What We Are Looking For

We are seeking a highly motivated and experienced Principal Software Engineer to join our growing team. In this role, you will play a critical part in designing, developing, and maintaining our core platform, with a strong emphasis on backend systems and architecture. While the role is backend-leaning, an appreciation for clean, intuitive user experiences and collaboration with engineers and designers is highly valued.

You’ll work across the full scope of our product, partnering closely with other senior engineers, product managers, and designers in a fast-paced, agile environment. A key aspect of this role includes direct interaction with our customers—understanding their challenges and helping translate their needs into thoughtful, scalable technical solutions.

This is primarily an individual contributor role, but it also involves providing technical leadership. There is potential for rapid advancement, with the opportunity to transition into a Head of Engineering or CTO role within 6 to 12 months, depending on performance and company growth.

Collaborate closely with product managers, designers, and other senior engineers in an agile environment to translate business requirements and customer feedback into technical solutions. This will include direct interaction with customers to understand their pain points and needs.
Develop, deploy, and maintain robust React-based embedded widgets designed for seamless integration into diverse customer websites, ensuring compatibility and performance across various environments.
Identify and proactively address potential challenges and limitations associated with deploying embedded software onto external websites, such as handling conflicts with existing site scripts, managing CSS encapsulation, and ensuring smooth interoperability with third-party website components.
Participate in code reviews, providing constructive feedback to ensure code quality and consistency across the team.
Troubleshoot and debug complex issues, identifying root causes and implementing effective solutions.
Contribute to the improvement of our development processes, including CI/CD pipelines, testing frameworks, and coding standards.

Proactively identify and address technical debt and ensure long-term maintainability of the codebase.
Work within an AWS environment, leveraging its services to build and deploy scalable solutions.
