Job description

We’re looking for a Lead Developer (Full Stack) to own the product layer of our system. You’ll be responsible for the frontend experience and the API/application layer—working across the stack to deliver reliable, end-to-end product workflows. You’ll collaborate closely with backend/data engineers and SRE, shaping how systems come together at the product layer, and contributing wherever needed to ship features. You’ll play a key role in moving us from early deployments to a repeatable product across multiple facilities. This is a high-ownership role. You will define patterns, unblock teams, and help shape how the product works—not just how it’s implemented. We've found tremendous value in collaborative problem-solving, so our team works from our SF office three days a week.

Key Responsibilities

• Drive the development of our frontend (Next.js / TypeScript), leveraging modern code-generation agentsArchitect and oversee the API/application layer, focusing on system integration, security, and data integrity
• Design robust end-to-end product workflows, acting as the primary reviewer and quality gatekeeper for automated code contributions
• Implement strict automated testing and CI/CD pipelines to ensure reliability and safety of the features
• Build and maintain:
  • Customer-facing UI for live operations and analytics
  • Internal tools for configuring and deploying facilities
• Collaborate with product to translate high-level requirements into concrete workflows and implementations
• Collaborate with backend engineers to define and evolve API contracts and data interactions
• Improve performance, reliability, and maintainability of the frontend
• Implement and maintain frontend and API testing and CI workflows
• Own authentication flows and system integration at the product layer

Required Qualifications

• Strong experience with TypeScript and React (Next.js or similar)
• Experience building and maintaining API layers using backend frameworks (Python, Node, or similar)
• 5+ years building and shipping production systems
• Experience owning end-to-end features or products, not just isolated components
• Comfortable working across the stack (frontend + API layer)
• Strong ownership and product mindset, with the ability to operate in ambiguous, fast-moving environments

Preferred Qualifications

• Experience building real-time or data-heavy applications (e.g., streaming, time-series, or analytics systems)
• Experience working with authentication systems (e.g., login flows, session management, SSO integrations)
• Experience working with systems deployed outside pure cloud environments (e.g., on-prem, edge, or hardware-integrated systems)

How We Work with Product & Design

You will often start from high-level product goals, not detailed specifications. You’re expected to help define:

• workflows
• user interactions
• system behavior

You’ll collaborate with product and design, but also fill in gaps and move work forward independently

Why This Role Matters

We’re scaling from a small number of deployments to many, and this role is critical in making that happen. We need:

• A product layer that can support multiple facilities and configurations
• Internal tools that make deployments repeatable
• Clear workflows that work in real-world environments

Engineers who can move quickly without breaking the system

Equal Opportunity Statement

We’re an equal opportunity employer that values diversity and inclusion. We welcome teammates of all backgrounds and don’t discriminate based on race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status.

Benefits

At Claryo, we offer a competitive benefits package that supports your health and well-being, including — top-tier medical, dental, and vision coverage, 401k with employer matching, parental leave, and unlimited vacation.

Compensation Range: $165K - $180K
