What was your reasoning?Have you ever worked on a project where you were responsible for everything, architecture, frontend, backend, infra and deployment? How did you manage?Tell me about an enterprise-grade application you built from scratch end-to-end—what did you personally own (architecture, infrastructure, and production release), and what exactly shipped?Describe a GenAI / agentic AI solution you built hands-on (multi-agent orchestration and/or RAG): what were the main components, how did data flow through the system, and what went live in production?Which AI coding tools do you use daily (e.g., Copilot, Claude Code, Code Assist), and give 2–3 concrete examples of how you use them in your day-to-day development workflow?JOB SUMMARYWe are seeking a senior full stack developer who is a hands-on builder with deep knowledge of GenAI and agentic AI. This person will own the full lifecycle of enterprise-grade applications—from translating business requirements into scalable architectures, to standing up proof-of-concepts, to delivering production-ready code. The role requires operating effectively in a large enterprise environment with strong familiarity around security frameworks, platform integrations, and production readiness.CORE RESPONSIBILITIESRequirements to ArchitecturePartner directly with business stakeholders to translate functional requirements into technical designs, system architectures, and data flow diagrams.Proof-of-Concept DevelopmentRapidly prototype solutions to validate feasibility, demonstrate value, and accelerate stakeholder buy-in.Full Stack DevelopmentOwn the end-to-end codebase: backend services, frontend interfaces, APIs, Terraform IaC, setup and deployment pipelines.Performance EngineeringDesign and optimize data-heavy applications that handle large-scale datasets with low latency and high reliability.Enterprise IntegrationBuild and maintain integrations across enterprise platforms including identity providers, internal APIs, and shared services operating at scale across multiple business lines.AI-Augmented DevelopmentLeverage GenAI-assisted coding tools and agentic frameworks to accelerate development velocity while maintaining code quality and best practices.Agentic AI Design and OrchestrationArchitect and build multi-agent systems, designing agent roles, tool integrations, orchestration patterns, and memory strategies using frameworks like Google ADK, LangGraph, or CrewAI to solve complex enterprise workflows autonomously.Enterprise Production Readiness KnowledgeNavigate enterprise production readiness processes, including KeyBank IT/application standards, submitting/managing ServiceNow change records (CRs), and coordinating across infrastructure, security, and platform teams to deploy to production.REQUIRED TECHNICAL SKILLSLanguages / FrameworksPython (advanced): Flask, FastAPIJavaScript/TypeScript: React, Next.js (or similar modern frameworks)HTML5, CSS3, Tailwind CSS (or equivalent utility-first CSS frameworks)RESTful API designCloud / Infrastructure (GCP)Cloud Run, Cloud FunctionsBigQuery (large-scale analytics)Cloud SQL (PostgreSQL)Cloud StorageCloud IAM, VPC, networking fundamentalsGeminiGoogle ADKApigeeInfrastructure as Code / DevOpsTerraform for provisioning and managing cloud infrastructureGitLab (repos, branching strategies, CI/CD pipelines)Container orchestration, deployment automation, environment promotion workflowsData / PerformanceDesigning high-performance, data-intensive applicationsSQL proficiency across analytical and transactional databasesData pipeline design and optimizationCaching strategies, async processing, query tuningAI / GenAIStrong understanding of LLMs, prompt engineering, and RAGHands-on agentic AI frameworks: Google ADK, LangGraph, CrewAI (or equivalent)Multi-agent orchestration: designing, deploying, and managing systems with specialized agents collaboratingGenAI integration via Vertex AI, OpenAI APIs, or similar platformsAI-assisted development using tools like Google Code Assist, Claude Code, or GitHub CopilotStays current on evolving AI frameworks/patternsEnterprise OperationsActive Directory group management and RBAC patternsSSO and Okta integration for federated identityServiceNow: submitting change requests (CRs), service requests, coordinating approvals for production changesComfortable coordinating across cross-functional teams to drive deployments and resolve dependenciesFamiliar with enterprise change management, production governance, and release coordinationDESIRED EXPERIENCE7+ years of hands-on software development experience, including 5+ years in a full stack capacityDemonstrated history building and shipping enterprise-grade applications from scratch (not only maintaining existing systems)Experience in large financial institutions or similarly regulated industries (strong plus)Comfortable collaborating across cloud, networking, DevOps, infrastructure, security, data, and business teamsTrack record independently driving technical initiatives from concept through production
