Senior Software Engineer

Bonterra is a company dedicated to enhancing the impact of nonprofits through technology. They are seeking a Senior Software Engineer to design and build reliable software features, collaborate with a mission-driven team, and leverage AI tools to drive client success.

Responsibilities:

• Design and build thoughtful, reliable features across the full stack. You'll work on backend services and APIs just as much as the frontend, and we need you to be strong at both
• Bring strong UI and UX sensibility to your frontend work. Good enough isn't good enough when clients are depending on it
• Proactively evaluate tradeoffs and speak up about them. We want someone who thinks about business value and client impact without needing to be asked
• Own your work from sprint planning and ticket refinement through implementation, peer review, and demo
• Use AI tools as a normal part of how you work, whether that's coding, debugging, or researching. This is table stakes for us
• Think critically about where AI can create real value for our clients and help shape features that deliver on that
• Partner closely with product managers, designers, and QA to ship things people actually want to use
• Give and receive code reviews in a way that makes everyone better, not just the code
• Share what you know. We grow together here

Requirements:

• 4+ years of full-stack JavaScript/TypeScript development on production systems
• Strong React experience including component architecture, state management, and performance
• Solid backend experience with Node.js and TypeScript, including building and maintaining production APIs and services
• Solid grasp of REST APIs and GraphQL on both sides of the wire
• Production experience with MySQL and/or PostgreSQL
• Familiarity with CI/CD practices using GitHub Actions, CircleCI, or similar
• Comfortable working in AWS or a comparable cloud environment
• Strong problem solving skills, high EQ, and the ability to communicate and collaborate well across a team
• Active daily use of AI coding assistants like Copilot, Cursor, or Claude. This is expected, not optional
• Hands-on experience building AI-powered product features, whether that's LLM integration, agentic workflows, or AI-assisted UX
• Mobile development experience as a nice to have
• Experience with Docker, Kubernetes, or infrastructure as code tools like Terraform or CloudFormation
• Familiarity with nonprofit or social impact technology
• Bachelor's degree in Computer Science
