About Our Team and Your Role

The Engineering Team works closely with stakeholders across the organization to deliver solutions to both internal and external customers. We have been a fully remote team for over 12 years. We adhere to a loose agile process (not scrum) using a kanban board and an automated CI/CD pipeline. We’re a small team, but we deliver big results. We care about writing quality code and taking the time to balance immediate business needs with long-term, technical costs.

As our Software Engineer you will be:

  • Working closely with Senior Staff engineers to design, develop, maintain, and deliver full stack products for both internal and external customers.
  • Working in an agile environment with a team that deploys multiple times a day.
  • Contributing to process improvements, best practices, tooling, and engineering strategy.
  • Working in close partnership with cross-functional teams and management to advance Mantis’ vision.

  • MySQL (or other relational databases), Redis, Elasticsearch
  • GCP, Kubernetes (GKE), Terraform, Docker
  • Sidekiq
  • Rspec, CircleCI
  • Slack, Jira

What You Need

  • 3+ years of experience shipping high-quality, non-trivial Rails applications.
  • Strong grasp of Computer Science concepts, such as object-oriented design, data structures, general understanding of algorithmic complexities, etc.
  • Strong relational database skills such as schema design, query building and optimization.

 Additional Skills

  • Desire to build reliable, maintainable software rather than haphazardly shipping features.
  • Experience with continuous integration and writing meaningful, non-brittle tests.
  • Ability to communicate clearly with both technical and non-technical people.
  • Be self-driven and comfortable working in a remote team environment.
  • Have excellent analytical and problem-solving skills.
  • Thrive in a collaborative and dynamic environment involving diverse stakeholders and subject matter experts.

 Nice To Haves

  • Experience with GCP, Kubernetes, and Terraform (or similar technologies).
  • Desire to mentor more junior engineers.
