Software Engineer

• As a Software Engineer at Blend, you will design, implement, and maintain the platform that powers 20% of mortgages in the US. You’ll work closely with our product development team to translate customer needs into functional, scalable software — and you’ll do it the modern way: with AI coding agents woven into every stage of your development lifecycle. We’re an engineering organization that builds AI-first
• Build features end-to-end across the stack — from responsive, accessible user interfaces to resilient, scalable back-end services
• Use AI coding agents such as Claude Code, Cursor, or Codex daily across the software development lifecycle: planning, design, codebase analysis, implementation, testing, documentation, code review, and refactoring
• Apply and help evolve our AI-driven development lifecycle (AIDLC) practices — spec-driven development, agentic workflows, and effective context and prompt engineering — and share what you learn with the team
• Review, test, and harden AI-generated code to production quality. You own everything you ship, no matter who (or what) wrote the first draft
• Collaborate with cross-functional teams to translate business requirements into technical specifications and code
• Work with product managers and UI/UX designers to implement new features and enhancements with a seamless, accessible user experience across devices
• Design and develop applications that scale, with maintenance, resiliency, and robustness in mind
• Identify and troubleshoot software defects and issues, ensuring timely resolution
• Participate in code reviews to maintain code quality — including thoughtful review of AI-assisted contributions — and offer peer mentorship and guidance
• Participate in the team’s on-call rotation
• Create your own story! Some of Blend’s best features have come from engineering initiatives. You’ll have an opportunity to propose new ideas and build features end-to-end

• You’re hungry to learn. You have high learning velocity, you’re curious about new tools and techniques, and you treat a fast-changing toolchain as an opportunity rather than a burden
• You’re an excellent communicator who can operate independently and collaboratively in a fast-paced environment, driving projects to a successful outcome
• You’re a full-stack developer: comfortable in back-end development with languages such as Node.js, TypeScript, or Golang, and in front-end technologies such as HTML, CSS, JavaScript, and modern frameworks like React
• You use AI to write code every day. Tools like Claude Code, Cursor, or Codex aren’t experiments for you — they’re core to how you work, and you stay current as they evolve
• You have a Bachelor’s degree in Computer Science, Engineering, or a related field (or equivalent practical experience) with 2-5 years of experience building production software
• You’re proficient in the latest AIDLC techniques: decomposing problems into well-scoped tasks an agent can execute, writing effective specs and prompts, managing context, and critically evaluating AI output for correctness, security, and maintainability
• You have experience working with databases like Postgres, MongoDB, or similar technologies
