Katalyst Data Management is seeking a Senior AI/ML Engineer to serve as a technical lead for segments of our AI innovation platform. This is a hands-on, high-impact role where you will own architecture and day-to-day development for AI projects that move from prototype to production.

You will work directly with the Director of Innovation and a small, high-velocity team to build, ship, and iterate AI capabilities that deliver real value to leading oil and gas clients worldwide. This is not a research-only role; it requires sound architectural judgment, practical execution, and the ability to deliver production-ready solutions in a rapidly evolving technology landscape.

The position may be based in Rio de Janeiro, Brazil; Houston, Texas; or Calgary, Alberta. We value adaptability and intellectual curiosity over mastery of any single technology stack, and we are especially interested in candidates who have repeatedly learned new tools quickly, made thoughtful technical decisions under uncertainty, and shipped AI/ML solutions that work in production.

Key Responsibilities:

• Operate, scale, and optimize production GPU environments supporting AI workloads, including inference/model serving, OCR and vision models, embeddings, and large-scale document ingestion.
• Lead the design and implementation of production AI/ML services that support intelligent search, classification, retrieval, and natural language interfaces for subsurface and E&P data.
• Own technical architecture for core platform components, including retrieval systems, orchestration, model serving, and data pipelines, while balancing reliability, cost, security, and delivery speed.
• Build, maintain, and optimize retrieval systems using relational databases, full-text search, and search or analytics platforms such as Elasticsearch/OpenSearch.
• Develop and maintain RAG-style pipelines, including embeddings, vector search, hybrid retrieval, reranking, grounding, and evaluation against real customer workflows.
• Integrate LLM APIs and agentic tooling into end-to-end applications, including prompt design, tool/function calling, evaluation, and production guardrails.
• Support deployment, observability, alerting, incident response, and CI/CD practices across on-premises and cloud environments.
• Partner with product leaders, business stakeholders, data experts, and domain specialists to translate ambiguous problems into clear technical plans, milestones, and measurable outcomes.
• Establish and uphold engineering standards for code review, testing, documentation, design reviews, and operational excellence.
• Mentor and provide technical guidance to engineers as the platform evolves.

Required Qualifications:

• Bachelor's degree in computer science, Engineering, Data Science, or a related field, or equivalent practical experience.
• 5+ years of professional software engineering experience, including 3+ years building and operating ML/AI-enabled applications in production.
• Demonstrated experience designing and supporting end-to-end services, including APIs, data pipelines, model integration, observability, deployment, and operations.
• Hands-on experience delivering search or information retrieval features, including full-text search, ranking/relevance, indexing strategy, and performance optimization.
• Experience working in cloud environments and shipping containerized services using CI/CD practices.
• Strong English communication skills, both oral and written, are required.

Skills Required:

• Strong programming skills in Python preferred and/or Node.js, including writing clean, testable code and reviewing others' code.
• Strong SQL and relational database experience, including advanced querying, schema design awareness, full-text search, and performance tuning.
• Experience with search and analytics platforms such as Elasticsearch/OpenSearch or equivalent.
• Practical experience integrating LLM APIs into applications, including prompting patterns, tool/function calling, basic evaluation, and production guardrails.
• Comfort working with modern AI development workflows, including agentic coding tools such as Claude Code or Codex to accelerate delivery while maintaining quality.
• Working knowledge of cloud services and security fundamentals, including IAM concepts, secrets management, and network boundaries.
• Strong English communication skills, both oral and written, with the ability to explain complex technical concepts clearly to technical and non-technical stakeholders.
• Ability to translate ambiguous business needs into clear technical plans, trade-offs, and deliverables.

Preferred Qualifications & Skills:

• Oil and gas industry experience or domain knowledge, including well data, seismic data, or regulatory documents.
• Experience with GPU-accelerated workloads and the NVIDIA ecosystem.
• Background in OCR pipelines and large-scale document processing.
• Familiarity with vision-language models for document understanding.
• Experience with agent-to-agent or multi-agent AI system patterns.
• Patent, publication, or conference presentation experience in ML/AI.

Work Environment:

This role is based in a professional office setting with routine use of computers and collaboration tools. Work is highly technical and team-oriented, involving close coordination with Cloud, Infrastructure, and Software Engineering teams. The environment emphasizes automation, scalability, and security, with frequent virtual meetings and occasional cross-functional project work.
