Job Description

Lana is a new project born out of Cabify's and Maxi Mobility's New Business department. The aim is to create an alternative banking platform optimised to empower "gig economy" workers to get paid more quickly, reliably, for saving and making payments. Lana is a small, dedicated, and highly skilled team focussed on building an awesome product with the potential to grow into a company that changes the lives of millions of people in Latin America who don't currently have access to electronic banking.

The New Business department and Lana are very closely joined with Cabify and Easy Taxi teams with the aim of adding value and investigating business areas that are directly or indirectly related to the core products.

If we’re going to turn our vision into a reality, we’re going to need plenty more bright, ambitious people to join us!

About the position:

As a senior engineer in the Lana Core Team, you will be working to solve complex problems in the services that empower the rest of the company to run. You'll be actively working with the CTO and other areas of the business so you can determine the direction development should move in.

Lana strives for a modular working environment where each module determines its own development pipeline, according to the general direction of the company and requirements of the customers.

Our current backend tech stack for this project consists of:

• Go
• Docker + Kubernetes
• CouchDB
• CockroachDB

We are looking for someone with previous experience working with Go (desirable), however if not we are still happy to consider your application. We believe that even if you have worked in Java or C# all your life you can still pick up Go pretty quickly. For us it is more important to have someone who is adaptable and can pick up languages quickly.

Security is a major concern for this project, so decisions on how best to isolate, restrict, and monitor access to services and solutions will be a big challenge.

What we’re looking for:

We’re searching for engineers with a solid understanding of how to deal with building secure, reliable, and scaleable solutions. Your objective will be to build upon the existing core services to ensure that the other areas of the company can also develop solutions in their problem domains.

This is a hands-on role in a new project within the group, so it's a great opportunity to make your mark from the very beginning. Your decisions will affect how the company moves in the future.

We'll be looking for most of the following in your profile:

• Strong educational background, e.g Degree in Computer Science, Physics, Engineering, Mathematics, or equivalent
• Ability to communicate with the team in English (written and spoken)
• Unix/Linux systems knowledge
• A background in security and a deep understanding of the potential risks.
• Fintech, Payments, and PCI experience very highly valued.
• Real-time distributed systems deployment.
• A preference for simple system architectures and micro-services, including experience in technologies like Docker.
• Advanced networking knowledge.
• Ability to work autonomously in an unstructured environment.
• Passion for writing simple, clean and efficient code and/or solutions.
• Comfortable with complex git/github workflows (submodules, branches, forks, pull requests, merging, rebasing)

The good stuff:

As part of the Maxi Mobility group, which includes Cabify, we’re a company full of happy, motivated people and we never want that to change. Here are some more reasons why it rocks to be part of our family.

• Flexible work environment & hours
• Regular fun team events
• Cabify staff discount
• Personal development programmes
• All the gear you need - just bring yourself.
