About the role

You'll join Clarify as a Backend Engineer, building the foundational systems that power our AI-native CRM. You'll work directly with founders to architect critical infrastructure-from data pipelines and integration frameworks to developer tooling and system reliability. This is a role for someone who has built scalable platforms and is excited to establish best practices from the ground up with modern tooling and AI-first principles.
What you'll do

• Build core platform systems: data pipelines, integration framework, API infrastructure, and developer tooling.
• Design scalable data models and storage strategies for complex CRM workflows and AI capabilities.
• Establish observability, monitoring, and performance standards as we scale to thousands of customers.
• Create platform standards: API patterns, service design, testing frameworks, and deployment practices.
• Own critical technical decisions: infrastructure choices, architectural patterns, and technology selection.
• Partner with founders on technical strategy, balancing innovation with pragmatic execution.

• 6+ years building distributed systems and platform infrastructure.
• Strong expertise in database design, query optimization, and managing data at scale.
• Proficient in TypeScript, Node.js, React, Next.js, and Postgres.
• Experience building developer-facing infrastructure: APIs, SDKs, or internal tooling.
• Pragmatic technical decision-making: balancing technical excellence with business impact.
• Strong operational instincts: monitoring, alerting, debugging, and incident response.
• Excellent communication-translate complex technical concepts for various audiences.
• Startup experience preferred-you've built 0-to-1 products or scaled through hypergrowth.
• Bonus: Experience with AI/ML infrastructure, LLM APIs, or vector databases.
• Bonus: Open source contributions or technical writing demonstrating expertise.
