What You Bring:

• 5–10 years of relevant software engineering experience building production web applications
• Strong proficiency in either backend (Python, Node.js) or frontend (React, Angular) development as your primary discipline
• Working knowledge of — or genuine eagerness to learn — the other side of the stack: backend services and APIs, or frontend frameworks and UI development
• Hands-on experience with relational and NoSQL databases: MySQL, MongoDB, DynamoDB
• Familiarity with search technologies: Elasticsearch and/or Solr
• Experience with RESTful API design and backend service development
