Kyber (YC W23) Is Hiring a Head of Engineering

Kyber is an AI-native enterprise document platform focused on automating complex regulatory notices for regulated industries like insurance. The startup, YC W23-backed and profitable after 40x revenue growth, has secured multiple six- and seven-figure multi-year contracts and partnerships with Guidewire, Majesco, and Twilio Sendgrid. Its product consolidates templates, speeds drafting, and shortens communication cycles by roughly 5x, serving small engineering team operations out of New York City. The Head of Engineering role offers $220K-$280K plus 0.50%-1.50% equity, requires US work authorization and 6+ years’ experience, and includes full employer-covered medical, dental, and vision benefits.

The position is hands-on and reports near the CTO, owning end-to-end technical decisions across backend, frontend, data, and infrastructure while personally shipping features and unblocking the team. Key responsibilities include driving an aggressive product roadmap, scaling Agentic AI coding tools (Cursor, Claude Code, Greptile) into workflows, establishing reusable patterns, and owning reliability, security, and compliance (SOC 2, HIPAA, ISO). Candidates must demonstrate exceptional coding ability, system-design mastery, systems-first thinking, accountability in managing others, and enterprise compliance experience. The interview sequence includes a founder screen, take-home, technical deep dive, system-design scaling, leverage & leadership rounds, and five references; referrals with a 2-3 sentence endorsement to the founder are encouraged.
