You'll also be responsible for improving and strengthening the foundation of our system, improving our team's developer experience, addressing our organizational security needs, and participating in collaborative decision-making about our architecture.

This role can be based anywhere in Europe or LATAM. Most of the team is in CET time zone. We are unable to hire in the USA at present.

Being a distributed team, we try to work asynchronously, with only a few team meetings during the week (refinement, planning, retrospective, etc). We mainly use Jira and Slack to communicate, and our tech stack is Node (mostly TypeScript), DynamoDB, MongoDB, React and AWS.

Within Three Months, You'll

  • Work with Node, Elasticsearch, Terraform, Redis, and AWS;

  • We take pride in the quality of our work, so we're looking for engineers with experience maintaining and supporting the systems they've built.
  • We're a distributed team working in multiple time zones, so excellent documentation and communication skills are paramount!

  • Familiarity with secondary tools in our tech stack, like Elasticsearch or Redis;
