Partner Engineer

About the role

The Partner Engineer serves as the primary technical liaison for Parafin's most critical platform integrations, owning the full lifecycle of partner implementations from initial scoping through sustained production support. This role demands fluency in both deep technical execution and consultative communication, as you translate complex platform capabilities into reliable integration solutions for external partners. You will act as the hands-on counterpart on the post-sales side, directly responsible for driving technical onboarding, resolving cross-team blockers, and ensuring seamless operation of integrated products in production environments. This position requires a builder who thrives on ownership, who can balance strategic influence with tactical debugging across distributed systems. You will shape Parafin's technical GTM by capturing real-world feedback and translating it into product and API improvements that strengthen our platform moat. The role is mission-critical to scaling our partner network with speed and excellence.
