Product Engineer (Full‑stack)

About the role

Sparengine is building an AI‑powered aviation technical‑records platform. As a Product Engineer you will own the client‑facing surface where users upload data, view analysis results, and interact with deliverable visualisations. The role is execution‑heavy, requiring you to ship features from concept to a live URL.

Key responsibilities

• Design and implement the upload and analysis flow with real‑time progress indicators.
• Create clear deliverable views such as component status, event trace, and work‑package completeness.
• Integrate front‑end components with back‑end pipeline outputs.
• Ensure quality by testing features on real cases before release.
• Deploy production‑ready code and maintain scalability.

Required profile

• Full‑stack autonomy – ability to work across the entire stack independently.
• Proven track record of shipping functional applications beyond tutorials.
• Technical maturity to simplify requirements and keep code clean.
• Portfolio or GitHub showing end‑to‑end features you have delivered.

Required skills

• Next.js
• Strong full‑stack fundamentals and clean state handling.
• Experience taking a feature from a blank page to a live URL.
• QA discipline – confirm tests before marking tasks complete.

What we offer

• Fast iteration and real ownership of the user‑facing product.
• Opportunity to work remotely or from our Toulouse office.
• Full‑time or strong internship contract, compensation based on profile.
• Impactful work in an AI‑driven aviation tech environment.
