Job description

What would you do?

• Build features end to end: Backend (Node/TypeScript/Express) and the screen that consumes it (React/TypeScript).

• Develop and evolve the e-commerce admin business modules: coupons, campaigns, carousels, categories, tags, customers, retailers, and Dynamic Home.

• Integrate services with RTK Query with internal microservices

• Maintain the mass-update and reporting flows: file uploads, templates, S3 downloads, and cron jobs.

• Apply module- and action-level permissions, multi-tenant/multi-brand logic, and feature flags (Statsig) in every new feature.

• Write tests for every new behavior (Jest, Testing Library, MSW on the frontend; Jest and supertest on the backend), phrased as business requirements.

• Incrementally migrate legacy to new: API v1 to v2, and MVC to DDD in Wanda.

• Take part in releases and operations: GitHub Actions, semantic-release, CodeBuild/S3/CloudFront, Docker/ECS, and Terraform.

• Maintain quality and observability: ESLint, Sonar, Sentry, and internationalization in 6 languages.
  

Your experience has been shaped by

• React 18, TypeScript, and Redux Toolkit/RTK Query in a large application organized by domain modules.

• Micro-frontends with Single-SPA and SystemJS, with a dual Vite (dev) and Webpack (prod) build.

• Node.js with Express as an API Gateway over microservices, with PostgreSQL and parameterized SQL.

• Clean architecture/DDD with repository injection, and legacy code coexisting with new code.

• Authentication and authorization with JWT/JWKS, granular permissions, and multi-client, multi-language systems.

• Automated testing and TDD with Jest, Testing Library, MSW, and supertest.

• AWS (S3, CloudFront, Lambda, ECS, ECR, CodeBuild), Docker, and Terraform, with multi-region deployments.

• CI/CD and release engineering: GitHub Actions, SonarCloud, conventional commits, squash merge, and semantic-release.

• Feature flags with Statsig, Sentry (tracing and error boundaries), and complex forms with Ant Design, react-hook-form, and zod.

• Development workflows with AI agents (Claude Code): specs, automated reviewers, and PR quality metrics

• E-commerce/retail domain: catalogs, promotions, coupons, retail media campaigns, and mass operations.
  

Your SuperPowers

• Full-Stack Ownership: You can confidently build and maintain end-to-end features across the frontend and backend, with strong foundations in TypeScript, Node.js, REST APIs, and modern frontend frameworks.

• Adaptability in a Startup Environment: You thrive in fast-paced environments where priorities evolve, solutions are not always straightforward, and you need to adapt quickly while delivering meaningful results.

• Problem-Solving & Technical Resilience: You enjoy tackling complex or unfamiliar challenges, navigating existing technical debt, and finding pragmatic solutions that improve the product incrementally.

• Frontend Craftsmanship: You understand how to build reliable, maintainable user interfaces and integrate them seamlessly with backend services. Experience with React, TypeScript, and Redux is a strong plus.

• Collaborative Ownership: You work autonomously, take responsibility for your commitments, and collaborate proactively with cross-functional engineering teams to achieve shared goals.

• Continuous Improvement: You look beyond simply implementing requirements. You identify opportunities to improve existing systems, refactor when needed, and contribute ideas that make the product and the team more effective.

• Emerging Technical Leadership: You bring the technical judgment and initiative to help shape a growing team, share knowledge, and progressively take on greater technical leadership responsibilities.
  

What we bring to the table

• Full Remote Work: Work together as a team.

• Flexible hours: We trust your work and skills.

• Additional days off to vacations.

• Half day off on your birthday.

• Access to Educational Budget.

• Health insurance: Get the attention and care that you deserve. Available in some countries.
