Job Responsibilities:
- Take ownership of complex, cross-functional features within the application.
- Architect and implement scalable and performant new features, with a focus on reliability and maintainability.
- Write and maintain complex SQL queries.
- Collaborate closely with the product team to transform feature requests into actionable implementations.
- Lead code reviews to ensure code quality, setting a high standard for engineering excellence.
- Mentor and support junior engineers, sharing expertise to elevate the team.
- Optimize our database systems through performance analysis and scalability planning.
Required Skills & Experience:
- 5+ years of experience solving complex technical problems.
- A history of developing large web applications and REST APIs.
- Advanced proficiency in TypeScript
- Extensive experience with data modeling and optimizing complex database queries against database systems such as PostgreSQL, Cassandra, and/or Elasticsearch.
- Proven expertise in system architecture and performance optimization for large-scale systems.
- Strong familiarity with writing unit and integration tests, as well as knowledge of DevOps practices, including CI/CD, Docker, and Kubernetes.
