Software Engineer (Backend)

At Lendbuzz, we believe financial opportunity should be more personalized and fair. We develop innovative technologies that provide underserved and overlooked borrowers with better access to credit. 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. We value independent and critical thinking.

We're looking for a backend-focused Software Engineer to build high-quality, scalable backend systems behind our products and help shape the user experiences they power.

As part of our Boston-based Core squad, you'll take on complex, high-impact technical challenges that help our product teams move faster. You'll play a key role in making Lendbuzz's products reliable and sustainable as we scale.

Key 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

Key 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)

We believe:   Diversity is a competitive advantage. We celebrate our differences, and are better when we have a variety of experiences, viewpoints, and backgrounds.   Compassion is a strength. We care about our customers and look to build long-term relationships with them.   Simplicity is a key feature. We work hard to make our forms and processes as painless and intuitive as possible.   Honesty and transparency are non negotiable. We incorporate these traits in all of our interactions.   Financial opportunity belongs to everyone. We work every day to improve lives by extending this opportunity.   If you believe these things too then we would love to hear from you!
