About the position

As a Backend Engineer in one of our AI-focused teams, you will help build intelligent, AI-powered features that enhance how sales teams work. You’ll develop and maintain serverless, event-driven systems and APIs that integrate with third-party services. Working closely with senior engineers, you’ll take ownership of well-scoped features and contribute to technical and product discussions, helping design solutions that use modern AI capabilities to deliver real value to users. Rather than a monolithic environment, you’ll work within an ecosystem of services and help improve their reliability and quality. Your work will shape the end-user experience for all our customers.

Key Responsibilities

- Build AI-powered features that use large language models to automate and enhance user workflows.

- Contribute to improving our development processes and environments.

- Build and maintain integrations with third-party platforms and APIs.

- Help implement and maintain our growing ecosystem of microservices.

- Work in teams where code reviews and pair programming are part of our strong engineering culture, learning from experienced engineers and sharing what you know.

- Apply a security-first approach to the features and changes you deliver.

- Grow your technical and architectural skills through mentoring from senior engineers, and support more junior colleagues where you can.

- Keep the bigger picture in mind, because your work will reach 100,000 users globally.
