#HOT# Senior Systems Programmer / AI Engineer (Contract)

#HOT# Senior Systems Programmer / AI Engineer (Rolling Contract) Location: Singapore Type: 12-month contract, renewable Style: Hybrid, with a highly flexible arrangement Position Overview We are seeking an experienced Senior Systems Programmer / AI Engineer to take technical ownership of complex, business-critical systems within a global technology organization. This is a highly technical individual contributor role focused on AI-enabled engineering, large-scale software systems, evaluation infrastructure, system reliability and technical architecture . The successful candidate will be expected to independently own technically complex problem spaces, make high-impact architectural decisions, build and operate production systems, and drive new technologies from experimentation through to hardened production. Key Responsibilities • Own the architecture, development and operation of complex production systems with organisation-wide impact • Define technical strategy and make independent engineering decisions across ambiguous and technically challenging problem spaces • Design and build AI evaluation, validation and experimentation infrastructure to assess the reliability, quality and safety of AI-generated outputs • Develop and operate LLM, RAG, multi-agent or AI-assisted engineering systems in production environments • Establish measurable quality gates, monitoring, experimentation and validation frameworks before AI systems are deployed • Apply systems thinking across multiple services and engineering boundaries, identifying and resolving issues beyond direct ownership • Drive scalability, performance, reliability and fault tolerance across distributed systems • Evaluate emerging AI and software engineering techniques and take them from research or prototype through proof of concept and production • Establish engineering standards around security, data protection, AI safety and production reliability • Mentor senior engineers and help develop technical ownership and engineering judgment across the organization • Produce technical documentation and architecture specifications detailed enough for other engineering teams to consume systems independently Required Experience & Technical Skills • 10+ years of professional software engineering experience , including experience owning complex production systems • Demonstrated experience as a Senior Software Engineer, Staff Engineer or equivalent technical leadership position • Strong hands-on software engineering background with experience across backend, frontend, distributed systems or platform engineering • Proven production experience with AI/ML, LLM, NLP, RAG, fine-tuning or multi-agent systems • Practical experience designing AI evaluation, experimentation or validation frameworks , rather than only consuming third-party AI APIs • Strong understanding of distributed systems, system architecture, scalability, observability and fault tolerance • Strong programming capability in one or more of Python, PostgreSQL, Java, TypeScript or equivalent production languages • Experience with modern cloud and data platforms such as AWS or Azure , together with technologies such as Kafka, Spark, Flink, distributed databases or equivalent • Experience designing and operating production systems through the full software lifecycle, including development, testing, deployment, monitoring and incident resolution • Strong understanding of software security, data privacy and responsible AI principles • Proven ability to make technical decisions where requirements are ambiguous and the consequences of failure are significant • Experience mentoring engineers and influencing technical direction beyond an individual's immediate area of ownership Preferred Experience The following would be highly advantageous: • Experience building LLM evaluation or AI quality-assurance infrastructure • Experience with fine-tuning, RAG, agentic systems, model evaluation or AI safety • Experience developing AI-assisted engineering or autonomous software engineering systems • Experience with PyTorch, HuggingFace Transformers, LangChain, MCP or comparable AI framework • Experience with large-scale data processing using Kafka, Spark, Flink or MapReduce • Experience designing cloud-native systems using AWS and/or Azure • Experience taking emerging technologies from research or experimentation into hardened production environments • Experience leading technical initiatives involving multiple engineering teams What Makes This Role Different This is not a conventional Senior Software Engineer position. The successful candidate will be expected to own a technically difficult problem space end-to-end , rather than simply contribute code to an existing system. You will have significant responsibility for: AI Engineering × Distributed Systems × Technical Architecture × Evaluation Infrastructure × Production Reliability The role offers the opportunity to work on technically challenging systems where engineering judgment, experimentation and long-term technical ownership are critical.
