A little bit about Flanks

Flanks is a Barcelona-based fintech company focused on wealth management services. Its main product is a SaaS solution that helps financial advisors, family offices and other institutions to have a holistic view of their clients’ financial assets while using the latest scraping technology. We’re currently building the benchmark in the OpenWealth industry, and so far we managed to have compatibility with over 250 national and international entities.

Thanks to our clients, we continue to grow at a fast pace. We have already more than 300,000 aggregated portfolios spread across nearly 250 entities and have positioned our business at break-even in less than a year. In August 2021, Flanks raised €2.3 million in an investment round led by JME Ventures and SeedRocket 4Founders Capital. And a significant €7.5 million in August 2023, demonstrating confidence in our vision and capabilities.

We are pioneers in our market in Spain, which will certainly grow a lot in the next few months and years. However, we are going to take a league leap in terms of the volumetry of the system, as our key focus now is to accelerate our market expansion in Europe and LatAm. And we would like to count on you to also grow (personally and professionally) with us.

Flanks’s values are:

  • People first: To us, the most important thing is for “Flankers” to feel at ease, for them to get involved in a project and be feel part of the team.
  • Keep growing: Our team believes that people growing in lockstep with the company is essential, both personally and professionally.
  • Think twice, act once: We like to think about all the possible consequences before taking any decision that could affect the team or our clients.

If you’re looking to grow professionally in a very fast-growing company with an exciting start-up culture, this is your opportunity!

About the role

You will be a Backend Developer in our company. You'll be working as a full member of the Drivers team, participating in the process of data extraction from various custodian entities. You will be working with Python as a basis and custom techniques and methodologies in order to make data extraction and processing at large scale. You will cooperate with technical and financial people in order to understand in detail what you’re processing.


Examples of tasks you can expect to work on are:

  • Understand and automate the login process of financial institutions websites with multi factor authentication mechanisms
  • Reverse engineering of online banking websites
  • All of the steps of an ETL data pipeline
  • Data extraction from websites content, csv and pdf documents

Our tech stack

  • Python as code base
  • Browser emulation tools
  • Pandas for document data parsing
  • Jenkins as CI/CD
  • MongoDB as data storage tool

Things we'd love to see on you

  • You are a nice person: Assholes and bigotry won’t be tolerated.
  • You live in Barcelona City and/or close enough to work at the office twice/three times a week. Living in Spain is a mandatory requirement, and a non-negotiable requirement.
  • Likewise, we can’t offer a relocation package and/or working visa.
  • You have working English and Spanish proficiency.
  • You have some experience in similar roles. We're looking for someone with some lessons already learned.
  • Working experience with data pipelines and scrapping.
  • You are familiar with MongoDB.
  • Meaningful experience with Javascript will be a huge plus.
  • We will be helping you to grow, so don't worry if you don't check all the boxes!

What can we offer

We offer what we think is fair compensation (from 23K to 30K € per year for this role). We're on top of the market, but our intention is to increase compensation as the company grows. You will not be left behind. We believe this is a really nice time to join the project. This is a full-time, permanent contract.

A non-exhaustive list of perks includes:

🏠 Office between Sants Estació and Plaça Espanya, with a 280 degree view of Barcelona.

🔆 Flexible working hours

🎊 Paid time off on your birthday

🍒 Fresh fruit every week, all-you-can-drink tea and coffee

The hiring process

This is how the usual hiring process looks like:

  1. You send us your resume, cover letter, etc.
  2. A chat with our CTO Sergi Lao, where we’ll dive deeper into your background, your possible fit, and where you’ll have the opportunity to ask any sort of questions.
  3. We will send you a technical test so we can see how you deal with problems and how you manage Python.
  4. A meeting with our CTO and our CEO Joaquim de la Cruz.
  5. Optionally, any other meeting you or us might need to clarify any pending questions.
  6. We send you an offer.

We expect a few days to pass between each step. We aim for a process as short as one week and never longer than one month.
