Job description

Job Description

Insight Global is seeking a Senior Ruby Developer to join a growing application engineering team responsible for supporting and enhancing critical enterprise applications. This role is ideal for a developer with recent Ruby on Rails experience who is comfortable operating within production environments and partnering closely with SRE, DevOps, and Platform Engineering teams.

The ideal candidate combines strong Ruby development expertise with hands-on experience supporting highly available systems, leveraging observability tools, and driving application reliability. Experience with Dynatrace is highly preferred, while exposure to tools such as Splunk, New Relic, Datadog, or similar monitoring platforms is also valuable.

The Senior Ruby Developer will be responsible for designing, developing, and supporting enterprise applications using Ruby on Rails while ensuring high levels of performance, reliability, and scalability. This individual will work closely with SRE, DevOps, and Infrastructure teams to build and maintain production-ready solutions, enhance application observability through tools such as Dynatrace and Splunk, and proactively monitor system health and performance. The role involves troubleshooting production issues, optimizing application performance, developing RESTful APIs and backend services, participating in code reviews and architectural discussions, and contributing to CI/CD and automation initiatives. The successful candidate will play an active role in supporting critical production systems, participating in on‑call rotations, and partnering across engineering teams to improve operational excellence and overall platform stability within an Agile development environment.

We're looking for a Ruby developer who enjoys solving production challenges as much as building new features. The ideal candidate has recent Ruby on Rails experience, strong AWS and Kubernetes knowledge, and a passion for application observability, monitoring, and operational excellence. They are comfortable partnering with SRE and DevOps teams, supporting production systems, and using tools such as Dynatrace and Splunk to improve application performance and reliability.
