Senior Software Development Engineer

BusPatrol is transforming student transportation safety through cutting-edge technology and real-time automated enforcement. They are seeking a Senior Software Development Engineer to lead modernization efforts and re-architect their platform for scale, performance, and innovation.

Responsibilities:

• Apply AI-driven development practices (e.g., Claude Code) and spec-driven workflows (e.g., OpenSpec) to accelerate delivery while maintaining quality through clear requirements, automated tests, and strong review discipline
• Lead engineering efforts to decompose our monolithic applications into scalable, modular microservices
• Design, develop, and maintain clean, efficient, and well-tested code in both backend (Python, Ruby) and frontend (React/Angular) stacks
• Build and evolve secure, high-performance APIs supporting real-time data pipelines and customer-facing applications
• Partner with cross-functional teams including Product, QA, DevOps, and Data Engineering to build end-to-end solutions that meet business goals
• Contribute to architectural decisions that improve performance, observability, security, maintainability and scalability/reusability
• Champion engineering best practices including CI/CD, TDD, pair programming, and code reviews
• Take ownership of projects from ideation through deployment, with a bias for execution and iterative improvement
• Be a proactive voice in platform strategy, bringing innovative ideas and continuous learning to the team
• Contribute to our cloud-native infrastructure using AWS serverless technologies (e.g., Lambda, SQS, DynamoDB, S3)
