Who we are:

Our name is inspired by Theodore Roosevelt’s ‘Citizenship in a Republic’ speech, which pays homage to the ‘(hu)man in the Arena’. To us, entering the Arena means committing oneself fully and accepting the risk of failure in the pursuit of an audacious, worthy cause.

We’re a close-knit tribe of scientists and builders exploring the boundaries of how artificial intelligence can benefit humanity. If you share our passion for delving deep into real-world problems and solving them with fully autonomous AI, join us in the Arena.

What we do:

Our collective future is being built in the physical world, but the builders of tomorrow’s technology can no longer rely on yesterday’s tools. At Arena, we’re building the world’s first AI industrial engineer designed to solve the most complex hardware and manufacturing challenges. Our product, Atlas, is built with an understanding of the behavior of physical systems, powered by a superior knowledge of core domains of physics. Paired with its ability to reason about multimodal industrial data, Atlas can test, debug, optimize, and repair physical systems and products in the real world. Arena is already trusted by some of the most advanced industrial companies in the world (AMD, Bausch & Lomb), and we're rapidly already scaling into the defense, automotive, and pharmaceuticals industries, and we’re just getting started.

About the role:

Our engineering team works directly with customers to solve complex, mission-critical challenges using Arena’s cutting-edge products and technologies. Engineers own the full solution lifecycle—from problem identification, designing and implementing data-driven solutions, to demonstrating their value in real-world scenarios.

As a Software Engineer, Growth, you'll operate like a startup CTO. You’ll work closely with both customers and Arena teams to build end-to-end systems in small, agile teams, working on fast timelines. Your responsibilities will include designing systems, analyzing large datasets, developing tailored applications on top of Arena’s product stack, interacting with users, and training AI models.
By addressing specific customer challenges, you will play a pivotal role in refining and scaling Arena’s products, contributing to their broader adoption and success.

This is a unique opportunity to gain hands-on experience in driving innovation across some of the world's most vital industries, making it ideal for those aspiring to become entrepreneurs or future engineering leaders.

How you will contribute:

• Prototype moonshot ideas and push the boundaries on what is possible. 
• Spearhead the development of the next generation of machine learning software with a focus on Core Intelligence (ML Modeling), Telemetry (Impact & Algorithmic Health), and AI interfaces.
• Drive the development of new features or custom applications by either extending Arena's products or creating tailored solutions.
• Travel both domestically and internationally up to 50% of your time.
• When not traveling, you will work in-person at Arena's NYC headquarters.

You Have:

• Demonstrated enthusiasm and knowledge of Artificial Intelligence and Machine Learning concepts.
• Proven ability to write clean, efficient code.
• Instinct to break down complex problems into small building blocks.
• Strong communication skills with empathy for end-users, ensuring usability across UI, API, and SDKs

Benefits & Perks Include:

• 99% of the monthly premium for Aetna medical insurance, plus vision and dental coverage
• 401(k) Retirement Plan
• Unlimited PTO
• Lunch every day from local restaurants via Sharebite

The base salary range for this position is $150,000 - $225,000 yr. However, base pay offered may vary depending on job-related knowledge, skills, and experience. In addition to base salary, we also offer competitive equity and benefits packages.
