Summary
Senior DevOps Engineer owning AWS infrastructure end-to-end for Big Happy's ad-tech platform from Panchkula: building CI/CD pipelines, driving cloud cost optimization, setting up monitoring/observability, managing security and infrastructure-as-code (Terraform/CloudFormation), and mentoring engineers. Hours must align with US time zones (EST/EDT and PST/PDT).
BigHappy is looking for a Senior DevOps Engineer to own our AWS infrastructure end-to-end and be the driving force behind reliable deployments, cost-efficient cloud operations, and strong observability across our engineering platform. This is a senior role: In collaboration with Director - Engineering, you'll make architectural decisions on infrastructure, build the systems that keep our ad-tech platform running smoothly, and help other engineers get better at owning their own monitoring and operational health.
You'll work closely with the Panchkula engineering teams (Go, Node.js, React,Javascript,linux) to build infrastructure that scales with a fast-moving ad-tech business, while keeping a close eye on cloud spend and security posture.
NOTE:
- Candidates must be open to work within USA time zones EST/EDT and PST/PDT hours.
- Review, improve, and manage our AWS cloud infrastructure end-to-end, including compute, networking, storage, and data services.
- Design, build, and maintain CI/CD pipelines that make deployments smooth, fast, and reliable across services.
- Drive cloud cost optimization on an ongoing basis
- right-sizing resources, reserved/spot instance strategy, cleaning up unused resources, and building cost monitoring dashboards that keep spend visible to the team.
- Set up and maintain monitoring and alerting across services (infrastructure, application, and pipeline health), so issues are caught before they become incidents.
- Own infrastructure security and continuous maintenance: patching, vulnerability scanning, IAM hygiene, and basic compliance practices.
- Build monitoring dashboards and workbooks, but just as importantly, coach and enable engineering teams to own their own dashboards and act independently on what they see.
- This role is expected to make itself less of a bottleneck over time, not more of one.
- Implement and maintain infrastructure-as-code (Terraform and/or CloudFormation) so environments are reproducible, versioned, and auditable.
- Support containerization and orchestration (Docker, and Kubernetes where applicable) for services that need it.
- Participate in and support incident response.
- troubleshooting, root-cause analysis, and post-incident follow-through.
- Own backup and disaster recovery planning, and make sure it's actually tested, not just documented.
- Write and maintain clear runbooks and documentation so operational knowledge doesn't live only in one person's head.
- Mentor and guide other engineers on monitoring, observability, and general operational best practices.
A note on scope: This is a DevOps/infrastructure-first role, not a hybrid DevOps-developer role. That said, if bandwidth allows, there may occasionally be opportunities to contribute to feature development. So genuine hands-on coding ability (not just scripting) is a plus, though it's secondary to the core mandate above.
Must-Have Skills
- 5+ years of hands-on experience managing AWS infrastructure in production environments.
- Strong experience with CI/CD tooling (Jenkins, GitHub Actions, GitLab CI, or similar).
- Deep familiarity with infrastructure-as-code tools (Terraform and/or CloudFormation).
- Solid experience with monitoring/observability stacks (e.g., CloudWatch, Prometheus/Grafana, Datadog, or similar) and setting up alerts that people actually trust and act on.
- Strong grounding in cloud security best practices.
- IAM policies, vulnerability management, patching cadences, and general security hygiene.
- A track record of driving measurable cloud cost optimization initiatives, not just running cost reports.
- Working knowledge of containerization and orchestration (Docker; Kubernetes experience is a strong plus).
- Comfortable working independently and making infrastructure/architectural decisions with appropriate judgment on when to loop in others.
- Strong communication skills — this role interfaces heavily with other engineers on monitoring ownership and requires influencing without direct authority. You'll need to explain infrastructure and cost tradeoffs clearly to people who aren't infrastructure specialists.
Nice-to-Have Skills
- Hands-on coding ability beyond scripting (Go, Node.js, or similar), with genuine interest in occasionally contributing to feature work.
- Experience in ad-tech, martech, or another high-throughput, latency-sensitive domain.
- Experience setting up cost-monitoring dashboards or FinOps practices from scratch.
- Prior experience mentoring or upskilling engineers on operational/monitoring practices.
- Experience with multi-region or high-availability AWS architectures.
