Senior Platform Engineer

Loancrate is looking for a Senior Platform Engineer to build tooling and systems that let product engineers focus on shipping features fast without worrying about performance, reliability, or scale. As a Senior Platform Engineer at Loancrate, you'll ship platform improvements to production early and often, spanning infrastructure, developer tooling, and shared libraries.

Requirements

• Experience building internal platforms / developer tooling: code generation, CLIs, templates, shared SDKs, or frameworks that improve engineering velocity.
• Strong TypeScript skills and API design taste - you enjoy building stable primitives that other engineers rely on.
• Deep AWS experience across compute, networking, storage, and security (ECS, Lambda, VPC, ALB, IAM, RDS, ElastiCache, MSK, OpenSearch, S3, CloudWatch, CloudTrail, GuardDuty).
• Strong Terraform and/or Pulumi proficiency: modules, workspaces, and CI-driven plan/apply workflows.
• Experience designing and operating CI/CD systems that help large engineering teams ship frequently and confidently.
• Track record building production observability stacks (Datadog, CloudWatch, Sentry, distributed tracing, SLOs).
• You’ve built “paved roads” that bake in secure, reliable defaults (instrumentation helpers, policy-as-code, safe-by-default deployment patterns).
• Security-first mindset - you proactively harden infrastructure without slowing teams down.
• Aurora PostgreSQL operations at scale: backups, PITR, failover, read replicas, query tuning.
• Comfort with Docker and container orchestration environments.
• Reliability engineering mindset: SLOs, error budgets, incident response.
• Curiosity about the unique infrastructure demands of AI and LLM workloads.
• Strong written communication - you document decisions and help the team understand the systems they depend on.
