Developer Support Engineer

Technical Support EngineerKombo (YC S22) is building a unified API that saves engineering teams hundreds of hours by integrating dozens of HRIS, ATS, and Payroll systems into one API.We're looking for a Technical Support Engineer to provide exceptional technical assistance to our rapidly growing customer base, debug complex integration issues, and help shape the foundation of our support function in the U.S. You'll be the technical bridge between our customers and our product / engineering teams.In this role, you'll act as a Developer Support Engineer, not a Support Agent — solving most issues directly and collaborating with our engineering team on more complex ones.Day-to-day:Troubleshooting & Debugging: Investigate API integrations, data-sync issues, authentication flows (OAuth, API keys), and provider-specific edge cases.Customer Guidance: Assist customer engineers via Slack, email & occasional video calls — clear, concise, and technical.Internal Collaboration: Work closely with Product & Engineering to escalate bugs, relay feedback, and shape fix priorities.Knowledge Building: Create and maintain internal / external docs and guides based on recurring topics.Process Improvement: Set up better tooling, automation, and reporting to scale our support capabilities.Example projects:Debugging why new hires aren't syncing correctly from a customer's ATS (via Kombo) and fixing a mapping edge case.Helping a customer engineer resolve an OAuth 2.0 connection flow issue.Spotting a commonly misunderstood API parameter and collaborating with Engineering to improve docs or design.Building dashboards or alerts to proactively monitor integration health.Implement smaller new features across the codebase based on your findingsTech you'll work with: APIs (REST + SOAP + OAuth), Node.js, TypeScript, SQL, GCP (logs & monitoring), and various HRIS / ATS / Payroll systems + Kombo's own troubleshooting tools.Who We're Looking ForYou're a technically adept problem-solver with strong communication skills and a builder's mindset.You might be a great fit if you:Have a solid technical background (Software Engineer, Support Engineer, Solutions Engineer, etc.) and enjoy debugging APIs & integrationsYou can navigate large, unfamiliar codebases. You're comfortable digging into code you didn't write and don't yet fully understand, tracing data flows and logic across a large production codebase to find the root cause.You can write production code. You've shipped code to production before — whether as a software engineer, by building production-ready products, or by debugging and shipping fixes to live systems. Ideally in TypeScript / JavaScript, but strong experience in another modern language (e.g., Go, Python) works too.Communicate clearly and can explain technical concepts to engineers and non-engineers alikeAre empathetic and patient — you enjoy helping others solve problemsThrive with autonomy, take initiative, and drive your own projectsLike structured, high-performance environments and prefer working in person (we're an in-office culture)Prior experience in a technical support role is a plus but not required.What It's Like to Work at KomboOur culture balances high ambition with a fun, supportive environment.A few things that define us:Our growth puts us in the top 5 % of VC-backed companies and we plan to keep that paceWe keep teams small and high-performing (similar to Netflix or Ashby)We use long-form docs to make key decisions — clarity > meetingsWe celebrate weekly — big launches, closings, or birthdaysOur Engineering Meme culture is legendary internallyClosingIf joining a team with closeness and ownership potential of an early-stage startup while also having the upside of an already established, dominating product sounds appealing, you should apply — even if you don't tick every boxWe're excited to meet you!
