- Contribute to building a modern, best-in-class platform that handles time-critical workflows with precision and reliability.
- Conduct code reviews to ensure code quality, adherence to best practices, maintainability, and alignment with project requirements, while providing constructive feedback to team members across backend and frontend codebases.
- Ensure the delivery of high-quality software features within established timelines.

## WHAT WE'RE LOOKING FOR

- 4+ years of development experience in a fast-paced environment.
- Bachelor’s degree in computer science, computer engineering, or a related technical discipline, or equivalent industry experience.
- Experienced in building and maintaining end-to-end web applications using modern backend languages (e.g., Go, C#, Python) and frontend frameworks (e.g., React, TypeScript), with a strong focus on scalable architecture and user-centric design.
- Hands-on experience working with relational databases.
- Cloud experience, AWS preferred.
- Experience managing infrastructure and service configurations using Configuration as Code (e.g., Helm, Kustomize, Terraform).
- Deploy and operate backend services in a Kubernetes-based environment, optimizing for resiliency, scalability, and performance.
- Comfort collaborating across the stack, including working closely with design and product to translate requirements into user-facing functionality.
- Excellent written and verbal communication skills.
