Senior Software Engineer, Basis

• Ownership. You run with autonomy and own what you ship — quality, reliability, and what happens after it hits production. You're at home driving projects from first sketch to launch and beyond
• Relentless Curiosity. You close your own gaps in knowledge, skill, and domain — and that depth shows up in planning, where you catch risks early and keep the technical path aligned with the business goals
• Leadership. You lead projects end-to-end across our stack, set the bar for quality, and pull other engineers up with you
• Collaboration. You demonstrate strong partnerships and communication skills through pull requests, demos, and working relationships
• Positivity. You bring a sense of strategic optimism and a solution-oriented mindset to work, while embodying Basis' core principles
• 5+ years professional software development experience
• Proven experience designing, building, and scaling modern, production‑level front‑end experiences using React, with supporting back‑end work in Ruby on Rails
• Current with modern development practices, including AI-assisted and agentic workflows for code generation, debugging, exploring, and documentation
• Strong grasp of data modeling and system design
• Enthusiastic growth-oriented mindset
• Don’t have every skill listed? No problem! We know experience can be built in many ways. If you have relevant skills that aren't reflected in your resume, we encourage you to share them in an optional cover letter
