Build the technical foundation of customer support for the platform transforming enterprise software development

Blitzy is a Cambridge, MA based Generative AI startup on a mission to automate custom software creation to unlock the next industrial revolution. We're transforming how enterprises build software—turning human ideas into production-ready applications with AI that can autonomously generate up to 80% of enterprise-grade code.

We're backed by tier 1 investors and led by founders with deep expertise in AI and enterprise software. Our platform doesn't just suggest code snippets—it builds complete, production-ready applications that enterprises can deploy immediately.

Compensation: $125,000 - $135,000 plus equity

Location: 1 Kendall Square, Cambridge, MA (Onsite role)

We're hiring a Developer Support Engineer to serve as the technical front line for our entire customer base—from Fortune 500 enterprises running mission-critical workloads to Pro users building on our self-service platform. This role blends customer-facing technical work with hands-on debugging and engineering, offering strong ownership and direct impact on customer outcomes.

You'll investigate complex issues, analyze logs and code, identify root causes, and implement fixes directly in the product when appropriate. This is an ideal role for someone who wants exposure to real-world codebases at scale while shaping the foundations of our support engineering function.

• You act as the trusted technical contact for Enterprise and Pro users, earning their confidence through expert problem-solving
• You diagnose customer-reported issues efficiently by analyzing logs, traces, execution output, agent behavior, and integrations
• You reproduce issues systematically to isolate root causes and provide clear paths to resolution
• You submit high-quality engineering tickets with thorough context—or implement fixes directly when appropriate
• You own escalations end-to-end, maintaining clear communication and driving issues to resolution
• You identify patterns across support cases that reveal opportunities for product improvements
• You become fluent in how Blitzy's agent-driven system works, enabling faster diagnosis over time
• You represent the voice of the customer in Engineering and Product discussions
• You produce clear documentation, workarounds, and recommended practices that prevent future issues
• You help establish the standards and processes that will scale our support function
