Descripción del empleo

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Product Engineer based in Spain.

Join a fast-growing AI environment where you’ll have genuine ownership over a product used by more than 2 million registered users. You’ll work directly with the founder to shape what gets built, how it looks and feels, and how it reaches users from idea through release. The role combines frontend craftsmanship with backend engineering, giving you influence across the full product experience. You’ll help evolve an AI-powered platform that transforms images and text into ready-to-use 3D models and supports increasingly sophisticated business workflows. With a high degree of autonomy and minimal bureaucracy, you’ll be encouraged to identify opportunities, make decisions, and move ideas into production. Strong engineering and product instincts matter most, with support available as you develop your understanding of the 3D domain.

Accountabilities

• Own product features from initial idea through design, implementation, and release, taking initiative rather than relying on detailed specifications.
• Build polished, intuitive, and refined user interfaces using Next.js, representing approximately 60% of the role.
• Develop and maintain backend functionality using Django and PostgreSQL, representing approximately 40% of the role.
• Integrate third-party AI model APIs and help turn emerging AI capabilities into practical product experiences.
• Maintain and improve servers and platform reliability while handling significant volumes of user data.
• Maintain a consistently high standard of UX and UI quality, paying attention to details such as interactions, animations, visual polish, and overall usability.
• Learn and contribute to the product’s 3D workflows, including how models, formats, and pipelines work.
• Proactively identify opportunities for new features and improvements based on user needs and product potential.
• Use AI-powered coding tools as part of your daily workflow to increase productivity while maintaining engineering quality.

Requirements

• 5+ years of full-stack engineering experience building and shipping web products across frontend and backend.
• Strong hands-on experience with Next.js for frontend development and Django with PostgreSQL for backend development.
• Practical experience managing servers and working with Linux environments.
• Strong product sense, with an appreciation for clean UX/UI, usability, and the small details that create a polished product experience.
• Demonstrated ownership of products used by real customers, ideally gained in a startup, as a founder, or through meaningful personal or side projects.
• Ability to work independently, make product and technical decisions, and proactively drive initiatives from concept to completion.
• Strong AI literacy and a willingness to use AI tools to improve productivity, engineering quality, and day-to-day workflows.
• Curiosity about emerging technologies and the ability to identify practical opportunities to apply them.
• Experience with 3D models or the broader 3D ecosystem is a plus, including meshes, formats, Blender, or headless/pipeline workflows.
• Additional experience with product scaling, serverless GPU platforms such as Modal, Neon, Celery, or third-party AI model APIs is advantageous.
• Strong communication, collaboration, and problem-solving skills, with an interest in working within a supportive and highly autonomous environment.
• 3D experience is not required; strong product and engineering fundamentals are the priority, with opportunities to develop 3D expertise on the job.

Benefits

• 100% remote work with the flexibility to work from wherever you are.
• High autonomy and a high-trust working environment where you can choose how to approach problems and solutions.
• Minimal bureaucracy, unnecessary meetings, and red tape, allowing the team to maintain momentum.
• Opportunity to work closely with the founder and have direct influence over product direction.
• Small, friendly, and collaborative team environment.
• Access to a broader entrepreneurial SaaS professional network for exchanging knowledge, ideas, and expertise.
• Opportunity to contribute to the growth of an AI-powered product with a large and expanding global user base.
• Location-adjusted compensation targeting local market medians for a remote-first environment; the salary range is shared in writing before the first interview.
• Commitment to diversity, inclusion, and equal opportunity.
