- Use best-in-class software development practices (unit tests, integration tests, performance tests, monitoring, detailed functional specification and test plans) to ensure RapidSOS' products remain highly reliable and fault tolerant
- Identify opportunities to assess and enhance current applications, including refactoring code and upgrading technologies used
- Collaborate in an agile environment with stakeholders across Engineering, Design, GTM, and Product to develop solutions for RapidSOS products
- Leverage modern AI development tools (Claude Code, Cursor or similar) to accelerate delivery and improve code quality
- Actively participate in code reviews and standups, sharing knowledge, championing best practices, and contributing to the continuous improvement of team processes
- Own meaningful parts of our platform, have an impact, grow with the company
What we're looking for in our ideal candidate: - 5+ years of professional backend or full-stack engineering experience with deep expertise in Python and proficiency with React & TypeScript
- Experience integrating with RESTful APIs and delivering comprehensive end-to-end solutions in an AWS environment
- Experience working with relational and non-relational databases and message bus systems (RabbitMQ, Kafka, AWS SQS / SNS)
- Ideally has experience building AI-driven features or using AI tools to enhance acceleration of development, and is proactive about leveraging emerging technologies
- Strong communication and interpersonal skills; is a team player with a positive attitude
- Highly self-motivated; ability to adapt and learn quickly in a fast-paced environment with a strong sense of ownership
- Strong proficiency in coding best practices - ability to write clean, maintainable, and testable code
- Customer-centric mindset; cares deeply about delivering solutions that enable and delight customers while meeting product goals
- Demonstrated expertise in problem solving - from troubleshooting issues to debugging a large codebase
- Ability and willingness to collaborate in-person a few times per quarter, or as needed
Nice-to-have experience (but not required!):- Experience with telephony / VoIP / SIP

What we offer: - The chance to work with a passionate team on solving one of the largest challenges globally
