Note: The job is a remote job and is open to candidates in USA. Loancrate builds AI-native tooling to automate mortgage workflows and simplify home-buying for lenders and borrowers. The Senior Software Engineer - Platform will build and operate AWS infrastructure, internal developer tooling, CI/CD systems, observability, security, and scalable data-platform systems that enable product engineers to ship quickly and reliably.
Responsibilities
- Own and evolve our AWS infrastructure using Terraform and Pulumi Cloud - treating infrastructure as a product that engineering teams depend on
- Design and maintain internal developer tooling and libraries that standardize how we build and ship - code generation, shared SDKs, data access patterns, and service scaffolding
- Create and maintain golden paths for common workflows (new service setup, background jobs, event streams, APIs) so teams can ship quickly with built-in security and observability (and consistent defaults across services)
- Build and maintain CI/CD pipelines and per-PR ephemeral environments that make deploying feel easy and safe
- Drive reliability through SLOs, auto-scaling, incident response, and postmortems - and build systems that make the next incident less likely
- Create observability tooling and shared instrumentation libraries that give engineers real-time insight into their services
- Enforce security best practices across IAM, secrets management, encryption, audit logging, and DDoS protection
- Own the reliability and performance of our data platform (Aurora PostgreSQL) - provisioning, backups, failover, and tuning - and build tooling that makes safe usage the default
- Reduce toil through automation and self-service tooling so engineers can move fast without waiting on the platform
- Contribute to architecture decisions and documentation, and participate in on-call rotation (shared by the whole engineering team)
Skills
- • 🧩 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
