Job Description

We're looking for a (Senior) Software Engineer to take end-to-end ownership of building and scaling our core product systems.

• Design scalable backend services with NestJS/Node.js, create frontend experiences with Next.js/React, and architect data models with MongoDB

• Build and consume APIs, integrating with internal and external systems while collaborating with and guiding other engineering teams

• Own your deployments, build CI/CD pipelines, manage infrastructure as code, and maintain applications in production

• Drive code quality through testing, code reviews, and continuous integration, setting standards for the team

• Monitor systems, optimize performance, troubleshoot complex issues, and make architectural decisions for scalability

• Mentor mid-level and junior engineers, foster a culture of clean code and best practices, and lead by example in technical discussions

Qualifications

Required:

• 5+ years of professional software development experience

• Strong proficiency in TypeScript and Node.js, or solid experience with other modern languages and willingness to learn our stack

• Hands-on experience with infrastructure as code tools (Terraform, Pulumi, etc.)

• Strong experience building CI/CD pipelines (GitHub Actions, Azure DevOps, etc.)

• Cloud platform experience (Azure preferred, but AWS/GCP transferable)

• Experience with containerization and orchestration (Docker, Kubernetes)

• Experience with monitoring, observability, and performance optimization tools

• Experience designing system architecture for high-scale applications
