Jobbeschreibung

At kiresult, you'll work on an innovative SaaS product that turns complex procurement data into clear, actionable insights for leading enterprises. As a full-stack developer, you’ll own features end-to-end — from backend logic to polished UI — and see your work deliver real impact in production. You'll join a fast-moving, collaborative team where your ideas directly shape the future of our platform.

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

1. 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.

2. Code Quality & Testing

Use test‑driven development with pytest, React / Vue Testing Library, and Playwright.

Conduct peer code reviews and uphold internal coding standards.

3. Performance & Reliability

Profile services, optimize queries, and introduce caching / async patterns.

Instrument robust logging, monitoring, and alerting (Grafana, Prometheus, Sentry).

4. 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.

5. 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.

Comfortable with Docker, container orchestration basics, and Git‑based workflows.

Proven track record writing unit / integration tests and operating services in production.

Excellent English communication skills (German a plus).
