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.
