About The Role

We are looking for a Senior Cloud Infrastructure Engineer to design, scale, and harden our multi-cloud infrastructure powering a microservices-based platform.

You will own infrastructure architecture decisions, drive platform reliability, and implement best-in-class DevOps and SRE practices. This role is not about keeping the lights on. It’s about redesigning the power grid while the city is running.

Key Responsibilities

Architecture & Platform Engineering

• Design and evolve secure, scalable infrastructure across Azure, AWS, and GCP
• Own infrastructure architecture for a microservices-based system
• Define and implement multi-cloud networking, IAM, and security boundaries
• Lead containerization and orchestration strategy (Kubernetes, managed services)
• Improve system resilience, fault tolerance, and disaster recovery posture
  
  

• Design high-availability systems with clear SLOs and SLAs
• Build observability frameworks (metrics, logs, traces)
• Lead incident response and post-incident improvements
• Optimize infrastructure cost, performance, and scalability
  
  

• Implement Infrastructure as Code (Terraform or equivalent)
• Build and optimize CI/CD pipelines across multiple cloud providers
• Automate provisioning, scaling, patching, and compliance controls
• Improve release reliability in microservices-heavy environments
  
  

• Implement cloud-native security controls and zero-trust principles
• Support compliance requirements typical in FinTech (SOC2, ISO, etc.)
• Harden infrastructure against vulnerabilities and misconfigurations
• Partner with security and engineering teams on secure architecture reviews
  
  

• Act as a technical authority in cloud infrastructure
• Mentor engineers and set infrastructure standards
• Drive platform engineering initiatives across teams
• Work closely with Product and Engineering leadership to align infrastructure with business goals
  
  

• Deep hands-on experience with at least two of the following: Azure, AWS, GCP
• Proven experience in companies operating microservices architectures at scale
• Background from established technology companies with mature engineering practices
• Strong Kubernetes experience (designing and operating production clusters)
• Infrastructure as Code expertise (Terraform preferred)
• Experience designing high-availability distributed systems
• Strong understanding of networking, IAM, cloud security, and cost optimization
  
  

• Experience in FinTech or SAAS environments
• Experience running multi-cloud environments in production
• Exposure to event-driven architectures (Kafka, Pub/Sub, etc.)
• Experience implementing SRE practices (SLOs, error budgets, incident management)
• Knowledge of compliance frameworks (SOC2, PCI-DSS, ISO 27001)
  
  

We cultivate a culture of innovation and collaboration, where your ideas matter. We empower our team members to take initiative, learn continuously, and thrive in a supportive environment.
