Activities
Who We're Looking For
You're equally at home crafting robust APIs and building polished front‑end features. Python micro‑services, TypeScript components, Docker containers, and CI/CD pipelines are your daily toolkit — and you love seeing the whole puzzle fit together in production. If you thrive in a collaborative, fast‑moving environment where your ideas are used by large enterprises, this role is for you.

Role Overview

As a Full‑Stack Developer you'll own end‑to‑end feature delivery: from database schema to REST endpoint to responsive UI and all the automated tests in between. You'll partner closely with product, design, and data‑science teams to shape the roadmap and continuously raise the technical bar of our analytics platform.

Key Responsibilities

• Feature Delivery
• Design and implement new product features across the stack (FastAPI, MongoDB, React/Vue/TypeScript).
• Develop scalable background jobs (Celery, asyncio) for data processing and enrichment.
• Code Quality & Testing
• Use test‑driven development with pytest, React/Vue Testing Library, and Playwright.
• Conduct peer code reviews and uphold internal coding standards.
• Performance & Reliability
• Profile services, optimize queries, and introduce caching / async patterns.
• Instrument robust logging, monitoring, and alerting (Grafana, Prometheus, Sentry).
• DevOps & Delivery
• Define Docker images, helm charts, and GitHub/GitLab Actions pipelines for build & deploy.
• Contribute to our Kubernetes‑based runtime and infrastructure‑as‑code.
• Collaboration & Leadership
• Participate in sprint planning, architecture sessions, and customer demos.
• Mentor junior engineers and working students; share knowledge through pair programming and internal talks.

Team

• We are a young and dynamic team, working collaboratively to pursue our mission.
• We use the latest technologies and tools to collaborate efficiently and deliver high-impact solutions for our customers.
• Our 7-person team consists of the founding members and our dedicated working students. Freedom to organize your own work and shape your area of responsibility is a key part of our company culture.
• We place great value on trust, honesty, and working together as equals.
