ownership of problems
  • You live in Spain and are close enough to Barcelona to commute to the office once a month by your own means
  • Living in Spain is a mandatory and non-negotiable requirement
  • You’re fluent in English and Spanish
  • Experience matters: This is not an entry-level role
  • Tech savvy: Familiar with our tech stack—or similar ones

Nice to have:

Wealth knowledge: A little expertise in investments, currencies, crypto, or wealth management is a plus

What we offer:
  • A cool office between Sants Estació and Plaça Espanya with stunning views of Barcelona
  • Flexible working hours and hybrid work options
  • Paid day off on your birthday
  • Weekly fresh fruit, coffee, and tea on tap
  • Friday happy hours after our all-hands meetings
  • Team-building events
  • Health insurance and flexible compensation with Alan
  • A digital canteen, thanks to Nora Real Food, subsidised at 50%
  • A yearly training budget
