The Role

We are hiring a Developer Support Engineer to serve as the technical front line for our entire customer base, ranging from Fortune 500 enterprises managing critical workloads to Pro users utilizing our self-service platform. You will blend customer-facing technical work with hands-on debugging and engineering, owning issues end-to-end and driving direct impact on customer outcomes.

What Success Looks Like

• Act as the trusted technical contact for Enterprise and Pro users, earning their confidence through expert problem-solving.
• Analyze logs, traces, execution output, agent behavior, and integrations to diagnose customer-reported issues efficiently.
• Systematically reproduce issues to isolate root causes and deliver clear paths to resolution.
• Submit high-quality engineering tickets with thorough context or implement fixes directly when appropriate.
• Own escalations end-to-end, maintaining clear communication and driving issues to resolution.
• Identify patterns across support cases that reveal opportunities for product improvements.
• Become fluent in how Blitzy’s agent-driven system works, enabling faster diagnosis over time.
• Represent the voice of the customer in Engineering and Product discussions.
• Produce clear documentation, workarounds, and recommended practices that prevent future issues.
• Help establish the standards and processes that will scale our support function.

Areas of Ownership

• Customer Technical Support
• Primary technical contact for Enterprise and Pro users
• Investigation and diagnosis of platform issues
• End-to-end ownership of escalations
• Creation of workarounds and recommended practices
• Technical Investigation
• Log analysis, trace analysis, and debugging
• Issue reproduction in local and staging environments
• Root cause identification across distributed systems

• Direct implementation of fixes when appropriate
• Collaboration on reliability improvements and agent behavior tuning
• Representation of customer needs in product discussions
• Process Building

• Pattern identification for proactive improvements
• Foundation-setting for support engineering as we scale

Required Experience

• 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
• Curiosity and resourcefulness in learning complex systems
• Excitement about onsite collaboration with engineering and product teams

What Makes You Stand Out

• Familiarity with cloud infrastructure, containers, CI/CD, or modern DevOps tooling
• Experience with AI/ML systems or model-driven automation
• Contributions to open-source projects or internal tooling
• Background in customer-facing engineering roles
• Track record of translating customer feedback into product improvements

What Makes This Role Different

• You are not just answering tickets—you are building the technical support function from the ground up at a category-defining AI company.
• You have direct exposure to cutting-edge agentic AI systems and how thousands of autonomous agents collaborate to build production software.
• You will have real engineering ownership: when you find a fix, you can ship it.
• You will sit at the intersection of Engineering, Product, and Customer—your voice shapes the roadmap.
• You have a clear growth path as the support organization scales alongside one of the fastest-growing AI companies in the U.S.
• You receive a competitive equity package in a tier-1-backed startup with proven founders.

• We are led by two pioneering co-founders and are one of the fastest-growing companies in the U.S., creating our own category of enterprise autonomous software development.
• We automate thousands of hours of software development for our customers, including strong representation within the Fortune 500.

• We operate like a professional sports team. We win as a team by holding ourselves and each other to high standards, collaborating in-person, and remaining focused on the mission.
• We are passionate about invention, pushing the frontier of what’s possible, requiring constant innovation and iteration.
• We focus on delivering outsized value to the customers we work with and expanding those relationships into deep, meaningful partnerships. We believe in being 'everyday athletes'—taking care of ourselves so we can bring our best minds to work. We promote great sleep, movement, and restorative activities for optimal mental performance. It makes for a happier and more productive team.
• We are an equal opportunity employer committed to building a diverse and inclusive team. We believe different perspectives make us stronger.
