You'll work closely with product, design, and our AI engineering team to bring new capabilities to life across the stack.\nResponsibilities:\nDesign, build, and ship features across the full stack from database schema and backend services to frontend UI.\nBuild and maintain RESTful APIs that power our web application and integrations.\nDevelop responsive, accessible, and performant user interfaces using modern frontend frameworks.\nCollaborate with product and design to turn requirements into technical specs and shippable increments.\nWrite clean, well-tested, maintainable code, and participate actively in code review.\nImprove application performance, reliability, and security across the stack.\nWork with our AI engineering team to integrate AI-powered features into user-facing product surfaces.\nContribute to architecture decisions, tooling, and engineering best practices as the team and product scale.\nMonitor, debug, and resolve production issues, and contribute to on-call rotations as needed.\nRequirements:\n5+ years of professional experience building full-stack web applications in production.\nStrong frontend skills: TypeScript and React, with experience building production-grade UIs.\nStrong backend skills: Python (FastAPI, Django, or similar), with experience designing and building APIs and services.\nPractical experience designing and working with relational databases (PostgreSQL, MySQL) and writing efficient queries.\nExperience building and consuming REST APIs.\nExperience integrating AI/LLM-powered features into a product by calling LLM APIs, working with retrieval-augmented generation (RAG) or vector search, or partnering with ML/AI teams to ship model-backed functionality.\nFamiliarity with cloud infrastructure (Azure, AWS, or GCP), CI/CD pipelines, and containerization (Docker).\nStrong understanding of software engineering fundamentals: testing, version control, code review, and system design.\nProficiency working with AI coding assistants (e. g., Claude Code, GitHub Copilot, Cursor) to accelerate development, while critically reviewing and validating AI-generated code.\nComfort working in a remote, async-first environment with strong written communication skills.\nNice to Have:\nFamiliarity with infrastructure-as-code (Terraform) and observability tooling (Datadog, Grafana, Sentry).\nFamiliarity with vector databases or embedding-based search for AI-powered features.\nBackground working in a startup or small, cross-functional team.\nExposure to design systems and component libraries.","description_format":"text","description_chars":2692,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Financial
