Product Engineer (Full-stack)
You own the surface where clients actually meet Sparengine: the upload and analysis flow, the deliverable views (component status, event trace, work package completeness), and the front-to-back integration with the pipeline. Next.js, clean state handling, real loading and progress states, and an instinct for trust-building UX. You ship fast, you QA on a real case before calling something done, and you confirm in one line what you tested.
Full-time / Strong intern, Remote or Toulouse, Product Engineer (Full-stack)
Company Overview
Sparengine is an AI-powered aviation technical records reconstruction and audit platform, built under Ascentis Technologies. Behind the pipeline sits a product that clients actually touch: upload, analysis, and the deliverable views that turn a knowledge graph into something a buyer can trust in minutes. We operate an international hybrid model with European direction and value shipping over ceremony.
The Role: Scope & Execution
You own the surface where clients meet Sparengine. This is an execution-heavy, ship-to-production role.
- Build the client-facing flow: the upload and analysis experience, with real loading and progress states and none of the trust-killing silence that breaks demos
- Build the deliverable views: component status, component event trace, and work package completeness, rendered clearly from structured data
- Integrate front to back: connect the interface cleanly to the pipeline outputs
- Own quality: ship features end-to-end, robust and scalable, and test on a real case before calling anything done
Technical Requirements
- Next.js and strong full-stack fundamentals
- Clean state handling and an instinct for trust-building UX in a high-stakes context
- Production deployment: comfortable taking a feature from blank page to live URL
- A QA discipline: one sentence confirming what you tested before marking a task complete
Professional Qualifications
- Full-stack autonomy: you navigate the whole stack independently
- Proven execution: functional applications you have built and shipped, beyond tutorials
- Technical maturity: you simplify requirements and keep code clean and reliable
- Evidence of work: a portfolio or GitHub of end-to-end features you have shipped
Practical Details
Location: Remote or Toulouse
Type: Full-time or strong intern
Compensation: Based on profile
Why Sparengine
The pipeline is only as valuable as the moment a client sees the result and believes it. You own that moment. Fast iteration, real ownership, and a product where good UX is the difference between a demo that closes and one that does not.
