Junior Back-end Engineer Santiago

Description

We are looking for a Junior Backend Engineer with a strong foundation in Python and an interest in building modern, data-intensive software systems. You may be a recent graduate with strong practical experience or have approximately 1–3 years of professional software development experience.

You should be comfortable writing Python and have some experience building APIs using FastAPI, Django, Flask, or similar frameworks. A basic understanding of RESTful APIs, databases, Git, and software development best practices is expected.

You will work alongside experienced engineers on backend services, data pipelines, APIs, and cloud-based systems that process large volumes of retail data. You will have the opportunity to develop practical experience with technologies including cloud platforms, analytics databases, data orchestration tools, and AI-enabled development workflows.

We value curiosity, ownership, a willingness to learn quickly, and the ability to solve problems collaboratively. You do not need to have experience with every technology in our stack, but you should have strong technical fundamentals and be motivated to grow into a highly capable backend engineer.

Functions

• Develop and maintain backend services using Python and FastAPI.
• Help build and improve data ingestion and processing pipelines that power analytics for global consumer brands.
• Build and maintain API services that support the Krunchbox platform.
• Work with large datasets and help improve system performance, reliability, and scalability.
• Contribute to cloud infrastructure and CI/CD workflows.
• Collaborate closely with senior engineers, product, and data teams to deliver new capabilities.
• Participate in code reviews, technical discussions, and architecture decisions.
• Write clean, well-tested, and maintainable code.
• Contribute to engineering documentation and best practices.
• Use modern AI-assisted development tools to accelerate learning, coding, debugging, and problem-solving.

Desirable

Nice-to-have skills include:

• Experience with FastAPI or another Python web framework.
• Familiarity with SQL and relational databases.
• Exposure to cloud platforms such as AWS, Azure, or GCP.
• Experience working with ETL/ELT processes or data pipelines.
• Familiarity with analytics databases such as ClickHouse, Snowflake, BigQuery, or Redshift.
• Exposure to orchestration tools such as Airflow, Dagster, or Prefect.
• Basic full-stack experience with React or TypeScript.
• Interest in AI/ML systems and infrastructure.
• Experience using AI-assisted development tools such as Claude Code.
• Personal projects, internships, open-source contributions, or university projects that demonstrate strong software engineering skills.

Benefits

• Competitive compensation package.
• Comprehensive health and benefits coverage.
• A predominantly in-person, collaborative work environment in Santiago that encourages learning, fast iteration, and real-time problem solving.
• Mentorship and the opportunity to learn from experienced engineers working on complex, real-world systems.
• Exposure to large-scale retail datasets, modern cloud architecture, data engineering, and AI-enabled product development.
• Significant opportunities for professional growth as Krunchbox scales globally.
• The opportunity to contribute directly to the future of AI-powered supplier-retailer collaboration.
