Senior Software Development Engineer

Senior Software Development Engineer Overview At BusPatrol, we’re transforming student transportation safety through cutting-edge technology and real-time automated enforcement. We're seeking a Full Stack Developer to be at the forefront of our engineering evolution—from a legacy monolith to a modern, microservices-based Automated Safety Platform. As a Full Stack Developer, you won’t just write code—you’ll be a key driver in re-architecting our platform for scale, performance, and future innovation. You'll collaborate across geographies with engineers, product managers, and designers to deliver resilient, secure, and customer-focused experiences. This is more than a development role—it’s an opportunity to lead modernization efforts, influence technical direction, and bring meaningful safety improvements to millions of children and families. Key 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). Preferred Qualifications Experience with AI-assisted / AI-driven development using tools such as Claude Code , and spec-first delivery with frameworks such as OpenSpec (writing clear specifications, generating/maintaining tests, and iterating safely with human review). 5+ years of software development experience; strong foundation in backend systems using Python (must-have) and Ruby (nice to have). Experience with modern front-end frameworks such as React , Angular , or VueJS . 3+ years of experience with backend web frameworks (e.g., Django, Flask, Rails). Hands-on experience with AWS services : Lambda, S3, SQS, API Gateway, CloudWatch. Comfortable working in an agile, test-driven development environment with modern DevOps tooling. Practical knowledge of RESTful APIs, SQL/NoSQL databases (MySQL, Postgres, DynamoDB), GraphQL. Design and implement event-driven services using technologies like AWS EventBridge, SNS/SQS, etc to enable decoupled, scalable communication between microservices Experience designing and consuming gRPC APIs in production environments a plus Proficient in containerization (Docker) and CI/CD pipelines. Familiarity with testing and linting tools (pytest, rspec, jest, Flake8, RuboCop). Excellent communicator with a strong collaborative mindset and a passion for mentoring and peer reviews. BS/MS in Computer Science or equivalent experience. Why Join Us Be part of a mission-driven company making roads safer for students and communities. Help architect the future of our Automated Safety Platform . Work on modern, cloud-native, and serverless technologies. Collaborate with a global, inclusive, and high-performing team. #J-18808-Ljbffr
