Job Description

About Populate

We are a small design and tech consultancy building digital products. We do projects around digital strategy, UX, (open) data, visualization… We work together with organizations to define their digital presence and tell their stories with great UX, data visualization and fine code.

We are also building our own product: Gobierto, an open source open government platform to enable public administrations to launch engaging, beautiful and data-centric transparency, participation and accountability initiatives to better connect with their constituents.

We value

  • open: source, data, knowledge
  • balance: design your work schedule around your life, not the other way round
  • communication: remote-first approach. Good & orderly written communication > meetings > real time interruptions
  • quality: pride in process and results
  • independence: responsibility for your own work, not micromanaging

How we work

In the backend team you will participate in the development of Ruby On Rails applications. We mainly spend our time working on Gobierto, and participate in other open source projects such as Decidim and Consul (also ROR). We work with other applications from time to time. We use some Vue.js, so you will be working producing APIs and doing some integration work.

We work on Github using a git workflow with CI/CD. In Gobierto we have a pretty robust test suite to assure this is possible. Our workflow has been polished throughout a few years, so have automated many things (monitoring, error tracking, server setups & updates, deployments, various checks…). You can take a look at the Gobierto repo to see how we actually work.

Depending on your skills and interests, you may participate in:

  • Data analysis work: using SQL, R, Python
  • Systems work: servers setup, management, deploys. We use Ansible, some Docker

Day to day work

  • Plan new features of Gobierto and existing applications, and contribute to new apps from scratch
  • Implement defined features, manage your sprints, do sprint reviews
  • Collaborate with other team members: provide feedback and do code reviews
  • Improve and maintain existing code of production applications

The salary

If you are looking to maximize your salary over the type of projects/life-work balance/culture, we are not the best fit for you. We are not the latest giga-funded startup with the mission to change the world of * (really, in those startups they are changing the world about anything!) so we won’t match top paying equivalent jobs in Spain.

We are building an independent, self-financed, sustainable company with the objective of being in business for many years working on projects we believe in and that we think make the world a better place, bit by bit. Projects that are respectful with people and don’t prioritize revenue over everything.

We are growing the business and aim to pay as best as we can. We look forward to growing with you: you’ll join a place that we are all defining together so it’s the best possible place to work we can imagine of: Interesting projects, intelligent people, with stimulating challenges, that provides good work-life balance and freedom to organize your schedule. You’ll contribute to delivering projects with more efficiency so we can grow faster.

Current salary for this position is between 32,000 € and 40,000 € depending on experience, with a 5-10% yearly bonus according to your performance and company results. Yearly salary revisions.

Hiring process

  • You take some time to write the application (two questions to show your motivations on the role)
  • We look at the work you have done and some code samples (bonus points if it’s on open source repos)
  • We do a short chat over the phone. Do a longer one if everything is fine
  • If we want you to join us, we’ll make a salary proposal
  • Paid project:
    • we want to test the relationship before committing full time so we (you and us) are sure it’s a good fit. Changing jobs is stressful and time consuming and we don’t want to lose anybody’s time.
    • we’ll propose a project of around 20-40 hours so you can combine it with your current job. We agree on the fee and you complete it when you can, without stress (2-3 weeks, but we are flexible and we can define an agreement based on personal circumstances)
    • alternately, you can do this project in the office
    • we pay you this project, no matter what
  • If project is OK, everything is ready ;)
