e Planet Group has partnered with a Boston area company to locate a full-stack developer with strong backend Node.js skills for a full-time role.

This is a hybrid role and candidates should expect to be onsite three days a week.

The ideal candidate will be a Senior Engineer who thrives in early-stage environments and enjoys building meaningful products from the ground up. This role is ideal for an engineer who is strongest on the backend but comfortable contributing to modern frontend applications.

You'll play a key role in shaping the architecture and feature development of a high-impact SaaS platform, working closely with a small, collaborative engineering team. This is a hands-on position with high ownership, direct product influence, and significant technical autonomy.

If you enjoy solving complex backend challenges while still contributing to user-facing experiences, this is the right opportunity.

• Develop and maintain infrastructure in AWS (Lambda, ECS, API Gateway, RDS, IAM, etc.)
• Manage cloud environments using Infrastructure as Code (Terraform, CloudFormation, or CDK)
• Improve system scalability, caching strategies, and overall performance
• Contribute to product direction and technical decision-making in a small, high-impact team
• Occasionally collaborate cross-functionally and support customer-facing discussions when needed
