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.
