Build software that matters, take real technical ownership, and use modern AI tooling to do your best work. This is a hands-on senior engineering role for someone who enjoys solving complex product problems, shaping robust solutions, and helping teams deliver reliable services at scale. You’ll work on secure, scalable microservices and APIs using TypeScript, AWS, and modern engineering practices.

You’ll play a leading role within a collaborative product engineering team, owning complex features end to end, contributing to design and architectural decisions, supporting production systems, and helping raise the bar across backend, cloud, and AI-assisted development workflows.

Key Responsibilities:

  • Use AI tools to accelerate coding, debugging, testing, research, and documentation, while validating outputs carefully and applying sound judgment.
  • Strengthen service reliability, observability, and engineering quality by improving monitoring, incident response, testing, and development practices.

Qualifications:

  • 5 to 8 years of professional software engineering experience delivering production systems in an agile environment.
  • Hands-on experience with AWS or other cloud-native development, automated testing, and deployment practices that support reliable delivery.
  • Comfort working with SQL databases, Git, Docker-based workflows, and modern CI/CD pipelines.
  • Practical understanding of AI-assisted engineering tools and broader LLM concepts, with the judgment to use them responsibly with privacy, security, cost, and quality in mind.

It would be great if you had these too, but we’ll support you if you don’t:

  • Familiarity with infrastructure as code, for example CDK or Terraform.
  • Exposure to observability tooling, incident response, or production monitoring practices.
  • Experience working with React or Angular when contributing to end-to-end product delivery.
