This role ensures backend systems are reliable, secure, and scalable while enabling consistent API behavior across clients.
This position partners closely with engineering, product, and design teams to translate high-level goals into durable backend solutions. In addition to hands-on development, the role contributes to architectural direction, long-term system health, and mentorship of other engineers.
Key Responsibilities
- Design, build, and maintain TypeScript-based backend services using Node.js
- Own and evolve RESTful APIs to support mobile and web applications
- Act as a system steward by identifying performance bottlenecks, reliability risks, and architectural gaps
- Collaborate cross-functionally to support new features and product initiatives
- Lead technical planning and backend design for complex or loosely defined problems
- Ensure system reliability through monitoring, debugging, and incident resolution
- Optimize database performance and data access patterns (MongoDB)
- Provide architectural guidance, code reviews, and mentorship to engineers
- Promote best practices around testing, documentation, and maintainability
Required Qualifications
- 8+ years of backend engineering experience, with deep hands-on work in TypeScript
- Strong experience designing, implementing, and maintaining production RESTful APIs
- Proven ability to operate independently on ill-defined or high-level goals
- Solid understanding of backend fundamentals, including:
- Experience supporting production systems and maintaining long-term system health
- Experience with MongoDB or other NoSQL databases
- API design
- Security considerations
- Performance and rate limiting
Preferred Qualifications
- Experience working in startup or small-team environments
- Database optimization experience (indexing, query tuning)
- Experience owning systems from initial design through production and ongoing maintenance
- Familiarity with CI/CD pipelines and deployment workflows
- Prior experience mentoring engineers or operating at a Staff-level scope
- Exposure to other backend languages (e.g., Go, Rust) is a plus but not required
Working Style & Values
- Strong engineering judgment with a focus on long-term, maintainable solutions
- Comfortable taking ownership and making decisions with limited direction
- Collaborative, product-minded approach to problem-solving
- Willingness to give and receive feedback (“strong opinions, weakly held”)
- Commitment to craftsmanship, continuous learning, and engineering excellence
