Senior Software Engineer

Location: Toronto, Ontario, Canada

Department: 933 Engineering - ZI Products

ZoomInfo is where careers accelerate. We move fast, think boldly, and empower you to do the best work of your life. You'll be surrounded by teammates who care deeply, challenge each other, and celebrate wins. With tools that amplify your impact and a culture that backs your ambition, you won't just contribute. You'll make things happen—fast.

As a Senior Full Stack Engineer on the Chorus Engagement 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. We generate deal insights, risk signals, and next-step recommendations that make Chorus an indispensable tool for any data-driven sales team. 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

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
• Strong interpersonal and communication skills; highly responsible, enthusiastic, and thorough
• Ability to take end-to-end ownership — from problem framing through to production delivery
