[Hiring] Senior Software Engineer @Loancrate

Role Description

Our dreams are big and we have much to build! We’re looking for someone to build the tooling and systems that let product engineers focus on shipping features fast - without having to worry about performance, reliability, or scale. This role spans infrastructure and internal developer tooling: you’ll design self-serve platforms, libraries, and automation that “just work,” enabling complex product experiences without compromising security or uptime.

What To Expect

• Ship platform improvements to production early and often - spanning infrastructure, developer tooling, and shared libraries.
• Dive into mission-critical work such as:
  • Designing and building the systems that let engineers deploy dozens of times per day with confidence.
  • Creating self-serve developer experiences - local dev tooling, templates, golden paths, and CI-integrated workflows.
  • Pioneering tooling and best practices for AI-first software engineering.
  • Extending our internal TypeScript tooling for faster feature building.
  • Making Loancrate's platform observable and self-healing.
  • Baking security into our platform defaults.
  • Solving interesting scaling problems as our AI-native mortgage platform grows.

Core Responsibilities

• Own and evolve our AWS infrastructure using Terraform and Pulumi Cloud.
• Design and maintain internal developer tooling and libraries.
• Create and maintain golden paths for common workflows.
• Build and maintain CI/CD pipelines and per-PR ephemeral environments.
• Drive reliability through SLOs, auto-scaling, incident response, and postmortems.
• Create observability tooling and shared instrumentation libraries.
• Enforce security best practices across IAM, secrets management, and encryption.
• Own the reliability and performance of our data platform (Aurora PostgreSQL).
• Reduce toil through automation and self-service tooling.
• Contribute to architecture decisions and documentation.

Tech Stack

• AWS infrastructure managed with Terraform and Pulumi Cloud.
• Application services run in Docker on ECS EC2 or Fargate.
• Key services include Aurora PostgreSQL, ElastiCache (Redis), MSK (Kafka), and OpenSearch.
• CI/CD runs on Buildkite with TypeScript pipeline-as-code.
• Internal TypeScript platform libraries for consistent APIs and developer workflows.
• Observability powered by Datadog, CloudWatch, and Sentry.
• DNS and CDN handled by Cloudflare.
• Application code is a TypeScript monorepo running Node/Express with a React frontend and GraphQL/Apollo API layer.
• Source control via GitHub.

Preferred Skills and Background

• Experience building internal platforms / developer tooling.
• Strong TypeScript skills and API design taste.
• Deep AWS experience across compute, networking, storage, and security.
• Strong Terraform and/or Pulumi proficiency.
• Experience designing and operating CI/CD systems.
• Track record building production observability stacks.
• Experience building “paved roads” that bake in secure, reliable defaults.
• Security-first mindset.
• Aurora PostgreSQL operations at scale.
• Comfort with Docker and container orchestration environments.
• Reliability engineering mindset.
• Curiosity about the unique infrastructure demands of AI and LLM workloads.
• Strong written communication skills.

Perks & Benefits

• Robust medical coverage (100% of employee + family premiums covered).
• Vision & dental coverage.
• 401(k).
• HSA / FSA.
• Access to lender partner’s employee loan program.
• Remote-first culture - work from wherever you do your best work.
• Flexible time off - we trust you to manage your time.
