Requirements
- 7+ years of professional engineering experience
- English proficiency
- Familiarity with AI/LLM integration patterns: orchestration frameworks, MCP, output quality management, and prompt engineering
- You can take a vague brief, ask the right clarifying questions, form a plan, and deliver a working system without heavy supervision
- You've built real systems end-to-end before and can point to specific examples. Past experience with internal tools or automation platforms is a strong plus.
- Experience with access control design (RBAC, zero trust principles), data sensitivity considerations, and API gateway patterns

- Experience with service-oriented architecture, API gateway patterns, and inter-service communication (GraphQL, gRPC, or similar)
- You can communicate effectively with both technical and non-technical audiences and are comfortable leading presentations and deep-dive technical discussions
Responsibilities
- Design and build AI-powered tools and automations that streamline internal business processes (HR, Finance, etc.), working directly with stakeholders to identify opportunities
- Evaluate where LLM orchestration, chat interfaces, or multimodal AI genuinely adds value versus where standard software engineering is the right answer
- Design async processing pipelines, batch workflows, and decoupled service architectures suited to internal tooling at scale
- Oversee day-to-day engineering work, keeping the team unblocked and aligned on priorities
- Architect scalable backend systems using languages and frameworks such as Pythonand Java. Experience with Kotlin is a plus.
- Contribute to frontend work using React and TypeScript as needed
- Drive decision-making around performance, scalability, and system design
- Write clean, maintainable code and ensure engineering best practices are followed
