You'll own a significant area of this platform end to end: shaping the design, writing the code, securing it, shipping it through CI/CD, and operating it in production. This is a true full-stack role - frontend and backend are equally important, and you're expected to be effective across both. You'll move comfortably between a React UI, the serverless APIs behind it, and the infrastructure that runs it all. This is a senior role for someone who can take an ambiguous problem, drive it to a well-architected solution, and deliver with minimal oversight. You'll set technical direction in your area, raise the quality bar, and mentor others - not wait to be handed tickets. Responsibilities * Own a domain end to end across the full stack - from the React UI through the serverless API to the data and infrastructure that backs it. * Build and maintain features in a React single-page application and a family of independently deployable micro-frontend widgets that embed into it. * Design and implement Python serverless APIs (AWS Lambda behind API Gateway), with typed request/response models and an OpenAPI contract as the source of truth. * Build and evolve identity and authorization - OAuth2/OIDC sign-in, MFA, token validation, and fine-grained, entitlement-based access control (including delegated/third-party access scenarios). * Integrate with upstream enterprise APIs: model their contracts defensively, handle partial/missing data gracefully, run calls concurrently, and keep changes backward-compatible. * Design data and caching layers (e.g., DynamoDB), manage secrets, and tune performance and reliability of your services. * Harden everything for a regulated, PII/PHI-sensitive environment - data masking, least-privilege access, secrets management, and secure handling of personal data by default. * Own your CI/CD: automated linting, type-checking, tests, security scans, and infrastructure changes through to production. * Define and evolve infrastructure as code, and participate in operational ownership of your services., Owns the design, implementation, and operation of third-party integrations, public APIs, SDKs, and internal connectors. Builds resilient event-driven systems using Node.js, TypeScript, PostgreSQL, Kafka, Redis, and Kubernetes. Responsibilities include system design, performance optimization, production incident response, legacy-code refactoring, API versioning, monitoring, technical leadership, mentoring, and cross-functional collaboration., Develop and maintain a full-stack web application and platform for fraud analysis. Build APIs and user interfaces, write automated tests, troubleshoot production issues, collaborate with product, design, data science, infrastructure, and solutions engineering teams, and participate in on-call support. Use React, Golang, Python, PostgreSQL, Docker, and AWS technologies to deliver reliable products and meet service-level requirements.
