From our employees to our dealers, partners, and borrowers, we’ve built a company and a culture around a resolute belief in the promise and power of diversity.

Requirements

• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field (or equivalent experience)
• 5+ years of production backend software development experience, with proficient Python expertise
• Self-driven, adaptable, and creative problem-solver who thrives in a dynamic, fast-changing environment — able to independently tackle complex technical challenges and production issues while collaborating seamlessly within a team
• Proven track record designing scalable microservices and complex event-driven architectures using Kafka and RabbitMQ or Temporal
• Familiarity with agentic development workflows and AI coding tools (Claude Code, Cursor, or similar), and an interest in applying them to real engineering work
• Deep technical fluency with relational databases (PostgreSQL, AWS RDS), cloud infrastructure (AWS), container management (ECS/K8s), and Infrastructure as Code (IaC)

Responsibilities

• Drive the architecture and implementation of Lendbuzz's core platform to ensure high scalability and system reliability as the company grows
• Build and maintain Python backend services behind RESTful APIs and event-driven (Kafka) workflows
• Modernize legacy architecture: migrate our core platform to containerized AWS services and split out domain microservices, rolling them out safely with canary releases
• Improve CI/CD and developer experience: faster test runs, better deploy workflows, and smoother releases
• Strengthen reliability through monitoring, health checks, autoscaling, and well-run scheduled jobs and data pipelines
• Work with product and platform teams to unblock delivery and make shared systems easier to build on
