You will take ownership of solutions end-to-end: from understanding business needs and shaping requirements to architecture, full-stack development, cloud deployment, production support, and continuous improvement. The role combines modern full-stack engineering, Python backend development, cloud-native architecture, and applied AI. You will build web applications, APIs, integrations, automation workflows, and agentic AI systems using technologies such as LangChain and LangGraph. You will work closely with the CTO Office, FinOps, Operations, Sales, and Pre-Sales teams to turn loosely defined ideas into practical products that automate manual work and deliver measurable operational value. Initial initiatives may include FinOps automation, enterprise AI enablement, meeting assistants, internal productivity tools, and other AI-powered platforms. This is an end-to-end engineering role with a high degree of ownership. You will be expected to make pragmatic technical decisions, work independently, and operate solutions in production without relying on dedicated QA, DevOps, or SRE support for everyday delivery. Technical Stack + Languages & Frameworks: Python (FastAPI, Django, Flask), TypeScript, Vue.js, React, Nuxt.js, Next.js, Vite, Tailwind CSS + AI & Agentic Frameworks: LangChain, LangGraph, RAG, Multi-agent Orchestration, LLM Tool/Function Calling, MCP Servers, AI Skills + Cloud & Serverless: AWS (Lambda, ECS/EKS, DynamoDB, S3, RDS, API Gateway), Amazon Bedrock, Azure AI Foundry + Data & Architecture: REST APIs, Relational (PostgreSQL, MySQL) and NoSQL Databases + IaC & DevOps: GitHub Actions (Automated AI-assisted PR reviews), AWS CDK, Terraform, CloudFormation, Docker, Kubernetes + Observability & Operations: CloudWatch, Prometheus, ELK Stack + Security & Auth: OAuth 2.0, SAML, JWT, SSL/TLS, Secret Management + Agentic Dev Tools: Cursor, Claude Code, Windsurf. As a qualified expert, You will: + Turn Concepts into Reality: Transform CTO Office proofs of concept, scripts, and experimental solutions into scalable, production-ready applications. + Drive Full Product Lifecycle: Own projects end-to-end - from initial discovery and system architecture to deployment, ongoing support, and iterative improvements. + Bridge Tech and Business: Collaborate directly with the CTO Office, FinOps, operations, sales, and pre-sales stakeholders to translate loosely defined business needs into concrete technical designs. + Architect Modern Platforms: Build responsive frontends, robust Python backends, APIs, system integrations, and automated workflows using AWS serverless and containerized services. + Engineer Advanced AI Workflows: Build agentic systems using LangChain and LangGraph, covering RAG, tool calling, multi-agent orchestration, custom MCP servers, and reusable internal AI capabilities. + Ensure Operational Excellence: Establish CI/CD pipelines with GitHub Actions, write infrastructure as code, implement automated testing, and set up comprehensive logging, monitoring (CloudWatch/ELK), and failure recovery. + Enforce Production Security: Securely manage authentication (OAuth 2.0/SAML/JWT), secret storage, certificates, and strict access controls. + Set Engineering Standards: Define pragmatic development guidelines for the CTO Office function, document systems clearly, and transparently communicate risks and trade-offs. ## Related Videos - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [Leveraging Real time data in FSIs](https://www.wearedevelopers.com/videos/806-leveraging-real-time-data-in-fsis) - [MySQL Protocol Features You Should Be Aware Of](https://www.wearedevelopers.com/videos/100267-mysql-protocol-features-you-should-be-aware-of) - [Delay the AI Overlords: How OAuth and OpenFGA Can Keep Your AI Agents from Going Rogue](https://www.wearedevelopers.com/videos/1637-delay-the-ai-overlords-how-oauth-and-openfga-can-keep-your-ai-agents-from-going-rogue) - [NoSQL Data Modeling for Front-end Developers](https://www.wearedevelopers.com/videos/297-nosql-data-modeling-for-front-end-developers) ## Related Articles - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [From Prototype to Production: Build AI Agents with This Free 4-Course Learning Path](https://www.wearedevelopers.com/magazine/655-from-prototype-to-production-build-ai-agents-with-this-free-4-course-learning-path) - [Dev Digest 137 - AI'm not sure about this](https://www.wearedevelopers.com/magazine/485-dev-digest-137-ai-m-not-sure-about-this) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline)
