About the Team

트웰브랩스의 멀티모달 임베딩 모델 Marengo의 연구개발을 담당하는 팀입니다. 비디오, 오디오, 텍스트 등 다양한 모달리티를 하나의 임베딩 공간(Embedding Space)에 통합하는 모델을 연구하고 개발합니다.

Contrastive learning, temporal video understanding, multimodal representation learning 등 다양한 연구 주제를 다루며, 대규모 학습 데이터 파이프라인 구축부터 모델 아키텍처 설계, 분산 학습 최적화, 평가 체계 설계까지 모델 개발의 전 과정을 책임집니다. NVIDIA B300 등 세계 최고 수준의 GPU 리소스에 대한 접근 권한을 바탕으로 대규모 실험을 빠르게 수행합니다.

연구에서 프로덕션까지의 간극이 매우 짧은 환경에서, Search, Product, Infrastructure 팀과 긴밀히 협업하며 전 세계 수천 고객이 사용하는 모델의 품질을 지속적으로 향상시킵니다.

About the Role

As an ML Research Engineering Manager on the Marengo team, you will build and lead the research engineering group responsible for TwelveLabs' multimodal embedding models, owning both the team's technical roadmap and the growth of the engineers on it.

This is a player-coach role. You will manage a team of ML research engineers working on model architecture, training infrastructure, and data pipelines, while staying technically engaged enough to make sound architectural decisions and evaluate research direction. We're looking for someone who has built and shipped production ML systems themselves, and now wants to multiply their impact by enabling a team to do the same.

In this role, you will

Manage and develop a team of ML research engineers: hire, onboard, run 1:1s, drive career growth, and build a high-performance engineering culture
Own the team's technical roadmap and execution plan, aligning research priorities with product and business goals
Define team structure, hiring plans, and resourcing across next-generation model development and training operations
Make key technical trade-off decisions across model architecture, training methodology, data strategy, and infrastructure investment
Drive hiring: define role profiles, evaluate candidates, and build a pipeline of strong research engineers
Ensure research quality and engineering rigor through design review, experiment review, and setting clear standards for reproducibility and evaluation
Coordinate cross-functionally with Search, Product, and Infrastructure teams on model integration, timelines, and dependencies
Remove blockers, manage scope, and keep execution focused on highest-impact work

You may be a good fit if you have

7+ years of industry experience in ML engineering or research engineering, with at least 2 years managing engineers or tech-leading a team
Hands-on background building and shipping production ML systems: you've done the work yourself before asking others to do it
Strong technical foundation in representation learning, contrastive learning, or large-scale model training, deep enough to evaluate research direction and make architectural calls
Experience hiring and growing ML engineers: you've built teams, not just inherited them
Track record of translating ambiguous research goals into concrete team roadmaps with clear milestones
Strong communication skills: you can represent the team's work to leadership, align with cross-functional partners, and give direct, constructive feedback
Proficiency in Python and PyTorch; you can still read and review code and experiment designs

This role is a strong fit for someone with an MS and deep industry experience who has transitioned from a top-performing IC into engineering leadership: someone who chose management because they wanted to multiply impact through people, not because they stopped wanting to be technical.

Preferred Qualifications

Experience managing research-oriented engineering teams (not just pure software engineering)
Experience scaling a team through a high-growth phase (hiring 3+ engineers in a year)
Experience with distributed training infrastructure and training operations at scale
Background in multimodal learning, video understanding, or information retrieval
Experience running performance cycles, calibrations, and career development frameworks
Prior startup experience: comfort with ambiguity, speed, and wearing multiple hats

What makes this role unique

The gap between research and production is remarkably short here. Models you build will be used by thousands of companies worldwide within months. We work as a unified team toward the broader goal of video understanding, rather than solving isolated problems. Our research philosophy balances rigorous experimentation with real-world application: we aim to build multimodal systems that are powerful, trustworthy, and genuinely useful.

Others

Work Location: Seoul Itaewon office + Pangyo satellite office

Even if you don't check every box, we encourage you to apply. If you're a zero-to-one achiever, a ferocious learner, and a kind team player who motivates others, you'll find a home at TwelveLabs.
