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 are looking for an experienced Full-Stack Engineer with strong backend expertise to join our growing Sales R&D team in Tel Aviv. This is a backend-leaning role focused on building and maintaining high-performance systems while contributing across full-stack services. As part of our team, you’ll drive the evolution of our Sales platform, take end-to-end ownership of impactful features, and contribute to an AI-first engineering culture that embraces automation, intelligent tooling, and continuous improvement. You will play a key role in improving product quality, engineering productivity, and system reliability as we support rapid business growth.

Design and deliver end-to-end features across backend services and frontend applications, with strong emphasis on backend architecture, data integrity, and system reliability.

Develop and maintain SPA web applications for admin and product platforms using React + TypeScript and Next.js, including contributing to the modernization of legacy Ruby components.

Develop and maintain backend services across Python (FastAPI) and Node.js (NestJS) microservices, ensuring strong performance, robust data management, and ongoing modernization efforts.

Design, implement, and maintain reliable REST APIs with clear contracts, validation, and consistent error handling.

Work with complex relational data models, continuously improving query performance and data reliability.

Lead investigations and root-cause analysis for performance, optimization, and production-related issues, driving long-term improvements.

Collaborate closely with frontend, backend, QA, and product teams in a multi-repo environment, including active code reviews and cross-site collaboration with our Boston engineering team.

Take ownership of code quality and production stability by writing automated tests (e.g., pytest, Jest) and driving issues from investigation through resolution and prevention.

B.Sc. in Computer Science or Software Engineering from a top-tier academic institution (Technion, TAU, BGU, HUJI, or the Open University)

3+ years of professional software engineering experience building and maintaining production web application systems.

Strong backend experience with Python or TypeScript, working within service-oriented architectures.

Experience developing frontend web applications using TypeScript and modern frameworks such as React.

Solid production experience with relational databases, including schema design, query optimization, and performance tuning.

Experience working with AWS and cloud-based infrastructure, and improving developer workflows in multi-repo environments.

Experience designing and maintaining REST APIs used by web applications.

Strong debugging skills and experience troubleshooting performance and reliability issues in production systems.

Proven experience leading the full dev lifecycle: from driving technical design and scaling product requirements, to hands-on execution with high standards for code reviews, documentation, and incremental delivery.

Strong communication skills and an ownership mindset.

Hands-on experience with FastAPI and/or NestJS.

Strong experience with PostgreSQL, including advanced schema design, indexing strategies, and performance optimization.

Experience writing automated tests (unit + integration) and end-to-end testing using tools such as Playwright.

Experience working with observability and monitoring tools such as Coralogix and Sentry.

Experience with performance testing tools (e.g., JMeter, k6) and monitoring stacks (e.g., Prometheus, InfluxDB, Grafana).

Experience working in a monorepo environment with shared code and coordinated cross-project changes.

Experience with Redis, RabbitMQ, or Kafka.
