Job Description

Role Mission

The Senior AI Engineer is a key contributor to our growing AI engineering practice, responsible for designing, delivering, and scaling intelligent systems that drive real business outcomes. In this role, you will architect production-grade AI solutions  spanning agentic workflows, retrieval-augmented pipelines, and LLM-integrated applications  that enable enterprise automation at scale. You bring both deep technical depth and a strong sense of delivery ownership, operating across the full stack to take AI initiatives from whiteboard to production with precision and speed.

Key Responsibilities & Skills

• Strong grasp of Generative AI fundamentals and how they differ from conventional software development, particularly when solving open-ended or creative problems
• Practical experience working with Large Language Models (LLMs), including navigating API cost trade-offs and managing unpredictable model behaviours in production
• Proficiency in prompt engineering techniques  including multi-shot prompting, persona and tone setting, and structuring effective context and constraints
• Solid full-stack or backend development background with advanced Python skills, including concurrency, async patterns, and performance-aware design
• Demonstrated ability to optimize AI workflows through systematic benchmarking, bottleneck analysis, and decomposing complex LLM call chains into efficient, maintainable components
• Practical judgment on when agentic architectures are appropriate  including an honest assessment of their complexity, failure modes, and operational overhead
• Experience enforcing structured LLM outputs and building reliable pipelines using orchestration frameworks such as LangChain or LangGraph
• Expertise in Retrieval-Augmented Generation (RAG): grounding model responses in authoritative knowledge bases and surfacing cited, verifiable claims
• Skilled in implementing input/output guardrails to defend against prompt injection, hallucinations, and harmful or policy-violating content

Soft Skills & Experience

• Sharp analytical and problem-solving mindset with the ability to work through ambiguity
• Clear, confident communicator  able to translate complex AI concepts for both technical peers and non-technical stakeholders
• Comfortable operating in fast-moving environments and adapting quickly as the AI landscape evolves
• 3–7+ years of hands-on experience in software, AI, or ML engineering with a track record of shipping production-grade systems
• Familiarity with cloud platforms (AWS, Azure, GCP) and modern DevOps tooling including Docker, Kubernetes, and CI/CD pipelines
• Proven ability to lead technical workstreams, mentor junior engineers, and translate ambiguous business needs into well-scoped engineering solutions.
