DevOps Engineer, India

This is a remote position. IMPORTANT: PLEASE READ BEFORE APPLYING To be considered, you must follow the How to Apply instructions at the end of this job description and complete the Signalmash application form. Applications that do not include the completed form will not be reviewed. Automated or bulk applications that do not follow these instructions will be disregarded. About Signalmash Signalmash operates a cloud communications platform that enables businesses to manage and deliver RCS, SMS, and MMS messaging through carrier and technology-provider integrations. The platform includes customer onboarding, messaging APIs, routing, compliance, vendor integrations, usage tracking, and billing. As the platform and engineering organization grow, we are adding an India-based DevOps Engineer to own the reliability, speed, and security of the infrastructure the platform runs on. The Role The DevOps Engineer will own our build, deploy, and runtime infrastructure across self-managed Kubernetes and cloud environments. You will make deploys faster and safer, make failures visible before customers see them, and make recovery a tested procedure rather than a hope. This is a hands-on role combining CI/CD ownership, Kubernetes operations, database reliability, observability, and security hardening. You will work alongside internal engineers and external development partners, and connect with the US management team on priorities, risks, and incidents. This is not a ticket-taking position. The successful candidate must be comfortable reading application code and logs, tracing a failure across services, and owning a production issue from alert to documented root cause. Key Responsibilities Own CI/CD pipelines end to end using GitHub Actions, including self-hosted runner infrastructure, build speed optimization, caching, elimination of flaky jobs, and safe automated deployments. Operate and improve Kubernetes environments (self-managed K3s on bare metal) and cloud deployments (GCP).
