Within your first month, you'll be diving into mission-critical work such as... * Designing and building the systems that let engineers deploy dozens of times per day with confidence - from our Buildkite CI/CD pipelines and per-PR ephemeral environments to our IaC-managed AWS infrastructure. * Creating self-serve developer experiences - local dev tooling, templates, golden paths, and CI-integrated workflows - so "the right thing" is the easy thing. * Pioneer tooling and best practices for AI-first software engineering - from setting up background agents to autonomously make code changes to designing frameworks that allow AI product experiences to self-optimize in response to user interactions. * Extending our internal TypeScript tooling - from schema/code generation to data access libraries - so teams can build features faster with safer, more consistent primitives. * Making Loancrate's platform observable and self-healing - instrumenting our services with Datadog, building alerting that actually signals rather than spams, and reducing the blast radius of incidents before they happen. * Baking security into our platform defaults - across infra and developer tooling - while keeping engineering velocity high. * Solving interesting scaling problems as our AI-native mortgage platform grows - from Aurora PostgreSQL tuning to Kafka throughput to cost-efficient compute autoscaling. Core 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). ## Related Videos - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) - [Why segmenting your infrastructure into tiers makes your infrastructure design better](https://www.wearedevelopers.com/videos/1960-why-segmenting-your-infrastructure-into-tiers-makes-your-infrastructure-design-better) - [From Doubt to Confidence: How Sentry Uses Verdaccio to Bulletproof SDK Releases](https://www.wearedevelopers.com/videos/739-from-doubt-to-confidence-how-sentry-uses-verdaccio-to-bulletproof-sdk-releases) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Unleashing Potential Across Teams: The Power of Infrastructure as Code](https://www.wearedevelopers.com/videos/930-unleashing-potential-across-teams-the-power-of-infrastructure-as-code) - [Inside Bitpanda's Tech Stack: Scaling a European Fintech Leader - Markus Dorner](https://www.wearedevelopers.com/videos/1979-inside-bitpanda-s-tech-stack-scaling-a-european-fintech-leader-markus-dorner) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift)
