Technical Analyst / Senior Technical Analyst - Energy Transition

Climate17 are working with a leading, specialist energy transition advisory firm to appoint a Technical Analyst / Senior Technical Analyst into a high-impact, high-ownership role.

The Opportunity

This is a role for someone with a strong engineering foundation and a builder's mindset. You will work close to the commercial and consulting teams, translating real-world market questions into robust technical systems. The centre of gravity is Python engineering, data platform development, and modelling infrastructure, with a strong opportunity to shape how AI tools are embedded into consulting workflows. You will have meaningful autonomy and influence over technical architecture, standards, and tooling.

Key Responsibilities Build and Operate a Modern Data Platform

• Design and maintain data pipelines to ingest, validate, and publish curated datasets used in modelling and dashboards.
• Establish robust data quality, observability, monitoring, and documentation practices.
• Develop scalable database and storage architectures, including lake/lakehouse concepts (partitioning, schema evolution, versioning, governance).
• Apply strong SQL and data modelling principles to support performance and reliability.

Strengthen the Energy Modelling Environment

• Develop reusable Python packages and services supporting market scenario modelling and investment workflows.
• Improve reproducibility and reliability of modelling runs (configuration management, structured logging, versioned scenarios).
• Raise engineering standards across testing, code review, CI/CD, and maintainable architecture.

Implement Scalable AI Solutions (Agents RAG)

• Prototype and productionise internal AI tools to support research, drafting, document extraction, synthesis, and knowledge search.
• Build end-to-end RAG systems including ingestion pipelines, embeddings, retrieval strategies, reranking, evaluation frameworks, and monitoring.
• Ensure safe-by-design implementation, with appropriate access controls, auditability, and data governance.

Desirable: Develop Lightweight UI Tools

• Create simple web applications and dashboards enabling analysts and clients to explore data and model outputs.
• Translate business requirements into intuitive user experiences backed by secure APIs.

Example Project Ownership

• Building a curated time-series lakehouse covering fundamentals, prices, and market curves with lineage and quality controls.
• Developing a scenario management system enabling versioned, reproducible market simulations.
• Deploying a permission-controlled RAG assistant across internal research, models, and deliverables.
• Supporting development of a client-facing data portal.
• Designing interactive dashboards to explore sensitivities and scenario comparisons.

Candidate Profile

• Quantitative degree (Engineering, Mathematics, Physics, Computer Science, Statistics or similar).
• 3 years' experience building production-grade software or data systems.
• Strong Python engineering capability beyond notebook environments.
• Strong SQL and data modelling expertise.
• Ability to take ownership of ambiguous problems and deliver structured, production-ready solutions.
• Clear communication and documentation skills.
• Rapid learner, comfortable working across evolving technologies.

Advantageous

• Experience with data platforms and database architecture.
• UI development experience (React JavaScript/TypeScript or similar).
• AI engineering exposure.
• Experience building RAG systems and working with vector databases.
• Docker, CI/CD, deployment practices and secrets management.
• Energy markets exposure (not essential; sector knowledge can be developed).

Why This Role?

• Work on tools that directly inform high-stakes investment decisions.
• Operate in a technically ambitious but commercially grounded environment.
• High autonomy and scope to shape architecture and engineering standards.
• Meaningful exposure to European energy transition dynamics.
