LLM Application Developer

agentic AI platform

LLM Application Developer

What you'll do:

• Design and implement prompt engineering systems, evaluation frameworks, and LLM performance monitoring for production agent deployments
• Develop and maintain our agentic SDK that powers multi-agent orchestration and tool-calling capabilities across enterprise systems
• Build LLM operations infrastructure including model serving, version control, A/B testing, and performance optimization pipelines
• Create comprehensive testing and evaluation suites to ensure agent reliability and measure model performance against business KPIs
• Work closely with the innovation team to integrate new model capabilities and optimize agent behavior for customer use cases

What we're looking for:

• 3–5 years of software engineering experience with strong Python proficiency, asynchronous programming (Async IO), and API development skills
• Hands-on experience building, productionising and maintaining LLM applications including RAG systems, prompt engineering frameworks, evaluation pipelines and preferably, agentic systems.
• Strong understanding of LLM software development patterns, multi-agent orchestration, and tool-calling frameworks
• Experience with LLM operations - model serving, monitoring, version control, and performance optimization
• Familiarity with evaluation methodologies, A/B testing, and metrics collection for ML systems in production
• Bonus: experience with agentic frameworks (LangChain, Semantic Kernel, CrewAI, AutoGen), MLOps tools, enterprise system integrations

Benefits

• A core engineering role in a fast-scaling Industrial-AI startup with operations in Singapore and Germany.
• End-to-end ownership of LLM application development — from prompt engineering to production monitoring — with direct impact on real-world, mission-critical enterprise workflows.
• Opportunities to work at the intersection of agentic AI, enterprise integrations, and large-scale production systems, shaping the capabilities of our next-generation Agentic SDK.
• Collaboration with a deeply technical founding team and innovation specialists to integrate cutting-edge model capabilities and deploy them in high-value customer environments.
