Opis stanowiska

We are looking for a Senior Full Stack Engineer with strong experience building modern React applications and scalable Python backend systems on AWS. This role involves building responsive, user-focused frontend experiences with React and TypeScript, while also building backend APIs, async services, and AI-powered integrations in a cloud-native environment.

Your responsibilities:

Frontend

  • Build and ship React features for student-facing learning flows and teacher dashboards.

  • Write clean, maintainable TypeScript and JavaScript across the frontend codebase.

  • Manage application state using Redux, Zustand, or Context API.

  • Ensure UI components are accessible, responsive, and performant.

  • Collaborate closely with design to translate requirements into polished, usable interfaces.

  • Write unit and integration tests for frontend components and flows.

Backend

  • Design and maintain Python backend APIs; 

  • Implement asynchronous processing and queue-based communication between services (SQS, Celery).

  • Design data access patterns across both NoSQL (DynamoDB) and relational (PostgreSQL) storage.

  • Integrate backend services with internal systems, external APIs, and AI/LLM-based components.

  • Build and maintain operational tooling for day-to-day platform tasks.

  • Contribute to observability - logging, metrics, tracing, and alerting across distributed services.

  • Set up and improve CI/CD pipelines and deployment automation.

  • Contribute to architecture decisions and raise the bar through code reviews and documentation.

We are looking for you, if you have:

Frontend

  • Strong React experience - component architecture, hooks, and performance optimization.

  • Proficient in TypeScript and JavaScript; comfortable working in mixed codebases.

  • Experience with state management - Redux, Zustand, or Context API.

  • Solid understanding of web fundamentals: HTML, CSS, browser APIs, accessibility.

  • Experience writing frontend tests (Jest, React Testing Library, or equivalent).

Backend

  • 5+ years of full stack experience with significant backend exposure.

  • Strong Python - FastAPI, Django, or Flask in production; familiarity with Pydantic and SQL Alchemy.

  • Hands-on with AWS: Lambda, API Gateway, DynamoDB, S3, CloudWatch.

  • Experience with async processing and queue-based architectures (SQS, Celery, or equivalent).

  • Good knowledge of PostgreSQL and relational data modelling alongside NoSQL.

  • Experience with pytest and automated testing practices.

General

  • Ability to apply clean code practices and common design patterns.

  • Daily user of AI coding tools (Cursor, Claude Code, Copilot, etc.).

  • Experience working in agile teams with evolving requirements.

  • Fluent English, spoken and written

NICE TO HAVE

  • Experience with speech APIs, NLP, or LLM integrations.

  • Experience with AWS, Terraform, Docker, CI/CD like Github Actions.

  • Familiarity with AI agentic frameworks (LangChain, LangGraph, or equivalent).

  • Background in EdTech or consumer-facing applications

We offer:

  • Participation in interesting and demanding projects.

  • Flexible working hours.

  • A great, non-corporate atmosphere.

  • Possibility to work remote or hybrid (2 days per week from the office).

  • Opportunities for development and promotion.

  • Attractive package of benefits.

We reserve the right to contact the selected candidates.
