Job description

We are building an AI-assisted engineering automation product for the built-environment sector. We are looking for a developer who enjoys turning engineering logic into clean, testable code and professional outputs. This role sits between software development and building-services engineering, and it suits someone who is equally comfortable with code and with electrical concepts.

• Logic Encoding: Encode engineering rules and calculations into a deterministic, well-tested rules engine.
• Technical Outputs: Generate professional technical outputs such as spreadsheets, PDF reports, and system diagrams from structured data.
• Interface Development: Build a simple web interface for users to review, edit, and approve system outputs.
• AI Integration: Integrate deterministic logic with AI components through clean, robust interfaces.
• Collaboration: Work closely with the technical lead in daily stand-ups and weekly demos.

• Python Proficiency: 5+ years of experience with Python, including FastAPI.
• Frontend Development: Experience with React, Next.js, or rapid UI frameworks such as Streamlit.
• Logic & Testing: Proven experience writing calculation or rule-based logic supported by comprehensive unit tests.
• Document Generation: Programmatic generation of Excel, PDF, and diagrams using tools like openpyxl, ReportLab, WeasyPrint, Graphviz, or SVG.
• Domain Knowledge: An understanding of electrical fundamentals (circuits, loads, and control systems) or a proven ability to master complex domain concepts quickly.
• Data Handling: Comfort working with LLM-generated structured data.
