Office location: Vilnius (hybrid format, office visit 1-2 times a week)

About the role: 
We are looking for a Full Stack Engineer to join the CTO Office and take ownership of our client’s product development lifecycle. You'll work hand-in-hand with the CTO Office team, taking initiatives that have been validated as POCs and leading them into production-grade, scalable solutions.

Responsibilities:
- Take validated POCs from the CTO Office and architect, build, and ship them as production-ready applications
- Design and develop full-stack solutions — modern frontends paired with robust, scalable backends
- Build and deploy within the AWS ecosystem (Lambda, ECS/EKS, DynamoDB, S3, RDS, API Gateway, CDK/CloudFormation, and more)
- Own the CI/CD pipeline — design, build, and maintain automated workflows using GitHub Actions
- Design and build internal agentic AI solutions using LangChain and LangGraph — from multi-step agent orchestration to RAG pipelines and tool-augmented workflows
- Leverage Agentic IDE tools (Cursor, Claude Code, and similar) as a core part of your development workflow, applying best practices around skills, MCPs, agents, and prompt engineering to accelerate delivery
- Collaborate closely with the CTO Office, product stakeholders, sales, and pre-sales teams to translate business needs into elegant technical solutions 
- Make pragmatic technology decisions that balance speed, quality, and maintainability

Requirements:
Must-Have:
- 5+ years of professional full-stack development experience
- Frontend: Strong proficiency with Vue.js or React (with modern tooling such as Nuxt/Next.js, TypeScript, Vite, Tailwind CSS)
- A builder's mindset — you thrive on taking something from prototype to production
- Understanding of system design principles — you can architect scalable, reliable distributed systems and make sound trade-offs
- Grasp of data structures and design patterns — to work alongside your Agentic IDE you write efficient, well-structured code
- Backend: Solid experience with Python and modern frameworks — primarily FastAPI, or Django/Flask
- Hands-on experience with the AWS cloud ecosystem — you've built and deployed real workloads on AWS
- Hands-on experience building agentic AI systems with LangChain and LangGraph — including multi-agent orchestration, tool use, and RAG patterns
- Proven experience designing and maintaining CI/CD pipelines with GitHub Actions including automated PR based Code Reviews.
- Working knowledge of Agentic IDEs and AI-assisted development (Cursor, Claude Code, Windsurf, or similar) — including familiarity with skills, MCP servers, agents, and AI-driven development best practices
- Strong understanding of RESTful API design, relational and NoSQL databases, and cloud-native architecture patterns

Nice-to-Have:
- Experience with Amazon Bedrock and/or Azure AI Foundry for building and deploying AI/ML solutions on managed cloud platforms
- Experience with Infrastructure as Code (AWS CDK, Terraform, CloudFormation)
- Experience in security infrastructure (IDP, authentication protocols - S) and writing secured applications 
- Security & Identity - understanding of application security, including SSL/TLS certificates, secret management, and identity providers (IDP). Experience implementing authentication and authorization protocols such as SAML, OAuth2, and JWT.
- Foundational SRE knowledge, including monitoring, logging, and observability (e.g., CloudWatch, Prometheus, ELK) to ensure production stability and performance.
- Familiarity with FinOps concepts, cloud cost management, or multi-cloud environments
- Experience building data-driven tools — predictive models, analytics dashboards, or recommendation engines
- Exposure to Azure services alongside AWS
- Experience with containerization and orchestration (Docker, Kubernetes)
- Background in B2B SaaS or enterprise software development
