Senior Backend Engineer - Python & Databricks

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Backend Engineer -- Python & Databricks based in Brazil.

We are seeking a hands-on Senior Backend Engineer to design, develop, and operate reliable backend services and production-grade REST APIs. In this remote role, you will work primarily with Python, FastAPI, and Microsoft Azure, contributing to scalable systems and data-driven products. You will help build and maintain a communications dispatch service that connects messaging queues, external APIs, databases, and data platforms such as Databricks. Working closely with development, data, and IT/DevOps teams, you will contribute to architecture, integrations, and deployment processes. The role offers the opportunity to take ownership of technical solutions in a collaborative, learning-oriented environment focused on clean code, reliability, and continuous improvement.

Accountabilities

• Design, develop, and evolve backend services and REST APIs using Python and FastAPI, following sound practices for architecture, security, and maintainability.

• Build and operate a communications dispatch service integrating messaging queues and external APIs, implementing idempotency, retries, rate limiting, and robust error handling.

• Integrate and orchestrate Azure services, relational databases, third-party APIs, and data processes running on platforms such as Databricks.

• Design and maintain Azure SQL persistence solutions, including data modeling, migrations, data integrity, and query optimization.

• Improve production reliability and observability through monitoring, tracing, automated testing, and failure recovery mechanisms.

• Collaborate with development, data, and IT/DevOps teams on technical decisions, integrations, CI/CD pipelines, and deployments across environments.

• Maintain clear and useful technical documentation.

Requirements:

• At least 4 years of backend development experience, including building, integrating, and operating production services.

• Strong proficiency in Python and experience developing REST APIs with FastAPI or equivalent frameworks.

• Ability to design modular, maintainable software using principles such as SOLID, separation of concerns, and automated testing best practices.

• Experience integrating APIs and distributed systems, including authentication, timeouts, error handling, retries, and resiliency patterns.

• Experience with asynchronous processing and messaging systems, including queues, dead-letter handling, and idempotency; Azure Service Bus or equivalent technologies are relevant.

• Strong SQL and relational database skills, including data modeling, querying, migrations, and ORM usage. SQL Server or Azure SQL experience is preferred.

• Experience with Docker and deploying containerized services.

• Hands-on experience with cloud services, preferably Microsoft Azure, as well as monitoring, Git version control, and CI/CD processes.

• Strong ownership, problem-solving, collaboration, and communication skills.

• Nice to have:

  • Experience with AI-assisted development tools such as Claude Code, GitHub Copilot, or Cursor, or with Spec-Driven Development practices, alongside the ability to validate generated code for quality, security, and maintainability.

  • Experience integrating and orchestrating backend data processes, particularly with Azure Databricks or similar platforms.

  • Familiarity with cloud-based container infrastructure, including Kubernetes/AKS or Azure Container Registry.

  • Knowledge of marketing technology, customer engagement, or digital experimentation platforms, including push, email, in-app messaging, or A/B testing integrations.

  Benefits:

  • Remote-first culture, with the flexibility to work from anywhere.

  • Full coverage of certifications in AWS, dbt, Google Cloud, Azure, and Databricks.

  • Birthday day off and an additional vacation week.

  • Referral bonuses for successful candidate recommendations.

  • Monthly credits through the Maslow benefits marketplace.

  • Annual team trip.

  • Salary and additional healthcare benefits are not specified in the job description.
