Impact You'll Have

• Own mission-critical surfaces end-to-end from API to UI that revenue leaders use daily to convert leads to revenue.

• Turn customer feedback into shippable specs and ship quickly, improving quality while shrinking lead time for change.

• Raise the reliability bar (observability, testing, fallbacks) so complex AI features behave predictably in high-stakes moments.

• Help build the leading voice AI platform for GTM teams.

Required Experience

• 5+ years of experience building production-grade applications.

• Strong expertise with modern JavaScript/TypeScript, and React. Experience with Golang.

• Knowledge of DevOps practices.

• Background in building secure, compliant systems.

• Experience with AI/LLM integrations

• Understanding of GTM tech or B2B SaaS.
