• Robust understanding of web standards, infrastructure (databases, storage, caching, content delivery, etc.), and cloud platform offerings.
• Effectively communicate and collaborate with users and business stakeholders, facilitating software and process requirements.
• Experience leveraging debugging expertise and a proven track record of independently solving problems.
• Solid understanding of SQL and relational databases.
• Familiarity with version control systems like Git, CI/CD pipelines for automated testing & deployment, and infrastructure tools like Terraform.
• Understanding of cutting edge AI tools and a commitment to leveraging them to rapidly deliver high quality software.
• Ownership mentality and initiative to make improvements to code, processes, and user experiences across the organization.
• Commitment to Nexamp's mission and have a passion for solving tomorrow's climate crisis today.
• Demonstrated experience in effectively communicating information, ideas, and perspectives with people inside and beyond your organization.
• Experience in showcasing initiative to make improvements to current work, processes, products, and services across the organization. We value accountability and an ownership mentality.
• Ability to ask appropriate questions, analyze data, identify the root causes of problems, and present creative solutions.
• Expertise in building strong internal and external relationships with customers and stakeholders, instilling trust and loyalty across the industry.
