Developer Support Engineer

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.

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.

- 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

- Collaboration on reliability improvements and agent behavior tuning

- 2-5 years of experience in software engineering, technical support, platform support, or a debugging-heavy technical role

- Strong problem-solving skills with ability to analyze logs, traces, stack traces, APIs, and distributed systems behavior

- Comfortable reading and modifying code (Python or TypeScript strongly preferred)

- Excellent communication skills with both technical and non-technical audiences

- Ability to remain calm under pressure during escalations or complex customer situations

- Excitement about onsite collaboration with engineering and product teams

- Experience supporting developer tools, APIs, SDKs, or enterprise software platforms

- Familiarity with cloud infrastructure, containers, CI/CD, or modern DevOps tooling

- Track record of translating customer feedback into product improvements

- You're not just answering tickets-you're building the technical support function from the ground up at a category-defining AI company

- Direct exposure to cutting-edge agentic AI systems and how thousands of autonomous agents collaborate to build production software

- You'll have real engineering ownership: when you find a fix, you can ship it

- You'll sit at the intersection of Engineering, Product, and Customer-your voice shapes the roadmap

- Clear growth path as the support organization scales alongside one of the fastest-growing AI companies in the U.S.

- Competitive equity package in a tier-1-backed startup with proven founders
