Infrastructure & Reliability Engineer Company: Circles – Jetpac Location: Delhi-NCR or Pune (Hybrid) Type: Full‑time About Jetpac Jetpac, from Circles, is building a seamless way for travelers to stay connected globally. We offer eSIMs across 200+ destinations with a fast-growing consumer platform spanning web, mobile, and partner channels targeting the travel essentials segment. We operate as a high-velocity product team. Small teams, fast decisions, and direct ownership. We ship continuously, iterate quickly, and measure what matters. The Role We've reached meaningful scale and are rebuilding key parts of the platform to support the next phase of growth. You'll work closely with platform, backend, and product teams to ensure systems are reliably deployed, secure, and observable in production. The way infrastructure is built and operated has fundamentally changed. Static scripts and manual operations don't scale in AI-assisted engineering environments. This role focuses on building and operating AI-accelerated infrastructure systems that are reliable by design. You'll work across cloud, backend, and runtime systems to ensure production readiness through: reliable infrastructure and deployments strong observability and debugging capabilities secure-by-default system design This is not a traditional DevOps role. You are accountable for how systems run in production, not just how they are deployed. What You'll Do Build and operate infrastructure systems that are reliable, secure, and scalable across backend, web, and mobile platforms. Own production infrastructure across cloud, networking, and runtime environments Work with platform engineering to deploy and operate services reliably Build and maintain infrastructure-as-code and CI/CD pipelines Implement observability systems (logs, metrics, tracing) with meaningful alerting Ensure system reliability and uptime, including incident response and postmortems Apply infrastructure security best practices (IAM, secrets, network isolation, patching) Improve system performance, cost efficiency, and operational simplicity Use AI-assisted workflows to accelerate infrastructure development, debugging, and operations Focus areas include: Service deployment and runtime reliability Observability across user journeys (browse → cart → checkout → payments) Infrastructure performance, scaling, and cost optimization Secure infrastructure foundations across environments Required Skills and Experience 3–5 years of experience in infrastructure, SRE, or backend/platform-heavy roles Strong hands-on experience with AWS cloud platforms Experience with infrastructure-as-code (Terraform, CloudFormation) Experience building and operating CI/CD pipelines and deployment systems Hands-on experience with observability tools (Prometheus, Grafana, ELK, etc.) Strong understanding of networking fundamentals and distributed systems Experience implementing infrastructure-level security best practices Comfortable debugging production issues across multiple layers (infra, backend, APIs) Experience with AI-assisted workflows, including: Using AI tools to generate infra code, debug issues, and automate workflows Validating and refining AI-generated outputs for correctness and reliability Building repeatable systems using AI without compromising production safety Example Projects You'll Work On Build a production-grade observability stack across services and user flows Design and improve deployment pipelines for faster and safer releases Implement secure infrastructure foundations (IAM, secrets, network isolation) Improve system reliability and reduce incident frequency across critical flows Optimize infrastructure for performance and cost at scale What Success Looks Like Systems are reliable, observable, and easy to debug in production Incidents are reduced, and recovery is fast when they happen Deployments are safe, repeatable, and low-friction Engineers trust infrastructure and can ship without operational bottlenecks Security best practices are implemented by default, not as an afterthought Hiring Process Technical Intro Conversation with CTO Live Practical Assignment (focused on test systems + AI usage) Why Jetpac High ownership, low bureaucracy Real product impact at global scale Fast-moving team with strong engineering culture Flexible work setup across global teams Circles is committed to a diverse and inclusive workplace.
