• Work with product to understand requirements, then design and implement the solution;
• Build backend services in Python and frontend applications in React;
• Design and maintain REST APIs, data contracts, and integrations with external systems;

• Write tests, follow accessibility standards, and keep the UI maintainable;
• Investigate and fix bugs in production and in development;
• Add observability with OpenTelemetry and Grafana;
• Work with Terraform and GitHub Actions for CI/CD;
• Contribute to architecture decisions and help raise engineering standards;
• Use AI tools heavily to speed up design, coding, and troubleshooting — always with review and sound engineering judgment.

Required Qualifications:

• Advanced English;
• Hands-on production experience with both backend and frontend technologies;
• Python (production), REST APIs, Docker, API Gateway, PostgreSQL;
• Event-driven / async processing, message queues, workflow orchestration (e.g. Temporal);

• React, JavaScript or TypeScript, HTML/CSS, responsive UI, REST integration;
• Storybook, frontend testing with Playwright, Git;
• Knowledge of Terraform and design systems;
• Ability to turn product requirements into a technical design and working software;
• Distributed systems, resilience patterns, auth (OAuth, OIDC, SSO, RBAC);
• Production troubleshooting and bug fixing, accessibility, clear communication;
• Comfortable using AI as a core part of the workflow, with the judgment to validate, correct, and own the output.

Nice to Have:

• AI/LLM integrations, enterprise SaaS, Jest/Cypress, design systems at scale, cloud frontend deploys, mentoring.

• Health and dental insurance
• Meal and food allowance
• Childcare assistance
