Technical Cofounder

Company Description Cotervia is building sustainability into everyday systems so that responsible choices become the default rather than relying on perfect individual behavior. The organization is rethinking how recycling works by addressing confusing rules, inconsistent infrastructure, and the lack of meaningful feedback for users. By redesigning materials, incentives, and daily interactions, Cotervia aims to make sustainable choices simpler, clearer, and more rewarding. The team works at the intersection of design, technology, and policy to create practical solutions that can scale in real-world environments. Role Description As a Technical Co-founder at Cotervia, you will help shape the product vision and build the technical foundation for solutions that improve recycling and sustainable behavior. This part-time remote role involves designing and developing early prototypes, selecting and implementing core technologies, and iterating quickly based on user feedback and pilot results. You will collaborate closely with non-technical co-founders to translate system-level sustainability concepts into actionable product requirements and technical roadmaps. Day-to-day, you may work on data models, APIs, and user-facing tools; evaluate technical feasibility of new ideas; and set coding standards, architecture patterns, and security best practices. You will also contribute to fundraising discussions, technical due diligence for partnerships, and long-term scaling plans. Qualifications

• Strong software engineering skills, with experience in building and shipping web or mobile applications (e.g., full-stack development, API design, databases).
• Ability to design technical architectures for early-stage products, including system design, scalability considerations, and integration with third-party services.
• Comfort with rapid prototyping, experimentation, and working with incomplete information in a startup environment.
• Experience or strong interest in sustainability, circular economy, or climate-related technology, and willingness to learn domain-specific concepts.
• Collaborative mindset, clear communication skills, and ability to work effectively with non-technical team members and external partners.
• Ability to commit part-time hours consistently and work remotely across time zones, with a high degree of autonomy and accountability.
• Previous startup, founding, or early-stage product experience is highly beneficial; familiarity with data analytics or behavioral design is a plus.
• No specific degree requirements; relevant experience, portfolio, or demonstrable projects are valued.
