This is an exciting opportunity to influence our technical roadmap while working with a modern stack including Python 3.11+, PostgreSQL, and AWS. If you are passionate about elegant code, system performance, and solving complex architectural challenges, we would love to have you on our team.

Key highlights

Design and implement high-performance backend microservices using Python, FastAPI, or Django to support our core product features.
Architect and maintain scalable data processing pipelines to handle complex transformations and large-scale data ingestion tasks.
Optimize database performance by writing complex SQL queries and designing efficient schemas within PostgreSQL or similar relational systems.
Develop and document secure RESTful APIs to ensure seamless communication between frontend client applications and backend infrastructure.

What is a Python Developer?

A Python Developer is a software engineer specialized in designing, implementing, and maintaining robust backend applications, data processing pipelines, and automation tools using the Python ecosystem. By leveraging frameworks like Django, FastAPI, or Flask, a Python Developer architects high-performance systems that handle complex business logic and high-volume data streams. Their deep knowledge of Python-based libraries such as Pandas, NumPy, and SQLAlchemy is essential for creating scalable, maintainable, and secure digital infrastructure that supports critical organizational objectives.

What does a Python Developer do?

On a daily basis, a Python Developer writes efficient, clean, and testable code, designs RESTful or GraphQL APIs, and integrates external services via secure API endpoints. They perform deep-dive debugging into production environments using tools like Sentry or PDB, optimize database queries in PostgreSQL or MongoDB, and manage containerized deployments using Docker and Kubernetes. Beyond individual coding tasks, they frequently participate in code reviews, contribute to architectural strategy meetings, and refine CI/CD pipelines in GitLab or GitHub Actions to accelerate the release cycle.
