Senior Frontend Engineer

Redefining the wealth management industry to make it simpler, seamless, and accessible to more people.

A little bit about Flanks

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.

Founded in 2019 and based in Barcelona, we've brought together a team of passionate wealth management and tech pros, all with a shared goal : to change how wealth management is done. Backed by €9.8 million in investment, we're growing fast, and we're not stopping anytime soon!

What we stand for People First – our team comes first. We want every Flanker to feel at home, engaged, and part of something bigger.

Keep Growing – as the company grows, so should you. We're all about personal and professional development here.

Think Twice, Act Once – we believe in thoughtful decisions, considering the impact on both our team and our clients before taking action.

If you're looking for a place where you can grow and make an impact at a fast‐paced, exciting fintech startup, this might just be the place for you!

Tech Team We power the ingestion, processing, and delivery of data for our customers. As we scale, new challenges arise—here's where you come in :

Build seamless user interfaces for secure credential storage (UI / UX is key!).

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.

About the role This is a general role (80% frontend- 20% backend). This does not mean we expect you to know absolutely everything. You will have your areas of expertise and things you'll like more than others. However, 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. You will still be an individual contributor, but you'll also need planning and communication skills way beyond just "doing your work" : You will have agency and accountability.

Not only that, but you will have a voice in the way we shape the future of technology at Flanks.

Our current tech stack Python or JS / Typescript on our back-end, using async frameworks and tooling for most parts.

Vue and Nuxt in our front-ends.

Running on GKE

Powered by MongoDB, PostgreSQL and Elasticsearch

Also, Github, Github actions, Redis, RabbitMQ and other usual suspects.

Things we'd love to see on you You are a nice person : We don't tolerate bigotry or toxic behavior—just good vibes.

At least 7 years on an Engineer Software role.

Autonomous coder : You don't need your work double‐checked—you're on top of it.

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.

On the other hand, you know how to read and understand job offers. You can triage what's important and what's not.

Focused : You know how to read between the lines and prioritize what matters most.

You can work with both legacy and greenfield code

You take ownership of problems.

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

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.

You don't have to check every box, but the more you fit this, the more likely we'll be excited to hear from you!

What we offer We offer what we think is fair compensation. We're not on the very top of the market, but our intention is to increase compensation as you grow with the company. You will not be left behind. We believe this is a really nice time to join the project as we'll experience some serious growth and changes during this year.
