DevOps Engineer, India

Signalmash; India; Hybrid; INR 900,000 - 1,500,000; Full time

Job summary

Signalmash is hiring an India-based DevOps Engineer to own the reliability, speed, and security of the platform’s infrastructure across self-managed Kubernetes and cloud environments. You will optimize CI/CD, manage Kubernetes, and ensure robust PostgreSQL operations with backup and recovery protocols.

The role requires deep Kubernetes experience, strong Linux, scripting, and cloud skills, plus hands-on use of AI coding tools and a commitment to keeping a live customer-facing system resilient

Qualifications

• 4+ years in DevOps, SRE, or platform engineering with production ownership.
• Strong Kubernetes experience — deployment, networking, storage, and upgrades — ideally including self-managed or bare-metal clusters.
• CI/CD depth with GitHub Actions or equivalent, including runner infrastructure and pipeline optimization.
• PostgreSQL administration, including migrations and tested backup/restore.
• Docker, Linux administration, shell scripting, and at least one of Python or Node.js.
• Cloud experience with GCP or transferable AWS/Azure experience.
• Monitoring and alerting stacks such as Prometheus/Grafana or equivalents.
• A track record of keeping a live, customer-facing platform up through continuous change.
• Practical experience using AI coding tools in real repositories, including testing, review, and security controls.
• Strong spoken and written English.
• Based in India and able to work until approximately 11:30 PM IST to overlap with the US management team.

Responsibilities

• Own CI/CD pipelines end to end: GitHub Actions (including self-hosted runner infrastructure), build speed, caching, elimination of flaky jobs, and safe automated deploys.
• Operate and improve our Kubernetes environments (self-managed K3s on bare metal) and cloud deployments (GCP), including environment parity from development through production.
• Manage PostgreSQL operations: schema migrations, backup and point-in-time recovery, and performance.
• Build and maintain observability: metrics, logs, and alerting that page the team before customers notice.
• Own backup and disaster recovery: automated offsite backups, periodic restore verification, and documented runbooks.
• Harden security: secrets management, network segmentation and overlay networking (Tailscale/WireGuard-style), TLS and certificate management, least-privilege access, and dependency hygiene.
• Coordinate production incidents and ensure root causes, corrective actions, and lessons are documented.
• Reduce infrastructure cost without reducing reliability.
• Introduce responsible AI-assisted operations practices using tools such as Claude Code, Codex, Cursor, or Copilot.

Job description

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.

The Role

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 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: GitHub Actions (including self-hosted runner infrastructure), build speed, caching, elimination of flaky jobs, and safe automated deploys.
• Operate and improve our Kubernetes environments (self-managed K3s on bare metal) and cloud deployments (GCP), including environment parity from development through production.
• Manage PostgreSQL operations: schema migrations, backup and point-in-time recovery, and performance.
• Build and maintain observability: metrics, logs, and alerting that page the team before customers notice.
• Own backup and disaster recovery: automated offsite backups, periodic restore verification, and documented runbooks.
• Harden security: secrets management, network segmentation and overlay networking (Tailscale/WireGuard-style), TLS and certificate management, least-privilege access, and dependency hygiene.
• Coordinate production incidents and ensure root causes, corrective actions, and lessons are documented.
• Reduce infrastructure cost without reducing reliability.
• Introduce responsible AI-assisted operations practices using tools such as Claude Code, Codex, Cursor, or Copilot.

Required Experience

• 4+ years in DevOps, SRE, or platform engineering with production ownership.
• Strong Kubernetes experience — deployment, networking, storage, and upgrades — ideally including self-managed or bare-metal clusters, not only managed cloud services.
• CI/CD depth with GitHub Actions or equivalent, including runner infrastructure and pipeline optimization.
• PostgreSQL administration, including migrations and tested backup/restore.
• Docker, Linux administration, shell scripting, and at least one of Python or Node.js.
• Cloud experience with GCP or transferable AWS/Azure experience.
• Monitoring and alerting stacks such as Prometheus/Grafana or equivalents.
• A track record of keeping a live, customer-facing platform up through continuous change.
• Practical experience using AI coding tools in real repositories, including testing, review, and security controls.
• Strong spoken and written English.
• Based in India and able to work until approximately 11:30 PM IST to overlap with the US management team.

Preferred Experience

• Communications or CPaaS platform operations: messaging APIs, carrier integrations, high-throughput webhooks and queues.
• Hybrid estates combining bare-metal providers (such as Hetzner) with cloud.
• Cloudflare (DNS, R2 object storage), GitOps patterns (ArgoCD/Flux), and infrastructure as code.
• ORM-driven migration workflows (Prisma or similar) and the failure modes that come with them.
• Quantifiable cost-optimization wins.
• Security- or compliance-sensitive environments (SOC 2 or similar).

Location

The position is based in India and may initially be remote. Signalmash is evaluating an engineering office in Kochi during 2026-2027. Candidates should be open to relocating to Kochi if an office is established.
