If you are passionate about building robust systems and want to have a major impact on the product's growth, this is the role for you.
About The Role:
- Build, optimize, and maintain scalable backend services and APIs using Go (Golang) and Node.js.
- Collaborate with frontend engineers to build full-stack applications that are highly performant and user-friendly.
- Design and implement robust systems for managing data at scale.
- Write clean, efficient, and testable code, and work to maintain high code quality standards.
- Participate in architectural decision-making and mentor junior engineers.
- Troubleshoot and resolve complex technical issues in production.
About You:
- 5+ years of professional backend development experience.
- Expertise in Go (Golang) and Node.js.
- Experience with cloud platforms (AWS, GCP, Azure) and serverless architecture.
- Solid understanding of microservices and distributed systems.
- Familiarity with modern containerization tools like Docker and orchestration tools like Kubernetes.
- Strong knowledge of databases (SQL/NoSQL) and API design.
- Comfortable with CI/CD, Git, and Agile methodologies.
Bonus Skills:
- Experience with TypeScript and front-end frameworks like React.
- Experience with GraphQL.
- Knowledge of performance optimization and monitoring tools.
Why You Should Apply:
- Join a dynamic team working on high-impact projects.
- Work with the latest technologies and have ownership over key parts of the product.
- A collaborative, innovative environment with a focus on quality and craftsmanship.
Work Environment: We offer a flexible hybrid work environment for our employees in the San Francisco Bay Area, South Bay, and Peninsula regions. This means you can enjoy the best of both worlds — working from home some days, while also having the option to come into the office to collaborate with your team.
