You will build the self-service systems, TypeScript libraries, deployment automation, and reliability foundations that let product engineers ship quickly and safely as the company scales.\nWhat you'll do\nOwn and evolve AWS infrastructure using Terraform and Pulumi across compute, networking, storage, security, and data services.\nDesign and maintain internal developer tooling, TypeScript libraries, shared SDKs, code generation, command-line tools, and reusable frameworks.\nBuild and optimize CI/CD pipelines in Buildkite and maintain per-pull-request ephemeral environments.\nImprove reliability through service-level objectives, error budgets, autoscaling, observability, and incident response.\nSolve performance and scale challenges across Aurora PostgreSQL, distributed services, and an AI-native mortgage platform.\nPartner with product engineers to make development, testing, and deployment fast, consistent, and safe.\nDocument complex systems clearly and raise the technical standard across the engineering organization.\nRequirements\nWhat we're looking for\nSeven or more years of software engineering experience, including substantial platform, infrastructure, or backend work.\nStrong experience at a high-growth technology startup.\nRecent hands-on experience building and maintaining CI/CD pipelines and per-pull-request environments, ideally with Buildkite.\nProficiency with TypeScript and Node.js, including the ability to navigate and make meaningful changes to a production codebase.\nDeep AWS experience across compute, networking, storage, security, and data services.\nStrong Terraform and/or Pulumi skills, including modules, workspaces, and CI-driven plan and apply workflows.\nExperience with service-level objectives, error budgets, incident response, and production observability.\nA track record of shipping production code, not solely administering infrastructure or coordinating other engineers.\nStrong written communication and the ability to document complex systems.\nBonus points\nHands-on Buildkite optimization experience.\nExperience building internal platforms, developer tooling, shared SDKs, code generation, or frameworks.\nExperience with Datadog, CloudWatch, Sentry, distributed tracing, or comparable observability systems.\nBenefits\nCompensation and benefits\n$150K-$350K base salary, depending on seniority and experience. Senior-level compensation may reach $300K base, while staff-level compensation may reach $350K base.\nCompetitive equity.\nMedical premiums covered at 100% for employees and their families, plus dental and vision coverage.\n401(k), HSA and FSA options, and flexible time off.\nThis role is not open to visa sponsorship or transfers. Candidates must already have unrestricted U.S. work authorization.\nLocation and work model\nThis is a full-time, remote role based in the United States.
