Role Description As a Senior Full Stack Engineer on the Conversation Intelligence team, you'll be at the heart of Chorus.ai, ZoomInfo's Conversation Intelligence platform. Chorus processes and analyzes a tremendously large set of sales calls to surface insights that help salespeople perform at their highest level and match the best in the industry. You will own customer-facing product areas — from AI-powered tooling to rich data visualizations and charting experiences — working across the full stack and architecting solutions capable of handling millions of customer requests per day. Frontend-heavy or backend-heavy, it doesn't matter — as long as you're great at what you do, willing to learn, and comfortable taking on basic tasks outside your primary discipline when needed, there's meaningful work for you here. You'll be surrounded by incredibly smart, talented, and motivated engineers who will push you to define your new best, all working toward ambitious goals that actually move the needle. What You’ll Do: - Design, prototype, and deliver customer-facing features across the full stack — from responsive, polished UI components to robust REST APIs and backend services. - Build and iterate on AI-powered tools that make Chorus's vast dataset of sales conversations more digestible and actionable for our users. - Provide technical leadership — contribute to architectural decisions, conduct meaningful code reviews, and help raise the bar for engineers around you. - Work with engineers, designers, and Product Managers to break down roadmap initiatives into well-scoped, executable work. - Test, document, and maintain a codebase that is an example to our engineers and supports the scale of the business. Qualifications - 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. - Strong interpersonal and communication skills; highly responsible, enthusiastic, and thorough. - Ability to take end-to-end ownership — from problem framing through to production delivery. Benefits - Comprehensive benefits including holistic mind, body, and lifestyle programs designed for overall well-being. - Actual compensation offered will be based on factors such as the candidate’s work location, qualifications, skills, experience and/or training. - US base salary for this position: $161,360 — $242,040 USD. - Additional compensation such as Bonus, Commission, Equity, and other benefits may also apply.
