About Leapfrog

Leapfrog is on a mission to be a role model technology company. Since 2010, we have relentlessly worked on crafting better digital products with our team of superior engineers. We’re a full-stack company specializing in SaaS products and have served over 100 clients with our mastery of emerging technologies.

Hundreds of companies in Boston, Seattle, Silicon Valley, and San Francisco choose us to gain speed, agility, quality, and stability, giving them an edge over their competitors.

About the role

We are looking for a Full Stack Engineer who is equally comfortable writing backend and frontend application code and deploying those applications on AWS. This role requires strong programming fundamentals, hands-on experience with modern JavaScript frameworks (like React), and the ability to use AWS services to host and scale applications.

Job Description

  • Design and build scalable full stack applications using React (frontend) and Node.js/Python/Go (backend).

  • Deploy and manage applications on AWS using services like Lambda, API Gateway, S3, DynamoDB, RDS, ECS, etc.

  • Work with Infrastructure as Code tools such as AWS CDK, Serverless Stack (SST), or Terraform to automate infrastructure.

  • Own the entire lifecycle of your features – from coding and testing to deployment and observability.

  • Collaborate with product, design, and other engineering teams in an agile environment

Job requirements

  • 5+ years of hands-on coding experience in modern application frameworks (e.g., Node.js, Python, or Go).

  • Proficiency in JavaScript/TypeScript and experience with React.

  • Experience writing and deploying code to AWS, not just using infrastructure tools.

  • Solid understanding of cloud-native architectures, event-driven design, and serverless technologies.

  • Strong foundation in data structures, algorithms, and application design patterns.

  • Ability to work independently and own features end to end.


Nice to have

  • Experience with AWS CDK or SST.

  • Exposure to CI/CD pipelines (e.g., GitHub Actions, GitLab CI).

  • Experience with full-stack performance tuning and application observability tools.

Soft Skills

  • Strong problem-solving skills and attention to detail.

  • Ability to work independently with minimal supervision.

  • Effective communication and team collaboration.
