Infrastructure Team Lead

About the Role

We are looking for an experienced Infrastructure Team Lead to own the reliability, scalability, cost-efficiency, and performance of our infrastructure and platform systems. You will lead a team of infrastructure/DevOps engineers, set technical direction through architecture reviews, and drive a strong developer experience through robust CI/CD practices. This is a hands-on leadership role that blends technical depth with team management and cross-functional collaboration.

Key Responsibilities

1. Availability & Reliability (Target: 99.9% Uptime)

• Own the end-to-end reliability of production infrastructure and critical services.
• Design and implement high-availability architectures (redundancy, failover, load balancing, disaster recovery).
• Define and maintain SLIs/SLOs/SLAs; track error budgets and drive incident reduction.
• Lead incident response, root cause analysis (RCA), and post-mortems for outages or degradations.
• Establish and maintain on-call rotations, runbooks, and escalation procedures.

2. Architecture Review & Governance

• Lead and facilitate architecture review sessions for new systems, services, and major changes.
• Define infrastructure standards, best practices, and reference architectures (cloud, networking, security, data).
• Evaluate new technologies and tools; make build-vs-buy recommendations.
• Ensure scalability, security, and maintainability are considered in all infrastructure design decisions.
• Maintain up-to-date architecture documentation and diagrams.

3. Cost Optimization

• Monitor and manage cloud/infrastructure spend against budget; identify and eliminate waste.
• Implement cost governance practices (tagging, budgets, alerts, rightsizing, reserved/spot instance strategies).
• Regularly report on cost trends, savings initiatives, and ROI of infrastructure investments.
• Balance cost efficiency with performance and reliability requirements.

4. Performance & Application Performance Monitoring (APM)

• Implement and maintain observability stack (metrics, logging, tracing) using Grafana and Elastic APM.
• Proactively identify performance bottlenecks across infrastructure, network, and application layers.
• Define performance benchmarks and drive continuous improvement initiatives.
• Partner with engineering teams to optimize application and infrastructure performance.

5. CI/CD & Developer Experience

• Own and continuously improve CI/CD pipelines (GitHub Actions, Jenkins) to increase deployment speed, frequency, and reliability.
• Champion Infrastructure as Code (IaC) practices using AWS CDK and Terraform.
• Reduce friction in the developer workflow — build tools, self-service platforms, and automation that improve engineering velocity.
• Establish standards for environments (dev/staging/prod), branching strategies, and release management.
• Gather feedback from engineering teams and iterate on internal developer platforms/tools.

6. Team Leadership

• Manage, mentor, and grow a team of infrastructure/DevOps/SRE engineers.
• Set team goals aligned with business priorities; conduct performance reviews and career development planning.
• Foster a culture of ownership, blameless post-mortems, and continuous improvement.
• Collaborate with Engineering, Security, Product, and Finance stakeholders.

Requirements

Experience

• 5+ years in Infrastructure, Platform Engineering, SRE, IMOC center and including 2+ years in a lead or management role.
• Proven experience designing and operating highly available, production-grade systems at scale.
• Track record of driving cost optimization initiatives in cloud environments (AWS/GCP).
• Hands-on experience with observability/APM tools and performance tuning.
• Strong background building and maintaining CI/CD pipelines and IaC.

Technical Skills

• Cloud platforms: AWS, GCP (certification a plus).
• Containerization & orchestration: Docker, Kubernetes.
• IaC tools: Terraform, CDK or similar.
• CI/CD tools: GitHub Actions, Jenkins or similar.
• Monitoring/APM: Prometheus, Grafana, Elasticsearch or similar.
• Scripting/automation: Python, Bash, or Go.
• Strong understanding of networking, security, and system architecture principles.

Soft Skills

• Strong leadership, communication, and stakeholder management skills.
• Ability to balance competing priorities (reliability vs. cost vs. speed).
• Data-driven decision-making and comfort with metrics/reporting.
• Mentorship mindset and ability to build strong engineering culture.

Nice to Have

• Experience with FinOps practices/tools.
• Experience in a regulated or high-scale industry (fintech, e-commerce, SaaS).
• Relevant certifications (AWS Solutions Architect, CKA, etc.).

What We Offer

• Build products used by tens of thousands of businesses.
• Ship code that reaches customers quickly.
• High ownership with minimal bureaucracy.
• Learn from experienced engineers and product leaders.
• Flexible work hours and 45 days/year work from anywhere.
• Competitive compensation, health & accident insurance from day one.
• 17–19 public holidays, 12 personal leave days, and 8 annual leave days.
• A friendly, collaborative team that genuinely enjoys building together.
• Clear opportunities to grow your career as the company scales.
