Technical Tools

EngineeringDevops Engineer

This is a senior engineering opportunity focused on the reliability, performance, and delivery of a widely used network automation platform.
You will help own the path from core software releases through dependable production deployments across cloud and self-managed environments.
The role combines software engineering, SRE, platform engineering, observability, and supply chain security.
You will work hands-on with technologies including AWS, Kubernetes, Terraform, PostgreSQL, GitHub Actions, and monitoring platforms.
As an early member of a new team, you will have meaningful influence over engineering practices, release processes, and operational standards.
You will collaborate across engineering teams, lead reliability initiatives, and address production issues at their technical source.
The environment values technical ownership, simplicity, open-source collaboration, clear communication, and continuous improvement.

Own and improve the software build and release pipeline, from container base images through availability across cloud and enterprise deployments.
Establish reliable release handoffs between core engineering and downstream cloud and enterprise teams so releases reach customers efficiently and predictably.
Improve application performance and production reliability, including startup behavior, PostgreSQL performance, and other critical system components.
Build and maintain comprehensive observability for both the application and release pipeline, including monitoring, alerting, and service-level objectives (SLOs).
Serve as an escalation point for performance and reliability incidents, identifying root causes and contributing fixes to the underlying application when appropriate.
Strengthen software supply chain security and contribute to controls supporting SOC 2 compliance for the build and delivery pipeline.
Participate in on-call rotations, lead incident response for relevant issues, and facilitate effective postmortems and follow-up improvements.
Drive cross-team engineering initiatives from technical proposals and RFCs through implementation, migration, and adoption.
