About Letter AI

Letter AI is the world’s first revenue enablement platform powered natively by AI. We’re reimagining the end-to-end revenue journey by turning real customer conversations and account data into actionable insights, personalized coaching, meeting prep, and next steps.

Revenue teams aren’t asking for more content or tools. They’re asking for better outcomes. Letter does just that, empowering them to learn faster, sell smarter, and win more.

We recently raised a $40M Series B and are already helping leading companies like Adobe, Lenovo, and Figma transform how their teams work. We 10xed our revenue last year and are looking for the best of the best in Chicago to help us build on that momentum.

The Role

We are looking for a Support Engineer to join our team and be the technical front line for our customers. You will own customer-reported issues end to end — diagnosing problems, working directly with our engineering team to resolve them, and helping shape a product that gets better with every ticket. This is a hands-on, high-impact role at an early-stage company, where the support function itself is still being built and you'll have real influence over how it works.

Your key responsibilities will include:

• Serve as the primary technical point of contact for customer-reported issues, troubleshooting problems across our web app, integrations, and APIs
• Reproduce, diagnose, and triage bugs, distinguishing between user error, configuration issues, and genuine product defects
• Partner closely with engineering to escalate, track, and resolve technical issues, providing clear reproduction steps and context
• Monitor support channels and ensure timely, high-quality responses that meet our SLAs
• Build and maintain internal documentation, FAQs, and troubleshooting guides to reduce repeat issues
• Identify patterns across customer issues and proactively flag product improvements to engineering and product teams
• Support customer onboarding and technical enablement as needed
• Use logs, dashboards, and SQL to investigate the data and system behavior behind reported issues

Qualifications for the role include:

• 2-4 years of experience in a technical support, support engineering, or software engineering role, ideally at a B2B SaaS company
• Strong troubleshooting and debugging skills, with comfort reading code (Python, JavaScript/TypeScript) even if you're not writing production features day to day
• Familiarity with APIs, web applications, and basic database/SQL concepts
• Excellent written and verbal communication skills, with the ability to explain technical concepts clearly to both customers and engineers
• Highly organized, with strong ownership of customer issues from first report through resolution
• Past experience or strong interest in generative AI
• Highly collaborative mindset with strong problem-solving skills
