Do you want to superpower engineering with AI? At Monolith AI, we help engineering teams turn complex test and simulation data into better decisions, faster. As we scale our customer delivery, we’re looking for a Lead Customer Success Engineer to act as a technical delivery lead on client engagements.

This role is for someone who enjoys owning complex, customer-facing delivery -designing end-to-end solutions, coordinating multiple workstreams, and translating technical execution into clear customer value.

You’ll be responsible for:

· Coordinating execution across internal teams (product, data science, software, forward deploy)

· Translating technical progress into clear, customer-facing updates and reports

· Acting as a trusted technical advisor to senior customer stakeholders

· Getting hands-on where needed to unblock delivery or validate technical approaches

A bit about you

· You have a strong engineering or scientific background and can go deep when required

· You enjoy designing solutions, not just executing predefined tasks

· You communicate clearly and confidently with both technical and non-technical stakeholders

· You work well autonomously but thrive in cross-functional environments

It’s a bonus if you have

· Experience applying AI/ML or data science in an engineering context

· A Physics, Maths, or Engineering degree
