Senior Platform Engineer

inKind is a growing financial and hospitality technology platform seeking a Senior Platform Engineer. The role involves owning and evolving the cloud infrastructure, ensuring systems are secure and reliable, and leading architectural decisions to support the platform's growth.

Responsibilities:

• Own and evolve our AWS infrastructure across compute, networking, storage, and managed services
• Design and maintain infrastructure that supports high availability, predictable performance, and financial correctness
• Lead platform-level architectural decisions, including service migrations and runtime changes (e.g., Redis → Valkey, EKS → ECS/Fargate)
• Ensure infrastructure choices align with reliability, cost, and operational simplicity—not just trend adoption
• Design and maintain deployment pipelines that are safe, repeatable, and observable
• Own system reliability through capacity planning, failure modeling, and controlled change management
• Lead incident response and root-cause analysis for infrastructure-level failures
• Participate in on-call rotations and continuously improve operational ergonomics
• Build and maintain strong observability across infrastructure and services (metrics, logs, tracing, alerting)
• Ensure secure configuration of AWS resources, IAM policies, secrets management, and network boundaries
• Proactively identify infrastructure risks related to scale, cost, or security and address them before they become incidents
• Partner closely with application engineers to ensure platform constraints and capabilities are well understood
• Drive infrastructure changes through hands-on implementation
• Establish standards and best practices for infrastructure, deployment, and operations as the team grows
• Mentor other platform engineers and help raise the overall operational maturity of the organization

Requirements:

• 8+ years of experience building and operating production infrastructure in cloud environments
• Deep experience with AWS core services (EC2, ECS/EKS, VPC, IAM, RDS, ElastiCache, ALB/NLB, CloudWatch, etc.)
• Strong understanding of containerized workloads and orchestration tradeoffs
• Proven experience designing systems for high availability, fault tolerance, and controlled failure
• Hands-on experience with infrastructure as code (Terraform, CloudFormation, or equivalent)
• Demonstrated ability to plan and execute infrastructure migrations safely
• Experience debugging real production incidents involving networking, scaling, or service degradation
• Experience operating infrastructure for financial systems or other high-reliability domains
• Firsthand experience scaling infrastructure through periods of rapid growth
• Strong opinions about observability and operational hygiene, informed by past failures
• Experience simplifying, retiring, or rearchitecting over-engineered infrastructure
• Comfort working closely with a Rails-based application stack while remaining tool-agnostic
