At this level, we expect you to own more than your ticket. That means thinking about design before writing code, building tests that give you and your team genuine confidence, monitoring production after you ship, and making the engineers around you better. You are not just a contributor; you are a force multiplier. Prior Ruby on Rails experience in production Experience with Sidekiq, Redis, and background job architecture Familiarity with AWS services (RDS, SQS, S3, ECS) and Terraform Experience with feature flagging systems (Flipper) and progressive rollout strategies Real estate, proptech, or high-volume B2B SaaS domain experience Experience with API integrations across diverse payload formats (XML feeds, CRM integrations, vendor APIs) Rails internals: Deep understanding of ActiveRecord, complex background job processing (Sidekiq), RESTful API design, and modular architectural patterns including service objects and Rails engines. Strong candidates with experience in comparable frameworks (Python/Django, Elixir/Phoenix) who can ramp up on Rails quickly are equally welcome. Database expertise: Query optimisation, complex joins and views, indexing strategies, query plan analysis, schema and data migration strategies; working knowledge of constraints, triggers, and stored procedures Security: Rails and web security best practices including OWASP Top 10, data protection, user authentication and authorisation patterns Testing: Comprehensive test coverage across unit, integration, and end-to-end layers using RSpec and Cypress; writes tests that build confidence, not just coverage Observability: Structured logging, error handling, and APM tooling (NewRelic or equivalent); knows how to read what's happening in production Frontend (primary): Deep, production-proven experience with React including hooks, Context API, and state management patterns; TypeScript for type-safe development; performance optimisations including memoization, lazy loading, and code splitting Infrastructure: Comfortable with AWS services, CI/CD pipelines with automated testing and deployment, Terraform basics, and secrets management best practices.", "stars": 0.0, "medallionProgram": null, "location_flexibility": null, "work_location_option": "onsite", "canonicalPositionUrl": "https://costar.eightfold.ai/careers/job/446719527960", "isPrivate": false}], "isFallback": true, "debug": {}, "count": 1, "personal_message": "We thought you would be interested in this position.", "scheduling": {"minTime": 9, "limit": 10, "maxTime": 17, "increments": 60, "minTimeslots": 3}, "userTitles": [], "enableTargetedResume": false, "query": {"query": "", "location": "", "department": [], "skill": [], "seniority": [], "pid": "446719527960"}, "singleview": true, "see_all_jobs": true, "recommended_star_threshold": 4.0, "chatbot": true, "iframeImplementation": null, "pcsApplyFormV2Enabled": true, "allowedFileTypes": {}, "pcsTextConfiguration": {}, "hideDepartment": true, "pcsOctupleMigration0Enabled": true, "pcsOctupleMigration1Enabled": false, "replaceUrlOnGoBack": true, "isEuAiActLabellingEnabled": false, "pcsRedesignedNuxEnabled": true, "readmoreInstructionEnabled": false, "userActivityTimeout": 86400000, "userActivityTimeoutEnabled": 1, "isLoggedInPcsEnabled": false, "sortByConfig": [{"id": "relevance", "label": "Relevance"}, {"id": "new", "label": "New to Old", "value": "if(field(position.ats_data.creation_ts, max), field(position.ats_data.creation_ts, max), field(position.timestamp, max)) desc"}, {"id": "old", "label": "Old to New", "value": "if(field(position.ats_data.creation_ts, max), field(position.ats_data.creation_ts, max), field(position.timestamp, max)) asc"}], "searchBoxConfig": {}, "excludePrivatePositions": true, "eeocFilterKeywords": ["veteran", "disability", "gender", "race", "citizen", "visa", "ethnicity"], "disableScrollLoadPositionSidebar": false, "locationFlexibilityFrontendEnabled": false, "workLocationOptionFrontendEnabled": true, "remoteFlexibleJobsFilterEnabled": false, "loggedOutNotificationsEnabled": true, "candidateLogin": {"postApplyReviewLink": {"enabled": true, "url": "/api/apply/v2/profile/review/initialize_user?domain=costar.com", "title": "What's next?
