Developer Support Engineer

Developer Support Engineer About Blitzy Blitzy is a Cambridge, MA based AI software development platform on a mission to revolutionize the software development life cycle by autonomously building custom software to unlock the next industrial revolution. We're transforming how enterprises build software, turning enterprise requirements into production-ready code with an agentic software development platform that can autonomously execute 80% of the quantum of software development work. We're backed by multiple tier 1 investors, and have proven success as founders of previous start-ups. Location: 1 Kendall Square, Cambridge, MA (Onsite) Compensation: $75,000 – $135,000 + equity The 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. You’ll blend customer-facing technical work with hands-on debugging and engineering, owning issues end-to-end and driving 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 real-world exposure to production codebases at scale while helping shape the foundations of our support engineering function. What Success Looks Like 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 deliver 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
