About the role

Key responsibilities & impact

You'll implement backends and their interactions with various data stores and other APIs (including 3rd party APIs).
You'll work in an agile environment focusing on projects that are impactful on our business.
You'll support reliable databases and APIs for real-time automated decision-making.
You'll deploy your software using industry-standard tooling like Kubernetes clusters, and Lambda functions.
You'll investigate and resolve production issues by analyzing code, data, and system behavior and then propose and implement timely fixes to minimize user impact.
You'll care deeply about security in everything you do and constantly raise the baseline of how we defend our user's data against external threats and themselves.
You'll implement robust automated test suites to ensure high quality and low failure rate of delivered code.
You'll work closely with Product Managers, Senior Engineers and Architects to understand business processes, rules, and requirements, and turn them into high-quality code with automated tests, and deploy them to production.
You’ll have a lot of chances to develop your programming skills as well as learn a lot about how tech business is done in the US (if you want to).

Requirements

What you’ll need

Have at least 3 years of hands-on experience with Node.js, JavaScript, and TypeScript.
Possess a good, practical knowledge of at least one relational database system, e.g. PostgreSQL/MySQL/SQL Server.
Can engage in discussions and decisions regarding software design and architecture.
Have experience implementing the test pyramid (unit, integration, e2e tests).
Are a team player and a good communicator, with the ability to convey ideas clearly across technical and non-technical teams.
Can demonstrate responsibility, accountability, and a strong sense of ownership in delivering high-quality work.
Utilize good security practices effectively.
Show readiness to learn and expand your skill set as required by ongoing projects.
Have a good command of English (written & spoken).
Are available in the afternoons – we prioritize everyone’s personal time and work-life fit, but since we work in multinational teams, occasional evening meetings may be necessary to ensure smooth communication across time zones.
