Audiense Team Remote Working Meeting

Data Engineer (October, 2020)

Audiense is an equal opportunity employer, and we know it's our differences that makes us great, so we want to welcome people from all backgrounds to our family. We encourage Black, Brown, LQBTQ+, Disabled, Mums and Dads to apply!

During the application process please feel free to share which pronouns you use (she/her/hers, he/him/his, they/them/theirs). And please let us know if you need any reasonable adjustments for the application or the interview.

The challenge

At Audiense we process more than one thousand million social profiles. We enrich them by applying several classification and segmentation algorithms to help customers such as Twitter, Telefónica, DHL, and Puma to define their marketing campaigns, identify influencers and discover new market niches.

Our challenge is to optimise the intake, enriching and storage of that growing data asset and to bring the insights computing to be as close as possible to real time.

For that we have a pipeline that ingests data from an enriching system mainly written in Node.js. This system consumes from many third party APIs and applies algorithms to infer new characteristics. This pipeline is able to keep updating a data lake of more than 100TB that is used to generate reports for our customers using Spark and Scala.

Most of the Data Engineering code base is a monolith written in Scala and Spark. We are decoupling it, rewriting some parts to improve the performance and design, and migrating it to microservices. This is one of the biggest challenges that we are facing currently.

We are following Domain Driven Design, SOLID and Hexagonal Architecture principles, so we are looking for people who know and have applied them.

Besides the visual challenges, we have other interesting ones: improve our end2end tests base, decouple our front-end code from the monolith, develop a robust notifications system (CQRS) that enables the decoupling of the logic from the initial app boot and API calls, add a metrics system to improve performance applying better caching strategies, migrate legacy code to Typescript applying SOLID and Hexagonal Architecture.

But our users are not only our direct customers. We have a strong partnership program that we empower via a private API. This API is still in beta but already has more than 200 customers and a lot of potential for development.

All our stack is hosted in AWS, we use mainly Docker (ECS), EC2 and Lambda to execute our source code and a wide range of services like SQS and SNS for communication via events.

How do we work?

We have remote-first style work culture, and we have been working 100% remotely for more than 7 years. Although we have offices in Córdoba, our teams (management, sales, customer service, product, marketing and engineering) are distributed across different cities: London, Málaga, Madrid, Córdoba, Vigo, Seville, Granada...

Our mindset, workflows and communication assume that we are all remote. Almost everything is documented in Github: growth plans, learning path, architecture, protocols, onboarding, playbooks, design system, UX guidelines, etc. We invest everything in our power to automate our daily routines so that we can be as autonomous as possible to allow us to work remotely efficiently.

You will join a cohesive team (more than 4 years on average together) in a very collaborative environment in which you will feel cared for from the start of your onboarding.

Each team applies different agile methodologies but all follow some basic principles. We prioritize the features that bring more value to our customers and, instead of setting deadlines, we deliver small increments so that we always have a functional and deliverable version of the feature. We try to keep the number of tasks in parallel to the minimum possible. We have a few meetings scheduled but we will not miss the daily meetings, biweekly sprint planning and reviews. We have regular 1:1s with the manager and the CTO, and we do not hesitate to jump on to a hangout if a Slack or mail thread is getting longer.

We believe in extreme programming as a development technique so most of the time we do pair programming (yes, remotely) and TDD is our main tool for writing robust and testable code. Pair programming always helps us trust our code allowing for constant iterations. Once per sprint we spend time on joint code review to detect possible glitches to prioritize. We do continuous integration and we are in the process of extinguishing the branches to do trunk base development, there is a challenge here too.

The code we write today tries to respect the principles of SOLID, clean code and we apply hexagonal architecture and domain driven design when complexity requires it. Of course, we are not going to lie to you, during 7 years we have also done a lot of bad code and antipatterns; consider it an opportunity to see real examples of what not to do and to practise refactoring techniques.

We have a culture of continuous learning and we encourage this to happen during working hours. As a team we have made a pact of following a learning path, so by joining Audiense, you are committing to it too. If you have followed a similar path, we are eager to get to know you and learn from your experiences, if you haven’t, we are looking forward to supporting you with resources, time and mentoring so that we are aligned.

We are moving from a culture of silos towards a more t-shaped mentality. We are not looking for full-stack developers but for someone that no matter what his/her vocation is, to be versatile enough to assume the tasks that provide most value to our customers instead of the ones that better fit their skills.

You can learn more about our culture on our engineering blog and our Instagram account.

What are we looking for?

We would like you to have experience applying domain driven design, hexagonal architecture and that you understand the challenge of decoupling a monolith. We are currently implementing some of these services through a staggered approach, so any experience you have implementing event architecture is more than welcome.

We are looking for someone with experience in Scala and Spark, or at least Java with an interest in Scala, but not necessarily experience with Functional Programming since we write our code using an OO approach. Also have experience with ETLs, Data Pipelines and being comfortable with Terraform would definitely be a plus

We hope you are aligned with our core learning path (extreme programming, TDD, DDD, clean code, clean architecture, etc.) and we value all the previous experience in that sense.

We believe in pair programming and despite being remote we spend a great part of the day pairing, so we hope you feel comfortable with this practice.

Our stack is wide: Scala, Spark, Node.js (ES6 and Typescript), Python, React, MongoDB, MySQL, RabbitMQ, Redis, AWS (SNS, SQS, API Gateway, Cognito, Lambda, Redshift, Aurora, DynamoDB). However, mastering them all is not a requirement. We are more interested in the principles behind them. That said, for imminent projects, experience with Scala, Spark MySQL and some experience with ETL and Data Pipelines will help you to start producing sooner. We are looking for someone with a t-shaped mentality.

We invest our time and support in helping each other towards continuous learning, so it is very important that you want to learn and continue practising the skills necessary to run our profession. Practise, practise, practise!

Working remotely has many advantages but also requires an extra effort of communication and responsibility, so we understand that the following skills are essential: self-management, fluid communication, respect, and inclusiveness.

What we offer?

  • 40K€-60K€ salary.
  • Monthly subvention for co-workings.
  • Learning days. You can learn during working hours.
  • Training budget that includes unlimited access to SafariBooks and Coursera catalogues.
  • 100% remote and flexible schedule.

Recruitment Process

  • Send an email to jobdev@audiense.com introducing yourself and telling us why you fit the profile we are looking for. Your CV will also be useful but it is not the most important.
  • If you pass the initial application filtering, or we contact you directly, your first interview will be with our CTO (Alfredo Artiles).
  • You’ll have a second interview with some members of our team. This is a good opportunity to ask questions directly to your future teammates.
  • Then we would look for a way to validate your skills and experiences. The best way to accomplish this is by pair programming with our team in real tasks. The more time we pair, the more we both could validate if we like each other and especially if you like our way of working, the challenge and the team. Of course we would pay for your time. If this approach doesn’t work for you, we would try to adapt to you and offer other alternatives.
  • If we finally convince you to join our team, this will be the ideal onboarding:
    • Over the first few days you will be assigned a mentor who will help you set up your computer as needed and mentor you for the following months. He will explain all the workflows that we have become familiar with and hope you will too.
    • From day 1 you will become a part of the usual development flow: solving team issues and deploying code to production several times a day.
  • As our development flow is adapted to pair programming your contribution will be very progressive, and you will always have someone to revert to with any questions you may have.
