[Hiring] Senior Technical Engineer @Voltility

Role Description

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.

• 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.
• Your work directly shapes what makes Voltility different.
• Have real ownership of the architecture as the platform grows.
• Help develop junior engineers along the way.

Qualifications

• 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.

Requirements

• 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.
