Senior Technical Engineer

Voltility; Greater London; Sur place; GBP 90 000 - 130 000; Plein temps

Résumé du poste

Voltility seeks a Senior Technical Engineer to own the end-to-end data collection platform. You will build pipelines from public and licensed sources, apply AI and rules-based extraction, and ensure trusted, structured records at scale.

You will own architecture, guide junior engineers, and work with product teams to ensure data flows cleanly into the client-facing platform. Focus is on data engineering with a hands-on full-stack approach.

Qualifications

• Strong Python and SQL with production experience across data pipelines, APIs and cloud infra
• Experience with web scraping, document/PDF extraction and LLM-based data structuring
• Track record building data products/pipelines where data quality matters
• Ability to translate non-technical specs into build plans and explain trade-offs clearly
• Experience mentoring junior engineers and energy/data-heavy domains

Responsabilités

• Design, build and run the collection platform and architecture: ingestion, extraction, matching, QA flags and storage into the product database
• Work with research leadership to prioritise data points to automate, set quality thresholds and measure coverage and freshness
• Apply LLM-based extraction, scraping and APIs with verification so output is trusted or clearly flagged
• Build tooling for researchers to review, correct and approve machine-collected data and improve it from feedback
• Develop tooling to help squads find and track targets (change detection, alerts, entity matching)
• Own reliability, monitoring and cost of pipelines and fix issues
• Maintain clean, documented code and data models for others to work on
• Mentor and assign work to junior engineers
• Collaborate with product engineering so data flows into the client-facing platform

Description du poste

Company overview

Voltility is a market intelligence platform for the people building, powering and financing the energy transition and data centre power markets. We track battery storage and hybrid power projects across the US and Europe, and in 2026 launched data-centre power coverage.

Following new investment we're growing the team quickly, so this is a chance to join early and help shape the business at an exciting time.

Role overview

The Senior Technical Engineer builds the platform that powers Voltility's data. This is a hands-on, senior full-stack role with a focus on data engineering, and you'll own the collection platform end to end.

You'll build pipelines that pull from public and licensed sources and use AI and rules-based extraction to turn them into structured, trusted records at scale. Every hour your tooling saves goes into proprietary intelligence, so your work directly shapes what makes Voltility different. You'll have real ownership of the architecture as the platform grows, and help develop junior engineers along the way.

Key responsibilities

• Design, build and run the collection platform and architecture: ingestion, extraction, matching, QA flags and storage into the product database
• Work with research leadership to prioritise which data points to automate, agree quality thresholds and measure coverage, accuracy and freshness
• Apply predominantly LLM-based extraction, scraping and APIs appropriately, with verification steps so output can be trusted or clearly flagged
• Build the tooling researchers use to review, correct and approve machine-collected data, and iterate on it from their feedback
• Build the tooling that helps squads find and track proprietary collection targets (change detection, alerts, entity matching)
• Own reliability, monitoring and cost of the pipelines, and fix what breaks
• Maintain clean, documented code and data models that others can work on
• Mentor and set work for junior engineers
• Work with product engineering so collected data flows cleanly into the client-facing platform

Suggested experience

• Very strong developer with production experience in Python and SQL, comfortable across the stack (data pipelines, APIs, cloud infrastructure, light front-end tooling)
• Hands-on experience with web scraping, document and PDF extraction and LLM-based structuring of unstructured text, including the failure modes
• Experience building data products or pipelines where data quality was measured and mattered
• Able to turn a non-technical specification into a build plan and explain trade-offs in plain English
• Experience mentoring junior developers; interest in energy or a comparable document-heavy domain
• Adept with agentic coding harnesses Codex or Claude Code (or equivalent) - demonstrable knowledge on what it takes to build solutions rapidly & precisely using these toolkits
