Join the One Elite Team Building AI Infrastructure.
We're looking for engineers who love going deep, all the way down to the silicon, and coming back up with something that changes how the world runs AI.
Our team is driven by our mission.
Powering a sustainable, high-performance future for the world's largest data centers. Through innovation, relentless research, and a world-class team. AI agents are rewriting what infrastructure needs to do. We're building the layer that makes agentic AI actually work at scale.
“We're a group of engineers who genuinely love optimizing systems. That passion is what makes our products different.”
What We Believe.
Top Talent
The best-in-class people who propel innovation and lead the entire competitive field. We hire for depth, not just credentials.

The aim to attain and sustain global leadership, delivering superior products and services through genuine technical breakthroughs.
Commitment
A strong devotion to excellence that empowers everyone to achieve their collective goals. We hold ourselves to the highest standard.
One Team
A cultivation of transparency and trust, fostering a close-knit community that collaboratively resolves differences and elevates ideas.
Life at MangoBoost.
Individual ownership. Collective knowledge.
We foster a work culture that promotes both individual responsibility and knowledge-sharing as a team. We're a group that's passionate about what we research and create, which shines through our quality of work.
Stay ahead. Keep building.
As we work to get ahead of the newest technologies, we focus on the constant professional and academic growth of our team. We challenge our teammates to take on important projects while providing the tools to continue developing as engineers.
Your work runs in the real world.
MLPerf world records. 400G DPU deployments in global data centers. Partnerships with Dell, Supermicro, AMD, and more. When you build here, it gets measured against the best benchmarks in the world. And it ships.
Voices from the Team.
MangoBoost is the rare place where research turns into real products. Seeing a prototype become something robust enough for industry use, something academia simply can't offer.
Rachata Ausavarungnirun
Senior Staff Engineer
What surprised me most was the ownership MangoBoost gives its engineers from day one. Even when the territory is unfamiliar, you're trusted to lead and that drives real growth.
Sahand Kashani
Hardware Engineer
We built MangoBoost from prototypes of key technologies, with people who were already leading the field. Watching that grow into a full suite of solutions, with customers we talk to directly, is what makes every day meaningful.
Eunjin Baek
Network Team Lead
The best part of working the business side of a deep-tech company: you're close enough to the technology that your decisions actually move the product. Not slides, real roadmap. And doing it as one team, people strong on both the tech and the business, ambitious and genuinely collaborative, is what makes it so fun.
Wonseok Lee
Strategy & Operations Team Lead
At MangoBoost, you'll work alongside some of the best engineers in the field, people who take real ownership and push each other to grow. My goal is to protect that environment. We're moving quickly to bring in exceptional talent so that great people can focus on what they do best and keep growing.
